Öğe A new method for diagnosis of anterior cruciate ligament tear: MRI with maximum flexion of knee in the prone position: A case control study(Elsevier Ltd, 2019) Günaydın, Burak; Şahin, Gülcan Güçer; Sarı, Abdulkadir; Kara, A.; Dinçel, Yaşar Mahsut; Çetin, Mehmet Ümit; Kabukçuoğlu, Yavuz Selim; Tekin, ÇağatayBackground: The diagnosis of anterior cruciate ligament tear can be made by physical examination and magnetic resonance imaging (MRI) in the supine position. In cases where the tear is partially evaluated on MRI, the choice of treatment may vary. The purpose of the study was to investigate the efficiency of MRI at maximum knee flexion in the prone position and to compare the images with findings of the ACL detected during surgery. Materials and methods: Sixty-one patients with partial ACL tears with meniscal and cartilage lesions requiring arthroscopic knee surgery were included in the study between 2017 and 2019. MRI of these patients was prescribed at maximum knee flexion in the prone position. Then, an arthroscopic operation was performed on 61 patients and the findings (intact, partial or total tear of ACL) were recorded. The ACL was evaluated as being intact and partial or total tear. The statistical significance of the efficacy of MRI in the supine position with the knee at maximum flexion in the prone position was compared. Results: It was found that, of 61 patients with suspected partial ACL tears, 25 patients had intact ACLs, 22 patients had partial tears and 14 patients had total ACL tears, through the interpretation of MRIs of the prone position by the radiologist. In the arthroscopic surgery of 61 patients, 20 patients had intact ACLs, 27 patients had a partial tear and 14 patients had a total tear. The MRI results with maximum knee flexion in the prone position were more compatible with the findings of the arthroscopic surgery. Conclusions: It could be considered that MRI with maximum knee flexion in the prone position may also be guiding in the diagnosis and treatment of patients with partial anterior cruciate ligament rupture. © 2019Öğe Analysis of the coracoid morphology with multiplanar 2D CT and its effects on the graft size in the Latarjet procedure(Sage Publications Ltd, 2020) Sarı, Abdulkadir; Sasani, Hadi; Çetin, Mehmet Ümit; Günaydın, Burak; Kılınç, Seyran; Yıldırım, İlker; Dinçel, Yaşar MahsutPurpose: In this study, we aimed to reveal the individual differences regarding the size of the coracoid and their effects on the classical and modified Latarjet procedures. Methods: Computed tomography images of 120 patients (mean age: 41.18 +/- 12.01 years) without shoulder complaints or shoulder instability were evaluated retrospectively. The glenoid width, the surgical graft length, and the coracoid total length, width, and thickness were measured using the multiplanar reconstruction method on the Sectra Picture Archiving and Communications System (PACS) system. Age, gender, side, the dominant hand, and the height of the patients were recorded and the correlations between them were investigated. On the created hypothetical model, the current size of the coracoid was evaluated to determine what size of glenoid defects it could repair by employing the classical and the modified Latarjet techniques. Results: There was no significant difference between the right-hand-dominant group and the left-hand-dominant group in terms of coracoid measurement results (p > 0.05). Again, there was no statistically significant difference between the right and the left side regarding the coracoid size (p > 0.05). A positive correlation could be detected only between age and the coracoid width and thickness (p < 0.05). A positive correlation was also found between the glenoid width and the coracoid width and thickness in both shoulders (p < 0.001). Coracoid thickness could fill in the defects that amounted to 40% of the glenoid width, while the coracoid width could fill in for the defects that were 50% of the glenoid width in both genders. Conclusion: Our study showed that hand dominance and side were not effective on the coracoid dimensions. In addition, it has been shown that the coracoid dimensions did not have a significant effect in the choice of Latarjet technique in terms of defect repair and that repair rates of up to 40% could be achieved in glenoid defects with both techniques.Öğe Assessment of the Glenoid Morphology Based on Demographic Data in the Turkish Population(Hindawi Ltd, 2020) Sarı, Abdulkadir; Dinçel, Yaşar Mahsut; Günaydın, Burak; Çetin, Mehmet Ümit; Özçağlayan, Ömer; Bilsel, KeremPurpose. In this study, our aim was to evaluate the glenoid version, height, and width measurements based on gender, side, age, height, and hand dominance in the Turkish population using computed tomography (CT) images. Methods. In our study, CT images of 140 patients (62 females and 78 males; mean age: 39.6 years) who had no shoulder complaints were evaluated retrospectively. Glenoid version (GV), AP diameter (width), and SI diameter (height) on both shoulders were measured on the CT images. Correlations between patient gender, side, age, height, and hand dominance and the GV and size were evaluated. Results. The right shoulder had a mean GV of -0.93 +/- 7.80 degrees and the left shoulder had a GV of -0.88 +/- 6.63 degrees (p>0.05). The mean AP diameter of the glenoid was 26.57 +/- 3.02 mm in the right shoulder and 26.33 +/- 3.01 mm in the left shoulder (p>0.05). The mean SI diameter of the glenoid was 31.8 +/- 3.6 mm in the right and 31.7 +/- 3.3 mm in the left shoulder (p>0.05). When men and women were evaluated in two separate groups, the GV, AP, and SI values did not exhibit a statistically significant difference between the two shoulders in both genders (p>0.05). There was a positive correlation between the ages and heights of the patients and the glenoid size (p<0.05). The mean AP diameter was approximately 28 mm and the SI diameter was 34 mm in males, whereas the mean AP diameter was 24 mm and the SI diameter was 30 mm in females (p<0.05). The GV values of the dominant shoulders were significantly more retroverted (p<0.05). There was a positive correlation between the ages and heights of the patients and the glenoid size (p<0.05). Conclusion. Hand dominance had an effect on the glenoid version, while patient gender, age, and height had an effect on the glenoid size. The glenoid width in the Turkish population was similar to that of the European and American populations, and the glenoid height was similar to that of the Asian population. Our GV values were similar to those of the Asian population and more anteverted compared to the Western population. We believe that our findings will be useful in preoperative planning and in the production of implants for our population.Öğe Can fracture healing be accelerated by serum transfer in head trauma cases? An experimental head trauma model in rats(Turkish Joint Diseases Foundation, 2021) Sarı, Abdulkadir; Dinçel, Yaşar Mahsut; Çetin, Mehmet Ümit; İnan, SevdaObjectives: In this study, we aimed to investigate whether the positive union effect caused by head trauma could be transferred between individuals.& nbsp; Materials and methods: Seventy-two male rats with an average weight of 375 g were used in this study and divided into four groups including 18 in each group. Group 1 consisted of serum donor rats that were exposed to head trauma, while Group 2 consisted of study rats with long bone fractures that were given the serum obtained from the rats in Group 1, Group 3 included control rats with isolated long bone fractures, and Group 4 included control rats with both head trauma and long bone fractures. For radiological evaluation, the ratio of the width of the callus to the width of the neighboring diaphysis was considered as the callus-todiaphyseal ratio in the study and control groups. Histopathological and radiological evaluations was made on Days 10, 20, and 30.& nbsp; Results: In evaluation of the radiological data regarding the callusto-diaphyseal ratio, Group 3 was found to have significantly lower radiological values than Group 4 on Day 10 (p=0.006). Group 2 had significantly higher values than Group 3 (p=0.02). On Day 20, Group 2 exhibited significantly higher radiological values than Group 3 (p=0.004), but lower than Group 4 (p=0.032). As for Day 30, Group 2 exhibited significantly higher radiological values than Group 3, but lower than Group 4 (p=0.001). In the evaluation of the Huo scores obtained for histopathological evaluation, there was no significant difference among the groups on Days 10, 20, and 30 (p=0.295, p=0.569, and p=0.729, respectively).& nbsp; Conclusion: Our study results suggest that the osteoinductive effect after head trauma can be transmitted between individuals by means of serum transfer.Öğe Changes in Bone Mineral Density After Total Knee Arthroplasty(Atha Comunicacao & Editora, 2020) Dinçel, Yaşar Mahsut; Sarı, Abdulkadir; Tekin, Çağatay; Günaydın, Burak; Çetin, Mehmet Ümit; Arslan, Yunus ZiyaObjective: We aimed to investigate the change in bone mineral density (BMD) in the first postoperative year in patients that underwent total knee arthroplasty (TKA) due to primary osteoarthritis of the knee. Methods: Preoperative and first postoperative year dual-energy X-ray absorptiometry measurements of 76 patients with knee osteoarthritis, who undergone surgery between 2016 and 2018 due to the recommendation for TKA, were statistically evaluated in the study. Results: Of the 19 patients with a normal BMD in the preoperative period, 73.7% (n = 14) continued to have a normal BMD in the postoperative period. Of the 34 patients with a low BMD (osteopenia) in the preoperative period, 91.2% (n = 31) did not show any change, whereas osteoporosis was observed in two patients (5.9%) in the postoperative period. Of the 23 patients with osteoporosis in the preoperative period, 95.7% (n = 22) did not show any change, whereas osteopenia was observed in one patient (4.3%) in the postoperative period. Both the T and Z scores of the spine (L1-L4) and proximal femur showed a slightly positive trend, however, with an insignificant statistical difference (p >= 0.05). Conclusion: Patients that underwent TKA experienced a statistically insignificant bone gain at the spine and proximal femur twelve months after the surgery.Öğe Comment on: the Influence of Bone Loss on Glenoid Version Measurement: A Computer-Modeled Cadaveric Analysis(W B Saunders Co-Elsevier Inc, 2019) Sarı, Abdulkadir; Dinçel, Yaşar Mahsut[No Abstract Available]Öğe COMPARISON OF CHANGES IN THE ANKLE AFTER UNICONDYLAR KNEE ARTHROPLASTY AND HIGH TIBIAL OSTEOTOMY(Atha Comunicacao & Editora, 2022) Sarı, Abdulkadir; Dinçel, Yaşar Mahsut; Çetin, Mehmet Ümit; Kılınç, Seyran; Günaydın, Burak; Özdemir, MikailObjectives: We aimed to compare the changes in the coronal alignment of the ankle joints and their clinical effects after high tibial osteotomy (HTO) and unicondylar knee arthroplasty (UKA). Methods: 50 HTO and 54 UKA patients who were operated on for medial knee osteoarthritis between 2013 and 2018 were retrospectively evaluated. The hip-knee-ankle angle (HKA), the medial proximal tibial angle (MPTA), the tibial plafond inclination (TPI) and the talar inclination (TI) angles were measured before and after operation. Visual analog scale (VAS), short form 36 (SF-36), and ankle-hindfoot scale (AHS) scores of both groups were evaluated and recorded. Results: Angular changes in the HKA, MPTA, TPI and TI values showed significantly greater values in the HTO group (p<0.001). When asymptomatic and symptomatic cases were compared, it was found that changes in the HKA, TPI and TI values were significantly greater in symptomatic cases in the HTO group (p<0.05). A significant decline was observed in the VAS, SF-36 and AHS scores in the HTO group in the postoperative period (p<0.05). In intergroup evaluations, a significant decline was detected in pain and functional scores of the HTO group when compared to the UKA group (p<0.05). Conclusion: Unicondylar knee arthroplasty can be a good alternative to HTO in selected cases for postoperative ankle complaints.Level of Evidence III; Therapeutic Studies Investigating the Results of Treatment.Öğe Comparison of the prophylactic use of ibandronate and its use in early-stage osteonecrosis in rats with steroid-induced osteonecrosis of the femoral head(2023) Çağlar, Sever; Daşçı, Mustafa Fatih; Acar, Abdurrahman; Çağlar, Aysel; Dinçel, Yaşar Mahsut; Çataltepe, AzizObjectives: The aim of this study was to investigate the effects of ibandronate before and after the onset of osteonecrosis in rats with steroid-induced osteonecrosis of the femoral head. Materials and methods: A total of 24 female Sprague-Dawley rats were used in this study. Three groups were formed with eight rats in each group. The first group was the prophylactic group that received ibandronate treatment before and after the onset of osteonecrosis (Group PT). The second group received ibandronate treatment three weeks after the development of osteonecrosis (Group TAO). The third group was the control group in which osteonecrosis was created, but only normal saline (NS) was given. At the end of the study, all rats were sacrificed, and their right femoral heads were removed, fixed with formalin, and sent for micro-computed tomography. Hematoxylin-eosin (H&E) and immunohistochemical examinations of the right femoral head sections were performed. Results: In the PT group, the trabecular thickness was significantly higher compared to those of the TAO and control groups (pÖğe Corrigendum to "A new method for diagnosis of anterior cruciate ligament tear: MRI with maximum flexion of knee in the prone position: A case control study" (International Journal of Surgery (2019) 68 (142-147), (S1743919119301451), (10.1016/j.ijsu.2019.06.017))(Elsevier Ltd, 2020) Günaydın, Burak; Şahin, Gülcan Güçer; Sarı, Abdulkadir; Kara, A.; Dinçel, Yaşar Mahsut; Çetin, Mehmet Ümit; Kabukçuoğlu, Yavuz Selim; Tekin, ÇağatayThe authors regret that the figure captions in this article appeared incorrectly and should have been displayed as follows: Fig. 3.

The most common injured knee ligament is the anterior cruciate ligament (ACL) in sport injuries. Accordingly, surgical treatment of the ACL is performed frequently. In this study, it was aimed to retrospectively evaluate whether the location of an endobutton on lateral knee radiography was effective on knee functional scores in patients who underwent ACL reconstruction. Materials and methods One hundred thirty patients who underwent ACL reconstruction between January 2015 and February 2019 were identified. The patients were divided into three groups according to the location of the endobutton on lateral radiographs taken in the postoperative period. Group 1 patients were classified as anterior, group 2 as middle, and group 3 as posterior according to the location of the endobutton. Functional scoring, physical examination tests, comparative thigh diameter measurements, and single-leg hop tests were compared between the groups. It was evaluated as to whether there was a statistically significant difference between the groups. Results There were 38 patients in group 1, 63 patients in group 2, and 29 patients in group 3. The mean age was 29.1 in group 1, 29.1 in group 2, and 29.7 in group 3. The mean follow-up period of the patients was 18.4 months in group 1, 19.1 months in group 2, and 21.4 months in group 3. The average Lysholm score was 92.9 in group 1, 93.3 in group 2, and 91.7 in group 3. The mean modified Cincinnati scores were 27.0, 27.1, and 26.6, respectively, in the groups. The mean IKDC score of the subjective knee assessments was 92.5, 92.8, and 91, respectively, according to the groups. The average thigh atrophy value was 1 cm, 1 cm, and 1.2 cm, respectively, in the groups. In the single-leg hop test, 34 patients in group 1 jump to over 85% of the distance compared with the intact side, while 58 patients in group 2, and 23 patients in group 3 were successfully able to jump this distance. The effect of the placement of the endobutton in the anterior, middle or posterior was not statistically significant on functional scores and physical examination results. In patients with endobuttons in the middle, functional scores were found better than in those with anterior or posterior placement. Conclusions No statistically significant differences were found in clinical functional results when comparing patients' endobutton location on femur. For this reason, surgical time should not be extended using unnecessary extra effort to change the orientation of the exit hole during surgery.Öğe Effect of demographic features on morphometric variables of the knee joint: Sample of a 20 to 40-year-old Turkish population(Lippincott Williams and Wilkins, 2023) Gültekin, M.Z.; Keskin, Z.; Dinçel, Yaşar Mahsut; Arslan, T.This study aimed to investigate the relationship between body mass index (BMI), age, and sex and morphological risk factors that may cause internal knee injuries. The magnetic resonance images of 728 participants who met the inclusion criteria and had a mean age of 34.4?±?6.8 years were analyzed retrospectively. Demographic differences were analyzed by measuring 17 morphological parameters known to be associated with internal knee injuries. Men had a higher anterior cruciate ligament length (ACLL), anterior cruciate ligament width, (ACLW) lateral femoral condylar width (LFCW), medial femoral condylar width (MFCW), lateral femoral condylar depth (LFCD), distal femoral width (DFW), and intercondylar femoral width (IFW) than women (P?Öğe Have the online patient information materials on biceps tendon disorders adequate, quality and readability?(2023) Gültekin, Muhammet Zeki; Dinçel, Yaşar Mahsut; Doğar, Fatih; Arslan, SerdarAim: The study aimed to analyze the quality, adequacy and readability of websites created for patients with shoulder complaints associated with biceps tendon disorders. Methods: The terms 'shoulder injury', 'biceps tendinitis' and 'biceps tendon rupture' were searched in the most used search engines in United States (Google, Yahoo, and Bing). One hundred forty seven websites designed to inform patients were included in the study. The quality, popularity, adequacy and reliability were meausured. Results: Flesch reading ease scores of websites with content creation by health professionals were significantly lower than those without; in contrast, Flesch-Kincaid grade level (FKGL) and Koleman-Liau index scores were significantly higher (p<0.05). Global Quality Score and originality scores were greater in website created by health professionals. In addition, the percentage of websites with reference citations and addressing the importance, symptoms, treatment, signs and mechanism of the disease was significantly higher in websites with content creation by health professionals than in those without (p<0.05). The Gunning Fog, FKGL, Simple Measure of Gobbledygook, Automated readability index and Linear write formula scores were lower for websites with the HON code than those without the HON code. Also orginality score and Alexa Popularity Rank (APR) scores were lower in websites with HONcode than without HON code (p<0.05). Conclusion: Websites with HON code and prepared by healthcare professionals can provide sufficient and quality information to patients with biceps tendon disorders. The web content available for biceps tendon disorders is above the recommended reading level. Health professionals should be encouraged to increase the readability of the content.Öğe Histopathological and immunohistochemical investigation of the local and systemic effects of tranexamic acid on the healing of the Achilles tendon in rats(Turkish Joint Diseases Foundation, 2021) Sarı, Abdulkadir; Dinçel, Yaşar Mahsut; Karabağ, Sevil; Çetin, Mehmet ÜmitObjectives: This study aims to compare the effects of systemic and local applications of tranexamic acid (TXA) on tendon healing using a rat Achilles tendon injury model. Patients and methods: Thirty-six adult male albino Wistar rats (aging 3-4 months; weighing 350 to 400 g) were used in this study conducted between December 2019 and January 2020. The Achilles tendon was performed bilateral tenotomy and surgically repaired. Postoperatively, 1 mL of TXA was administered to each leg locally in the local group, whereas 2 mL of TXA was intraperitoneally administered in the systemic group. The control group was left untreated. Half of the rats were sacrificed on Day 15 and the other half on Day 30. Tendon healing was evaluated with the Bonar and the Movin scoring systems and immunohistochemical methods. Results: The systemic group had the highest Bonar and Movin scores on Day 15. All groups exhibited tendon healing on Day 30, with no significant differences among the groups. The tenocyte morphology was found to be more impaired in both TXA groups on Day 30 (p=0.013). Ground substance scores were lower in the systemic group on Day 30 (p=0.028). The fiber structure and arrangement scores were higher in the systemic group on Day 15 (p=0.007 and p=0.032). Immunohistochemical analyses showed that galectin-3 values exhibited a significant difference in all groups on Day 30 (p=0.020). In all groups, it was determined that type I collagen values showed an increasing trend on Day 30, compared to the values on Day 15, whereas type III collagen values showed a decreasing trend. Conclusion: Our results demonstrated that local and systemic use of TXA does not impair tendon healing. Although advanced studies are needed, our study suggests that TXA application reduces the development of fibrosis.Öğe HOW USEFUL IS ELASTOGRAPHY IN THE FOLLOW-UP OF ACHILLES TENDON REPAIR?(Sociedade Brasileira de Ortopedia e Traumatologia, 2022) Çetin, Mehmet Ümit; Sökmen, Bedriye Koyuncu; Fidan, Fırat; Mutlu, Harun; Sarı, Abdülkadir; Dinçel, Yaşar Mahsut; Kazdal, C.Introduction: In addition to conservative modalities in the treatment of Achilles tendon injuries, open, percutaneous and minimally invasive semi-open techniques, as well as biological open surgical repair methods are used as surgical options. Compression elastography is one of the methods used for the follow-up of treatment in Achilles tendon injuries. Methods: 23 patients were included in our study between July 2013 and June 2014, as long as they had at least 4 years of follow-up. In the final control, the intact side and the operated side were both examined and compared. The variables were the American Orthopedic Foot and Ankle Score (AOFAS) which is measured as a functional score considering plantar flexion and dorsiflexion; calf circumference; Achilles tendon anteroposterior (AP) diameter; and elastographic examination. Results: The strain ratio value and AP diameter of the patients was significantly higher on the operated side than on the non-operated side (p <0.001). There was no significant difference between the plantar flexion and dorsiflexion degrees on the operated side of the patients (p> 0.05). No correlation was observed between strain ratio and AOFAS (p: 0,995). Conclusion: Elastography is not a useful technique to evaluate functional results on long-term tendon healing.

In this study, we evaluated whether there was a statistically significant difference between the results of patients whounderwent cyclic exercise by way of physical examinations, knee joint stability tests, and functional evaluation tests, comparedwith the patients who underwent ACL reconstructions with or without cyclic exercise.Methods: Between March 2016 and May 2018, 59 patients with at least eight months’ follow-up of an ACL reconstruction wereidentified. Thirty patients (Group 1) who underwent cyclic exercise before tibial fixation and 29 patients (Group 2) who did notundergo cyclic exercise were evaluated and compared.Results: The mean age of the patients in Group 1 and Group 2 was 25.9 (range, 18-36) years and 25.2 (range, 18-35) years, respectively. The mean follow-up period in Group 1 was 14.6 (range, 8-22) months and 13.5 months in Group 2 (range, 8-21 months).The mean Lysholm scores of Group 1 and 2 were 95.1 (range, 83-100) and 87.1 (range, 78-100), respectively. The modified Cincinnati scores of Groups 1 and 2 were 28.7 (range, 24-30) and 26.2 (range, 21-30). The mean IKDC subjective knee evaluation scoresin Groups 1 and 2 were 91.9 (range, 83-100) and 86.7 (range, 75-100). The mean thigh atrophy was 1.5 cm in Group 1 and 2.5 cm inGroup 2. In Group 1, 23 patients jumped 85% of the distance compared with the intact side in the single-legged hop test, and 12patients in Group 2 were able to hop this distance successfully.Group 1 had statistically significantly better results in Lysholm activity scores, modified Cincinnati scores, IKDC subjective kneeassessment scores, two-time IKDC activity scale results, comparison of thigh diameters, and single-legged hop tests (p<0.05). Nosignificant difference was found in other examinations and tests.Conclusion: Cyclic exercise during the operation had a positive effect on functional scores. We believe that cyclic exercise shouldbe added to the operative procedureÖğe Morphometric risk factors effects on anterior cruciate ligament injury(Turkish Joint Diseases Foundation, 2023) Gültekin Muhammet Zeki; Dinçel, Yaşar Mahsut; Keskin, Zeynep; Arslan, Serdar; Yıldırım, AhmetObjectives: This study aims to compare the morphometric differences between patients with and without an anterior cruciate ligament (ACL) injury and to investigate the anatomical risk factors associated with ACL injury. Patients and methods: Between February 2020 and February 2022, a total of 100 patients (57 males, 43 females; mean age: 36.2 +/- 6.8 years; range, 18 to 45 years) who were operated for isolated non-contact ACL tear as the patient group and a total of 100 healthy individuals (58 males, 42 females; mean age: 35.0 +/- 6.9 years; range, 18 to 45 years) without an ACL tear as the control group were included. Magnetic resonance imaging scans of the knee joint were included in the study. Morphological variables of the ACL, distal femur, proximal tibia, and menisci were measured. Results: The mean ACL inclination angle and medial meniscus bone angle were 37.7 +/- 3.8 and 20.2 +/- 2.9 in the patient group and 48.1 +/- 3.3 and 25.0 +/- 2.9 in the control group. According to the results of multivariate analysis, those with small ACL inclination angle and medial meniscus bone angle were more likely to have ACL tear (odds ratio: 0.128, intraclass correlation coefficient: 0.038-0.430, p= 0.001). Conclusion: Small ACL inclination angle and medial meniscus bone angle can be a risk factor for ACL tear.Öğe The Change of Oral Presentations of National Anatomy Congresses Over the Years(2023) Özkan, Mazhar; Dinçel, Yaşar MahsutIntroduction: In this study, it is aimed to examine the characteristics and publication rates of oral presentations presented in national congresses. Methods: The data about the oral presentations in national anatomy congresses (from 2016 to 2021), including the number of contributing institutions, the institutions that contributed the most oral presentations each year, and the publication rates of the oral presentations in the journals scanned in different indexes. In the study, the titles and the keywords were scanned using Google Scholar and Web of Science, and journal index details were noted. Results: Of the national congresses we examined in our study, the most oral presentations (193) were the congress in 2019 and the least oral presentations (47) were the congress in 2017. The publication rate of oral presentations was highest in the papers of the congress in 2016 (42%) and at least in the papers of the congress in 2019 (13%). None of the oral presentations in the last congress held in 2021 were published until the time of our study. Large proportions (34%) of the papers that are accepted as oral presen tations and published are radiological studies. 70% of the publications were published in journals indexed in Web of Science. Conclusion: For both new and senior academics, congresses offer a useful and distinctive setting. Congress papers showcase the scientific opportunities and interests of various universities while also providing opportunities for collaboration. Attendance at a conference is significantly influenced by its location, timing, and financial situation.Öğe The Effect of Tranexamic Acid and Tourniquet Use on Tibial Cement Penetration in Primary Total Knee Arthroplasties(Elsevier Inc, 2020) Dinçel, Yaşar Mahsut; Sarı, Abdulkadir; Çetin, Mehmet Ümit; Günaydın, Burak; Ağca, E.; Doğan, A.H.; Varol, R.Background: In this study, our aim was to compare the effects of tourniquet and tranexamic acid (TXA) use on tibial cement penetration in primary total knee arthroplasty (TKA) using radiograph images. In addition, we also aimed at investigating the effects of age, gender, body mass index (BMI), and bone mineral density on cement penetration. Methods: One hundred seventy patients who underwent TKA for primary osteoarthritis were retrospectively evaluated. TXA was administered to patients in group 1 (n = 96), and tourniquet application was used in patients in group 2 (n = 74). Tibial cement penetration was evaluated radiologically on a total of 4 zones: 2 anteroposterior and 2 lateral zones. In addition, age, gender, BMI, and bone mineral density were recorded in each group. Results: The mean cement penetration in the total study population was 2.34 ± 0.24 mm, with a mean of 2.33 ± 0.25 mm in the TXA group and a mean of 2.35 ± 0.24 mm in the tourniquet group (P = .453). A negative correlation was detected between BMI and anteroposterior 1 values in the total and TXA groups (P = .022 and P = .029). In the evaluation of the differences between genders, significantly higher penetration values were observed only in the females in the tourniquet group (P = .024). Conclusions: The use of TXA instead of a tourniquet does not reduce the depth of cement penetration in TKA. The clinical implications of individual-induced penetration differences may be significant for future implant survival. © 2020 The AuthorsÖğe Tranexamic acid in knee arthroplasty: the effect of preoperative intravenous administration of together with postoperative intravenous maintenance and periarticular administration on bleeding, transfusion, and hospitalization time – a retrospective cohort study(2022) Dinçel, Yaşar Mahsut; Başılgan, Seçkin; Polat, Abdulkadir; Özbey Büyükkuşçu, Mehmet; Yağmurlu, Mehmet FıratObjective: To compare patients who received preoperative intravenous (IV) plus postoperative maintenance IV tranexamic acid (TXA) therapy and perioperative periarticular TXA to those who did not receive TXA during total knee arthroplasty (TKA) in terms of blood loss, transfusion requirements, and length of hospital stay. Material and Method: Data from 194 patients who underwent TKA between 2016 and 2019 were reviewed. A total of 106 patients were included. Twenty-one patients were male, and 95 were female. The patients were divided into three groups: Group 1 (n=37) that did not receive perioperative TXA, Group 2 (n=35) that received preoperative IV and postoperative maintenance TXA therapy, and Group 3 (n=34) that received preoperative IV and perioperative periarticular TXA. The groups were similar regarding demographic data. Statistical comparisons between the groups were made concerning the decrease in hemoglobin levels on postoperative days 1 and 3, the need for transfusion, and the length of hospital stay. Results: The mean decrease in hemoglobin on the postoperative first and third days were 1.69(±1.13) and 2.94(±1.14)g/ dl, in Group 1, 1.41(±0.99) and 2.44(±1.28)g/dl, in Group 2, and 1.24(±0.83) and 2.21(±0.84)g/dl in Group 3 respectively. The statistical comparison of the hemoglobin decrease revealed a significant difference between Groups 1 and 3 on the postoperative first day(p<0.05). There was no other significant difference between the remaining group pairs. There was a statistically significant difference in the length of hospital stay and the amount of erythrocyte suspension used between Groups 1 and other groups (p<0.05). In Group 1, prolonged wound discharge was observed in four patients. No additional surgical intervention was performed in any of the three groups due to infection, and no vascular thrombosis or embolism was observed. Conclusion: Our results showed that IV and periarticular TXA applications in TKA effectively reduced bleeding and bleeding- related complications without causing additional complications.Öğe Tuberculosis osteomyelitis of the tibia mimicking Brodie abscess: A case report and review of the literature(Sage Publications Inc, 2019) Sarı, Abdulkadir; Dinçel, Yaşar Mahsut; Erdoğdu, İbrahim Halil; Sayıner, Hakan Sezgin; Ağır, İsmail; Çetin, Mehmet ÜmitBackground: Tuberculosis osteomyelitis is rarely seen in the diaphyseal bones. It may be confused with Brodie's abscess due to similar clinical, radiological and laboratory findings. Late diagnosis of the disease causes bone destruction. Tuberculosis osteomyelitis of the bone is a rare condition caused by the Mycobacterium tuberculosis. Its incidence has increased in Western countries in recent years due to HIV infection, increasing elderly population and emerging resistant strains. The slow progress of tuberculous osteomyelitis, due to lack of significant elevations in the laboratory values and changes in the radiographic appearance, often leads to confusion with the subtypes of subacute osteomyelitis, defined as Brodie's abscess. These two low-virulence clinical cases often lead to delays in diagnosis and progressive bone destruction. Case presentation: We report a 65-year-old male patient who presented to our clinic with pain, swelling and sensitivity in the left leg. Diagnosed with infection in the tibia, the patient had undergone antibiotherapy. However, the patient's symptoms were not resolved and we performed bone curettage and cementation. M. tuberculosis-specific DNA was detected by real-time polymerase chain reaction and the M. tuberculosis complex was produced from the perioperative samples. Conclusion: In conclusion, histopathological examination and polymerase chain reaction are essential before surgery of subacute and chronic osteomyelitis with atypical clinical, laboratory and radiological findings for early diagnosis and accurate treatment.
