    Anterior Cruciate Ligament Reconstruction Improves Functional Scores and Quality of Life in Patients Older Than 50 Years of Age
    (Elsevier Inc., 2023) Çokyasar, B.; Altun, O.; Dasar, U.
    Purpose: To evaluate quality of life changes and functional outcomes of anterior cruciate ligament reconstruction in patients older than 50 years of age with anterior cruciate ligament injury. Methods: Patients who were older than 50 years of age and had undergone anterior cruciate ligament reconstruction with single-bundle hamstring tendon auto graft surgery between January 2016 and February 2018 were identified. Preoperative Tegner activity scores, Lysholm knee scores, International Knee Documentation Committee (IKDC) 2000 scores, and Short-Form 36 scores were compared with results that were documented 1 year after surgery. Results: A total of 35 patients were included (20 male/15 female; mean age 52 years [range 50-59 years]). Patients’ preoperative mean Tegner score was 1.48. Mean Tegner score at 1-year follow-up was 3.82. Preoperative mean Lysholm score was 45.8. Postoperative mean Lysholm score was 88. Preoperative mean IKDC 2000 score was 33. Postoperative mean IKDC 2000 score was 82. All of these changes were statistically significant (P < .05). All of the parameter changes at Short Form-36 except for role limitations due to emotional problems were statistically significant. Conclusions: Improved functional knee scores, quality of life, and psychological status were achieved at anterior cruciate ligament reconstruction in patients older than 50 years of age. Level of Evidence: Level IV, therapeutic case series. © 2023 The Authors

    The combined use of oral and topical tranexamic acid is a safe, efficient and low-cost method in reducing blood loss and transfusion rates in total knee arthroplasty
    (SAGE Publications Ltd, 2017) Cankaya, D.; Dasar, U.; Satilmis, A.B.; Basaran, S.H.; Akkaya, M.; Bozkurt, M.
    Aims: The combined (IV (intravenous) + topical) use of tranexamic acid (TXA) has been shown to be a safe method and more effective than single (IV or topical) application. The optimal administration method of TXA is still being investigated and safety, efficiency and cost are the three main crucial parameters in achieving the best administration method. We aimed to determine whether combined (oral + topical) use of TXA reduced blood loss and transfusion rates more than single (topical) administration in TKA and whether oral + topical use is as safe and efficient as the IV + topical use, in addition to the main advantage of relatively low cost. Methods: In this prospective, randomized study, 100 patients were randomly assigned to either the topical TXA group or the combined (oral + topical) TXA group. There were no significant differences between the groups in age, body mass index or gender. The haemoglobin and haematocrit levels of each patient were recorded preoperatively and on post-operative days 0, 1, 2 and 3. The post-operative suction drainage and blood transfusion volumes were also recorded. Results: There were statistically significant differences between the groups in haemoglobin and haematocrit levels on post-operative days 0, 1, 2 and 3 (p < 0.05) in favour of the combined group. The post-operative drainage amounts (p = 0.0001), measured blood loss volume (p = 0.003) and transfusion rates (p = 0.03) were lower in the combined (oral + topical) group compared to the topical group. Conclusions: Of the different methods of TXA administration, the combined use of oral and topical TXA is a safe, efficient and low-cost method in reducing blood loss and transfusion rates after TKA. © Journal of Orthopaedic Surgery 2017.

    Evaluation of the anterolateral ligament of the knee by magnetic resonance imaging in patients with chronic anterior cruciate ligament rupture
    (Elsevier B.V., 2019) Duran, S.; Gunaydin, E.; Aksahin, E.; Dasar, U.; Bicimoglu, A.; Sakman, B.
    Objective: The purpose of this study was to evaluate the visibility of the anterolateral ligament (ALL) by magnetic resonance imaging (MRI) in patients with chronic anterior cruciate ligament (ACL) rupture. Materials and methods: This retrospective case – control study compared 1.5 - T MRI scans for 50 patients with a chronic ACL rupture with those of a control group of 50 patients with an intact ACL. The ALL was evaluated in three portions: femoral, meniscal, and tibial. The status of each portion was classified as visualized or non-visualized. Two radiologists separately reviewed all the MRI scans to evaluate interobserver reliability. Results: At least one portion of the ALL was visualized in 100% of the control group and 72% of the chronic ACL rupture group. All three portions of the ALL were identified in 72% of the control group but only 10% of the chronic ACL rupture group. In both groups, the most commonly visualized portion was the meniscal portion and the least visualized was the tibial portion. In 18% of the chronic ACL rupture group, no portion of the ALL was visualized. Conclusions: The visibility of the ALL of the knee was significantly lower in patients with a chronic ACL rupture than in those with an intact one. © 2019 Delhi Orthopedic Association
