    The triangle between the anterior and posterior cruciate ligaments: an arthroscopic anatomy study
    (TURKISH ASSOC ORTHOPAEDICS TRAUMATOLOGY, 2015-01-01) Kaya, Alper; Koken, Murat; Akan, Burak; Karaguven, Doga; Guclu, Berk
    Objective: The goal of anterior cruciate ligament (ACL) reconstruction is to place the graft in closest proximity to the native ACL anatomy. This study aims to examine the angular relation between intact anterior and posterior cruciate ligaments (PCL) from an arthroscopic perspective. Methods: Forty patients (20 male, 20 female) with a mean age of 35.12 (range: 18-40) years that underwent knee arthroscopy for reasons other than ACL rupture were included in the study. Following diagnostic examination and repair of the primary pathology, the triangle between ACL and PCL was seen at different flexion degrees of the knee joint (120, 90, 60, and 30 degrees) through standard anterolateral (AL) and anteromedial (AM) portals. The narrow top angle of the triangle between the long intersecting axes of ACL and PCL was measured using recorded images by 3 blind observers. Results: The average ACL-PCL angle was 61 degrees, (standard deviation +/- 2 degrees) at 90 degrees of knee flexion. The angles were narrower when viewed through the AM portal. The degree of the angles was not affected by age, sex, body mass index (BMI), or the side (right or left) on which the procedure was performed. There was good-to-excellent intra-and interobserver reliability. Conclusion: The angular relation between intact ACL and PCL has the potential to provide a better view of the anatomy during arthroscopic ACL surgery. To perform better anatomic reconstructions, it is important to create a 60 degrees angle between the ACL graft and PCL (as viewed through AL portal) at 90 degrees of knee flexion.

    Comparison of Third Generation Proximal Femoral Nails in Treatment of Reverse Oblique Intertrochanteric Fractures
    (BEZMIALEM VAKIF UNIV, 2019-01-01) Ulku, Tekin Kerem; Tok, Okan; Seyhan, Mustafa; Gereli, Arel; Kaya, Alper
    Objective: The purpose of the study is to evaluate the treatment results of reverse oblique AO/OTA 31A1 fractures that have highly mechanical instability risk with two third generation intramedullary nails. Methods: Twenty-eight patients (8 men, 20 women) treated by third generation proximal femoral nails {[}proximal femoral anti-rotation (PFNA)(R) or Intertan (R)] followed minimum one year were included. Average age was 65.0 (31-93) years. Clinical and radiological results, screw migration at one year and complications were recorded. Results: Mean operation time was 72.2 and 72.5 minutes, flouroscopy time was 64.4 and 64.7 seconds, mobilisation time was 2.1 and 2.2 days, full weight bearing time was 8.6 and 8.5 weeks, tip-apex distance was 20.1 and 20.2 mm, fracture healing time was 10.5 and 10.2 weeks, Harris hip score at one year was 80.5 and 83.5, neck-shaft angle difference at one year was 1.6 and 1.1 mm, screw migration at one year was found in 10 and 3 patients and mean migration distance was 3.1 and 0.4 mm for PFNA and Intertan nails respectively. No complications recorded that needs secondary intervention. Fracture healing obtained in all patients. Conclusion: Reverse oblique intertrochanteric fractures can be effectively treated with third generation intramedullary nails. More screw migration was seen in PFNA than Intertan nails after the operation in this study.
