Abstract:
Objective To investigate the clinical efficacy of arthroscopy with anchor treatment on acute patellar dislo?cation. Methods Retrospective analysis of patient with acute patellar dislocation cases who visited our hospital from March 2010 to June 2013 and were followed up for 10 months or more after being discharged. Patients all underwent physical exami?nation and imaging examination before operations. All operations were performed under arthroscopy. Joint hematoma were first drained, then articular cartilage injury were explored and repaired. Corresponding relationship between patella and femo?ral condyle were observed. After that, lateral retinaculum was released and medial patellofemoral ligament was repaired by suture anchors. Finally patellar reduction and its corresponding relationship with femur were observed after operation. Re?sults Medial patella cartilage injury and bone contusion of femoral condyle were all observed under arthroscopy. Medial patellofemoral ligament damage and tensed lateral patellar retinaculum were combined. By the time of follow-up at 10~18 months later, no dislocation was found and fear test are all positive. No recurrence of patellar dislocation was observed. Compared the conditions before operation and the last follow-up, Lysholm score(91.38±1.65 vs 60.04±3.93), Kujala score (90.62±2.08 vs 55.27±3.00),patellar camber angle(11.96°±1.43° vs 25.15°±2.13°)were all imporved(P<0.01). Conclu?sion Arthroscopy with suture anchors present good clinical effect in the treatment of acute patellar dislocation, which in?cludes alleviating keen pain, stabilizing joint instability and restoring knee stretching. It also present with less recurrence of patellar dislocation.
