Abstract
OBJECTIVE: To discuss the effectiveness of posterior cruciate ligament (PCL) reconstruction with autologous peroneus longus tendon under arthroscopy. METHODS: Between January 2016 and December 2018, 46 patients with PCL injuries were enrolled. There were 34 males and 12 females, with an average age of 40.7 years (range, 20-58 years). There were 43 cases of acute injury and 3 cases of old injury. The anterior drawer test and the posterior tibia sign were positive in 4 cases, the posterior drawer tests and the posterior tibia sign were positive in 46 cases, the varus stress tests were positive in 10 cases, and the valgus stress tests were positive in 6 cases. The difference of dial-test at 30° knee flexion between affected and healthy sides was (5.20±3.91)°. The tibia posterior displacement under posterior stress position was (12.03±2.38) mm. The Lysholm score of the knee joint was 36.68±7.89, the International Knee Documentation Committee (IKDC) score was 33.58±5.97, and the American Orthopaedic Foot and Ankle Association (AOFAS) score of the ankle joint was 97.60±1.85. PCL was reconstructed with autologous peroneus longus tendon under arthroscopy, and the combined meniscus injury, posterolateral complex injury, and anterior cruciate ligament injury were all treated according to the degree of injury. RESULTS: All incisions healed by first intention. Forty patients were followed up 12-26 months, with an average of 16.0 months. At last follow-up, the Lysholm score of the knee joint was 84.85±7.03, and the IKDC score was 87.13±6.27, which were significant different from preoperative ones ( t=-13.45, P=0.00; t= -39.12, P=0.00); the AOFAS score of ankle joint was 93.98±2.14, which was not significant different from preoperative one ( t=8.09, P=0.90). The tibia posterior displacement under posterior stress position was (2.75±1.76) mm and the difference of dial-test at 30° knee flexion between affected and healthy sides was (1.75±2.09)°, which were significant different from preoperative ones ( t=29.00, P=0.00; t=4.96, P=0.00). The posterior drawer test and the posterior tibia sign were positive in 1 case and negative in 39 cases; the anterior drawer test and the varus and valgus stress tests were all negative. CONCLUSION: Reconstruction of PCL with autologous peroneus longus tendon under arthroscopy can significantly improve the stability and function of the knee joint, with satisfactory clinical results.
