Arthroscopic reconstruction of the posterior cruciate ligament with double-bundle hamstring tendons via double-tunnel in femoral / 中华骨科杂志

ABSTRACT

Objective To research the surgical technique and curative effect of the posterior cruciate ligament(PCL) anatomical reconstruction with double-bundle hamstring tendons absorbable interference screw fixation via double-tunnel in femoral under arthroscopy. Methods 24 patients, average age of 32 years ranged from 17 to 42 years old, were treated with anatomical reconstruction of PCL through double-tunnel in femoral and one tunnel in tibia with double-bundle hamstring tendons fixed with absorbable interference screw under arthroscopic. The anterolateral bundle was reconstructed with multistranded autograft semitendinosus tendon grafts and was tightend and fixed, at knee flexion 15?-30?. The posteromedial bundle was reconstructed with multistranded autograft gracilis tendon grafts, and was tightened and fixed, at knee flexion 60?-70?. Results All the patients were followed up for a mean time of 9.4 months (6 months-19 months). All the knee joint motion were in normal range, no exhibition of pain and distinct trauma arthritis. The postoperative posterior drawer test, reverse Lachman test, tibia sags sign and reverse pivot shift test were all negative. The postoperative Lysholm score was (92.7?6.4) points, and the postoperative score increased significantly compared with the preoperative (t=3.12, P
