Overview
Brief Summary
Anterior cruciate ligament (ACL) rupture is one of the most common injuries in sports medicine. ACL reconstructions are usually performed to restore the stability of knee joint and prevent the secondary meniscal and chondral lesions.
120 Subjects with ACL injury were randomly assigned to two groups for ACL reconstruction.Group one: tibial fixation with PEEK Interference Screws (Rejoin Hangzhou Martins Medical Equipment Co., Ltd.);Group two: tibial fixation with Biosure PK interference screw (Smith & Nephew plc). The subjects will be followed by 12 months after surgery for evaluations.Outcome measures included Lysholm score,IKDC, ADT,Lachman.
