ABSTRACT

[Objective] To study the effect of arthroscopic reconstruction of anterior cruciate ligament using RIGIDfix and Intraflx system with quadruple-strand hamstring tendons.[Method]Thirty-six cases of anterior cruciate ligament ruptures were reconstructed arthroscopically with four strands of hamstring tendons,and the grafts were fixed with RIGIDfix and Intrafix system.Ptients were treated with systematic rehabilitation therapy and relevant complications were managed post-operatively.The patients were followed up for 6~12 months,ask the patients' subjective symptom,examine the knee range of motion,anterior drawer test,Lachman test and Pivot shift test,were managed to evaluate clinical result according to Lysholm rating.[Result]All patients had no serious complication,and were followed up for 6~12 months post-operatively.All patients had returned his post,knee range of flexion achieved 130?,extention achieved 0?.Three cases sometimes felt his knee soft and instabilization during exercise violently,the other patients had no sensation of soft and instabilization.When patients were followed up,anterior drawer testnegative 35 cases,positive 1 case;Lachman testnegative 33 cases,positive 3 cases;Pivot shift test of all patients were negative.The Lysholm score increased from 51.3?4.2 to 85.6?4.6,the difference was significant(P
