Abstract:
Objective To describe the surgical technique of arthroscopic reconstruction of anterior cruciate ligament with quadrupled stranded semitendinosus tendon and suture plate, and to review the short term outcome of its clinical application. Methods Fifty one cases of chronic anterior cruciate ligament ruptures were reconstructed arthroscopically with quadrupled stranded semitendinosus tendon. During the operation the harvested semitendinosus tendon was cut into two segments of equal length, and then folded to four strands. The proximal end of the graft was fixed to a small plate that lied over the orifice of the femoral tunnel, and the distal end was fixed to a button that covered the orifice of the tibial tunnel. The patients were followed up for 12-24 months and were rehabilitated according to a special plan. The range of motion and stability of the knee, the muscle function of the thigh, the knee function in daily activities, and the ability for running were evaluated periodically. The influence of the combined meniscal and cartilage lesion on the restoration of knee function was also studied. Results The ranges of motion of the injured knee were regained in all cases three months after operation. The quadriceps/hamstrings peak torque ratio reached more than 90% of the uninjured leg two years after operation. The results of KT-1000 examination showed that the anterior stability of the knee after anterior cruciate ligament reconstruction decreased slightly with time, but in 73.8 percent of all cases the anterior stability of the injured knee were equal or better than the uninjured knee. According to Lysholm knee scale score, the average knee score were 56.7?7.4 and 98.5?0.3 respectively before and two years after operation, and the difference was of statistical significance. The average knee score of the group with cartilage lesion was 96.44?2.36, and that without cartilage lesion was 99.47?0.24 two years after operation. The data showed a significant statistical difference between the two groups. The accelerating and decelerating running ability were regained in all cases without limping one year after operation. Conclusion Arthroscopic reconstruction of anterior cruciate ligament with quadrupled stranded semitendinosus tendon and suture plate is a reliable way to restore the knee function. The combined cartilage lesion has an obvious influence on the knee function.
