Abstract:
Objective To study the clinical outcome of arthroscopic reconstruction of posterior cruciate ligament (PCL) with hamstring tendons and mini-plate and button. Methods From January 1998 to December 2000, 21 cases of PCL ruptures were reconstructed arthroscopically with five to seven strands of hamstring tendons and mini-plate and button. There were 14 males and 7 females aging from 27 to 49 years with the mean age of 36.4 years. All of the patients were free from posterolateral corner ligament injury. The interval from injury to diagnosis was 2.5 months ranging from 2 weeks to 15 months. There were 3 fresh and 18 old injuries. The patients were followed up for more than 12 months and were evaluated for knee function. Results No extension limitation occurred and the flexion degree were more than 120? in all cases 3 months postoperatively. One year after operation, the quadriceps-hamstrings peak torque ratio reached more than 90% of the uninjured leg; posterior drawer test at 70? flexion were negative in all but two cases who had one-degree instability; posterior drawer test at 30? flexion were one degree positive in six cases, and negative in other cases; the Lysholm knee score were 90.7?2.3. Conclusion Arthroscopic reconstruction of PCL with hamstring tendons and mini-plate and button is relatively simple and reliable for the restoration of knee function.
