Abstract

Purpose: The purpose of this study was to make a report on the clinical prognosis of post traumatic lateral and posterolateral instability of the knee after LCL augmentation and popliteal tenodesis. Materials and Methods: The assessment was made among 21 cases who underwent augmentation of lateral collateral ligament(LCL) and popliteal tenodesis with allograft or artificial ligament (synthetic polyester, ABC ligament, Surgicraft, U.K.) at this Medical Center during the period from July 1996 to July 2003 and whose follow-up period was longer than one year. The authors recorded and analysed the physical findings (external rotation recurvatum test & posterolateral drawer test), stress roentgenograms(preoperative and postoperative) and Lysholm score. Results: The lateral and posterolateral instability of the knee were improved in 20 cases postoperatively, acccording to the clinical test and stress roentgenograms . Average Lysholm score was 52.5 preoperatively and 86.7 postoperatively .Conclusion: Our study found the surgery of lateral and posterolateral instability of the knee with augmentation of LCL and popliteal tenodesis using allograft or artiflcial ligament is simple technique. Taking these results into consideration, it seems to be one of effective methods of treatment.
