인조인대를 이용한 슬관절 외측 및 후외측 불안정성 동시 보강수술

Abstract

The purpose of this study was to evaluate the clinical prognosis of post-operative lateral and posterolateral instability of the knee with artificial ligament. The assessment was made with 13 cases who underwent augmentation of lateral collateral ligament (LCL) and popliteal tenodesis with artificial ligament (synthetic polyester, ABC ligament, Surgicraft

UK) at this Medical Center during the period from April 1997 to May 2003 and whose followup period was longer than one year. We analysed and recorded the physical findings (external rotation recurvatum test and posterolateral drawer test), stress roentgenograms (preoperative and postoperative) and Lysholm score. According to the clinical tests and stress roentgenograms, the lateral and posterolateral instability of the knee were postoperatively improved in 12 cases (92%). Average Lysholm score was 50.5 preoperatively and 89 postoperatively. Our study found that the surgery of lateral and posterolateral instability of the with augmentation of LCL and popliteal tenodesis with artificial ligament is a simple technique. Taking these results into consideration, it seems to be one of the effective treatment methods.
