Abstract des Autors

Few natural history studies exist of patients with isolated posterior cruciate ligament (PCL) injuries. This report reviews a study of 133 patients followed prospectively for a mean of 5.4 years from the time of their PCL injury. The mean subjective score was 84 of 100 points and the scores were not statistically different for different grades of PCL laxity. The injured PCL usually healed with some laxity, but the laxity did not increase with time from injury. There was a trend toward medial joint arthrosis, but it was not related to the grade of PCL laxity. Regardless of PCL laxity, 1/2 of patients returned to the same sport at the same level, 1/3 returned to the same sport but at a lower level, and 1/6 could not return to the same sport. The results of this study can be used as a baseline for evaluating surgical treatment methods. Verf.-Referat
