title: Anterior instability of the knee despite an intensive rehabilitation program.
abstract: To investigate if an intensive rehabilitation program has a positive influence on the late course of an old, isolated anterior cruciate ligament rupture, patients were evaluated at an average of 8 years after injury. Seventy-five percent had acquired the injury during sporting activities. After diagnostic arthroscopy, which was done at an average of 163 days after the injury, the patients immediately were assigned to an intensive rehabilitation program. At the followup examination, none of the patients had an excellent result as determined by the Swiss Knee Group Score; 6 patients had a good result; 13 had a fair result; and 8 had a bad result. Fourteen patients had a partial meniscectomy during the followup period, and 4 had positive signs for meniscal lesions at the followup examination. In 52% of the patients gonarthrosis had advanced 2 stages, and in 26% it had advanced 3 stages. There was a significant correlation between worsening of gonarthrosis and previous meniscectomy, poor evaluation scores, and clinical signs of instability. Even an intensive rehabilitation program cannot prevent secondary lesions of the meniscus with ensuing joint degeneration. Thus, immediate operative reconstruction of old ruptured anterior cruciate ligaments is recommended.
