Abstract

This study analyzes differences in knee function in ACL deficient knees with different meniscus status. Eighty patients, 12 women and 68 men, were matched in four groups according to sex, age, knee injuries, and followup time. Group I had two intact menisci; Group II, one meniscus successfully repaired; Group III, one meniuscus removed; and Group IV, both menisci removed. The ACL was repaired acutely or reconstructed later in most cases and other significant ligament injuries were treated. All patients were reexamined clinically 6 to 8 years after injury. Knee function was recorded using the Lysholm knee function score. Activity level before injury and at followup was rated with the Tegner scale. Stability was tested and weightbearing roentgenograms were taken. There was a higher frequency of ACL reconstructions in Groups I and II, but instability was the same in all groups. There were no differences in the frequency of osteoarthritis among the first three groups, but Group IV had a higher incidence of osteoarthritic changes. Osteoarthritis did not result in lower knee function, poorer subjective evaluation, or increased impairment of motion. Verf.-Referat (gekuerzt)
