We evaluated 58 @entity1 (mean age 30.4 years) who had undergone an isolated anterior cruciate ligament (ACL) reconstruction for chronic instability (mean time from injury to surgery, 8.2 +/- 5.2 years) and showed radiographic evidence of degenerative @entity4040 . Objective evaluation at a mean of 4.1 years postoperatively included KT-1000 arthrometer stability, range of motion, and quadriceps muscle strength testing. Subjective analysis at a mean of 5.5 years postoperatively included rating of @entity158 , stability, activity level, and a total score both preoperative and postoperative. @entity1 were divided into two groups: group 1 (n = 28) with a follow-up < or = 5 years (mean 3.3 years); group 2 (n = 30) with a follow-up > 5 years (mean 7.2 years). Results were analyzed by length of follow-up and by the grade and compartment of @entity4040 . All @entity1 enjoyed a full range of motion preoperatively and postoperatively. The mean KT-1000 arthrometer manual maximum difference improved from a mean of 8.2 mm preoperatively to 2.4 mm postoperatively. All subjective scores showed statistically significant improvement over the preoperative values. @entity1 with medial compartment @entity4040 reported a better subjective total score (mean 87) than @entity1 with lateral compartment (mean 73) or bicompartmental (mean 79) @entity4040 , but there was not a statistically significant difference. There was no correlation between @entity158 , stability, or total scores and time after surgery. @entity1 in groups 1 and 2 had equal objective stability and similar subjective scores, but group 2 reported a lower activity level. An isolated ACL reconstruction can provide long-term stability and symptomatic @entity158 relief in @entity1 with chronic instability and @entity4040 . The procedure has low morbidity and does not compromise future tibial osteotomy or total knee replacement.
