BACKGROUND: Although successful at restoring near normal laxity to the knee in the short term, anterior cruciate ligament reconstructions have not been shown to prevent the development of posttraumatic arthritis. HYPOTHESIS: Bone bruises and articular cartilage injuries sustained at the time of initial injury (1991) would not resolve. Our secondary hypothesis was that the presence of a bone bruise or articular cartilage injury originally identified on magnetic resonance imaging would not be associated with long-term outcomes after anterior cruciate ligament reconstruction evaluated by the International Knee Documentation Committee questionnaire. STUDY DESIGN: Cohort study (prognosis); Level of evidence, 1. METHODS: We attempted to contact all patients from an original cohort (N = 54) for follow-up evaluation, which included repeat radiographs, magnetic resonance images, physical examination, and International Knee Documentation Committee questionnaire more than a decade postoperatively. RESULTS: Forty-four patients (82% of the original cohort) returned for on-site follow-up. No patient with a bone bruise identified on original magnetic resonance imaging had one identified at 12-year follow-up. The mean ( +/- SD) International Knee Documentation Committee score at follow-up with no bone bruise originally present was 70.6 ( +/- 12.7) versus 70.0 ( +/- 8.1) when a bone bruise was observed (P > .05). No consistent association was observed between the presence of an initial articular cartilage lesion with a lesion on follow-up magnetic resonance images. The mean ( +/- SD) International Knee Documentation Committee score at follow-up with no articular cartilage injury was 69.0 ( +/- 11.9) versus 72.8 ( +/- 12.0) with articular cartilage lesion (P > .05). CONCLUSION: All bone bruises identified in our study with magnetic resonance imaging at the time of initial injury had resolved at 12-year follow-up. The presence of a bone bruise at the time of initial injury did not significantly alter the patient-oriented outcome by International Knee Documentation Committee after anterior cruciate ligament reconstruction. Additionally, articular cartilage abnormality on magnetic resonance imaging did not influence the International Knee Documentation Committee score.
