Exclusion criteria included meniscus transplantation, realignment osteotomy, or other ligamentous injury. Complications, reoperations, and patient responses to validated outcome measures were reviewed. Failure was defined by any procedure involving allograft removal\/revision or conversion to arthroplasty. Kaplan\u2010Meier analysis and multivariate Cox regression were performed to evaluate the association of ACL reconstruction (ACLR) with failure.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      A total of 50 ACL\u2010intact and 25 ACL\u2010reconstructed (18 prior, 7 concomitant) OCA patients were analyzed. The mean age was 36.2\u00a0years (range, 14\u201062\u00a0years). Mean follow\u2010up was 3.9\u00a0years (range, 2\u201014\u00a0years). Patient demographics and chondral lesion characteristics were similar between groups. ACL\u2010reconstructed patients averaged 2.2 \u00b1 1.9 prior surgeries on the ipsilateral knee compared with 1.4 \u00b1 1.4 surgeries for ACL\u2010intact patients (\n                      <jats:italic>P<\/jats:italic>\n                      \u00a0= .014). Grafts used for the last ACLR included bone\u2010patellar tendon\u2010bone autograft, hamstring autograft, Achilles tendon allograft, and tibialis allograft (data available for only 11 of 25 patients). At final follow\u2010up, 22% of ACL\u2010intact and 32% of ACL\u2010reconstructed patients had undergone reoperation. OCA survivorship was 90% and 96% at 2\u00a0years and 79% and 85% at 5\u00a0years in ACL\u2010intact and ACL\u2010reconstructed patients, respectively (\n                      <jats:italic>P<\/jats:italic>\n                      \u00a0= .774).
