Association of Meniscal Status, Lower Extremity Alignment, and Body Mass Index With Chondrosis at Revision Anterior Cruciate Ligament Reconstruction

Outcomes are known to be less favorable in revision anterior cruciate ligament reconstructions (rACLR) than after primary anterior cruciate ligament (ACL) reconstructions. These outcomes are likely to be influenced by the status of the menisci and articular cartilage. Knees undergoing rACLRs have more intra-articular injuries than knees undergoing primary reconstruction as 90% of knees undergoing rACLR have been found to have meniscal or chondral injury while 57% had both at the time of rACLR. Meniscal injury and the amount of meniscus removed at ACL reconstruction have been shown to be associated with the subsequent development of arthrosis. In a previous study of the Multicenter ACL Revision Study (MARS) cohort, partial meniscectomies occurring before rACLR were shown to be associated with a higher rate of chondrosis at the time of rACLR compared with previous meniscal repair or no previous meniscal surgery. There was no difference in the prevalence of chondrosis in the knee between patients who had a previous meniscal repair and patients who had no previous meniscal surgery.
