title: Outcome of meniscal repair prior compared with concurrent ACL reconstruction.
abstract: Meniscal tears are commonly associated with traumatic rupture of the anterior cruciate ligament (ACL). At our centre, if a patient presents with locked knee in conjunction with an ACL injury we perform an initial arthroscopy to remove the cause of locking and schedule ACL reconstruction once a full range of motion has returned. The aim of this study was to assess the outcome of meniscal tears stabilised prior to ACL reconstruction. We identified 24 patients who underwent repair of a torn meniscus before having their ACL reconstruction (group 1). As a comparison group we identified 148 patients who underwent meniscal repair at the time of ACL reconstruction (group 2). Twelve of the patients in group 1 underwent meniscectomy, seven at the time of reconstruction and five subsequently. This gives a success rate of 50% (12/24) in the ACL deficient patients. In comparison forty two of the patients in group 2 went on to have a meniscectomy representing a success of 72% (106/148). The odds ratio for meniscectomy in an ACL deficient meniscal repair is 2.52 (95% CI 1.07-5.97) and there is a relative risk of 1.76 (95% CI 1.05-2.63). The difference in success of the meniscal repair between the groups was significant (Fisher's exact test p=0.05). Meniscal repair and delayed ACL reconstruction is more likely to fail than a combined repair and ACL reconstruction.
