Plancher KO, et al. - This study was sought to ascertain the incidence of osteoarthritis (OA) in patients after anterior cruciate ligament reconstruction (ACLR) and lateral meniscus repair vs meniscectomy. Researchers distinguished all patients who had undergone primary autograft or allograft BPTB transtibial ACLR by a single surgeon between 1999-2015. The study enrolled a consecutive series of 85 patients (48 males, 37 females; age 38.5±10.9 years) with BPTB ACLR with an average follow-up of 8.69±4.88 (range 2-20 years). The data exhibited that individuals with lateral meniscal tears should be informed they have a 30% chance of developing Kellgren-Lawrence grade III-IV OA in the lateral compartment at approximately 9 years follow up. In comparison with lateral meniscus repair, these patients that undergo lateral meniscectomy have a 5 times greater odds of developing lateral compartment knee OA following lateral meniscectomy. The data exhibited that in contradistinction, successful repairs indicated a close to the negligible presence of OA in the lateral compartment. For lateral meniscus tears, they believe lateral meniscal repair is essential at the time of ACL reconstruction to help avoid the development of OA.
