Plain-English summary
A group of dogs with cranial cruciate ligament (CCL) disease underwent surgery to fix their knee joints, and researchers looked at how often they also had tears in the meniscus, a cartilage in the knee. Out of 357 dogs, about 32% had meniscal tears before surgery, and about 6% developed new tears afterward. Dogs with partial CCL tears were less likely to have meniscal issues compared to those with complete tears. All dogs that developed new meniscal tears after surgery were treated successfully and returned to normal function.

Abstract
OBJECTIVE: To determine the incidence of medial meniscal tears in dogs with naturally occurring cranial cruciate ligament (CCL) disease treated with arthroscopy and tibial plateau leveling osteotomy (TPLO). STUDY DESIGN: Retrospective case series. SAMPLE POPULATION: Canine Stifles (n = 357) with naturally occurring CCL disease. METHODS: Medical records (November 2006-November 2009) were reviewed for all dogs with CCL disease treated with arthroscopic CCL debridement, meniscal probing, and TPLO. We investigated the significance of the preoperative variables; age, weight, tibial plateau angle (TPA), sex, and the preoperative condition of the CCL on the prevalence of concurrent meniscal tears (CMT) and incidence of late onset meniscal tears (LMT). RESULTS: Prevalence of CMT and incidence of LMT was 32.2% and 5.6%, respectively. A significant difference between age of dogs with and without CMT was identified. There was a significantly lower prevalence of CMT and incidence of LMT in dogs that had a partial CCL tear compared with those that had a complete CCL tear. All dogs with LMT treated by partial meniscectomy (PMM) returned to peak postoperative limb function after (PMM) based on client-assessed outcomes. CONCLUSIONS: This study demonstrates the importance of LMT as a complication, the importance of comprehensive meniscal assessment, and may add to the evidence against routinely performing meniscal release in TPLO. The preoperative condition of the CCL should be considered before operating on grossly normal menisci.
