    Methods: A retrospective case control study was performed of dogs that had undergone surgery for cranial cruciate ligament rupture. Data recorded included patient signalment (age, breed and sex), the duration of the lameness, the extent of the cranial cruciate ligament rupture (complete or partial) and the condition of the medial meniscus. Logistic regression was used to analyse the relationship between these variables and tears in the medial meniscus.

    Results: One hundred and sixty-one of 443 stifles (36 center dot 3%) in 366 dogs had a medial meniscal tear. The risk of a medial meniscal tear was increased by 12 center dot 9 times in association with complete cranial cruciate ligament rupture (OR 12 center dot 9; 95% CI 6 center dot 8 to 24 center dot 2), by approximately 2 center dot 6% for each additional week of lameness (OR 1 center dot 026; 95% CI 1 center dot 009 to 1 center dot 043) and by approximately 1 center dot 4% for each additional kilogram of bodyweight (OR 1 center dot 014; 95% CI 1 center dot 000 to 1 center dot 028). Golden retrievers and Rottweilers were at increased risk and West Highland white terriers were at reduced risk of medial meniscal tears compared with Labrador retrievers.

    Clinical Significance: To minimise the risk of medial meniscal tears, surgical stabilisation should not be unnecessarily delayed.
