Articular cartilage scores in cranial cruciate ligament‐deficient dogs with or without bucket handle tears of the medial meniscus

Objective To compare articular cartilage scores in cranial cruciate ligament (CCL)‐deficient dogs with or without concurrent bucket handle tears (BHT) of the medial meniscus. Study Design Retrospective case series. Animals Client‐owned dogs treated with arthroscopy and tibial plateau leveling osteotomy or extracapsular repair for complete CCL rupture (290 stifles from 264 dogs). Methods Medical records and arthroscopic images were reviewed. Medial femoral condyle (MFC) and medial tibial plateau (MTP) cartilage was scored using the modified Outerbridge scale. Periarticular osteophytosis (PAO) and injury to the medial meniscus were recorded. Data were analyzed using Student's t‐tests, Wilcoxon rank‐sum test, and Fisher's exact test for changes in the stifle based on meniscal condition, body weight, and duration of lameness. Results PAO, MFC, and MTP articular cartilage scores were not significantly different in dogs with or without BHT. There were no significant differences in MFC or MTP scores when dogs were evaluated based on bodyweight and the presence or absence of a BHT. However, PAO formation was significantly increased in dogs weighing >13.6 kg and concurrent meniscal injury vs. dogs weighing
