Concurrent meniscal injury in dogs with cranial cruciate ligament tears ranges from 10-70%, and these injuries can increase the risk of developing osteoarthritis. Studies regarding joint space width on knee radiographs in people have indicated correlations between joint space width and meniscal injuries. The aim of this study was to determine if there was correlation between stifle joint space width on three different radiographic projections and meniscal injuries identified at surgery in dogs. Four blinded observers measured the radiographic joint space width three times, and the measurements were compared to surgical findings. Intraclass correlation coefficients for inter- and intraobserver variability ranged from moderate to excellent. There was significance between dogs with a meniscal tear and the corresponding joint space width on standard TPLO lateral radiographic projections. Joint space narrowing is seen with meniscal tears in dogs, and radiography may be a noninvasive way to identify meniscal tears prior to surgery.
