Objectives: To evaluate and compare detection of meniscal tears associated with cranial cruciate ligament insufficiency by either arthroscopy or arthrotomy. %26lt;br%26gt;Methods: A retrospective, cohort study was completed with stifles (n = 531) of dogs with cranial cruciate ligament rupture. Either a medial parapatellar arthrotomy or an arthroscopy procedure was performed and groups were compared for significant differences in meniscal tears detected using logistic regression analysis. %26lt;br%26gt;Results: Arthroscopy was performed on 58.8% and arthrotomy on 41.2% of the stifles. In total, 44.4% of the examined stifles had meniscal tears. Meniscal tears were found in 38.8% of the stifles examined by arthrotomy, and 48.4% of those examined by arthroscopy. Overall, the rate of detection of a meniscal tear was significantly different (p = 0.019) between the groups, and meniscal tears were observed more frequently by arthroscopy than by arthrotomy (odds ratio 1.54; 95% confidence interval 1.07 - 2.22). %26lt;br%26gt;Clinical significance: These results suggest that arthroscopy may be more sensitive than arthrotomy for detection of meniscal pathology in clinical patients. However, these results must be interpreted with caution since this was a retrospective study. Randomized prospective clinical studies are required to further test this hypothesis.
