OBJECTIVES: To assess a novel technique for arthroscopic evaluation of the canine stifle avoiding the need for fat pad debridement. STUDY DESIGN: Prospective study. SAMPLE POPULATION: Cadaveric canine stifles (n=10); Client-owned dogs (15). METHODS: In cadaveric stifles, the femoropatellar space was assessed before placement of a joint distractor and examination of the femorotibial joint. Time to complete evaluation of the femoropatellar space, to observe the cruciate ligaments, and to completion of examination of the femorotibial joint were recorded. Distractor-assisted arthroscopy was then performed in 15 consecutive clinical cases. Clinical information, time to complete joint evaluation, and ability to perform any additional arthroscopic surgery were recorded. RESULTS: Observation and palpation of intra-articular structures were possible in all cadaveric stifles. Mean time to evaluate the femoropatellar space was 3.2 minutes (range, 2-4 minutes); to observe the cruciate ligaments, 5.8 minutes (range, 3-8 minutes); and to completion of joint inspection, 9.1 minutes (range 6-13 minutes). In the clinical cases, observation of intra-articular structures was also possible in all stifles. Mean time to complete joint inspection was 21 minutes (range, 10-40 minutes). Partial meniscectomy was performed successfully in 5 stifles. CONCLUSIONS: Use of a joint distractor allowed arthroscopic observation of all relevant structures. Partial meniscectomy was readily performed. CLINICAL RELEVANCE: Use of a joint distractor may simplify arthroscopic assessment of the canine stifle and avoid potential morbidity associated with fat pad debridement.
