The effects of surgical and nonsurgical therapy on the development of osteoarthritis were compared in 12 dogs with bilateral medial patellar luxation and unilateral surgical repair. Evaluations included severity of lameness and patellar luxation, ligamentous stability, range of motion, and radiographic evidence of osteoarthritis before surgery and at a mean of 33 months after surgery. Stifles without surgical treatment served as controls for the contralateral stifles with surgery. All stifles treated surgically had reduced patellofemoral joints, normal range of motion, and improved limb use. Osteoarthritis progressed significantly and comparably in both groups of stifles. Progression of osteoarthritis was not correlated with luxation grade, body weight, or interval from surgery to follow-up. Age at surgery was correlated positively with severity of osteoarthritis in the stifles treated surgically.
对12只患有双侧内侧髌骨脱位且接受单侧手术修复的犬，比较了手术和非手术治疗对骨关节炎发展的影响。评估内容包括跛行和髌骨脱位的严重程度、韧带稳定性、活动范围，以及术前和术后平均33个月时骨关节炎的影像学证据。未接受手术治疗的 stifles作为接受手术治疗的对侧 stifles的对照。所有接受手术治疗的 stifles髌股关节均缩小，活动范围正常，肢体使用情况改善。两组 stifles的骨关节炎均显著且同等程度地进展。骨关节炎的进展与脱位等级、体重或手术至随访的间隔时间无关。手术时的年龄与接受手术治疗的 stifles中骨关节炎的严重程度呈正相关。
