Twenty-three American football participants were studied 20 years after high school competition, as well as 11 age-matched controls, to assess the development of knee osteoarthritis. No statistically significant increase in osteoarthritis could be demonstrated radiographically, subjectively, or objectively. A significant increase in knee joint osteoarthritis was found in the subgroup of football players who had sustained a knee injury.
对23名高中毕业后20年的美式橄榄球运动员以及11名年龄匹配的对照组进行了研究，以评估膝骨关节炎的发展情况。在影像学、主观或客观方面均未发现骨关节炎有统计学意义的增加。在遭受过膝关节损伤的橄榄球运动员亚组中，发现膝关节骨关节炎有显著增加。
