Investigation of 133 knees with Blount's disease in 86 patients showed that no patient below the age of 30 had evidence of degenerative change in the affected knees. Seventeen patients over 30 years of age had a total of 27 affected knees, of which 11 were osteoarthritic. Although increasing varus deformity predisposed to degenerative change the relationship was not constant and no firm relationship could be drawn between the amount of wear, the compartment of the knee involved and the degree of deformity.
对86例患有布朗特病的133个膝关节进行的调查显示，30岁以下的患者中，受累膝关节均无退行性改变的迹象。17例30岁以上的患者共有27个受累膝关节，其中11个患有骨关节炎。尽管内翻畸形增加易导致退行性改变，但这种关系并不恒定，磨损程度、膝关节受累部位与畸形程度之间无法得出确切的关系。
