It has been hypothesized that patellofemoral pain, a common knee condition in adolescents and young adults, may be a precursor of degenerative joint changes and may ultimately lead to patellofemoral osteoarthritis. Since both conditions share several mechanical disease characteristics, such as altered contact area between the femur and patella and increased joint stress, we investigated whether these conditions share similar and different shape characteristics of the patella compared with normal controls.

髌股关节疼痛是骨关节炎的前兆吗？：与健康对照组相比，髌股关节骨关节炎和髌股关节疼痛患者的髌骨形状异常。

据推测，髌股关节疼痛是青少年和年轻人常见的膝关节疾病，可能是退行性关节变化的先兆，并可能最终导致髌股关节骨关节炎。由于这两种情况具有几种机械疾病特征，例如股骨和髌骨之间的接触面积改变和关节应力增加，我们研究了这些情况与正常对照组相比是否具有相似和不同的髌骨形状特征。
