The patella is the largest sesamoid bone in the body and an important structure of the extensor apparatus which is under undue stress during flexion and extension of the knee. Bilateral fracture of the patella without trauma is a very rare event and may be multifactorial without a single cause. A repetitive stress reaction in a previously predisposed bone can be an important cause. We report a case of a 45-year-old female with a nontraumatic bilateral transverse patella fracture with loss of extensor mechanism. A stable surgical fixation for such a displaced fracture with a good rehabilitation program can lead to a good functional outcome.
髌骨是人体最大的籽骨,也是伸膝装置的重要结构,在膝关节屈伸过程中承受着过度的应力。无外伤的双侧髌骨骨折是一种非常罕见的情况,可能是多因素导致的,没有单一原因。先前易患的骨骼中反复的应力反应可能是一个重要原因。我们报告一例45岁女性,患有非创伤性双侧髌骨横行骨折并伴有伸膝装置丧失。对于这种移位骨折采用稳定的手术固定并配合良好的康复计划可取得良好的功能结果。
