We describe a case of heterotopic ossification (HO) of the lateral patella becoming symptomatic after 7 years following horizontal patella fracture. The patient presented peripatellar pain in full knee flexion and kneeling position. We resected the ossification, and the patient was immediately relieved from pain and was mobilised under full weight bearing with no limitation of knee flexion. The patient was able to return to his previous level of daily activities with no further episodes of pain. To our knowledge, this is the first case of heterotopic peripatellar ossification becoming symptomatic 7 years after a patellar fracture to be reported in the literature.
我们报告一例髌骨水平骨折7年后外侧髌骨异位骨化（HO）出现症状的病例。患者在膝关节完全屈曲和跪地时出现髌周疼痛。我们切除了骨化组织，患者疼痛立即缓解，在完全负重下活动，膝关节屈曲无受限。患者能够恢复到之前的日常活动水平，未再出现疼痛发作。据我们所知，这是文献中报道的首例髌骨骨折7年后髌周异位骨化出现症状的病例。
