Patellar tendinopathy is characterized by activity-related anterior knee pain. It is most commonly related to sports activity, but has also been reported in the non-athletic population. Most injuries are caused by microtrauma, resulting in tendinitis or tendinosis. Extraskeletal paraarticular osteochondromas, which occur in the soft tissues near the joint, are rare. The infrapatellar fat pad and joint capsule are the most common sites of these tumors. Here, a case of patellar tendinitis caused by an extraskeletal paraarticular osteochondroma is reported. The symptoms included intensifying pain upon flexion and a palpable click that was located at the medial side of the mass. The patient was pain-free within 3 weeks after excision of the tumor and the clicking disappeared. To our best knowledge, no other case of patellar tendinitis caused by an extraskeletal paraarticular osteochondroma has been reported in the English literature.
髌腱病的特征是与活动相关的膝前疼痛。它最常见于与体育活动相关，但在非运动员人群中也有报道。大多数损伤是由微创伤引起的，导致肌腱炎或肌腱病。关节外关节旁骨软骨瘤发生在关节附近的软组织中，较为罕见。髌下脂肪垫和关节囊是这些肿瘤最常见的部位。在此，报告一例由关节外关节旁骨软骨瘤引起的髌腱炎病例。症状包括屈曲时疼痛加剧以及在肿块内侧可触及的咔嗒声。肿瘤切除后3周内患者疼痛消失，咔嗒声也消失了。据我们所知，英文文献中尚未报道过其他由关节外关节旁骨软骨瘤引起的髌腱炎病例。
