A 25-year-old national class distance runner came to our clinic complaining of inferior subpatellar pain. After initial diagnostic studies proved inconclusive, the patient was treated conservatively for patellofemoral arthralgia. After allowing him to return to participation following rest and rehabilitation, the patient continued to complain of pain. Further diagnostic studies (bone scan) revealed the presence of a longitudinal stress fracture of the patella. The patient was treated with nonweightbearing exercise and rest. After 8 weeks, he resumed training, and after 20 weeks he was competing on a national class level. This study implicates a patellar stress fracture as a possible etiology in a runner complaining of intractable patellofemoral pain that does not respond to conservative management.

一位 25 岁的国家级长跑运动员因髌下疼痛来我院就诊。初步诊断性研究结果不明确，故对患者行髌股关节炎的保守治疗。在休息和康复后允许其重返运动，患者仍诉疼痛。进一步的诊断性研究（骨扫描）显示髌骨存在纵向应力性骨折。患者行不负重运动和休息治疗。8 周后，他开始恢复训练，20 周后他重返国家级比赛水平。该研究提示，对于经保守治疗无效的顽固性髌股疼痛患者，髌骨应力性骨折可能是其病因之一。
