Osteochondral defects (OCD) are rare conditions that usually present in young adolescents. The causes include trauma, inflammation, ischaemia, genetics and changes at secondary ossification centres. The case report presents a 27-year-old man with chronic intermittent left knee pain for about 3 years. He typically develops the symptom after prolonged standing or when rising from a prolonged seated position. An initial MRI scan in 2014 did not identify and report an OCD that was present in his left lateral tibial plateau. It was only after an accidental tibial fracture injury this year that the defect was incidentally detected on a scan. OCD can be staged based on MRI and/or arthroscopic findings. The treatment can be either non-operative or operative, but this largely depends on the age of the patient, the severity of symptoms and the staging of the defect.
骨软骨损伤（OCD）是一种罕见病症，通常出现在青少年中。其病因包括创伤、炎症、缺血、遗传以及继发骨化中心的变化。该病例报告介绍了一名27岁男性，其左膝慢性间歇性疼痛约3年。他通常在长时间站立后或从长时间坐姿起身时出现症状。2014年的初次磁共振成像（MRI）扫描未识别并报告其左胫骨外侧平台存在的骨软骨损伤。直到今年意外发生胫骨骨折受伤后，才在扫描中偶然发现该缺损。骨软骨损伤可根据MRI和/或关节镜检查结果进行分期。治疗方法可以是非手术治疗或手术治疗，但这在很大程度上取决于患者的年龄、症状严重程度和缺损分期。
