We present the case of a 17-year-old ice-hockey player, who complained about persistent left medial knee pain having undergone a refixation of a grade III osteochondritis dissecans with biodegradable pins, a reconstruction of the anterior cruciate ligament (ACL) and a medial meniscal repair 1 year previously. Sequential MRIs performed 8 and 12 months after surgery were inconclusive, and failed to show the insufficient integration of the osteochondral fragment. Combined single photon emission and conventional computerized tomography (SPECT/CT) clearly revealed the cause of the patient's persistent knee problems-the osteochondral fragment had not integrated. SPECT/CT may hold great clinical value for symptomatic patients who have previously undergone treatment for osteochondral lesions, and it should be considered as alternative diagnostic imaging modality.
我们报告了 1 例 17 岁冰球运动员的病例，他在 1 年前接受了 3 度骺软骨骨软骨炎的生物可吸收钉再固定、前交叉韧带（ACL）重建和内侧半月板修复后，持续出现左膝内侧疼痛。手术 8 个月和 12 个月后进行的连续 MRI 检查结果不确定，未能显示骨软骨碎片的融合不足。单光子发射和常规计算机断层扫描（SPECT/CT）的联合检查清楚地显示了患者持续性膝关节问题的原因——骨软骨碎片未融合。SPECT/CT 可能对先前接受过骨软骨病变治疗的有症状患者具有重要的临床价值，应将其视为替代诊断成像方式。
