A 21-year-old male division I collegiate athlete presented for right knee pain, effusion, and mechanical symptoms. The patient was found to have 2.4 × 2-cm medial patellar facet, 1 × 0.8-cm central trochlea, and 2.5 × 3-cm lateral femoral condyle articular cartilage defects on arthroscopy. The patient was treated with a matrix-induced autologous chondrocyte implantation (MACI) procedure for all 3 lesions. At 9 months postoperatively, the patient returned to full American football activities and remains asymptomatic 16 months postoperatively.
Multiple lesions and lesions involving the patellofemoral joint can be treated with a MACI procedure with short-term promising results in high-demand athletes.
一名 21 岁的一级大学生运动员因右膝疼痛、积液和机械症状前来就诊。关节镜检查发现患者的内侧髌骨面有 2.4×2cm、中央滑车有 1×0.8cm、外侧股骨髁关节软骨有 2.5×3cm 的缺损。患者接受了基质诱导的自体软骨细胞移植（MACI）治疗所有 3 处病变。术后 9 个月，患者重返美式足球的全部活动，术后 16 个月仍无症状。
多部位病变和髌股关节病变可采用 MACI 手术治疗，在高需求运动员中具有短期良好的效果。
