Knee pain is among the most common problems in active patients, with common causes of medial knee pain including meniscal injury, osteoarthritis, medial collateral ligament (MCL) injury, and pes anserine bursopathy/distal hamstring tendinopathy. Some cases of medial knee pain are refractory to standard treatment options and may be caused by rare pathology. We present a case of medial knee pain secondary to medial tibial crest friction syndrome (MTCFS) in a 22-year-old male training for a sprint triathlon after rapidly increasing his training program. Magnetic resonance imaging revealed bone marrow and soft-tissue edema about the MTC deep to the MCL consistent with MTCFS. The patient failed a period of relative rest and activity modification, but improved with corticosteroid injection deep to the MCL in the location of his symptoms. This case highlights a potential management option for MTCFS, a disorder previously described only in radiologic literature.
膝关节疼痛是活跃患者中最常见的问题之一，导致膝关节内侧疼痛的常见原因包括半月板损伤、骨关节炎、内侧副韧带（MCL）损伤和鹅足滑囊炎/ 远端腘绳肌腱病。一些膝关节内侧疼痛的病例对标准治疗方案无反应，可能由罕见的病理引起。我们报告了一例 22 岁男性在快速增加训练计划后，为参加短跑三项全能训练而导致的内侧胫骨嵴摩擦综合征（MTCFS）引起的膝关节内侧疼痛。磁共振成像显示 MCL 深部的 MTC 有骨髓和软组织水肿，符合 MTCFS。该患者经过一段时间的相对休息和活动调整后仍未改善，但在 MCL 深部症状部位接受皮质类固醇注射后症状得到改善。该病例突出了 MTCFS 的一种潜在治疗选择，这种疾病以前仅在放射学文献中描述过。
