Tarsal tunnel syndrome is an entrapment neuropathy of the posterior tibial nerve beneath the flexor retinaculum that can be precipitated by either intrinsic or extrinsic factors. We report a unique case of a posterior medial ankle joint capsular defect with localized fluid extravasation between the flexor digitorum longus and flexor hallucis longus leading to symptoms consistent with tarsal tunnel syndrome in a collegiate tennis player. This patient is a 19-year-old female with no past medical history who presented with symptoms consistent with tarsal tunnel syndrome. After confirmation with magnetic resonance imaging, the patient underwent capsular reconstruction with dermal allograft in combination with a tarsal tunnel release. The patient had improvement in pain and recovery of paresthesia 3 months postoperatively. At the latest follow-up of 1 year postoperatively, the patient has not had a recurrence of symptoms and has returned to the same level of competitive play. Many different causes of tarsal tunnel syndrome are described in the literature, but to our knowledge, there is no current literature that describes a defect in the tibiotalar joint capsule as a cause of tarsal tunnel syndrome.
跗管综合征是一种屈肌支持带下方胫后神经的卡压性神经病变，可由内在或外在因素诱发。我们报告了一例独特的病例，一名大学网球运动员的内踝后方关节囊缺损，在趾长屈肌和拇长屈肌之间有局限性液体外渗，导致出现与跗管综合征相符的症状。该患者为一名19岁女性，无既往病史，出现了与跗管综合征相符的症状。经磁共振成像确认后，患者接受了同种异体真皮移植的关节囊重建术并联合跗管松解术。患者术后3个月疼痛改善，感觉异常恢复。在术后1年的最新随访中，患者症状未复发，并已恢复到相同水平的竞技比赛。文献中描述了跗管综合征的许多不同病因，但据我们所知，目前尚无文献将胫距关节囊缺损描述为跗管综合征的病因。
