Snapping pes syndrome is defined as a snapping sensation in the medial knee caused by pes anserinus and rarely occurs. Snapping pes syndrome after unicompartmental knee arthroplasty (UKA) has not been reported yet. We experienced two cases with this syndrome after UKA. Conservative treatment was effective in one case, while surgical excision of the gracilis tendon was necessary to relieve painful snapping in the other case. The main cause of the first case might be posteromedial overhang of the tibial tray that reached up to 5 mm. The probable cause of the second case was posteromedial overhang of the mobile bearing.
鹅足肌腱弹响综合征定义为鹅足导致的膝关节内侧弹响感,较为罕见。单髁膝关节置换术(UKA)后出现鹅足肌腱弹响综合征的情况尚未见报道。我们遇到了两例UKA术后出现该综合征的病例。保守治疗对其中一例有效,而另一例则需要手术切除股薄肌腱以缓解疼痛性弹响。第一例的主要原因可能是胫骨托后内侧悬突达5毫米。第二例的可能原因是活动平台的后内侧悬突。
