Publication date: December 2018Source: Journal of Orthopaedics, Trauma and Rehabilitation, Volume 25Author(s): Yuk-Wah Hung, Jason Chi-Ho Fan, Carson Ka-Bon Kwok, Ellis Lok-Fai Wong, Carman Ka-Man LoAbstractPeriprosthetic fracture around total knee arthroplasty (TKA) is a well-described complication. Yet, report of medial tibial plateau stress fracture after unicompartmental knee arthroplasty (UKA) is limited. One case of delayed stress fracture of medial tibial plateau after UKA, which was salvaged by conversion to TKA was reported. To the best of our knowledge, this is the first report related to Zimmer Unicompartmental High Flex Knee system (fixed bearing). The possible reasons were analysed, and tips and tricks to avoid this complication were shared. With reference to our case, osteoporosis should be considered as one of the relative contraindication for UKA. Meticulous surgical technique and avoiding multiple pin holes for tibial tray cannot be overlooked.中文摘要圍繞全膝關節置換術(TKA)的假體周圍骨折是一個充分描述的並發症。 然而, 單室膝蓋關節置換術 (UKA) 的內側脛骨平台應力骨折報告有限。 我們報告了UKA後內側脛骨平台的延遲疲勞性骨折的一例, 其通過轉化為TKA而被挽救。 據我們所知, 這是與Zimmer半單室人工膝關節置換術系統 (固定軸承) 有關的第一份報告。 我們分析可能的原因, 並分享我們的提示和技巧, 以避免這種併發症再次發生。我...
