Delayed tibial-platform periprosthetic stress fracture after unicompartmental knee arthroplasty: Uncommon and devastating complication

Publication date: December 2018 Source:Journal of Orthopaedics, Trauma and Rehabilitation, Volume 25 Author(s): Yuk-Wah Hung, Jason Chi-Ho Fan, Carson Ka-Bon Kwok, Ellis Lok-Fai Wong, Carman Ka-Man Lo Periprosthetic 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.
