Abstract

The authors report three cases of unicompartmental knee arthroplasty (UKA), complicated with perioperative periprosthetic fracture of the tibial plateau. The surgical technique was held responsible in all cases. The initial treatment was different in every case ; all patients ultimately underwent revision total knee arthroplasty with a good functional outcome. The authors emphasise the importance of careful preparation of the tibial plateau during UKA, adequate sizing of the tibial component and caution when using a hammer during implantation of the tibial component. When a tibial plateau fracture occurs, the treatment of choice should be immediate revision total knee arthroplasty.
