Predictors of bone loss in revision total knee arthroplasty.
Revision total knee arthroplasty (RTKA) requires preoperative planning to enable the reconstruction of bony deficiencies. The objective of this project was to identify predictors of bone loss management at RTKA based on the preoperative failure mode and patient demographics known preoperatively. We retrospectively reviewed 245 consecutive RTKA procedures in which the same revision knee system was utilized. Patient demographic and treatment data were recorded, and locations of bone loss were identified based on the reconstructive management. We identified significant predictors for use of femoral augments at all four positions. Several predictors significantly predisposed to use of a thick (>19 mm) polyethylene; however, no predictors of tibial augments were significant. Although the reconstruction of bone loss is primarily based on the intraoperative assessment, these findings may provide additional information to help the surgeon prepare for difficult revision procedures.
