| Abstract: | With the rising numbers and indications of primary as well as revision total knee arthroplasty (TKA), managing bone defects around the knee is an emerging challenge. This retrospective study evaluates the outcomes of Trabecular Metal (TM) cones used to address bone defects in 79 (20 primary and 59 revision) TKA cases. Range of motion and Knee Society Score improved significantly postoperatively, with better outcomes in the primary TKA group. Complete osteointegration was observed in all the cases. At an average follow-up of 6.6 years, major complications requiring re-operation were seen in 4 (5%) knees. TM cones are an effective option for treating severe bone defects during TKA with predictable osteointegration and good long-term clinical outcomes. |
