Knee Fusion following TKR Wheeless

Description: Arthrodesis remains a treatment option for patients who have recurrent infection, or who are poor candidates for reimplantation;
- problems inherent in the performance of knee arthrodesis following a total knee arthroplasty complicated by infection are bone loss, shortening, gait disturbance, & inability to eradicate infection;
- fusion rates of revised knee arthroplasties are all significantly lower than primary knee arthrodesis rates.
- total knee arthroplasty of the unconstrained or semiconstrained types in multiple series were easier to fuse than constrained total knees;
- reduction in bone stock as caused by infection further decreases fusion rate;
