Summary
Distal femoral replacement (DFR) with rotating hinged (RH) prosthesis can lead to posterior dislocations, particularly in obese males with prior surgeries. This salvage procedure may necessitate above-knee amputation in severe cases.
Area of Science:
- Orthopedic Surgery
- Biomedical Engineering
Background:
- Distal femoral replacement (DFR) with rotating hinged (RH) prosthesis serves as a salvage procedure for total knee arthroplasty (TKA) complications.
- Complications following TKA can necessitate complex reconstructive surgeries.
