Abstract

This narrative review evaluates the purpose and functionality of rotating hinged total knee arthroplasty (RHTKA). The main indications for an RHTKA are poor bone stock, soft tissue compromise, gross instability, and periprosthetic fractures. Studies have shown that an RHTKA may be used in both the primary and revision scenarios to improve the range of motion and functional outcomes. Radiostereometric analysis has shown that some RHTKA designs are associated with early femoral component micromotion, but this has not translated to increased failure or revision rates. Implant survivorship with a modern RHTKA is comparable to a condylar-constrained TKA at mid-term follow-up. The most common complications associated with RHTKA are aseptic loosening, periprosthetic joint infection, stiffness and periprosthetic fractures.

Key words: Arthroplasty / Rotating hinged knee / Knee implants / Knee replacement / Implant survivorship
