Total Knee Replacement After Partial Knee Replacement: Revision Considerations

Total knee arthroplasty (TKA) replaces the entire joint; partial (unicompartmental) replacement addresses only one compartment (medial or lateral). Partial is suitable for isolated arthritis; TKA is indicated when arthritis involves multiple compartments or revision is needed.

Many experienced orthopedic surgeons specialize in revision TKA after prior partial replacement. They assess:

• Extent of arthritis progression
• Stability of the existing implant and knee
• Bone quality and alignment

If you’re considering conversion to TKA, consult a fellowship-trained knee revision surgeon for a thorough evaluation.
