About the procedure
A unicompartmental replacement resurfaces only the affected part of the knee. It is an option for selected patients whose arthritis is limited to one compartment.
Planning your treatment
Assessment considers ligament function, knee alignment and where the arthritis is located. A total replacement may be more appropriate if damage is more widespread.
Questions to discuss with your clinician
Use this guide to prepare for an individual discussion. The right next step depends on your diagnosis and circumstances.
- What is the aim of this treatment in my situation?
- What are the alternatives, including non-surgical care where appropriate?
- Which risks matter most for my health and the planned procedure?
- What preparation, rehabilitation and help at home might I need?
- How will progress be reviewed, and who should I contact with concerns?
Common questions
How is it different from a total replacement?
A partial replacement treats one compartment; a total replacement resurfaces more of the joint.
Could I need further surgery later?
Yes. Arthritis may progress elsewhere in the knee, or the implant may develop a problem. These possibilities are part of the preoperative discussion.
