Partial Knee Replacement (Unicompartmental Knee Arthroplasty)

What is Partial Knee Replacement (Unicompartmental Knee Arthroplasty)?

A surgical procedure to replace only the damaged part of a knee joint with an artificial implant.
Unlike total knee replacement, which replaces all three compartments of the knee, partial knee replacement focuses on a specific area, usually the inner (medial) or outer (lateral) part of the knee.

When is Surgery Necessary?

  • Limited Arthritis: Suitable for patients with arthritis that is confined to a single compartment of the knee.  
  • Healthy Remaining Cartilage: Requires healthy cartilage and ligaments in the other parts of the knee.  

Surgical Procedure

  • Smaller Incision: Typically involves a smaller incision compared to total knee replacement.  
  • Removal of Damaged Bone and Cartilage: The surgeon removes only the damaged bone and cartilage from the affected compartment. 
  • Implantation: An artificial implant, usually made of metal and plastic, is inserted to replace the damaged surface.

Recovery

  • Shorter Hospital Stay: Often requires a shorter hospital stay compared to total knee replacement.  
  • Faster Recovery: Generally allows for a quicker recovery and return to normal activities.  
  • Less Pain: May result in less post-operative pain compared to total knee replacement.
