Unicompartmental knee replacement, also known as partial knee replacement, is a surgical procedure performed when only one compartment of the knee joint is damaged by arthritis. Unlike total knee replacement, this technique preserves the healthy parts of the knee, allowing for a more natural movement and faster recovery. This procedure is ideal for patients with medial or lateral knee osteoarthritis who do not require a full knee replacement.

What Is It?

A minimally invasive procedure that replaces only the damaged portion of the knee joint with an implant, leaving the rest of the knee intact. This results in quicker rehabilitation and less post-operative pain compared to total knee replacement.

Symptoms Treated

• Osteoarthritis affecting only one side of the knee
• Chronic knee pain that is localised to a single compartment
• Difficulty with walking, bending, or weight-bearing activities

Postoperative Care

• Physiotherapy to regain movement and strength
• Weight-bearing as tolerated, often within a few days
• Less recovery time than a total knee replacement

Risks and Complications

• Implant wear over time
• Progression of arthritis in other knee compartments
• Possibility of revision surgery if arthritis worsens
