Partial Knee Replacement: 5 Things To Know

Partial knee replacement is a surgical option for individuals with damage confined to one part of the knee joint, often due to arthritis. Unlike total knee replacement, this procedure replaces only the damaged area, preserving more of the knee’s natural structure. This approach may help maintain the knee’s natural movement and support during activities. Recovery is quicker and knee flexibility is better maintained and improved. Here are five key points to learn about partial knee replacement.

1. How It Differs From Total Knee Replacement

Partial knee replacement addresses only the damaged area of the knee—either the inner, outer, or kneecap compartment—unlike total knee replacement, which replaces the entire joint. As a result, the surgery is less invasive, often involving a shorter operation and smaller incisions. Preserving more of the natural knee structure may also make post-surgery movement feel more natural.

2. Who Is a Suitable Candidate?

This procedure is best suited for individuals with arthritis or damage limited to a single knee compartment. It is commonly an option for younger, active patients who have no issues in other areas of the knee. However, for those with widespread knee damage, a total knee replacement may be necessary. An orthopaedic assessment will help determine the most appropriate treatment.

3. What to Expect During Recovery

Because partial knee replacement is less extensive, recovery time is typically faster than total knee replacement. Many patients are able to go home within 24 hours and experience less discomfort. However, physical therapy is necessary to regain strength, restore flexibility, and prevent complications. Patients should work closely with their therapist to optimise their recovery.

4. Improved Post-Surgery Mobility

Partial knee replacement preserves more of the natural knee structure, so patients often have a wider range of motion and fewer movement restrictions after surgery. Activities such as walking, light jogging, or cycling can usually be resumed sooner, which supports long-term joint health. High-impact activities should still be avoided until the knee is fully stabilised and approved by a doctor.

5. Longevity of Implant and Future Considerations

Partial knee replacements typically last between 10 and 15 years. While they may not last as long as total knee replacements, they can provide years of pain relief. Over time, natural wear and tear may necessitate further treatment, possibly even a total knee replacement. Regular follow-up appointments with your orthopaedic specialist are important to monitor knee health and plan any future care.

Conclusion

Partial knee replacement is an option for individuals with joint damage limited to one part of the knee, offering benefits such as quicker recovery and preserving more of the knee’s natural structure. However, it may not be suitable for those with extensive joint damage. Consulting an orthopaedic surgeon can help determine if partial knee replacement aligns with an individual’s health needs and activity levels.
