How Do You Know If You Need Partial Knee Replacement?
Bone-on-bone arthritis on X-ray, pain that limits daily life, and failed non-surgical treatment.
The combination that points to UKA: pain that interferes with sleep, work or activities you value; X-rays showing bone-on-bone arthritis confined to one compartment; and conservative treatment (anti-inflammatories, weight loss, physiotherapy, injections) no longer controlling symptoms.
It is not the X-ray alone — many people have impressive X-rays and minimal pain — and it is not the pain alone. The decision is the combination, plus the Knee Check or in-person assessment confirming that the pattern is suitable for partial rather than total replacement.
If you are unsure, our Knee Check provides an initial guide, and a consultation gives you a definitive answer with KOGS grading.
