Partial Knee Replacement (PKR), also known as unicompartmental knee replacement, is a minimally invasive surgical procedure designed for patients with localized knee arthritis or damage. Unlike Total Knee Replacement (TKR), which replaces the entire joint, PKR only replaces the damaged portion of the knee while preserving the healthy bone, cartilage, and ligaments.
This procedure offers faster recovery, less post-operative pain, and a more natural knee movement compared to total knee replacement. It is an excellent option for patients whose arthritis is limited to one compartment of the knee rather than affecting the entire joint.
PKR is recommended for patients who :-
✔️ Have osteoarthritis or joint damage limited to one area of the knee.
✔️ Experience chronic knee pain, stiffness, or swelling despite medication and therapy.
✔️ Have good knee ligament function and no severe deformity.
✔️ Are active and want to maintain a high level of mobility post-surgery.
✔️ Have not found relief from conservative treatments like physiotherapy and injections.
✅ Minimally Invasive – Smaller incisions, less tissue damage.
✅ Faster Recovery – Shorter hospital stays and quicker return to daily activities.
✅ Less Pain & Blood Loss – Compared to Total Knee Replacement.
✅ Better Knee Function – Retains natural movement and feel.
✅ Lower Risk of Complications – Such as infections or blood clots.
