Partial knee replacement is a surgical procedure designed to relieve pain and restore function in patients with arthritis that affects only part of the knee. Unlike total knee replacement, which replaces the entire joint, partial knee replacement focuses only on the damaged compartment, preserving healthy bone and tissue. This approach often results in faster recovery, less post-operative pain, and a more natural knee feel. Ideal candidates are patients with limited arthritis and intact ligaments. The procedure typically requires a smaller incision and can significantly improve the quality of life of eligible patients.
