During the surgery, the partial knee replacement surgeon removes the damaged cartilage and bone from the affected compartment, and replaces it with a prosthetic implant. The procedure is less invasive, and the recovery period is generally shorter, allowing patients to return to daily activities sooner. Unlike total knee replacement, this approach allows for more natural movement, as the healthy parts of the knee are preserved. It also tends to result in less post-operative discomfort and faster rehabilitation.
