Unicondylar arthroplasty, also known as partial knee replacement, is a surgical procedure that replaces only the damaged compartment (medial, lateral, or patellofemoral) of the knee joint—rather than the entire joint. It is typically recommended for patients with localized osteoarthritis affecting a single compartment of the knee. At Rapha, our orthopaedic team performs unicondylar replacements using precise, minimally invasive techniques to preserve healthy bone and ligaments. This results in faster recovery, less post-operative pain, and a more natural-feeling knee compared to total knee replacement. Ideal candidates are usually active individuals with good range of motion, stable ligaments, and arthritis limited to one part of the knee. Post-surgery, patients undergo a tailored physiotherapy program focused on restoring mobility, strength, and function.
