Unicondylar knee prosthesis

A unicondylar knee prosthesis is a partial knee replacement designed to restore function to a single damaged compartment of the knee—either the medial or lateral side—where cartilage has worn away due to arthritis or injury. It replaces the bearing surfaces of the femur and tibia with metal or polyethylene components, preserving the healthy portions of the joint while improving mobility and reducing pain for patients with localized knee damage.

These devices are typically regulated as surgical implants, requiring compliance with medical device standards for sterility, biocompatibility, and structural integrity. They are supplied as sterile, implant-ready systems, often including fixation hardware, and are classified based on their risk profile and surgical context, though classification varies by jurisdiction. Always verify local regulations before use or procurement.
