A polyethylene patella prosthesis is an implant used in knee replacement surgery to replace the natural kneecap (patella). It acts as a smooth, durable surface to help the knee joint move smoothly by articulating with the prosthetic femoral component, restoring function and reducing pain in patients with severe arthritis or trauma.
These devices are typically regulated as implants, often requiring clinical validation for safety and performance. They may be supplied sterile and pre-packaged for surgical use, with variations in design to suit different patient anatomies or surgical approaches. Classification and supply rules vary by jurisdiction, but they are generally considered high-risk medical devices due to their permanent implantation.
