Constrained polyethylene acetabular liners are implantable components used in total hip replacement surgery to replace the damaged socket of the hip joint. They fit inside an acetabular shell and provide a smooth surface for the femoral head to articulate with, improving mobility and reducing pain for patients with severe arthritis or hip damage.
These devices are typically regulated as surgical implants, often requiring pre-market approval or clearance depending on the jurisdiction. They may be supplied as standalone components or as part of a larger hip prosthesis system, with variations in design—such as added stabilization rings—to enhance stability and reduce dislocation risks.
