Charnley

Charnley refers to a common type of hip replacement design developed by Sir John Charnley in the 1960s. It features a small metal ball (femoral head) connected to a metal stem inserted into the thigh bone, paired with a specially designed low-friction plastic socket (acetabular component) fitted into the pelvis. This design aims to mimic natural hip movement while reducing wear and improving longevity. Charnley's approach revolutionized hip surgery by providing durable, reliable joint replacements that help restore mobility and reduce pain for patients with hip joint damage.
