Bursitis is a painful condition that affects the small fluid-filled pads – called bursae – that act as cushions among your bones and the tendons and muscles near your joints. Bursitis occurs when a bursa becomes inflamed.
The most common locations for bursitis are in the shoulders, elbows or hips. But you can also have bursitis by your knee, heel and the base of your big toe. Bursitis often occurs in joints that perform frequent repetitive motion.

Hip replacement surgery, also called total hip arthroplasty, involves removing a diseased hip joint and replacing it with an artificial joint, called a prosthesis. Hip prostheses consist of a ball component, made of metal or ceramic, and a socket, which has an insert or liner made of plastic, ceramic or metal. The implants used in hip replacement are biocompatible – meaning they’re designed to be accepted by your body – and they’re made to resist corrosion, degradation and wear.
Conditions that can damage the hip joint, sometimes necessitating hip replacement surgery, include:
Osteonecrosis, which occurs when there is inadequate blood supply to the ball portion of the hip joint
