- Rheumatoid arthritis (a chronic inflammatory disease that causes joint pain/stiffness/swelling)
- Post-traumatic arthritis
- Avascular necrosis (or osteonecrosis, which is the death of bone caused by insufficient blood supply)
- Injury, fracture, and bone tumors
- Childhood hip disease
During hip replacement, a surgeon removes the diseased/damaged sections of your hip joint and replaces them with metal and hard plastic parts. This artificial joint, or prosthesis, helps reduce pain and improve function. In a total hip replacement, the damaged bone and cartilage is removed and replaced with prosthetic components.
