Total Hip Replacement

Definition

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.

Mechanism of injury

Hip replacement is typically used for people with hip joint damage from arthritis or an injury. Followed by rehabilitation, hip replacement can relieve pain and restore range of motion and function of your hip joint.

  • Osteoarthritis usually occurs in people 50 years of age and older and often individuals with a family history of arthritis. It may be caused or accelerated by subtle irregularities in how the hip developed. In this form of the disease, the articular cartilage cushioning the bones of the hip wears away. The bones then rub against each other, causing hip pain and stiffness.
  • Rheumatoid arthritis is an autoimmune disease in which the synovial membrane becomes inflamed, produces too much synovial fluid, and damages the articular cartilage, leading to pain and stiffness.
  • Traumatic arthritis can follow a serious hip injury or fracture. A hip fracture can cause a condition known as osteonecrosis. The articular cartilage becomes damaged and, over time, causes hip pain and stiffness.

Symptoms

Moderate to severe hip pain over a longer period of time or acute pain following an injury where the hip joint has been damaged severely usually followed by pain with movement such as walking, stairs, squatting and bend forward.

Physical Therapy Intervention

Rec Center Physical Therapy can be the first line of defense for those suffering from a total hip replacement by offering treatments such as gait training with or without an assistive device, hip range motion, hip strengthening, gentle stretching, balance training/ fall prevention training.
