Total Hip Arthroplasty
Total hip arthroplasty is the complete replacement of a damaged hip with a prosthetic one. This surgery is performed to relieve pain and restore function to a hip deteriorated by osteoarthritis, rheumatoid or psoriatic arthritis, avascular necrosis, congenital abnormalities or traumatic injury. Total hip arthroplasty involves replacing the entire diseased joint, composed of the natural ball and socket and its protective cartilage. The damaged joint is replaced with a prosthetic hip, usually made of a metal ball and a plastic socket.
The artificial hip will help the patient to move more normally and without pain. While total hip arthroplasty has a very high rate of success (90-95 percent), this surgical procedure is normally considered only after more conservative treatments have proven ineffective.
Total Knee Arthroplasty
Patients with severe pain and stiffness that does not respond to conservative treatments or more moderate surgery may require total knee arthroplasty, commonly known as knee replacement, to relieve pain and restore function. Whereas in a healthy knee smooth cartilage cushions the connecting bone ends, when osteoarthritis develops, the resulting pain and stiffness that may require surgical intervention.
In a total knee arthroplasty, the damaged ends of the bones are removed and replaced with a prosthesis made of metal and plastic. These artificial parts allow the joint to move smoothly so the patient experiences pain relief and a better quality of life.
Severe shoulder conditions with persistent symptoms that have not responded to conservative treatments may benefit from shoulder arthroplasty, or shoulder joint replacement surgery. Shoulder arthroplasty is a procedure in which the damaged joint is replaced with an artificial joint that allows patients to enjoy painless motion and resume their regular activities. Joint replacement of the shoulder is not performed as frequently as that of the hip or knee, but it is equally effective in improving a patient’s comfort and use of the affected arm.
