Total Joint Arthroplasties
Joint replacement surgery, also called a total joint arthroplasty (TJA), is a common procedure used to relieve pain, improve mobility, and restore quality of life. There are many types of joint replacement procedures. Joint replacement surgery is used to replace damaged cartilage and any loss of bone structure.
The procedure is a resurfacing of the damaged joint, which relies on the ligaments and muscles for function and support. The replacement joint is called a prosthesis, which can be made of cobalt chrome, stainless steel, titanium, ceramic, or polyethylene.
Osteoarthritis and Joint Dysfunction
The most common conditions that cause joint dysfunction are osteoarthritis and rheumatoid arthritis. Many factors contribute to joint degeneration and damage, which leads to arthritis. Factors include:
- Developmental abnormalities of the joint
- Minor repetitive injuries
- Abnormal cartilage metabolism
- Severe trauma to the cartilage
- Being overweight
Total Knee Replacement
The knee is the body’s largest joint, and it is necessary for walking, climbing stairs, and everyday activities. With age, excessive weight, and wear-and-tear from arthritis, the knee joint becomes damaged, making movement painful.
In a total knee replacement, the Gilbert orthopedic surgeon removes the degenerated cartilage surfaces at the ends of the shinbone (tibia) and thighbone (femur), and then replaces these areas with metal or plastic components. A spacer is inserted between the components so the joint will glide in a smooth fashion.
Patients who are candidates for a knee replacement are those with a knee deformity, people with chronic knee inflammation, persons who do not respond to conservative treatment, and anyone with limited movement of the knee. The Centers for Disease Control and Prevention (CDC) reports, in the U.S., more than 719,000 total knee replacements are performed each year.
Total Hip Replacement
The hip is a mobile joint, formed with a ball-and-socket. The ball and socket are both covered with articular cartilage, which can wear down from injury, trauma, or arthritis. This causes pain and limited mobility.
A total hip replacement involves removing the ball of the joint (femur head) and replacing it with a metal stem that attaches to the thigh bone. The damaged area of the socket is also replaced with a metal socket, and between these implants, the surgeon places a spacer that helps the joint glide easily. Candidates for a total hip replacement are patients who experience significant hip pain and stiffness, as well as people who have not responded to non-surgical methods. According to the CDC, there are more than 330,000 total hip replacements performed each year in the U.S.
Shoulder Joint Replacement
The shoulder joint consists of three bones: the humerus (upper arm bone), the clavicle (collarbone), and the scapula (shoulder blade). The shoulder is a ball-and-socket joint with cartilage on the ends of the structures to help them glide smoothly against one another. This cartilage breaks down due to arthritis and trauma, causing significant pain and loss of function. A total shoulder joint replacement involves use of prosthetic bone ends to replace the damaged areas. This surgical procedure is used for patients who do not respond to medications and those who have symptoms at rest.
Success Rates of Joint Replacement
The success rate of total joint replacement surgery is quite high. The need for repeat operation in the first ten years is less than 5%. Most replaced joints last from 10-20 years.
The Board Certified hip, knee and shoulder joint replacement surgeons at OSPI are highly skilled in the procedures. The Gilbert orthopedic surgeons offer contemporary, minimally invasive procedures that decrease postoperative pain, bleeding and speed recovery.
