Total Joint Replacement at OSPI – AZ Orthopedic Surgeons

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 jointknee replacement
  • Heredity
  • 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 coveredcanstockphoto24680715(1) 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.

Are Orthopedic Knee Braces Helpful In Preventing Or Treating Injuries?

This has been a controversial topic for a very long time. On one hand, knee braces can be used and are suggested by most orthopedic surgeons to help in a variety of conditions and problems, but there’s still the question of “Do they really help?”; which needs to be answered.

There are two types of basic knee braces that your orthopedic surgeon might suggest depending on the situation; Functional and Prophylactic knee braces.knee brace

Functional Knee Braces

Patients who are already suffering from a ligament injury are the ones concerned about the effectiveness of knee braces. In such cases, they are usually interested in the functional knee brace type, because they are specially designed to support a torn knee ligament. This means the knee braces can prove beneficial if the patient’s already suffering from a ligament injury, as further confirmed by a number of studies done on the subject.

In summary; functional knee braces are fully able to provide at least some protection to the knee, particularly when force is applied. The studies done, further examined that the knee with the brace is more stable as compared to without it.

Prophylactic Knee Braces

Specifically designed to prevent knee injuries from happening in healthy athletes, these knee braces were first made available and highly popularized in the late 1970s when they were tried and tested by NFL players. Since then, use of prophylactic knee braces has only increased with the positive results shown by several studies, regarding the injury rate of athletes wearing the braces as compared those who don’t.

Although the difference isn’t questionably large, they do show that athletes of certain sports such as football; have a much lower rate of contraKnee Bracecting an MCL injury, when wearing the brace. Some important factors however, should be taken into account as well when determining the likelihood of injury, such as;

  • The sport played
  • The position of the player
  • The conditioning of the player
  • The size and weight of the player

At first; there was a huge concern with regard to usage of prophylactic knee braces. It was said that they could potentially alter the force on the knee which could very well become problematic. This isn’t the case at all, because when fitted and worn properly, they have shown to decrease the rate of ankle injuries.

OSPI offers bracing for clients for both types. This includes braces that are either custom made or potentially “off the shelf”. Insurance often covers them. Call OSPI today at (480) 899-4333.
