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.

The Latest Advancements in Knee Replacement for Active Boomers

The majority of patients coming in for knee replacement surgery are in their 50s, according to Steven Haas who is heading the Knee Surgery and Attending Orthopedic Surgeon Department at the Hospital for Special Surgery based in New York City. If these statistics are compared with those of 20 years ago, there has been a rapid shift in demand for knee replacement surgery, especially for people in their 50s.

Why the sudden interest and growth of demand for the surgical procedure? The points responsible for this are new and innovative technologies that are being used now, especially in implant design and far more improved surgical techniques that are being used by orthopedic surgeons to meet with the growing demand for knee replacements. In addition, the growing number of baby boomers reaching older age has increased the numbers in need of the procedure.

The Latest in Knee Replacement Surgery

Only recently, the orthopedic community announced the arrival of the newest advancement for the surgery, i.e. a knee replacement implant that can last the patient as much as 30 years instead of the standard 10-15. Moreover, the implant has also been cleared by the FDA which means that those looking for ways to make their implants last longer, can opt for this.

VERILAST technology is used for making the implant that will make it possible for patients to possibly outgrow the implant, rather than the other way round. In addition to this, the implants are thought to be much more functional than the earlier versions, as is proved by a series of tests that researchers underwent before giving that verdict.

Adoption of Better Surgical Procedures and Techniques

Orthopedic surgeons have also changed their way of performing surgical procedures, by introducing techniques such as minimally invasive surgery, which helps in decreasing trauma to the patient, as much as possible, which in turn leads to a faster recovery.

Another development is the usage of small surgical instruments for performing the procedure, where the goal is to cut as little as possible, which will minimize the collateral damage and trauma that came with previous surgical procedures that were extremely invasive in nature.

Better Recovery Rate Due To Minimal Invasive Surgical Procedures

The entire point of such a surgery is not to make the cut big enough to fit the instruments, but rather, to use smaller instruments during the procedure that would best fit the cut made. This is the reason why, smaller incisions are used to get access to the knee area after providing local anesthetic to the patient.

One point in favor of the minimal invasive procedure is that, no need is felt to cut the quadriceps tendon or flip the kneecap upside down in order to gain access to the area, which was required in the case of previous surgical techniques. This has also improved the recovery rate far more significantly and at a much faster rate, than old surgical techniques, so now patients are up and about after only 6 weeks of having the procedure done as compared to 3 months.
