Do knee replacement prostheses ever need to be replaced? The answer is yes, but they should last for decades. Dr. Dan Albright discusses the signs and symptoms that appear when it is time to for the prosthesis to be revised and how to make the one you have last longer.
Knee Replacement Surgery
The prevalence of obesity in the general population is increasing. Obesity is estimated to affect approximately one-third of adults in the United States. It is estimated that 6.1 million patients who undergo total joint arthroplasty will be obese by 2040.
Injury to the anterior cruciate ligament (ACL) in the knee frequently leads to early-onset osteoarthritis, a painful condition that can occur even if the patient has undergone ACL reconstruction to prevent its onset.
Osteoarthritis (OA), a chronic condition that causes the cartilage between the joints to wear out, is the most prominent form of arthritis. The absence of cushion causes bones to rub and grind together, causing swelling, stiffness, and pain. Doctors may prescribe physical therapy, a knee brace, or oral medication. However, if a patent continues to experience severe pain, swelling or extensive joint damage, knee injections or a full knee replacement is recommended.
Need another reason to keep your weight under control?
Excess weight can cause dislocation of your knee and may even lead to a complication that results in amputation of your leg.
A new study attributes a surge in dislocated knees to the U.S. obesity epidemic.
Two Patient Reported Outcomes that surgeons use to assess the success of arthroplasty are the Western Ontario and McMaster Universities (WOMAC) Osteoarthritis Index and the Oxford Knee Score.
