What is osteoarthritis?
Osteoarthritis (OA) is the most common cause of loss of mobility in America. It is the wearing out of a joint. Primary osteoarthritis occurs, most commonly, in weight-bearing joints in people over the age of 50. There is a reported higher incidence of osteoarthritis of the knees in obese women than in obese men. While the origin of this condition is usually unknown, it can be traced in some people to conditions that produce incongruity in joint surfaces.
What are the symptoms?
Pain and stiffness of the knees are the first symptoms noticed by patients. The pain is worse with weight bearing and is relieved by rest. As the condition progresses, swelling and joint deformity may occur. These symptoms are usually progressive, however, the rate of progression varies from patient to patient.
What are my options for surgical treatment?
The treatment of mild to moderate osteoarthritis is usually nonsurgical and may include nonsteroidal anti-inflammatory medications, analgesics, physical therapy, bracing, orthoses, cane use, and weight reduction. When symptoms are severe, surgery is indicated. A typical patient who is a candidate for a total knee replacement can walk fewer than three blocks because of pain and has pain at night and/or at rest.
What are my options for knee replacement?
The surgical options for the treatment of osteoarthritis include:
- Total knee replacement
- Knee fusion
- High tibial osteotomy
- Partial total knee replacement
Total knee replacement gives the most consistent and good functional results while at the same time maintaining the movement of the knee joint.
How long will a total knee replacement last?
The knee replacement will give 12 to 15 years of service. When they become worn, they can be replaced with anticipated good functional results.
