According to the Noyes Knee Institute, in 2005, approximately 27 million adults in the U.S. had osteoarthritis (in either the knees, hips, hands, or spine). By 2030, the number of adults with arthritis is expected to increase to 67 million, most of whom will have osteoarthritis.

Nearly 2 in 3 people who are obese may develop symptomatic knee osteoarthritis in their lifetime. 80% of patients with osteoarthritis have some amount of limitation of movement.

Regrettably, conservative methods do not always work to resolve pain, swelling, and limitations with sports or daily activities and surgery becomes necessary. This is especially true for patients who have lost a great deal of joint lining. There are no special medications, diets, or cures to stimulate the growth of normal cartilage in the knee joint. Cartilage does not have the ability to heal or repair itself and, once injured, the process of deterioration will gradually continue.

Many people think of total knee replacement as the operation used for knee arthritis; however, there are many other options. This is because the amount of arthritis may be mild, moderate, or severe and may involve one portion of the knee joint or several areas. 

Different Types of Knee Replacement Surgery

Here are the primary types of knee replacement surgery performed today by orthopedic surgeons. In each type of knee replacement surgery, the orthopedic surgeon resurfaces all or part of the knee and replaces it with artificial components, called implants.

  • Total Knee Replacement – The most common type of knee replacement surgery is total knee replacement. In a total knee replacement, the orthopedic surgeon removes damaged bone and cartilage in the shinbone and femur (thighbone) and replaces it with the knee implant components.
  • Partial Knee Replacement – Unicompartmental knee replacement, commonly referred to as a partial knee replacement or uni-knee, is possible in patients with strong knee ligaments who only have arthritis impact on one side of the knee. Only the damaged part of the knee needs to be replaced.
  • Kneecap Replacement – Though less common, in patellofemoral arthroplasty, or kneecap replacement surgery, the underside of the kneecap is replaced.
  • Complex Knee Replacement – Complex knee surgery is reserved for the most severe cases of osteoarthritis, or for patients who have already had several knee replacement surgeries. 
  • Revision Knee Replacement – In a revision knee replacement procedure, some or all of the parts of the original implant are removed and replaced with new components.
