Currently two types of artificial joints are available in the market, the fixed and mobile bearing. The mobile bearing replacments are costlier, but reduce chances of early wear or loosening failure. The choice is usually made based on age, gender, occupation, disability level, pain intensity, interference with lifestyle and other medical conditions.

Currently, a majority of knee replacements are cemented into place. Cemented knee replacements have a generally excellent track record and may last more than 20 years. The longevity and performance of a knee replacement depends on several factors, including activity level, weight and general health.

Recently hybrid knee replacements are also done, where the femoral component is inserted without cement, and the tibial component is inserted with cement. These replacements also show positive results.
