Osteoarthritis of the knee joint is a condition in which the natural cushioning between joints, bones and cartilage wears away. This situation results in pain, swelling, stiffness and decreased range of the knee motion and ability to walk. This condition can occur even in young people but the chance of developing osteoarthritis rises after the age of 45 years. According to the Arthritis Foundation, more than 27 million people in the U.S. have osteoarthritis, with the knee being one of the most commonly affected areas. Women and obese patients are more likely to have osteoarthritis than men. In patients with severe deformity and advanced stages of osteoarthritis the surgery may be indicated. The standard for treatment of advanced stages of osteoarthritis is Total Knee Arthroplasty (TKA), which give patients relieve pain and increase range of the joint motion. Knee Replacement Surgery can be performed as a partial or a total knee replacement, however the total knee replacement is most common performed. To improve the results of TKA many different techniques were employed for this procedure. One of those is the use of navigation system during surgery. In the Clinic of Orthopedics and Pediatric Orthopedics Medical University of Lodz, the total knee arthroplasty is routinely performed since 1986. The aims of this study was to compare the results of total knee arthroplasty performed with the use of navigation system and with conventional knee arthroplasty and to evaluate the effectiveness of navigation system to support total knee arthroplast.
