The P.F.C.“ Sigma Knee has a history of success dating back to 1984. Thousands of people have had it implanted with outstanding results. The P.F.C. Sigma knee has been designed to act much like a natural knee. The design also increases the stability of the replacement knee. The innovative design distributes pressure evenly throughout the joint, which may reduce wear and tear. Each knee is unique. To provide the best match for your knee, Dr. Caillouette can choose from a number of implant sizes and parts in the P.F.C. Sigma System. Five to 10 years after surgery, most people with P.F.C. Sigma Knee implants reported that the surgery had resulted in excellent relief of pain, improved range of motion and better function of the knee.
