The Sigma® High Performance (HP) Partial Knee can replace any of the three areas of your knee, depending on the degree of arthritis damage. Replacing only the damaged area maintains more of your natural knee, helping to relieve pain and restore more natural movement. And because partial knee replacement is less invasive, you have the potential for a faster recovery than with a total knee replacement.
A Partial Knee Replacement may be an option for more active patients who require a high degree of flexion, but do not yet need a total knee replacement. It accommodates deep knee flexion, the movement needed for kneeling, squatting or sitting cross-legged. It may also make it easier for you to participate in social, cultural, religious or leisure activities that are important to you that require this type of bending.
