The Minimally Invasive Knee Retractors are designed to retract tissues and access damaged bones during knee arthroplasty and other knee surgeries. They allow surgeons to retract soft tissues, such as muscles and ligaments, without the need for extensive dissection, hence preserving tissue integrity. These retractors are specifically designed for procedures involving the patella, tibia, and femur, making them ideal for minimally invasive surgeries.
