The ends of those 3 bones wherever they touch are coated with articular cartilage, a sleek substance that protects the bones and allows them to maneuver simply.
The menisci are situated between the femur and leg bone. These C-shaped wedges act as "shock absorbers" that cushion the joint.
Large ligaments hold the thighbone and leg bone along and supply stability. The long thigh muscle provides the knee strength.
All remaining surfaces of the knee are coated by a thin lining referred to as the synovial membrane. This membrane releases a fluid that lubricates the cartilage, reducing friction to almost zero in a very healthy knee.

• Position the metal implants: The removed cartilage and bone is replaced with metal elements that recreate the surface of the joint. These metal elements could also be cemented or "press-fit" into the bone.
• Resurface the patella: The base of the kneecap is cut and filled with a plastic button.
• Insert a spacer: A medical-grade plastic spacer is inserted between the metal parts to form a sleek gliding surface.
