Partial Knee Replacement

Partial Knee Replacement, or Unicompartmental Knee Replacement, is an effective arthroscopic surgical treatment for those experiencing chronic knee pain as a result of arthritic conditions, ligament damage and tissue damage. Partial Knee Replacement is offered when damage to the knee is contained to a single compartment of the knee. If the damage is affecting more than one compartment of the knee, your surgeon may recommend a Total Knee Replacement.

To begin Partial Knee Replacement, one or more small incisions are made around the knee area where the pencil sized cameras and surgical instruments will be inserted. Next, a clear sterile fluid is injected that allows the surgeon to visualize the area in greater detail.

Once the damaged areas have been verified your surgeon will use small shavers to remove the cartilage from the damaged compartment of the knee while the healthy cartilage is left intact. The ends of the femur and tibia (the bones that make up the knee) are then capped with a metal covering.   A spacer is placed in the caps to allow for a smooth and natural range of motion.
