Uni Knee Resurfacing (UniSpacer®)


The UniSpacer® procedure is designed to relieve joint pain without removing healthy bone, delaying the need for a total knee replacement operation.

Knee Inspected and Cleaned

The first part of the procedure may be done arthroscopically through small incisions. The surgeon uses a small video camera to inspect the knee joint. Any rough edges or debris from the damaged meniscus are cleared away. This is called debridement.

Incision Created

The arthroscopic instruments are removed. A small incision is made so the surgeon can prepare the joint for the implant.

Bone Spurs Removed

If there are bone spurs on the femur and tibia, the surgeon will smooth the area. This will keep the joint free of obstruction so the implant can move properly.

Implant Inserted

The metal bearing implant is inserted between the femur and tibia. The implant is not held in place with cement or screws. The ligaments of the joint and the tension of the femur and tibia keep the implant secure.

End of Procedure

The knee joint is tested by flexing and extending the knee through its range of motion. The metal bearing implant is not fixed in place, allowing it to move as the knee moves.
