If osteoarthritis has caused damage on only one side of the knee joint, it can cause structural issues.

This is accomplished by cutting and realigning the tibia to shift the pressure to the healthier side of the joint.

What are the steps in Tibial Osteotomy with Open Wedge?
Before the Surgery
The patient's knee if positioned so that the surgeon has clear access to it. General anesthesia is applied, and the knee area is cleaned and sterilized in preparation for the procedure.
Accessing the Knee
The surgeon makes an incision on the front or inner side of the knee. This allows access to the tibia and knee joint, which the surgeon uses to examine the joint.
Tibia Realignment
The surgeon cuts into the tibia at an angle, separating the two sides to form a wedge-shaped opening, which is then filled with bone graft material. The surgeon then inserts a metal plate, which is attached with surgical screws, to help hold open the wedge during the healing process.
End of Procedure
The surgeon then closes the incisions with surgical staples or sutures. The leg is then placed in a split.
After Surgery
This procedure may require a one to two day hospital stay. During this time, patients will receive physical therapy. Immobilization devices like a knee brace or crutches may be recommended for the patient to use for up to six weeks.
