What you can expect

By Mayo Clinic Staff

During the procedure

After you're anesthetized, your surgeon will make an incision over the area of bone to be remodeled. Depending on the location of the arthritis damage within your knee, the surgery may involve your shinbone or your thighbone. The most common form of knee osteotomy involves the shinbone.

In the simplest variety of knee osteotomy, your surgeon removes a wedge of bone. The cut edges of the bone are brought together and fastened in place with metal hardware. Another option is to cut the shinbone or thighbone and insert a wedge of bone, either from your pelvis or a bone bank. Metal hardware secures the pieces.

After the procedure

Depending on the complexity of the surgery and how well you recover, you might stay in the hospital for a night or two. You'll need to use crutches for approximately two months for your bone to heal properly. Rehabilitation may take as long as six months and will include exercises designed to:

  • Strengthen your thigh muscles (quadriceps)
  • Increase your knee's range of motion
  • Improve your balance

Occasionally a brace is used to support the bone while it heals.
