Definition
Osteotomy means to cut the bone to realign it in a better position. Supracondylar refers to the site where the bone is cut. This is on the thigh bone, just above the knee joint. This surgery, is done to achieve a straight knee (or extended knee). After the bone is cut, pins and plates are sometimes used to help hold the bones in place so they will heal in a new ideal position. These are usually removed up to two years after surgery.
The Dotted line represents the site of where Bone is cut. The Arrows and thick line represent The Pin and plates.
Weight Bearing
Non weight bearing for 4-6 weeks.
Plasters
Long leg plaster casts that includes the knee and the foot, keeping the knee straight for 6 weeks.
Orthoses
After plasters are removed, it is common to have knee immobiliser splints or ground reaction force ankle foot orthoses (GRAFOs) to keep the knees straight.
Special Instructions
After the plasters are removed it is best to keep the knee straight to prevent deformities from relapsing. Bending of the knee should not be forced.
Equipment
A wheelchair with a supportive leg board will be needed. You may also need a hoist and other equipment to help with transfers. Please speak to your Occupational Therapist for assistance.
