Surgery is often recommended for treatment of cerebral palsy when contractures are severe enough to cause movement problems. In the operating room, surgeons an lengthen muscles and tendons that are proportionately too short.

Because lengthening a muscle makes it weaker, surgery for contractures is usually followed by months of recovery.

For this reason, doctors try to fix all of the affected muscles at once when it is possible or, if more than one surgical procedure is unavoidable, they may try to schedule operations close together.
