Physical therapy begins in the recovery room immediately after surgery. The patient is connected to a continuous passive motion (CPM) machine that gently flexes and extends the leg for 6 to 8 hours per day for several weeks, often during sleep. The exercises are increased over time until the patient regains full range of motion. Such exercises are believed to speed up cartilage regeneration.

The patient will be told to keep their weight off the affected joint for 6 to 8 weeks. Crutches will be needed.
