Ankle Distraction Arthroplasty

Ankle distraction arthroplasty is a procedure used to treat ankle arthritis, focusing on joint restoration. It is a minimally invasive surgery that relies on the use of external fixation to pull the joint surfaces apart. An external fixator, or “frame,” is a scaffolding assembled around the leg and surgically applied to the ankle.


You will be encouraged to walk on the operated leg twice a day under the guidance of a physical therapist. Oral pain medication will also be given to you that can be taken as needed.

The frame will be worn for 10 weeks to allow for the slow process of tissue growth in the joint to be completed. The frame will then be removed in the operating room under sedation, and a walking boot will be put on the foot.
