Treatment Outcomes for Ankle Arthritis

Subjects will come into motion analysis laboratory at the VA Puget Sound Health Care System. A standard set of body measurements will be taken using calipers, a measuring tape, and a scale (for example height, weight, leg length, foot length, etc). The investigators will then attach small reflective markers to the body using double-sided tape and ask the participants to walk several times as the motion of each marker is recorded by infrared cameras.
