The effect of graft height mismatch on contact pressure following osteochondral grafting: a biomechanical study.

Hypothesis: Incongruity of the articular cartilage following osteochondral transplantation affects surface contact pressure.

Study Design: An 80 N load was applied for 120 seconds to the femoral condyles of 10 swine knees. Contact pressures were measured using Fuji prescale film.
