Trochlear contact pressures after anteromedialization of the tibial tubercle.

Background: Anteromedialization is recommended for cartilage restoration of patellofemoral defects, with the presumption that it decreases contact pressures across the trochlea. No study has evaluated pressures on the trochlear side of the patellofemoral joint after anteromedialization of the tibial tubercle.

Hypothesis: Anteromedialization of the tibial tubercle decreases contact pressure across the trochlea.
