John Elias and Andrew Cosgarea have reported new and exciting results from their PFF funded research. In a computer model of knees with dysplastic trochleas, they have established that proximal realignment (MPFL reconstruction) creates greater patellofemoral articular loads than tibial tubercle transfer. This important work helps to further clarify the need for distal alignment in controlling patellar instability when the trochlea is flat and there is lateral tracking of the patella. Read More
