Hungerford and Barry analyze the biomechanics of the patellofemoral joint using static force equations, cadaveric contact area measurements, and experimental quadriceps force curves to explain how the joint manages load across the flexion arc — and why certain rehabilitation exercises cause harm.
When managing patellofemoral pain, avoid prescribing resistance knee-extension exercises — even light weights generate supraphysiologic contact stress as the knee approaches full extension.
Substitute straight leg raises, which load the quadriceps maximally while producing zero patellofemoral compression.
