I will also put my 2 cents worth in.
Rather than look at the glutes as a whole, there is some more research from Steve Saunders that is showing the value of strengthening the Quad Fem (and other deep hip lateral rotators) which stops the femur from internally rotating and also the posterior fibres of Glute Med which when under active cause increased pelvic obliquity or a Trendelenberg gait.
Both those 2 movements cause increased stress through the VL/ITB/Lat Ham which then increases force through patella.
Also look at feet – footwear/? need for orthotics
Really enjoying reading everybody’s input!!
