– See: PreOp Planning: – Discussion: – a candidate for HTO should have relatively normal lateral and patellofemoral compartments; – degenerative changes confined to medial compartment should be apparent in x-rays, although minor arthritic changes in lateral compartment or patellofemoral joint are not absolute contraindications – HTO is contraindicated w/ lateral compartment or patellofemoral symptoms … Read more
