At puberty three fifths of an inch canbe removed from each. Very often, indeed, disease of the epiphyseal struc-ture modifies or destroys the power of subsequent development, and inevitabledeformity follows. If the leg be slightly flexed, or the joint cavity distended,the apex of the patella corresponds to the articular line of the joint. There are two well-known methods of excision of this joint: 1, the non-subperiosteal, or ordinary; and 2, the subperiosteal method. The former is employed only when the tissues are tooextensively destroyed or diseased to admitof the saving of the periosteum.
