In a prospective study of 105 arthrotomies for chondromalacia patellae, patella alta or an increased Q angle was found in most of the knees and was considered to be the usual cause of chondromalacia. The chondromalacia on the patella was usually centrally located with extension equally onto the medial and lateral facets. Femoral changes were uncommon. Patellar realignment together with excision of chondromalacic cartilage gave a satisfactory result in 79 per cent of the eighty-seven knees that could be followed.
在一项对105例髌骨软化症关节切开术的前瞻性研究中，发现大多数膝关节存在髌骨高位或Q角增大，被认为是髌骨软化症的常见病因。髌骨上的软骨软化通常位于中央，并同样延伸至内侧和外侧小面。股骨改变不常见。在可随访的87例膝关节中，79%的患者通过髌骨重新排列并切除软骨软化的软骨取得了满意的结果。
