where chondromalacia of the patella is resistant to conservative treatment , and where the existence of a crooks ridge can be inferred from the clinical or x-ray findings , then an operative search for such a ridge , with trimming both of the ridge and of the affected area of the patella , offers a more promising surgical solution than other minor operative procedures , and a less drastic solution than patellectomy .
