Atraumatic patellofemoral joint disorders. Long-term results of surgery.
Clinical and radiographic follow-up was done on a group of patients with atraumatic patellofemoral joint disorders who had been treated surgically by realignment of the extensor apparatus at the authors' institution from 1985 to 1989. The preoperative radiographic examination in the 65 patients treated (for a total of 74 realignments) evaluated the following parameters: sulcus angle, Insall-Salvati index, and congruence angle. The 46 patients who returned for follow-up (after an average of 2 years and 3 months) were evaluated clinically according to a classification system proposed by the authors which is based on objective clinical data and a multi-factorial assessment of pain. Moreover, radiographic follow-up of the same 46 patients made it possible to quantify the degree of realignment achieved with each type of surgical technique. The clinical and radiographic data made it possible to determine more precise indications for each type of surgical procedure in relation to the disease involved, using a correct diagnostic approach and making a thorough evaluation of the clinical, anatomical and pathological features.
