Which factors predict the long-term outcome in chronic patellofemoral pain syndrome? A 7-yr prospective follow-up study

Abstract

The results of the current and our previous (15) observations support the concept that restoration of good quadriceps strength and function to the affected extremity is important for good recovery of the patient. In addition, negative findings in the clinical tests of patellar pain and crepitation, nonappearance of bilateral symptoms during the follow-up, low body height, and young age are associated with good long-term outcome.
