Abstract

The purpose of this prospective study was to identify clinical, pathologic, and roentgenographic factors that might serve as prognosticators for acceptable results after a lateral retinacular release for treatment of patellofemoral pain unresponsive to conservative measures. Fifty-two knees in 45 patients were studied. The data indicated that acceptable results can be expected in patients who have a negative mal-loose sign (no evidence of patellar malalignment or hyperlaxity) or a positive Sage sign (tight lateral parapatellar soft-tissue structures). Poorer results are predictable in patients with patellar hypermobility.
