The purpose of this paper is to systematically review the literature to determine the reliability and validity of evaluating medio-lateral patellar position. Nine papers including 237 patients (306 knees) were reviewed. The findings of this review suggest that the intra-tester reliability of assessing medio-lateral patellar position is good, but that inter-tester reliability is variable. The criterion validity of this test is at worse moderate. These are based on a limited evidence-base.
