Methodology: A comprehensive search for articles was performed through manual and electronic searches using predetermined keywords. Full text articles related to pre-identified outcome measures specifically, pain assessment scales, range of motion measurements, circumference measures, functional performance tests, and the Cincinnati Knee Rating System, were reviewed. Results: A total of 20 articles were included in the review. The outcome measures selected for the study were found to be valid and yielded moderate to high reliability. Conclusion and Recommendations: The outcome measures that were found to be valid and reliable were summarized into an evaluation form with a user's guide that outlines the testing procedures for use in the clinical setting.
