Hip Outcome Measures

	Merle d'Aubigne Scale Matta JM. JBJS 1996;78A:1632 The range of motion is expressed as the percentage of the value for the normal hip. This is calculated by obtaining a total of the ranges, in degrees, of flexion-extension, abduction, adduction, external rotation, and internal rotation for the injured hip and dividing it by the total for the normal hip. The clinical score is determined by adding the points for pain, walking, and range of motion.
	Harris Hip Score Most commonly used for THA post-op evaluation May have a ceiling effect and not be sensitive enough to detect subtle differences between different total hip bearing surfaces. Riddle, Arhtritis Rheum 2008;59:876 Harris WH, JBJS 1969:51:737
	Musculoskeletal Function Assessment Martin DP, J Orthop Res, 1996;14:173 Normal subjects: mean score 9.26 (range, 0 to 59). (Engelberg R, J Orthop Res, 1999;17:101).
