^*PCS and MCS scoring results reported for various orthopaedic procedures and conditions with oblique and RAND recalculations. Recalculations were performed on the basis of reported scale means. Normative values were chosen to match the original study results as closely as possible. If the original study did not calculate summary scores, 1998 U.S. population normative values were used. Values are presented as the mean unless otherwise indicated.

^†Studies included in baseline or preop. measurements.

^‡Studies included in recovery measurements.
