Pearson correlation coefficients between the shoulder outcome instruments and Short Form\u221236 were less than excellent ( r &lt; .60).

Most of the tested shoulder outcome instruments did not reflect health-related quality of life well and poorly correlated with each other. This meant that the comparison of a given surgical result with different outcome instruments might be of little practical utility. Further prospective and serial studies should be conducted to develop better shoulder outcome instruments that have significant reliability, responsiveness, validity, and correlation with health-related quality of life. A careful combination of outcome instruments might be necessary to compensate the current evaluation systems.<\/jats:p>\n
