A @entity1 -based, subjective outcome measure for @entity1347 was developed, pretested, and validated. The development of the outcome measure was completed in four stages: 1) item generation (167 items), 2) item reduction (by surveying 79 @entity1 ), 3) questionnaire formation and pretesting (20 @entity1 ), and 4) reliability, responsiveness, and validity assessment (100 @entity1 ). This disease-specific quality of life measure is a 32-item questionnaire using a 100-mm visual analog scale response format. Face validity was derived from extensive direct @entity1 input. Content validity was determined by consensus among 20 knee surgeons. There was no significant difference on test-retest reliability, with an overall average error of 6%. The outcome measure demonstrated responsiveness to clinical change correctly in 21 of 25 @entity1 (84%). Construct validity was shown by the ability of the questionnaire to measure the full spectrum of disease; scores ranged from 8 to 99 out of a maximum score of 100. The questionnaire was able to distinguish @entity1 who went on to have surgery (average score, 31) from those who would be treated nonoperatively (average score, 79). The quality of life outcome measure for @entity1347 is the first subjective knee scale of its kind to be validated to measure quality of life in @entity1 with @entity1347 .
