Critical Appraisal of Overall Value to the Rheumatology Community Strengths The KOOS has undergone a substantial amount of psychometric testing, largely among populations for whom the scale was intended.

One study has evaluated the test—retest reliability of the ARS, finding adequate reliability for use in groups and individuals Table 1. The variety of validated language translations and methods of administration is a major strength for WOMAC use in research.

Normative values Normative data have been presented by sex and age group How would you rate the function of your knee on a scale of 0 to 10 with 10 being normal, excellent function and 0 being the inability to perform any of your usual daily activities which may include sports? The IKDC has been shown to be responsive to change following surgical interventions, highlighting its usefulness in this patient population.

Administrative burden Approximately 5 minutes to score, using the scoring spreadsheet. Number of items 12 items.

Translated and validated in many languages, including Chinese 68German 69Japanese 70Swedish 71and Thai The TAS is a simple freely available measure of activity level that spans work, sporting, and recreational activities. Manual scoring can be performed easily using the scoring instructions supplied with the questionnaire.


Content Graduated list of activities of daily living, recreation, and competitive sports. Scoring Each possible response to each of the 8 items has been assigned an arbitrary score on an increasing scale.

Limp, support, locking, instability, pain, swelling, stairs, squatting; knee ligament surgery.

Construct validity The ARS has been reported to have moderate to strong correlation with other knee-related scales that measure activity levels, such as the Tegner Activity Score, Cincinnati Frm Ligament Score, and Daniel Score, suggesting good convergent construct validity In patients with mixed quwstionnaire pathologies, the KOS-ADL has demonstrated adequate internal consistency across multiple languages, as well as adequate test—retest reliability for use in groups and individuals Table 1.

Scoring Each question is scored from 0—4.

Large effect sizes have been reported following TKR Administrative burden Less than 5 minutes to score, using the conversion table provided Psychometric Information Method of development Initial item selection was conducted by review of existing patient-reported outcomes e.

Version Although in some circumstances it has been modified slightly to accommodate different populations, the standard TAS remains in its original format. ACL reconstruction, autologous chondrocyte implantation, microfracture, high tibial osteotomy, and total knee replacement.

Ability to detect change The KOOS appears questionnaie be responsive to change in patients with a variety fogm conditions that have been treated with nonsurgical and surgical interventions Table 2.

Licensing and fees required; applicability of function subscale items; redundant items in pain and function subscales Rasch analysis. Critical analysis of knee ligament rating systems. No qusetionnaire input in development; long recall period; missing data; lacking psycho- metric testing in knee OA; aggregate score may mask deficits in 1 domain; multiple versions available.

J Bone Joint Surg Am. Items were generated by survey of patients with knee or hip OA, review of existing questionnaires e.


Measures of Knee Function

The use of patients with knee disorders in both item selection and reduction ensures content validity. However, the lack of patient contribution to the selection and revision of quesstionnaire in the IKDC means that content validity cannot necessarily be assumed.

Caveats and cautions The need to obtain permission and pay licensing fees prior to use may encourage researchers and clinicians to seek alternatives. Patients with knee and hip OA 78 Missing values No instructions on how to handle missing values. Approximately 5 minutes to score, using the scoring spreadsheet. Lysholm scale and WOMAC index were responsive in prospective cohort of young general practice patients.

Recall period for items Previous week. To determine symptoms and functional limitation in usual daily activities caused by various knee pathologies Construct validity was considered adequate if expected correlations were found with existing measures that assess similar convergent construct validity and dissimilar divergent construct validity constructs 7.

If a mark is placed outside a box, the closest box is chosen.

Measures of Knee Function

The outcomes of two knee scoring quesgionnaire in a normal population. Level of sport and work participation; knee ligament injury with Lysholm. Ability to detect change In patients with knee OA, the KOOS-PS shows moderate to large effect sizes following 4 weeks of physical therapy, and moderate effects 4 weeks after intraarticular hyaluronic acid injection Table 2.
