Results Validity (referenced to radiographs): Each method for all 3 raters yielded very high CCCs for flexion (0.975 to 0.988), and moderate to substantial CCCs for extension angles (0.478 to 0.678). 95% limits of agreement for the mean difference for all paired comparisons were computed. Agreement between raters was assessed using intra-class correlation coefficients (ICCs). Main outcomes: Agreement between methods and within raters was assessed using concordance correlation coefficient (CCCs). Three assessors were assessed for reliability and validity. Knee range of motion was measured radiographically and photographically using a goniometer. Participants: 31 volunteers (13 arthritic and 18 healthy subjects). Setting: Radiology and orthopaedic departments of two teaching hospitals. Methods Design: Methodology study assessing the validity and reliability of one method ('Marker Method') which uses a skin marker over the greater trochanter and another method ('Line of Femur Method') which requires estimation of the line of femur. This study tests the validity and reliability of measuring knee range of motion using goniometry and photographic records. Intra-observer reliability is thought to be satisfactory, but the validity and inter-rater reliability of knee goniometry often demonstrate unacceptable levels of variation. Background The clinimetric properties of knee goniometry are essential to appreciate in light of its extensive use in the orthopaedic and rehabilitative communities.
