Radiographs and MRI scans were assessed for joint space narrowing, subchondral cysts, osteophytes, subchondral sclerosis, Likert osteoarthritis grade (none, mild, moderate, or severe), and T\u00f6nnis grade. MRI scans were also evaluated for bony edema, heterogeneous articular cartilage, and chondral defects. Inter- and intrarater reliabilities were calculated utilizing the Fleiss method with a 95% CI.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>The scans of 50 patients (28 female and 22 male) with a mean age of 42.8 years (SD, 14.2 years; range, 19-70 years) were reviewed. Radiographs revealed fair agreement for joint space narrowing (\u03ba = 0.25 [95% CI, 0.21-0.30]), osteophytes (\u03ba = 0.26 [95% CI, 0.14-0.40]), Likert osteoarthritis grading (\u03ba = 0.33 [95% CI, 0.28-0.37]) and T\u00f6nnis grade (\u03ba = 0.30 [95% CI, 0.26-0.34). Radiographs revealed moderate agreement for subchondral cysts (\u03ba = 0.53 [95% CI, 0.35-0.69]). MRI scans demonstrated poor to fair agreement for joint space narrowing (\u03ba = 0.15 [95% CI, 0.09-0.21]), subchondral sclerosis (\u03ba = 0.27 [0.19-0.34]), heterogeneous articular cartilage (\u03ba = 0.07 [95% CI, 0.00-0.14]), Likert osteoarthritis grade (\u03ba = 0.19 [95% CI, 0.15-0.24]), and T\u00f6nnis grade (\u03ba = 0.20 [95% CI, 0.15-0.24]). MRI scans demonstrated substantial agreement for subchondral cysts (\u03ba = 0.73 [95% CI, 0.63-0.83]). Intrarater reliabilities were statistically improved compared with interrater reliabilities, but no differences were found between radiographs and MRI scans for joint space narrowing, subchondral cysts, osteophytes, osteoarthritis grade, or T\u00f6nnis grade.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>Radiographs and MRI scans had substantial limitations and inconsistency between raters in evaluating common markers of hip osteoarthritis.
