“…Baseline and follow-up radiographs were graded as KL 0-no radiographic features of OA, 1-doubtful JSN, 2-definite osteophytes and possible JSN, 3-multiple osteophytes, definite JSN and sclerosis, and 4-large osteophytes, marked JSN, severe sclerosis and deformity [21]. Each radiograph was similarly graded on the basis of the OARSI JSN classification as none, mild, moderate, or severe (0-3, respectively) [22,23]. Progression in either KL or OARSI score was defined as any increase from baseline value.…”

Objectives To characterize the morphology and imaging findings of femoral head subchondral insufficiency fractures (SIF), and to investigate clinical outcomes in relation to imaging findings. Methods Fifty-one patients with hip/pelvis magnetic resonance (MR) images and typical SIF characteristics were identified and reviewed by two radiologists. Thirty-five patients had follow-up documentation allowing assessment of clinical outcome. Subgroup comparisons were performed using regression models adjusted for age and body mass index. Results SIF were frequently associated with cartilage loss (35/ 47, 74.5 %), effusion (33/42, 78.6 %), synovitis (29/44, 66 %), and bone marrow oedema pattern (BMEP) (average crosssectional area 885.7±730.2 mm 2 ). Total hip arthroplasty (THA) was required in 16/35 patients, at an average of 6 months post-MRI. Compared to the THA cohort, the non-THA group had significantly (p<0.05) smaller overlying cartilage defect size (10 mm vs. 29 mm), smaller band length ratio and fracture diameters, and greater incidence of parallel fracture morphology (p<0.05). Male gender and increased age were significantly associated with progression, p<0.05.Conclusions SIF were associated with synovitis, cartilage loss, effusion, and BMEP. Male gender and increased age had a significant association with progression to THA, as did band length ratio, fracture diameter, cartilage defect size, and fracture deformity/morphology.

“…The Croft grade had the weakest associations with clinical symptoms of hip OA [5] . Construct validity was assessed between the pain and function and X-ray stages in hip OA patients by Gossec et al They concluded that KL, OARSI stages and categorization of JSW all have similar predictive and construct validity, it appears that categorical JSW is more reproducible and more sensitive to change and may be the preferred method to evaluate structural severity in hip OA clinical trials [7] . As a conclusion the measurement of minimal joint space width (JSW) was generally acknowledged as the cardinal individual feature in assessment of radiological hip OA and for monitoring of progression of degeneration over time and correlate with clinical status of hip OA patients [16,17] .…”

“…Most studies have used radiological changes to define hip OA [2,3] . Although there are various definitions of hip OA, cross-sectional association with symptoms which represent construct validity of these definitions has rarely been studied in hip OA and the results are conflicting [4][5][6][7] . Radiographic variables, particularly minimal joint space width measurement (JSW), are considered the most appropriate structural with Spearman correlation test.…”

AIM:To analyze the association between the severity of pain and individual radiographic features and global radiographic indexes in hip osteoarthritis (OA). MATERIALS AND METHODS:Forty-five consecutive patients who attended to our outpatient clinic with hip pain diagnosed as hip OA according to American College of Rheumatology (ACR) criteria were recruited for the study. Anteroposterior pelvic radiographs were obtained in all patients. Radiographs were read blindly and evaluated using Croft index, Lane index, individual radiographic features (IRF) of Lane index and Croft's measurement of the "minimal joint space" (MJS) and Kellgren-Lawrence grading by a radiologist. After radiographic evaluation Kellgren Lawrence grade 1 patients were excluded from the study and 38 patients with Kelgren Lawrence grade 2-4 hip OA patients were statistically analyzed. Correlation between the severity of pain evaluated by visual analog scale (VAS) and radiographic findings were statistically analyzed with Spearman correlation test. Linear regression analyses (stepwise method) were used to investigate associations between severity of pain and radiographic findings. JSN and osteophyte grading according to Lane index, MJS, MJS<2.5 mm and global indexes (KL,Croft,Lane) were chosen as independent variables in linear regression analyses. RESULTS:Mean age of patients was 60.76+13 years. 38 patients had Kellgren Lawrence grade 2-4 hip osteoarthritis. Joint space narrowing (JSN) grading according to Lane index (r =0.32 and p=0.05) and minimal joint space measurement <2.5 mm according to Croft index (r = -0.33 and p=0.04) showed correlation with severity of pain. No correlation was observed between osteophyte grading, sclerosis, cyst, deformity and global indexes and severity of pain (p> 0.05). Applying logistic regression analyses, only reduced minimum joint space (MJS) (cut off value set at 2.5 mm) was found to be significantly associated to the severity of pain (p=0.002.) CONCLUSION: Quantitative measurement and grading of joint space narrowing showed correlation with severity of pain in hip osteoarthritis patients. It is observed that the radiographic finding that is related to the severity of pain in hip OA was MJS< 2.5 mm. This finding should be confirmed with further studies of larger sample size of patients with different radiographic severity.

“…When compared with the major categorical systems for hip osteoarthritis, such as the Kellgren and Lawrence [2] system and Osteoarthritis Research Society International stages [3], JSW showed higher sensitivity for advancement of osteoarthritis [4]. Recent advancement of MR imaging allows three-dimensional morphological measurement of hip articular cartilage directly [5,6].…”

Comparative evaluation of three semi-quantitative radiographic grading techniques for hip osteoarthritis in terms of validity and reproducibility in 1404 radiographs: report of the OARSI-OMERACT Task Force

Abstract: Categorical JSW has similar validity and higher sensitivity to change than the other categorical scoring techniques in hip OA. These results indicate categorical JSW may be the preferred method to evaluate structural severity in hip OA clinical trials.
