Journal ArticleDOI
Varus and valgus alignment and incident and progressive knee osteoarthritis
Leena Sharma,Jing Song,Dorothy D. Dunlop,David T. Felson,Cora E. Lewis,Neil A. Segal,James C. Torner,T. Derek V. Cooke,Jean Hietpas,John A. Lynch,Michael C. Nevitt +10 more
TL;DR: In knees with osteoarthritis, varus and valgus alignment each increased the risk of progression in the biomechanically stressed compartment, and Varus but not valGus alignment increased therisk of incident tibiofemoral osteOarthritis.
Journal ArticleDOI
Comparison of fixed-flexion positioning with fluoroscopic semi-flexed positioning for quantifying radiographic joint-space width in the knee: test-retest reproducibility
TL;DR: Fixed-flexion, non-fluoroscopic radiography of the knee can provide reproducible JSW measurement using widely available X-ray equipment and is more feasible for multicenter clinical studies and routine clinical use than are methods that rely on fluoroscopic alignment of the tibial plateau.
Journal ArticleDOI
Presence of MRI-detected joint effusion and synovitis increases the risk of cartilage loss in knees without osteoarthritis at 30-month follow-up: the MOST study
Frank W. Roemer,Ali Guermazi,David T. Felson,Jingbo Niu,Michael C. Nevitt,Michel D. Crema,John A. Lynch,Cora E. Lewis,James C. Torner,Yuqing Zhang +9 more
TL;DR: The findings suggest that effusion synovitis, a reflection of inflammatory activity including joint effusion and synovitic thickening, may play a role in the future development of cartilage lesions in knees without osteoarthritis.
Journal ArticleDOI
Change in MRI-detected subchondral bone marrow lesions is associated with cartilage loss: the MOST Study. A longitudinal multicentre study of knee osteoarthritis
Frank W. Roemer,Ali Guermazi,Muhammad Javaid,John A. Lynch,Jingbo Niu,Yuqing Zhang,David T. Felson,Cora E. Lewis,J.C. Torner,Michael C. Nevitt +9 more
TL;DR: In this article, a logistic regression model was used to assess the association of change in BML status with cartilage loss over 30 months using stable BMLs as the reference group.
Journal ArticleDOI
Micro-computed tomography: a new tool for experimental endodontology.
TL;DR: Micro-computed tomography was shown to be accurate for experimental endodontology and recorded a highly significant correlation between MCT and video images for both external and internal areas.
