ReviewA systematic review of radiographic definitions of foot osteoarthritis in population-based studies.
To identify the methods used in population-based epidemiological studies to diagnose radiographic foot osteoarthritis (OA) and to estimate the population prevalence of radiographic foot OA. ⋯ There are comparatively few studies examining radiographic foot OA. Existing studies mainly focus on the first MTP joint and use the K&L grading system. Future studies are needed to quantify the prevalence of radiographic OA at the different joint complexes within the foot.

Evaluating the responsiveness of the ICOAP following hip or knee replacement.
The Intermittent and Constant Osteoarthritis (OA) Pain (ICOAP) questionnaire evaluates the constructs of 'intermittent'(tm) and 'constant'(tm) pain. Theses are conceptually different from 'pain on activity'(tm) and pain 'intensity'(tm) as measured by the WOMAC and Chronic Pain Grade (CPG), measures commonly used in OA. The purpose of this study was to evaluate the responsiveness of the ICOAP, and different pain constructs in primary total hip (THR) and total knee (TKR) replacement. ⋯ Multi-faceted constructs of pain are effectively relieved through joint replacement and all measures including the ICOAP demonstrated responsiveness.

Loading and knee alignment have significant influence on cartilage MRI T2 in porcine knee joints.
Physiological magnetic resonance imaging (MRI) under loading or knee malalignment conditions has not been thoroughly investigated. We assessed the influence of static loading and knee alignment on T2 (transverse relaxation time) mapping of the knee femoral cartilage of porcine knee joints using a non-metallic pressure device. ⋯ The response of T2 to change in static loading or alignment varied between the medial and lateral cartilages, and among the deep, intermediate, and superficial zones. These T2 changes were significantly related to the contact pressure measurements. Our results indicate that T2 mapping under loading allows non-invasive, biomechanical assessment of site-specific stress distribution in the cartilage.

Multicenter StudyReliability and validity of the Persian version of Foot and Ankle Ability Measure (FAAM) to measure functional limitations in patients with foot and ankle disorders.
To translate the Foot and Ankle Ability Measure (FAAM) into Persian and to evaluate the psychometric properties of the Persian version of FAAM. ⋯ The Persian version of FAAM is a reliable and valid measure to quantify physical functioning in patients with foot and ankle disorders.

Meta AnalysisDoes land-based exercise reduce pain and disability associated with hip osteoarthritis? A meta-analysis of randomized controlled trials.
To determine if clinical guidelines recommending therapeutic exercise for people with hip osteoarthritis (OA) are supported by rigorous scientific evidence. ⋯ Currently there is only silver level evidence (one small RCT) supporting the benefit of land-based therapeutic exercise for people with symptomatic hip OA in terms of reduced pain and improved physical function. The limited number and small sample size of the included RCTs restricts the confidence that can be attributed to these results.
