Effects of a metalloproteinase inhibitor on osteochondral angiogenesis, chondropathy and pain behavior in a rat model of osteoarthritis.
To investigate the effects of a matrix metalloproteinase (MMP) inhibitor on joint pathology and pain behavior in the rat meniscal transection (MNX) model of osteoarthritis (OA) and evaluate which aspects of structural disease modification contribute to symptom improvement. ⋯ Here we show that treatment with a MMP inhibitor reduces joint damage, osteochondral angiogenesis and behavioral evidence of pain. The association between osteochondral angiogenesis and pain behavior may be explained by perivascular nerve growth or stimulation of subchondral nerves following loss of osteochondral integrity. Our data suggest that targeting angiogenesis may have utility in the treatment of pain associated with structural damage in OA.

Meta AnalysisSymptomatic efficacy and safety of diacerein in the treatment of osteoarthritis: a meta-analysis of randomized placebo-controlled trials.
To estimate the efficacy and safety of diacerein as a pain-reducing agent in the treatment of osteoarthritis (OA), using meta-analysis of published randomized placebo-controlled trials (RCTs). ⋯ Diacerein may be an alternative therapy for OA for patients who cannot take paracetamol or non-steroidal anti-inflammatory drugs (NSAIDs) because of adverse effects or lack of benefit. However, it is associated with increased risk of diarrhoea, and the symptomatic benefit after 6 months remains unknown.

Multicenter StudyThe relation of femoral notch stenosis to ACL tears in persons with knee osteoarthritis.
A significant risk factor for anterior cruciate ligament (ACL) tears in young athletes is a reduced femoral Notch Width Index (NWI). The purpose of this study was to test if persons with knee osteoarthritis (OA) and ACL tears have smaller NWI independent of prior joint injury and osteophyte volume. ⋯ We identified a smaller NWI in participants with knee OA and ACL tears. Further longitudinal investigation is necessary to determine this as an independent risk factor.

Racial differences in osteoarthritis pain and function: potential explanatory factors.
This study examined factors underlying racial differences in pain and function among patients with hip and/or knee osteoarthritis (OA). ⋯ Factors explaining racial differences in pain and function were largely psychological, including arthritis self-efficacy, affect, and use of emotion-focused coping. Self-management and psychological interventions can influence these factors, and greater dissemination among African Americans may be a key step toward reducing racial disparities in pain and function.
