OBJECTIVE: To determine whether thigh muscle strength differs between symptomatic and asymptomatic knees, and/or different radiographic strata of knee osteoarthritis (KOA). METHODS: Isometric extensor and flexor strength were analyzed in 3,809 Osteoarthritis Initiative participants (2,201 women and 1,608 men) with central radiographic Kellgren/Lawrence (K/L) grade readings. Isometric strength measurements were stratified by radiographic disease status (K/L grades 0, 1, 2, and 3/4) and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain scores...

INTRODUCCIÓN: La viscosuplementación del líquido sinovial mediante la inyección intraarticular (IA) de ácido hialurónico (AH) es un tratamiento sintomático ampliamente utilizado en la artrosis de rodilla (AR). Además de los productos diseñados para realizar inyecciones múltiples (normalmente de 3 a 5 inyecciones, en intervalos de 1 semana), se presta especial atención a los productos de una única inyección, ya que ofrecen ventajas específicas, como son un menor número de visitas al médico y de intervenciones invasivas con sus riesgos asociados...

OBJECTIVE: In 1971 McEwen and colleagues suggested that the radiological changes of classic ankylosing spondylitis (AS), and the changes of the spondylitis associated with inflammatory bowel disease differ in several respects from the radiological features of psoriatic and reactive spondylitis. The findings of this study have never been confirmed. The aim of this study was to replicate the McEwen study comparing films blinded to diagnostic group. METHODS: The study population comprised 91 patients with classic AS, 15 patients with regional enteritis, 16 patients with ulcerative colitis, five patients with sexually acquired reactive arthritis, two with post-dysenteric arthritis, and 34 with psoriatic arthritis...
