OBJECTIVES To evaluate the psychometric properties of the OARSI-OMERACT questionnaires in comparison to the existing validated scales. METHODS Consecutive hip or knee osteoarthritis patients consulting in an orthopedic department were enrolled in the study. Data collected were pain using the Intermittent and Constant Osteoarthritis Pain (ICOAP), a Numeric Rating Scale (NRS), the Western Ontar...

BACKGROUND Despite the widely reported success of total joint arthroplasty (TJA) in reducing pain and improving quality of life and function for patients with hip or knee osteoarthritis, rates of TJA use vary widely throughout the United States, with broad disparities based on geographic, racial, and socioeconomic factors. Shared decision-making approaches, which require an exchange of informat...

Despite the near concurrent publication by influential scientific organizations, there are important differences in interpretation of the evidence base and the conclusions derived from the recent Osteoarthritis Research Society International (OARSI) guidelines for the management of knee osteoarthritis, the American College of Rheumatology (ACR) guidelines (concerning also hip and hand osteoarth...

OBJECTIVE To predict the 2-year course of activity limitations in patients with early knee and/or hip osteoarthritis (OA). METHODS The Cohort Hip & Cohort Knee (CHECK) study is a prospective followup study. The CHECK cohort, comprising participants (n = 1,002) with early OA-related knee and/or hip symptoms, was followed for 2 years. Participants completed questionnaires and underwent physical...

A randomized, single-blind, placebo-controlled trial was carried out in 62 patients (30 with osteoarthritis of the hip, 32 with osteoarthritis of the knee) to examine the efficacy of glycosaminoglycan-peptide complex in the treatment of osteoarthritis. Patients received 8-week courses of trial medication, each consisting of intramuscular injections of 3 x 2 ml ampoules per week, alternating wit...

BACKGROUND High body mass index, as well as maintaining this condition for a long period of time, are important risk factors for the development of osteoarthritis. AIM To determine joint pain and osteoarthritis prevalence in patients referred to bariatric surgery. METHODS Morbidly obese patients referred to bariatric surgery responded to the visual analogue pain scale (VAS) and the WOMAC qu...

BACKGROUND There is a lack of data on the long-term outcome of total hip arthroplasty procedures, as assessed by validated tools. METHODS We conducted a follow-up study to evaluate the quality of life and functionality of 250 patients an average of 16 years (range: 11-23 years) after total hip arthroplasty using a validated assessment set including the SF-36 questionnaire, Harris Hip Score, W...

Hip arthroscopy in patients with osteoarthritis has been shown to have suboptimal outcomes. Elevated cytokine concentrations in hip synovial fluid have previously been shown to be associated with cartilage pathology. The purpose of this study was to determine whether a relationship exists between hip synovial fluid cytokine concentration and clinical outcomes at a minimum of 2 years following h...

Although the association between femoroacetabular impingement and osteoarthritis is established, it is not yet clear which hips have the greatest likelihood to progress rapidly to end-stage disease. We investigated the effect of several radiological parameters, each indicative of a structural aspect of the hip joint, on the progression of osteoarthritis. Pairs of plain anteroposterior pelvic ra...
