Improved function and strength in patients with knee osteoarthritis as a result of adding a two-day educational program to usual care. Prospective randomized trial.

Objective: The primary aim was to quantify the improvements on function and pain of patients with knee osteoarthritis (KOA), short education and low income by a two-day self-management program. Secondary aims were verifying if the program improves clinically relevant measures of weight and strength. Design: A prospective randomized clinical trial was conducted in a tertiary hospital in Brazil with 191 patients with Kellgren & Lawrence grades II and III KOA who were allocated to two groups: control (usual care- CG) and intervention (usual care and two days of an OA self-management program with a multiprofessional team - IG). Western Ontario and McMaster Universities Index (WOMAC), weight, body mass index (BMI), Timed up and go (TUG) and five Times Sit to Stand Test (FTSST) were assessed at baseline, six, 12 and 24 months. Results: Groups were similar at baseline (p â€‹> â€‹0.05). Both groups exhibited improved WOMAC total and subsets scores throughout the study (p â€‹< â€‹0.001). However, only IG improved WOMAC total and subsets in all follow-ups above 20% (minimally clinically important difference), with differences in WOMAC pain, function and total scores (p â€‹= â€‹0.001, p â€‹< â€‹0.001, and p â€‹< â€‹0.001, respectively) and best effect sizes at 1 year (0.355, 0.651 and 0.770, respectively). IG group lost weight (p â€‹< â€‹0.001) and BMI (p â€‹< â€‹0.01). Both groups exhibited improvements in TUG and FTSST (p â€‹< â€‹0.001) that remained in all evaluations. FTSST results favored the IG, p â€‹= â€‹0.032. Conclusions: An educational program to patients with KOA, short schooling and low income improves clinically important measures of pain and function.

Joint lavage followed by viscosupplementation and triamcinolone in patients with severe haemophilic arthropathy: objective functional results.

INTRODUCTION: Viscosupplementation can improve function in haemophilia patients. Viscosupplementation results can be improved by prior joint lavage and triamcinolone administration. AIM: To objectively assess whether viscosupplementation and associated triamcinolone use in patients with severe haemophilic arthropathy following joint lavage improves force and balance and reduces bleeding events. METHODS: Fourteen patients with haemophilic knee arthritis with and without the involvement of other joints underwent joint lavage and subsequent injections of Hylan G-F20 and triamcinolone into all affected joints. Patients were evaluated with NeuroCom® force and balance platforms using the step-up-and-over task (STP), sit-to-stand test (STS), one-leg stance (UNI) and weight-bearing squat (WBS) at baseline and at 1, 3, 6 and 12 months after the procedure. Bleeding events in the year prior to and the year after the procedure were analysed. RESULTS: Sixteen knees, 15 ankles, eight elbows and one shoulder were treated. The STP results indicated improvements in the lift-up indices (right leg) at all time points evaluated (P = 0.03). The STS results revealed coupled improvement in weight transfer and the rising index for up to a year (P = 0.02). Balance (UNI) with eyes open or closed improved in all evaluations. The WBS results revealed improvements at all degrees of flexion (0, P = 0.003; 30°, P = 0.001; 60°, P < 0.001 and 90°, P < 0.001). The numbers of total and traumatic bleeding events were reduced (P = 0.04). CONCLUSION: Joint lavage followed by injections of triamcinolone and Hylan G-F20 improved balance, function and bleeding events in severe haemophilic arthropathy patients.

The OA Trial Bank: meta-analysis of individual patient data from knee and hip osteoarthritis trials show that patients with severe pain exhibit greater benefit from intra-articular glucocorticoids.

OBJECTIVE: To evaluate the efficacy of intra-articular (IA) glucocorticoids for knee or hip osteoarthritis (OA) in specific subgroups of patients with severe pain and inflammatory signs using individual patient data (IPD) from existing trials. DESIGN: Randomized trials evaluating one or more IA glucocorticoid preparation in patients with knee or hip OA, published from 1995 up to June 2012 were selected from the literature. IPD obtained from original trials included patient and disease characteristics and outcomes measured. The primary outcome was pain severity at short-term follow-up (up to 4 weeks). The subgroup factors assessed included severe pain (≥70 points, 0-100 scale) and signs of inflammation (dichotomized in present or not) at baseline. Multilevel regression analyses were applied to estimate the magnitude of the effects in the subgroups with the individuals nested within each study. RESULTS: Seven out of 43 published randomized clinical trials (n = 620) were included. Patients with severe baseline pain had a significantly larger reduction in short-term pain, but not in mid- and long-term pain, compared to those with less severe pain at baseline (Mean Difference 13.91; 95% Confidence Interval 1.50-26.31) when receiving IA glucocorticoid injection compared to placebo. No statistical significant interaction effects were found between inflammatory signs and IA glucocorticoid injections compared to placebo and to tidal irrigation at all follow-up points. CONCLUSIONS: This IPD meta-analysis demonstrates that patients with severe knee pain at baseline derive more benefit from IA glucocorticoid injection at short-term follow-up than those with less severe pain at baseline.
