RESUMO
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> â0.05). Both groups exhibited improved WOMAC total and subsets scores throughout the study (p â< â0.001). 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= â0.001, p â< â0.001, and p â< â0.001, respectively) and best effect sizes at 1 year (0.355, 0.651 and 0.770, respectively). IG group lost weight (p â< â0.001) and BMI (p â< â0.01). Both groups exhibited improvements in TUG and FTSST (p â< â0.001) that remained in all evaluations. FTSST results favored the IG, p â= â0.032. Conclusions: An educational program to patients with KOA, short schooling and low income improves clinically important measures of pain and function.
RESUMO
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.
