Lavagem articular em osteoartrite de joelhos: um estudo controlado randomizado duplo-cego
Objective: Compare the medium-term effectiveness and tolerance intraarticular injection (IAI) with triamcinolone hexacetonide (TH) associated to joint lavage versus IAI with TH alone in patients with primary osteoarthritis (OA) of the knee. Methods: A randomized, double-blind, controlled study was c...

| Sumario: | Objective: Compare the medium-term effectiveness and tolerance intraarticular injection (IAI) with triamcinolone hexacetonide (TH) associated to joint lavage versus IAI with TH alone in patients with primary osteoarthritis (OA) of the knee. Methods: A randomized, double-blind, controlled study was carried out on 60 patients with primary OA of the knee, with pain in at least one of the knees and Grades II and III on the Kellgren-Lawrence index (KL II and III). Patients were randomized into two intervention groups: JL/TH Group – patients submitted to joint lavage with 0.9% saline solution (1000 ml) followed by a 60-mg injection of TH (3 ml); and TH Group – patients submitted to simulated joint lavage (sham) followed by a 60-mg injection of TH (3 ml). Patients were followed up for 12 weeks by a blinded observer using: visual analogue scale (VAS) for pain at rest and on movement; range of movement; Womac index; Lequesne’s questionnaire; timed 50-foot walk; subjective perception of improvement; Likert scale (0-5) for improvement assessment; the need for non-hormonal anti-inflammatory medication and analgesics; the local side effects. Results: Average age was 63.7 (± 8.59) years; mean duration of disease was 5.69 (± 5.01) years; the KL II/III proportion was 33/27; 88.3% were women and 48.3% were Caucasian. Although both groups demonstrated statistically significant improvement in the intra-group evaluation (except for Likert improvement scale according to the patient and the use of anti-inflammatory drugs), there were no statistically significant differences in the inter-group analysis for any of the variables studied over the 12-week period. In the KL II and III sub-analysis, there was a statistically significant difference regarding joint flexion among patients classified as KL II, favoring the TH group (p=0.03). For the KL III patients there were statistically significant differences favoring the JL/TH group regarding Lequesne score (p=0.021), WOMAC-pain score (p=0.01) and Likert improvement scale according to the patient (p=0.028) and the physician (p=0.034) at eight weeks. Conclusion: The combination of joint lavage and IAI with TH was more effective than IAI with TH alone in the treatment of primary OA of the knee in KL 3 patients. |
