Project Arthritis Recovering Quality of Life Through Education - Hip
Introduction: One in four people are at risk of developing symptomatic hip OAH. Perhaps the greatest potential for improvement in OAH treatment is to approach the early stages of pathology, since total hip arthroplasty was considered 20th century surgery, with high cost-effectiveness in patients who are not responding to clinical treatment. Joint lavage with saline shows significant pain relief in patients with knee and hip OA. In addition, when the saline solution is injected under pressure, it can generate a hydraulic distension of the capsule, increasing the joint amplitude and increasing the effect of drugs injected after washing. Injection of corticosteroids (CS) is recognized for improving the effects of joint washing, pain and even viscosupplementation. In the investigators experience, lavage and infiltration of triamcinolone, lidocaine with or without hyaluronic acid led to subjective-functional improvement and range of motion of the majority of patients with OAH grades 2 and 3 of K & L undergoing the procedure. Intra-articular injection of hyaluronic acid (HA) is analgesic and anti-inflammatory in addition to promoting better distribution of forces, lowering pressure by weight and recovering the viscoelastic properties of synovial fluid, i.e., mechanical effects. In previous studies by the investigators, the addition of hilano to the lavage and injection of triamcinolone and local anesthetic led to gains in joint amplitude that were maintained over a year. Objective: To evaluate whether lavage followed by injection of triamcinolone, ropivacaine and 4 mL of hylan in the affected joint (Hilano) improves function, range of motion, pain, quality of life and muscle strength in patients with OAH in the early stages METHODS: 48 patients from the public network attended by the Orthopedics and Traumatology Institute of the General Hospital of the Medical School of the University of São Paulo, already identified with bilateral OA of the hip submitted to THR in one limb and the other limb presenting OA mild or moderate with indication of non-surgical treatment will be submitted to lavage, saline infiltration and CS (control group) or lavage, saline infiltration, CS and Hilano. Patients will be assessed at 1, 3, 6 and 12 months after the procedure using standardized questionnaires (WOMAC and Lequesne), quality of life scales (Euroqol-EQ-5D-5L), pain, range of motion and strength using an isokinetic dynamometer.
