Brief Summary

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.

Detailed Description

Hip OA (OAH) is less frequent than that of the hand and knee OA. One in four people have the risk of developing symptomatic OA of the hip.

Most guidelines for OAQ treatment combine recommendations for the treatment of knee and hip OA although OAH has specific etiopathogenic characteristics with its implications for individual therapeutic approaches.

Perhaps the greatest potential for improvement in OAH treatment is to approach the early stages of pathology, since total hip arthroplasty was considered to be 20th-century surgery with high cost-effectiveness in patients who are not responding to the clinical treatment of OA.

Measures that decrease inflammation and release capsular retraction leading to symptoms of pain and restriction of joint amplitude may improve the quality of life of these patients in the earliest stages of the disease.

Joint lavage with saline shows significant relief of pain in patients with knee and hip OA, probably by intra-articular removal of debris and factors that cause irritation and inflammation. 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 viscossuplementation.

In our experience, lavage and infiltration of triamcinolone, lidocaine with or without hyaluronic acid led to subjective-functional improvement and range of motion of most patients with OAH grades 2 and 3 of Kellgren and Lawrence undergoing the procedure.

The viscossuplementation of the hip has not yet been established in regard to type, dose, indication or frequency, and the number of existing jobs is relatively small in relation to those performed on knee osteoarthritis (OAK). 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. Its prolonged effect is explained by the action of hyaluronic acid on the CD44 receptors of synoviocytes and by the reduction of activated serum T cell levels. In our experience, 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.

Thus, the investigators developed a study to improve the range of motion and the function of patients with mild to moderate OA of the hip through lavage with physiological saline and hydraulic distension comparing to lavage, hydraulic distension and CS injection, anesthetic and a dose of 4mL of G-F20 hilano.
