hip viscosupplementation with hyaluronic acid by ultrasound guidance

 

Hip viscosupplementation

Osteoarthritis of the hip is a disease of high prevalence in the Portuguese population with significant impact on the functionality and quality of life of patients.

There are several options available for the treatment of pain, although its effectiveness and safety remain relative and hip replacement turns out to be often the only solution for pain control and restoration of functionality and quality of life of patients.

An alternative to surgical treatment of osteoarthritis of the hip is the hip viscosupplementation with hyaluronic acid by ultrasound guidance.

Hyaluronic acid is an important component of synovial fluid and cartilage. It is thought to have a protective effect in articular cartilage and soft tissue surfaces of joints by acting as a lubricant and imparting viscoelastic properties to the joint because of its high viscosity. In this disease the amount and the molecular weight of hyaluronic acid are reduced and its protective properties are mostly lost.

Recent studies showed that injection of viscosupplementation compounds into osteoarthritic joints could be an alternative and efficient method for alleviating the symptoms and restoring the biological properties of normal hyaluronic acid.
