The value of injectable viscoelastic supplements for joints

Area of Science:

• Orthopedics
• Rheumatology
• Radiology

Background:

• Osteoarthritis (OA) is a common degenerative joint disease.
• Intra-articular viscoelastic supplements are frequently used for symptomatic OA management.
• Musculoskeletal radiologists commonly administer these injections.

Purpose of the Study:

• To provide an overview of intra-articular viscoelastic supplements for osteoarthritis.
• To discuss their mechanism of action, evidence base, and clinical guidelines.
• To describe associated adverse events, particularly for hyaluronic acid.

Main Methods:

• Literature review and synthesis of existing evidence.
• Analysis of major society guidelines on intra-articular treatments.
• Review of reported adverse events associated with hyaluronic acid injections.

Main Results:

• Viscoelastic supplements aim to improve joint lubrication and reduce pain in OA.
• Evidence supporting their efficacy varies, with some guidelines recommending them while others are more cautious.
• Adverse events are generally mild and localized, but potential risks exist.

Conclusions:

• Intra-articular viscoelastic supplements are a treatment option for symptomatic OA.
• Understanding the mechanism, evidence, guidelines, and risks is crucial for informed clinical decision-making.
• Further research may clarify optimal patient selection and long-term outcomes.
