Intra-Articular Injection Administration

Introduction

Intra-articular injections are a crucial treatment approach in physical medicine and rehabilitation. They involve the direct administration of pharmacological agents into a joint space to alleviate inflammation, pain, and improve function.

Pharmacological Agents Used

Corticosteroids

Corticosteroids, such as methylprednisolone and triamcinolone, are commonly used to reduce inflammation in conditions like osteoarthritis and rheumatoid arthritis.

Hyaluronic Acid

Hyaluronic acid is injected to supplement joint lubrication, improving mobility and reducing pain in patients with degenerative joint disorders.

Platelet-Rich Plasma (PRP)

PRP therapy utilizes the patient's own platelets to enhance healing and tissue regeneration in osteoarthritis and joint injuries.

Procedure & Administration

• Patient evaluation and informed consent
• Preparation of the injection site with antiseptic solution
• Guided needle placement using ultrasound or fluoroscopy
• Slow administration of the pharmacological agent
• Post-injection monitoring and follow-up care

Benefits & Risks

Intra-articular injections offer rapid symptom relief and functional improvement with minimal invasiveness. However, potential risks include infection, joint pain flare-ups, and systemic effects of injected agents.

Conclusion

Intra-articular injections are an essential therapeutic tool in managing joint disorders and musculoskeletal conditions. Appropriate patient selection and technique ensure optimal benefits while minimizing complications.
