Hyaluronic Acid Injections

What Are Hyaluronic Acid Injections?

Hyaluronic acid injections, also known as viscosupplementation, are a treatment designed to relieve pain and improve joint function in patients with osteoarthritis (OA), particularly in the knee. Hyaluronic acid is a naturally occurring substance in synovial fluid that acts as a lubricant and shock absorber, promoting smooth joint movement. In osteoarthritis, the quality of natural hyaluronic acid deteriorates, leading to pain and stiffness. Injecting supplemental hyaluronic acid into the affected joint helps restore lubrication, reducing pain and enhancing mobility. Dr Bassam Moses performs hyaluronic acid injections as part of his treatment approach, offering patients a non-surgical option for managing joint pain.

Who Is Suitable for Hyaluronic Acid Injections?

Hyaluronic acid injections are most beneficial for individuals with mild to moderate osteoarthritis who have not found sufficient relief from conservative treatments. Suitable candidates include:

Patients with knee osteoarthritis, the most commonly treated joint.
Individuals who have not responded to pain medications or topical treatments.
Those seeking to delay knee replacement surgery and manage symptoms non-surgically.
People preferring a non-invasive approach for osteoarthritis pain relief.
Patients without severe joint deformity or extensive cartilage loss.

However, hyaluronic acid injections may not suit individuals with allergies to hyaluronic acid products, active joint infections, or certain medical conditions. Consulting with Dr Moses is essential to determine suitability.

Benefits of Hyaluronic Acid Injections

Pain Relief: Helps reduce pain by improving joint lubrication.
Improved Mobility: Enhances joint function, making movement easier.
Delayed Surgery: May postpone the need for joint replacement procedures.
Minimal Side Effects: Typically causes fewer complications than systemic medications.
Non-Surgical Treatment: Offers a convenient, outpatient procedure with minimal recovery time.

Types of Hyaluronic Acid Injections

Hyaluronic acid injections vary based on molecular weight and frequency of administration:

Single-Injection Formulations: One-time injections that offer convenience, though long-term effectiveness may vary (e.g., Synvisc-One, Durolane, Monovisc).
Multi-injection formulations: Administered weekly over three to five weeks for sustained relief (e.g., Hyalgan, Supartz).
Cross-Linked Hyaluronic Acid: Chemically modified for greater stability and longer-lasting effects (e.g., Synvisc).
Non-Cross-Linked Hyaluronic Acid: Mimics natural hyaluronic acid, offering high biocompatibility (e.g., Euflexxa).

Alternative Options to Hyaluronic Acid Injections

Other treatments for osteoarthritis include:

Pain Medications: NSAIDs (e.g., ibuprofen) and acetaminophen.
Corticosteroid Injections: Reduce inflammation but may have short-term effects and potential side effects.
Physical Therapy: Strengthens muscles around the joint and improves flexibility.
Lifestyle Modifications: Weight management and low-impact activities like swimming and cycling.
Alternative Therapies: Acupuncture, glucosamine, and chondroitin supplements.
Surgical Options: Arthroscopy or total knee replacement for severe cases.

Preparation for Hyaluronic Acid Injections

Before receiving hyaluronic acid injections, patients should:

Consult with Dr Moses to assess medical history and determine suitability.
Pause certain medications, such as blood thinners, if recommended.
Follow pre-procedure instructions, which may include fasting or hydration guidelines.

What Happens During Hyaluronic Acid Injections?

Preparation: The injection site is cleaned, and a local anaesthetic may be applied.
Injection: Hyaluronic acid is injected into the joint space, often under imaging guidance for accuracy.
Post-Procedure: Patients may be monitored briefly before being discharged.

Post-Hyaluronic Acid Injections Expectations and Recovery

After the procedure, patients should:

Apply ice packs to manage any mild swelling or discomfort.
Avoid strenuous activities for at least 48 hours.
Monitor for any unusual symptoms, such as infection or excessive swelling.
Expect gradual pain relief, which typically develops over days to weeks.

Hyaluronic Acid Injections Long-Term Care and Prognosis

Most patients experience pain relief and improved mobility lasting several months to over a year. Regular follow-ups, maintaining a healthy weight, and engaging in low-impact exercises can help prolong the benefits of hyaluronic acid injections.
