What it is
Hyaluronic acid is a component of normal joint fluid. Injectable products are manufactured to supplement the joint environment. Product, dose, number of injections, and approved indications vary.
Where Dr. Yang offers it
- Mainly selected symptomatic knee osteoarthritis
- Selected shoulder or hip arthritis only after careful review of the diagnosis, alternatives, and weaker or unfavourable guideline evidence
- It is not presented as a way to regrow cartilage or reliably delay surgery
What the evidence says
Professional guidance is not uniform. The ACR/Arthritis Foundation guideline conditionally recommends against hyaluronic acid for knee osteoarthritis and strongly recommends against it for hip osteoarthritis. ACR patient information notes that it may provide temporary pain relief. Treatment should therefore be individualized and presented with its uncertainty.
What a procedure may involve
After a consultation and assessment, a suitable injection is usually booked for a separate procedure appointment. Following procedure-specific consent, the product is injected into the joint. Ultrasound guidance is used for most procedures; selected shoulder or knee injections may be performed without ultrasound when clinically appropriate.
Recovery and results
Mild soreness or swelling may occur for a day or two. If benefit occurs, it may build gradually and is temporary. Follow the activity instructions provided for the specific joint and product.
Who may not be a candidate
- Active infection in the joint or overlying skin
- Known allergy or contraindication to the selected product
- A diagnosis for which expected benefit is low
- Medical factors identified during assessment
Risks and uncertainty
Temporary pain, swelling, bleeding, bruising, infection, and a local inflammatory reaction are possible. Severe or worsening pain, fever, or marked swelling after an injection requires prompt medical assessment.

Frequently asked
Is Hyaluronic acid guaranteed to work?
No. Response varies with diagnosis, severity, individual factors, rehabilitation, and—where relevant—the preparation or product used.
Is ultrasound always used?
Dr. Yang uses ultrasound guidance for most procedures. Trigger finger injections and occasional shoulder or knee injections may be performed without ultrasound when clinically appropriate.
Can I book now?
Patients may submit a private MSK assessment request for clinic review. Consultation comes first; a procedure is not guaranteed and is usually a separate visit.
