Hyaluronic acid injections
A hyaluronic acid injection, sometimes called a gel injection, may be discussed for certain joint problems. Dr. Rick Verjans first assesses the cause of your pain and how an injection might fit your treatment plan.
What does hyaluronic acid do in osteoarthritis?
Hyaluronic acid occurs naturally in joint fluid. An injection aims to reduce pain. Effects vary and not everyone benefits. It does not restore lost cartilage. Convincing benefit from routine use in knee osteoarthritis has not been established.
How is it given?
After skin disinfection, the product is injected into the joint, sometimes with ultrasound guidance. The number of injections depends on the product and agreed treatment plan.
Aftercare and possible side effects
Temporary pain or swelling can occur. Infection is rare. Seek prompt medical advice for increasing pain, redness, warmth or fever. You receive individual advice on activity and pain relief.
Cost
The price depends on the product. Ask about the total cost and possible insurance reimbursement in advance. See the practical information and consultation fees.
Common questions
Does a gel injection work immediately?
Not necessarily. If it helps, improvement can take several weeks. Some patients do not improve. Agree when the result will be reviewed.
Is hyaluronic acid the same as Arthrosamid?
No. They are different products. Hyaluronic acid is not a permanent hydrogel like Arthrosamid. Discuss mechanisms, limitations, risks and costs for your knee symptoms. The term “gel injection” does not make treatments interchangeable.
Should I choose a product myself?
Discuss your diagnosis and previous treatment first. The product and number of injections are agreed beforehand. See the practical questions about injection appointments.
Discussing your options
Read about osteoarthritis, PRP and Arthrosamid. Their uses differ and they are not suitable for everyone.
