Viscosupplementation - Injected HA restores the viscosity and cushioning of synovial fluid, reducing friction between arthritic joint surfaces and absorbing mechanical shock during movement.
What Is a Hyaluronic Acid Injection?
A hyaluronic acid (HA) injection, also called viscosupplementation or a visco injection, is a non-surgical procedure that restores the natural lubricating properties of synovial fluid in an arthritic joint. HA is a naturally occurring complex sugar molecule present in healthy joint fluid, giving it its viscous, gel-like consistency that allows joint surfaces to move smoothly over each other.
In osteoarthritis, HA in the joint decreases with age and cartilage breakdown, reducing lubrication and cushioning, increasing friction, and contributing to pain and stiffness. Injecting pharmaceutical-grade HA directly into the joint temporarily restores these properties.
- Natural joint-fluid component - HA gives healthy synovial fluid its viscous, gel-like consistency.
- Restored cushioning - Pharmaceutical-grade HA temporarily restores lubrication in the arthritic joint.
- Reduced friction - Better joint-fluid properties allow smoother joint movement.
- Direct joint delivery - Injected directly into the joint under image guidance.
How Does HA Injection Work?
HA injections work through two complementary mechanisms:
Anti-inflammatory effect - HA modulates inflammatory responses that drive osteoarthritis pain, reducing the proteins that sensitise pain receptors in the joint.
HA injections don't repair cartilage or reverse osteoarthritis. They improve the joint's mechanical and inflammatory environment, reducing pain and improving walking tolerance for weeks to months. Molecular weight matters, high-molecular-weight HA formulations are thicker and more viscous, producing the strongest lubricating effect and longer relief. Nivaan uses pharmaceutical-grade, high-molecular-weight HA for all viscosupplementation procedures.
Conditions Treated with HA Injections in Mumbai
Knee - Early to moderate osteoarthritis, post-traumatic pain, and pain limiting walking or stair climbing.
Hip - Hip osteoarthritis pain and groin or lateral hip discomfort from joint degeneration.
Ankle - Ankle joint osteoarthritis from degenerative or post-traumatic causes.
Who Is a Suitable Candidate for HA Injection in Mumbai?
HA injections work best in carefully selected patients. They may be a good option if you have:
Early to moderate osteoarthritis with some joint space remaining
Function-limiting pain affecting walking, stairs, or daily activity
Insufficient relief from physiotherapy or oral anti-inflammatories
A wish to delay or avoid joint replacement surgery, where clinically appropriate
Previous corticosteroid injections that provided only short-term benefit

The HA Injection Procedure, Step by Step
The procedure is minimally invasive, typically taking 15-20 minutes.
Before the procedure:
- Review of your medical history, imaging, and current treatment history
- Continuing to eat and drink normally
- Pausing blood-thinning medications, if relevant, only on medical advice
- Planning for light activity in the 48 hours afterward
What happens during treatment:
- STEP 1Preparation of the site - The skin is cleaned and local anaesthetic applied if needed. Nivaan uses ropivacaine where numbing is required, a less toxic option than lidocaine, which can worsen joint cartilage.
- STEP 2Image-guided needle placement - Under ultrasound or fluoroscopic guidance, a fine needle is directed accurately into the joint space.
- STEP 3Injection - The HA preparation is injected into the joint space; you may feel mild pressure or fullness.
- STEP 4Completion - The needle is removed and a small dressing applied. If joint fluid is present, your specialist may drain it first to relieve pressure and improve HA distribution.
Recovery and Aftercare
You may experience mild soreness, stiffness, or a temporary flare of joint pain for 1-3 days, a normal response. Avoid jogging, heavy lifting, prolonged standing, and contact sports for the first 48-72 hours.
| Time | What to Expect |
|---|---|
| Immediately after | Mild soreness or fullness sensation |
| Days 1-3 | Post-injection discomfort settles; light activity resumed |
| Weeks 2-4 | Progressive improvement in pain and walking tolerance |
| Weeks 4-8 | Meaningful reduction in pain and stiffness |
| Months 2-6 | Sustained relief; physiotherapy consolidates functional gains |
| Month 6+ | Repeat injection considered if relief has reduced |
Benefits, Risks, and Side Effects
Benefits
Non-surgical - No incisions, implants, or hospital admission
Clinically validated - Supported by randomised controlled trials and endorsed by global rheumatology organisations including EULAR
Long-lasting compared with steroids - Typically 6 months of significant relief, versus 4-8 weeks for corticosteroids
Repeatable - A 2018 systematic review found repeated HA injections remained safe and continued reducing pain for more than two years with ongoing treatment
May delay joint replacement - Meaningful relief can allow physiotherapy and activity to continue, slowing progression in appropriate patients
Risks and Side Effects
Injection-site reaction - Mild pain, swelling, or warmth, usually settling within 1-3 days
Temporary stiffness or flare - Normal, generally resolves in 2-5 days
Rare pseudoseptic reaction - Severe pain and swelling appearing up to 3 days after injection requires medical assessment
Rare infection - Minimised by sterile, image-guided technique
Rare allergic reaction - More likely with avian-derived formulations; minimal risk with synthetic laboratory-produced HA
HA Injection vs. Steroid vs. PRP: Which Is Right for You?
| Comparison | HA Injection | Steroid | PRP/GFC |
|---|---|---|---|
| Mechanism | Lubrication and anti-inflammatory | Anti-inflammatory only | Biological repair and anti-inflammatory |
| Onset of relief | 2-4 weeks | 3-7 days | 2-6 weeks |
| Duration of relief | 6 months, sometimes longer | Typically 4-8 weeks | 12-24 months in appropriate patients |
| Number of injections | One or three, one week apart | 1-2 | 1-3, 4-6 weeks apart |
| Cartilage protection | Possible; may reduce joint-space narrowing | No; repeated use may worsen cartilage | Possible in early to moderate OA |
| Best for | Moderate OA with persistent pain | Acute pain flare | Early to moderate OA or tendon/ligament injury |
Nivaan specialist will recommend the correct option, or a combination, based on your joint staging, symptom pattern, and previous treatment history.
Results and Number of Sessions
Most patients notice meaningful improvement within 2-4 weeks, with full benefit building over 6-8 weeks. A 2023 clinical study found that a majority of patients receiving a single high-concentration HA injection achieved at least 50% improvement in pain, stiffness, and walking ability lasting six months. For deeper or more established OA, a course of three injections spaced one week apart produces more sustained results than a single injection.
Responses vary. Patients with severe, bone-on-bone joint destruction, or those with advanced disease, may show lesser improvement. A repeat course at 6 months is appropriate for patients who experienced good relief initially.
HA Injection Cost Considerations in Mumbai
Cost depends on the specific HA formulation used (single high-concentration injection vs. a three-injection course), the joint being treated, and whether imaging guidance and any joint aspiration are included. Since HA typically requires either one or three sessions rather than an ongoing course, it's worth asking upfront exactly how many sessions your specific case will need, rather than assuming a single-injection quote covers your full treatment.
Why Choose Nivaan Care for HA Injection in Mumbai?
| HA Injection | Nivaan Care | Standard HA Injection |
|---|---|---|
| Who performs it | Interventional pain specialist under image guidance | GP or clinic, may not use guidance |
| Diagnosis | Joint staged with imaging before treatment | Often symptom-based |
| Image guidance | Always ultrasound or fluoroscopy | Often absent; blind injection reduces accuracy |
| Local anaesthetic | Ropivacaine, less toxic than lidocaine | May use lidocaine, which can worsen cartilage |
| Rehabilitation | Personalised physiotherapy plan post-injection | None |
| Follow-up care | Ongoing, structured recovery monitoring | Rarely structured |
Frequently Asked Questions
Steroid injections provide faster onset (3-7 days) but shorter duration (4-8 weeks) and can worsen cartilage with repeated use. HA takes longer to work (2-4 weeks) but lasts significantly longer (6 months) without cartilage damage.
Most patients receive either a single high-concentration injection or a course of three injections spaced one week apart, depending on the formulation used.
Mild discomfort is typical. The area is numbed with local anaesthetic beforehand, so most patients feel only mild pressure. Post-injection soreness for 1-3 days is common.
Yes, HA injections are offered as part of Nivaan Care's non-surgical, interventional pain management approach for patients in Mumbai.
For moderate knee OA, HA injections can significantly delay the need for knee replacement by maintaining function and reducing pain. They don't reverse structural joint damage and aren't a permanent solution for severe, bone-on-bone OA.
