Cortisone injections can reduce inflammation and pain in osteoarthritis but offer temporary relief rather than a cure.
Understanding Cortisone Injections and Osteoarthritis
Osteoarthritis is a chronic joint condition characterized by the breakdown of cartilage, leading to pain, stiffness, and reduced mobility. It primarily affects weight-bearing joints like knees, hips, and spine but can impact any joint. Managing osteoarthritis often involves a combination of lifestyle changes, physical therapy, medications, and sometimes injections.
Cortisone injections are a common treatment option for osteoarthritis. They deliver corticosteroids directly into the affected joint to reduce inflammation. Corticosteroids are synthetic drugs that mimic cortisol, a hormone naturally produced by the adrenal glands. Their powerful anti-inflammatory effects help calm irritated tissues inside the joint.
Despite their widespread use, many wonder: Can cortisone injections help osteoarthritis? The short answer is yes—they can provide significant relief from pain and swelling—but the effects are temporary and vary widely among individuals.
How Cortisone Injections Work in Osteoarthritic Joints
Cortisone injections work by suppressing the immune response that triggers inflammation within the joint. When cartilage wears down in osteoarthritis, it exposes bone surfaces and causes irritation. This irritation leads to swelling as immune cells flood the area, releasing inflammatory chemicals.
Injecting cortisone directly into the joint interrupts this process by inhibiting these chemicals and immune cells from causing further damage or discomfort. It reduces synovial membrane inflammation (the lining of the joint), which is often responsible for stiffness and pain.
The injection typically contains a corticosteroid combined with a local anesthetic to provide immediate numbing while waiting for the steroid’s longer-term effects to kick in. Patients may feel relief within 24 to 72 hours after treatment.
Duration of Relief
The relief provided by cortisone injections is not permanent. Most patients experience symptom improvement lasting from a few weeks up to several months—usually around 3 to 6 months. After that period, inflammation tends to return as the underlying cartilage degeneration continues.
Repeated injections are possible but generally limited due to potential side effects such as joint tissue damage or weakening of tendons if administered too frequently (usually no more than three or four times per year).
Effectiveness: What Does Research Say?
Numerous clinical studies have evaluated cortisone injections’ effectiveness for osteoarthritis pain relief. The consensus shows that these injections do provide short-term benefits but do not alter disease progression.
A landmark study published in The Journal of the American Medical Association compared patients receiving cortisone injections with those given placebo saline shots. Results indicated significant pain reduction at 4 weeks post-injection but no difference at 12 weeks or beyond.
Another meta-analysis pooling data from multiple trials concluded that corticosteroid injections reduce pain more effectively than placebo for up to 3 months, especially in knee osteoarthritis cases. However, their impact on functional improvement (joint movement) was modest.
Joint Specific Outcomes
The success rate of cortisone injections varies depending on which joint is treated:
- Knee: Most studied; patients often report notable pain relief and improved mobility.
- Hip: Relief possible but technically more challenging to administer accurately due to deeper anatomy.
- Shoulder: Useful for reducing inflammation in shoulder osteoarthritis or rotator cuff issues.
- Spine: Epidural steroid injections may help with nerve-related symptoms but less so with pure osteoarthritic pain.
Risks and Side Effects of Cortisone Injections
While generally safe when administered correctly, cortisone injections carry some risks:
- Joint infection: Rare but serious; strict sterile techniques minimize risk.
- Tendon weakening or rupture: Repeated use can degrade tendons around joints.
- Cartilage damage: Some evidence suggests frequent steroid use may accelerate cartilage loss.
- Pain flare: Temporary increase in pain or swelling after injection occurs in about 10-20% of cases.
- Systemic effects: Minimal with localized injection but may include elevated blood sugar levels temporarily—important for diabetic patients.
Patients should discuss their medical history thoroughly with their healthcare provider before proceeding.
Candidacy Considerations
Certain conditions make cortisone injections less advisable:
- If there is an active infection anywhere in the body.
- If there is allergy to corticosteroids or local anesthetics used.
- If multiple previous injections have been given within a short timeframe.
- If underlying blood sugar control issues exist without proper monitoring.
The Injection Procedure: What Patients Can Expect
Cortisone injection procedures are typically quick outpatient treatments performed by rheumatologists, orthopedic surgeons, or sports medicine specialists.
- The skin overlying the joint is cleaned thoroughly with antiseptic solution.
- A local anesthetic numbs the skin and tissues around the injection site.
- A needle is inserted into the joint space using anatomical landmarks or imaging guidance such as ultrasound or fluoroscopy for accuracy.
- The corticosteroid combined with anesthetic is injected slowly into the joint space.
- The needle is withdrawn; pressure applied briefly to prevent bleeding or bruising.
Patients might feel immediate numbness followed by gradual reduction in pain over days. Some rest or limited activity may be recommended post-injection for optimal results.
Cortisone Injections Compared To Other Osteoarthritis Treatments
To better understand where cortisone fits in managing osteoarthritis symptoms, here’s a comparison table highlighting key features against other common treatments:
| Treatment Type | Main Benefit | Main Limitation |
|---|---|---|
| Cortisone Injection | Rapid anti-inflammatory effect; reduces swelling & pain quickly | Temporary relief; potential tissue damage if overused |
| NSAIDs (Oral) | Eases mild-to-moderate pain; easy administration | Long-term use risks stomach ulcers & kidney issues |
| Physical Therapy & Exercise | Improves strength & flexibility; slows progression naturally | Pain may limit participation initially; requires commitment |
| Surgical Joint Replacement | Permanently restores function in severe cases | Surgical risks; long recovery time; not suitable for all ages/conditions |
| Hyaluronic Acid Injection (“Viscosupplementation”) | Lubricates joints; may improve mobility temporarily without steroids’ side effects | Efficacy debated; slower onset compared to steroids; costly treatment courses needed |
The Role of Cortisone Injections in Long-Term Osteoarthritis Management
Cortisone injections serve as an important tool within a broader management plan rather than a standalone cure. They’re best used strategically when flare-ups cause intense symptoms that hinder daily activities despite other treatments.
Doctors often recommend combining these injections with:
- Lifestyle modifications: Weight management reduces stress on joints significantly.
- Regular low-impact exercise: Swimming or cycling maintain muscle strength without aggravating joints.
- Pain relievers like acetaminophen or NSAIDs: For ongoing mild discomfort between flare-ups.
Monitoring frequency and response ensures maximum benefit while minimizing risks associated with repeated steroid exposure.

Frequently Asked Questions
Can cortisone injections help osteoarthritis pain?
Cortisone injections can help osteoarthritis pain by reducing inflammation inside the joint. They often provide noticeable relief from pain and swelling within a few days, making daily activities easier for a limited time.
How long do cortisone injections help osteoarthritis symptoms?
The effects of cortisone injections for osteoarthritis typically last between 3 to 6 months. However, relief duration varies by individual and the severity of joint damage, as the injections do not stop cartilage degeneration.
Are cortisone injections a cure for osteoarthritis?
No, cortisone injections are not a cure for osteoarthritis. They temporarily reduce inflammation and pain but do not repair damaged cartilage or halt disease progression.
Can repeated cortisone injections help osteoarthritis over time?
Repeated cortisone injections can provide ongoing relief but are usually limited to avoid side effects like joint tissue damage or tendon weakening. Doctors generally recommend no more than three injections per year in the same joint.
What should I expect after cortisone injections for osteoarthritis?
After receiving cortisone injections, you may feel numbness initially from the anesthetic. Pain relief usually begins within 24 to 72 hours. Some mild soreness at the injection site is normal but should improve quickly.
Conclusion – Can Cortisone Injections Help Osteoarthritis?
Cortisone injections undeniably help reduce inflammation and ease painful symptoms caused by osteoarthritis—but they do so temporarily without halting cartilage degradation. Their value lies in providing rapid symptom relief during flare-ups when other treatments aren’t enough on their own.
Used judiciously under medical guidance alongside lifestyle changes and physical therapy, cortisone shots remain a powerful option for managing discomfort linked to this degenerative disease. Patients should weigh benefits against risks carefully and maintain realistic expectations about duration and extent of relief.
Ultimately, “Can Cortisone Injections Help Osteoarthritis?” The answer is yes—by offering effective short-term reduction in inflammation and pain—but they’re part of a bigger toolkit rather than a standalone solution for long-term joint health.
