Is Cortisone Injection for Knee Pain Safe?
Yes, cortisone injections are generally safe for knee pain when administered by a qualified professional. These steroid shots reduce inflammation and provide effective pain relief. However, repeated use may increase the risk of infection, joint damage, and changes in blood sugar levels. Therefore, it’s important to consult your doctor to ensure cortisone injections are the right choice for your knee pain and health needs.

How Safe Are Cortisone Injections for Knee Pain?
Cortisone injections provide effective pain relief and reduce inflammation in the knee, but overuse can lead to tendon or ligament weakening. There’s also a small risk of infection and potential effects on the immune system. People with conditions like diabetes or those taking blood thinners may require extra precautions, as these conditions can increase the risk of side effects.
While cortisone injections offer short-term relief, they don’t address the underlying causes of knee pain. Repeated use can also speed up the progression of knee arthritis. For instance, a clinical trial published in JAMA found that patients who received cortisone injections every 12 weeks for two years experienced significantly more cartilage loss compared to those who received saline (a saltwater solution).
Given these risks, especially with long-term use, it’s important to consider alternative treatments that may provide relief while supporting joint health. These options include hyaluronic acid injections, which offer lubrication and cushioning, and platelet-rich plasma (PRP) therapy, which promotes tissue regeneration.
How Do Cortisone Shots Work For Knee Pain?
Cortisone shots work by reducing inflammation in the knee joint. The steroid is injected directly into the affected area, which helps control the immune response and lower the production of inflammatory chemicals. This relieves pain and discomfort caused by arthritis and tendonitis, providing quick, temporary relief.
In addition to reducing inflammation, cortisone injections can improve joint lubrication by altering the viscosity of synovial fluid. This helps the knee move more smoothly, reducing friction and discomfort. The injections may also assist in breaking up scar tissue or adhesions, which further relieves pain and improves mobility. In fact, a study published in NCBI found that cortisone injections resulted in a 22% reduction in knee pain within one week compared to a placebo (a treatment with no active medicine). This quick, measurable relief makes cortisone injections an effective short-term solution for managing knee pain.
Which Conditions Do Steroid Injections Treat?
Steroid injections are commonly used to treat conditions such as arthritis, bursitis, tendonitis, carpal tunnel syndrome, and sciatica. They are also effective for managing joint pain in the knees, shoulders, hips, and elbows, including tennis elbow, golfer’s elbow, and gout.
Beyond these common uses, steroid injections can provide relief for:
- Autoimmune diseases like lupus or inflammatory bowel disease by reducing immune-driven inflammation
- Soft tissue injuries, including plantar fasciitis or labral tears by targeting the affected area for localized pain relief
While steroid injections provide quick pain relief, they are most effective when combined with rehabilitation exercises. Healthy lifestyle changes can also support long-term recovery and help prevent recurrence.
How Many Cortisone Injections Are Safe for Knee Pain?
You can safely get up to 3 to 4 cortisone injections per year in the same knee joint. However, the exact number varies based on your condition and your body’s response to the treatment. Repeated use can increase the risk of joint damage and weakened tendons.
To minimize these risks, it is generally recommended to allow at least three months between cortisone injections. Overusing them can also lead to faster cartilage wear and bone issues, like stress fractures. If you don’t experience significant relief after the first couple of shots, your doctor may suggest alternative treatments. Exploring options like guided exercise programs, weight management, or joint support tools can help protect your knee and maintain its function for the long term.

How Do You Know If a Knee Injection Is Necessary?
A knee injection may be necessary if you experience persistent pain, swelling, or stiffness that doesn’t improve with medications or rehabilitation exercises. In this case, your doctor will assess your symptoms, condition, and medical history to determine whether an injection is the right option for you.
To support this decision, your doctor may use imaging tests such as X-rays or MRIs to assess the internal condition of your knee. These scans can reveal structural problems like cartilage damage, joint inflammation, or fluid buildup, factors that may not respond well to conservative treatments. If these underlying issues are identified, a targeted injection may be recommended to help relieve pain and improve joint function effectively.
Can Cortisone Injections Postpone Knee Surgery?
Yes, cortisone injections can temporarily postpone knee surgery, especially for individuals with knee osteoarthritis. These injections reduce pain and inflammation, providing relief that can delay the need for knee replacement for several months or even years. However, they are not a permanent solution and may not work for everyone.
If cortisone injections are used as part of a strategy to delay surgery, their timing becomes especially important. When given too close to an operation, particularly within three months, they may increase the risk of post-operative infection. To minimize this risk, your doctor will carefully plan the injection schedule to ensure you benefit from symptom relief while still protecting your long-term joint health.
Are There Any Restrictions After Having a Cortisone Shot?
Yes, after a cortisone shot, it’s recommended that you avoid heavy physical activity and exercise for 24 to 48 hours. This allows the injection to settle in and reduce inflammation. You should also avoid massaging the injection site and avoid excessive movement that could strain the treated area.
In addition to rest, make sure to follow these key precautions after your injection:
• Do not drive for the rest of the day
• Avoid hot tubs, saunas, and baths for 48 hours
• Check blood sugar closely if you have diabetes
• Postpone flying or long trips for a few days
At Total Orthopedics & Sports Medicine, we take every measure after your cortisone shot to ensure a smooth recovery and support your return to full function. Book your consultation today.
When Should You Avoid Cortisone Injections?
You should avoid cortisone injections if you have an infection, uncontrolled diabetes, a joint fracture, or have already had several injections in the same area. They’re also not recommended right before surgery or if the skin near the injection site is damaged.
In some situations, cortisone injections may not be the safest option. For example, if you are taking blood thinners, the risk of bleeding at the injection site slightly increases. Similarly, if you have weak bones in or around the joint, as seen in severe osteoporosis, the chance of joint damage may be higher. Cortisone may also affect how your body responds to other treatments, especially if you recently got a vaccine or are taking medicines that lower your immune system.
In addition, if you are pregnant, breastfeeding, or managing severe conditions like liver or kidney disease, your doctor may suggest a different treatment. This is why sharing your complete medical history is important. It helps your doctor decide whether cortisone injections are right for you.

FAQs
Can Cortisone Shots Cause Skin Discoloration?
Yes, cortisone shots can cause skin discoloration at the injection site. This is a known potential side effect of corticosteroid medications. You may notice lighter or darker patches where the medicine was injected. In most cases, the discoloration fades within a few weeks to several months. If it doesn’t go away, it’s best to speak with your orthopedic surgeon or visit your doctor’s office for follow-up.
Is It Safe to Exercise After a Cortisone Shot?
Yes, you can usually exercise after a cortisone shot, but you must give your body some time. Most doctors recommend waiting 24 to 48 hours before returning to normal workouts. Once the local anesthetic wears off, begin with light movements to help reduce pain and swelling. Avoid too much caffeine during this period, as it can put extra stress on your musculoskeletal system.
Do Cortisone Shots Affect Bone Density?
No, a single cortisone injection for knee pain generally does not impact your overall bone density. Unlike oral steroids, corticosteroid injections are localized and carry a lower risk. However, frequent shots over time may weaken nearby bone or tendons at the injection site. That’s why orthopedic surgeons usually limit their use to a few times yearly. Regular follow-ups help protect your musculoskeletal system while managing pain and swelling effectively.
What Are the Side Effects of Cortisone Injections?
Cortisone injections can cause potential side effects such as temporary pain and swelling at the injection site. You might also notice skin discoloration or slight fat loss under the skin. In rare cases, there’s a risk of infection or tendon weakening. If you experience ongoing discomfort or any unusual changes, it’s important to follow up with your doctor to check for complications.
Are Cortisone Injections Safe for Children?
Yes, cortisone injections are considered safe for children when managed by experienced orthopedic surgeons. They are typically used to treat specific inflammatory conditions and are given in carefully measured doses. To make the process more comfortable, doctors often use a local anesthetic to reduce pain and swelling at the injection site. Because the injection targets a specific area, it causes fewer side effects than oral steroids.
How Long Do Cortisone Injections Last?
Cortisone injections usually provide relief from pain and swelling that lasts from a couple of weeks to a few months. Many people start feeling relief within a few weeks as inflammation goes down. However, the duration can vary depending on your underlying condition and overall health. Your doctor will guide you on when it’s safe to get another injection. This helps manage your symptoms while lowering the chance of side effects.
What Is the Success Rate of Cortisone Injections?
Cortisone injections for knee pain provide short-term relief in about 50–80% of cases. Many patients begin to feel better within a few weeks, though results vary from person to person. The outcome often depends on your condition and overall joint health. At Total Orthopedics & Sports Medicine, we combine cortisone shots with guided rehabilitation plans to improve results. This approach can extend pain relief and help delay the need for surgery.
