The Pros and Cons of Steroid Injections for Knee Osteoarthritis


Knee osteoarthritis is a common degenerative joint disease that affects millions of people worldwide. The condition is characterized by the progressive wearing away of the cartilage in the knee joint, leading to pain, swelling, stiffness, and impaired movement. One of the treatment options available to manage the symptoms of knee osteoarthritis is steroid injections. This blog post will explore the potential benefits and drawbacks of this treatment approach.

Pros of Steroid Injections for Knee Osteoarthritis

  1. Pain Relief: One of the primary advantages of steroid injections is quick and significant pain relief. Corticosteroids work by reducing inflammation, which is often the cause of the pain experienced by osteoarthritis patients.
  2. Improved Mobility: By alleviating pain and reducing inflammation, steroid injections can help improve mobility in the affected joint, making it easier for patients to participate in physical therapy and engage in daily activities.
  3. Non-Surgical Treatment: For patients who are not good candidates for surgery, or for those who wish to delay or avoid surgery, steroid injections offer a non-invasive treatment option.
  4. Time-Efficient: Steroid injections can be administered quickly during an outpatient visit, and do not require hospitalization or a long recovery period.

Cons of Steroid Injections for Knee Osteoarthritis

  1. Temporary Relief: While steroid injections can provide substantial relief, the effects are usually temporary, ranging from a few weeks to several months. This means patients may require repeated injections over time.
  2. Potential Side Effects: Although generally safe, steroid injections can have side effects. These can include pain and swelling at the injection site, infection, allergic reactions, and changes in skin appearance.
  3. Deterioration of Cartilage: Some research suggests that long-term use of steroid injections may lead to further deterioration of the joint cartilage, potentially worsening the osteoarthritis.
  4. Systemic Effects: Although uncommon, corticosteroids can sometimes enter the bloodstream and cause systemic effects, such as elevated blood sugar levels or bone loss.


Steroid injections can be a valuable tool in the management of knee osteoarthritis symptoms, offering quick and significant relief for many patients. However, they are not without potential drawbacks, including temporary relief and potential side effects. As with any treatment, it’s important for patients to discuss the pros and cons with their healthcare provider to make an informed decision that aligns with their specific needs, lifestyle, and overall health.
