Why Cortisone Is Often the First Option
Corticosteroid injections, commonly referred to as cortisone shots, are one of the most frequently recommended treatments for knee pain in orthopedic and primary care settings. When a patient presents with knee osteoarthritis, a meniscus issue, or general joint inflammation, a cortisone injection is often the first intervention offered. The reason is straightforward: cortisone is a powerful anti-inflammatory, it can be administered in the office in minutes, and for many patients it provides noticeable pain relief within a few days.
That relief is real, and for patients dealing with significant knee pain, it can be meaningful. The issue is not whether cortisone reduces inflammation and pain in the short term. It does. The issue is what cortisone does not do, and what repeated injections may be doing to the joint over time. Cortisone does not repair cartilage, restore joint structure, or address the mechanical problem causing the pain. It suppresses inflammation temporarily. When it wears off, typically within a few weeks to a few months, the underlying condition remains unchanged and the pain returns.
What the Research Says About Repeated Cortisone Injections
A significant body of peer-reviewed research has raised concerns about the long-term effects of repeated corticosteroid injections on joint health. A 2019 study published in the journal Radiology, conducted by researchers at Boston University, found that patients who received corticosteroid injections in the knee showed accelerated progression of osteoarthritis compared to patients who did not receive them. The study documented increased cartilage loss, subchondral insufficiency fractures, and osteonecrosis, which is the death of bone tissue beneath the cartilage surface.
A follow-up study from the same research group in 2022 reinforced these findings, showing that patients receiving repeat cortisone injections experienced more rapid joint deterioration than those who received hyaluronic acid injections or no injections at all. The corticosteroid appears to be directly toxic to chondrocytes, the cells responsible for maintaining and repairing cartilage. In other words, the injection that makes the knee feel better in the short term may be accelerating the structural breakdown of the joint. For patients receiving cortisone every three to four months on a recurring schedule, this is information worth understanding. The short-term pain relief can mask the progression of the disease, and by the time the cortisone stops providing meaningful relief, the joint may be in considerably worse condition than it would have been without the injections.
How We Approach Knee Pain at Frontier
At Frontier Pain Relief, cortisone injections are a tool we have available, and there are situations where they are clinically appropriate. But they are not our first line of treatment for knee pain, and they are not something we recommend on a recurring schedule as a standalone plan. Our approach starts with conservative care. That means evaluating the patient thoroughly, understanding the structural and functional picture, and building a treatment plan that prioritizes options with the potential to improve the condition rather than just suppress symptoms.
For many patients, that begins with rehabilitation and targeted exercises designed to strengthen the muscles that support the knee, improve range of motion, and reduce the mechanical load on the joint. Lifestyle modifications including weight management and activity adjustments play a significant role in knee outcomes and are part of the conversation. For patients who are candidates, platelet-rich plasma injections and regenerative medicine offer an approach that works with the body's own repair mechanisms rather than against them. These therapies aim to promote tissue healing and reduce inflammation without the cartilage toxicity associated with corticosteroids. When a cortisone injection is indicated, it is used strategically and sparingly, not as a default repeated intervention.
Making an Informed Decision
The purpose of this article is not to discourage anyone from receiving a cortisone injection. There are clinical scenarios where a cortisone injection is the right call, particularly for acute flares or situations where a patient needs short-term relief to participate in rehabilitation. The purpose is to make sure patients have the information they need to make an informed decision about their care, especially when repeat injections are being recommended as an ongoing management strategy.
If you have been receiving cortisone injections in your knee on a regular basis and your pain continues to return or worsen, it is worth asking your provider whether the injections could be contributing to structural changes in the joint, and whether alternative approaches might offer a better long-term outcome. You are not being difficult by asking that question. You are being an informed patient. If you would like a comprehensive evaluation of your knee pain and a treatment plan that considers the full range of conservative, regenerative, and interventional options, our team is available for that conversation.
