Many patients with osteoarthritis or chronic joint pain receive orthopedic injections over several years. A common question follows: does the body get used to them, and is it safe to keep repeating them? The answer depends largely on the type of injection, the spacing between treatments and the evolution of the joint itself.<\/p>\n\n\n\n

Understanding Orthopedic Injection Tolerance<\/h2>\n\n\n\n

Tolerance can mean two things. The first is how well the body accepts a product over repeated treatments, without increasing side effects. The second is whether the injection continues to provide the same relief over time. Both are important when planning long-term treatment.<\/p>\n\n\n\n

How the Body Responds to Repeated Injections<\/h2>\n\n\n\n

With corticosteroids<\/strong>, the anti-inflammatory effect usually remains, but repeated injections at short intervals into the same joint may affect cartilage and surrounding tissue. This is why clinicians limit the number of corticosteroid injections per joint each year.<\/p>\n\n\n\n

With hyaluronic acid viscosupplements<\/strong>, the body does not develop resistance in the usual sense. The product is gradually broken down and eliminated, which is why repeat courses are needed. Products such as SYNVISC\u00ae<\/a>, MONOVISC\u00ae<\/a>, DUROLANE\u00ae<\/a> and ORTHOVISC\u00ae<\/a> are generally well tolerated over successive treatments.<\/p>\n\n\n\n

With combination products<\/strong> such as CINGAL\u00ae<\/a>, spacing follows the precautions for the corticosteroid component.<\/p>\n\n\n\n

With PRP<\/strong>, since the product comes from the patient’s own blood, there is no immune tolerance issue, but the response varies from one person to another.<\/p>\n\n\n\n

What the Evidence Shows<\/h2>\n\n\n\n

Studies on repeated viscosupplementation in knee osteoarthritis have reported that repeated courses are well tolerated and that the benefit can be maintained over several cycles in suitable patients. For corticosteroids, studies have suggested that frequent, repeated intra-articular injections may be associated with greater cartilage loss, which supports the practice of spacing them out. Data on repeated PRP injections remain more limited and vary between protocols.<\/p>\n\n\n\n
