Cortisone is a steroid naturally produced in the body during times of stress. Corticosteroid injection therapy involves injecting synthetically produced Cortisone into the knee joint. These injections are used to periodically reduce inflammation and fluid build up in the knee and to substantially reduce pain for up to three months. Corticosteroid injections typically involve only a single session and provide immediate temporary pain relief. Corticosteroid injections are given infrequently, to prevent damage to knee cells in the long term. Common corticosteroids used in knee injection therapy aremethylprednisolone(Medrol) and triamcinolone (Aristocort, Aristospan, Clinacort, Kenalog, Triamcot, Triam-Forte, Triesence)
Hyaluronic Acid Injections
Also known as viscosupplementation, this treatment involves injecting the knee joint and removing some joint fluid while replacing it with healthy joint fluid, providing pain relief and improving mobility in the process. This newly injected joint fluid functions as a gel, actively preventing bones from scraping against each other and providing a cushioning effect. While the cushioning effect provided by viscosupplementation is temporary, the pain relief along with the accompanying reduction of inflammation can last much longer. Viscosupplementation is typically recommended for more long term relief. Depending on the joint fluid used, viscosupplementation can take several weekly sessions to ensure appropriate results. Common types of hyaluronic acid injections include sodium hyaluronate (Euflexxa, Hyalgan, Supartz), high-molecular-weight hyaluronan (Monovisc, Orthovisc), hylan G-F 20 (Synvisc, Synvisc One), and cross-liked hyaluronate (Gel-One). Treatments involving each of these substances can vary the number of sessions necessary and the potential side effects.
Of course it's always important to remember to take preventative measures to prevent long term knee pain. Actions such as prioritizing exercise activities that don't overburden the knees like swimming and staying at a healthy weight all contribute to long term knee care. However, some amount of knee strain is unavoidable and for times when pain becomes a critical problem, knee injection therapy can provide lasting relief.
