Degenerative joint disease (DJD), or osteoarthritis (OA), is a common problem in not just the older patients but increasingly in the younger population, in those who have performed over many years strenuous physical activities such as certain types of occupation and sports.
Joint injections are of main twoly types. One is with cortisone, which reduces joint inflammation, most commonly in the hips, knees and shoulders.
The second type is with hyaluronan injections — also called viscosupplementation. These medications work like a cushioning fluid in the joints – to reduce the ‘bone on bone’ bumping and grinding in the knees.
Both steroid and hyaluronan injections have their separate benefits and limitations. They can be safely performed by experienced practitioners including some primary care physicians.
