Cortisone shot in knee can be used to soothe knee pain resulting from various causes. This includes tendonitis, bursitis, gout, cartilage tears and arthritis. It is one of the best ways to relieve pain and recover function. However, a cortisone shot in knee is not a permanent cure.
Since the relief is just temporary patients should be even more cautious with their knee so as to not injure it further. Long term and repeated use of cortisone will cause bone loss, weakening of tendons, and cartilage loss in the knee joint. This is why doctors only allow a maximum of three injections per year.
