How often cortisone injections are given varies based on the reason for the injection. This is determined on a case-by-case basis by the health care practitioner. If a single cortisone injection is curative, then further injections are unnecessary. Sometimes, a series of injections might be necessary; for example, cortisone injections for a trigger finger may be given every three weeks, to a maximum of three times in one affected finger. In other instances, such as knee osteoarthritis, a second cortisone injection may be given approximately three months after the first injection, but the injections are not generally continued on a regular basis.
1) Bursitis: Bursa are small fluid filled sacs that sit between bones and soft tissues to reduce friction. If there is excessive friction on them, they get inflamed. You tend to get pockets of swelling rather than general swelling of the whole knee. Swelling in front of the knee cap of usually caused by Pre-Patellar Bursitis, aka Housemaids Knee. Swelling behind the knee, often like a squashy orange, is usually due to Popliteal Bursitis, aka Bakers Cyst . Swelling on the inner side of the knee may be due to Pes Anserine Bursitis .

This is exactly what happened to me. I had perfectly healthy 18 year old cartilage in my 50s. I went to my orthopedic doctor for a patellar tracking problem in both knees that could be corrected with simple exercise. But in the meantime my doctor gave me many cortisone injections. 2 years later I was bone on bone. I was and am still absolutely horrified as I have no knee damage history. I became a cripple overnight. I pursued legal action against the drug company who makes the cortisone but it couldn’t be proven unfortunately. Regenexx has helped tremendously to get my life back! I am back to hiking 3 days a week. Thank you Regenexx. You are a God send!!
