Question
Am 33 year old male.  Years ago, developed kneecap pain and tendinitis from driving I did for a living at the time.  Had a cortizone injection back then.  Also, changed jobs.  Knee pain went away.  However, it really never has felt the same and has felt unstable and out of place almost and does give way once in awhile and fortunately I have caught myself when that has happened.  

I realize I need to do something about that and prevent a serious injury from knee give out.

I have read in many places about eccentric knee exercise and how they have cured kneecap issues.  However, I wonder if my case is different since mine is an injury from repetitive stress injury and not like a sports injury.

Should I try the eccentric exercises?  Also, if I do them, should I use the slant board that I see other people use, or do them flat on the floor?

Or should I get another cortizone shot and a combination of eccentric exercises?

Answer
Hello Jim,

    Tendinitis of the knee is due to tight muscles (usually the quads) putting tension on the tendons causing friction over the joint, muscles, bursa, etc. which leads to tendinitis over time.
You may want to see a Doctor of Chiropractic who specializes in sports/soft tissue injuries.  They will be able to determine adhesions, scar tissue, or tight muscles which may be causing the symptoms.  Myofascial/soft tissue treatment will help break up the adhesions and reduce muscle tension thus taking pressure off the knee.

Have a great day,
Dr. Brendon O'Brien D.C.
