Tendonitis vs. Tendinosis
Why won’t that tendinitis heal?
At some time in our life we all face or know someone who has faced some injury labeled as an “-itis”. Thereare a few
common maladies that seem to creep into our everyday vocabulary. These are usually labeled along with an
accompanying sport such as; Runner’s knee, Tennis elbow, golfer’s elbow, or swimmer’s shoulder. A couple of
these seem to defy the sport naming rule and stand alone, such as Achilles tendonitis and plantar fasciitis. These
will strike a resonant cord with you who have felt the sting of these particular pains as they are often difficult to
resolve. This difficulty has often been due to the fact that the pain we are experiencing may not in fact be an
“itis” at all. It may in fact be something not as simple as a structure that is simply inflamed or irritated but
has actually become weakened and intolerant of activity. We now are experiencing the effects of an “osis”.
How can you tell and what exactly is different? Most of the time pain is experienced after a single bout of
over exertion or a rapid increase in volume of activity. This situation will irritate tissue and the classic “itis” is
experienced. We don’t give this too much thought because it usually last about 2 weeks and then resolves.
Once this pain continues beyond two weeks the body takes notice and we see tissue changes start to occur. The change is
basically a failure of the body to build connective tissue faster than it is breaking down.
For those of you familiar with old TV shows, I like to think of Lucille Ball in the candy factory episode. She is supposed to
be wrapping candy as it comes down the conveyor belt. The belt speeds up and she loses control so the candy is going
everywhere except where it is supposed to be going. The system is not working so something has to change in order for
poor Lucy to get back on track. Classic treatment for an “itis” is Rest, Ice, Compression, and Elevation. Your doctor may
also recommend anti-inflammatory medication. If this is done the tissue will calm down and activity can be
re-introduced. Classic treatments for an “osis” are a little more complex. The trick is to re-fortify the tissue to make it
more tolerant of activity. The problem is that the tissue is weakened and will often react with a painful response. This
response is often NOT a result of inflammation but instead because of the changes in the tissue. One of the characteristics
of an “osis” is that it is recalcitrant to treatment. Discussion with your health care providershould include the different
options available for your individual diagnosis. The role of a physical therapy program is to provide specific systematic
progressive overload, muscular endurance, and speed of exercise to improve muscular power. These exercises should be
performed in sound biomechanical patterns to avoid secondary stresses (i.e. avoid “my ankle feels better but my knee
sure hurts now”).
Call your health care provider and get the help you need to teat these “all-too-common” ache and pains. Move Well!
