A tendon is a cord or band of dense,
tough, inelastic, white, fibrous tissue, serving to connect a muscle with a bone. Think Achilles tendon, which attaches
your calf muscle to the heel. Damage or injury to tendons is quite common.
There is two different issues-tendinitis
and tendinosis. One you’ve probably heard of before. The other, probably
not. While they both sound the same, in reality they are worlds apart.
Tendinitis
is, by definition, inflammation of a tendon. Tendinosis on the other hand
is defined as chronic tendinitis without inflammation and implies chronic
tendon degeneration at the cellular level. Basically, one is short-term with
inflammation, the other long-term, without inflammation, though both are caused
typically by overuse. Repetitive strain injury (RSI) goes by
a lot of names – it can also be called tenosynovitis or chronic tendinopathy by
doctors. Don’t let their fancy jargon scare you! It’s kind of simple –
tendinitis happens when you repeat a motion frequently on tight tissues and
when the rate of damage exceeds your body’s natural rate of repair.

Tendinitis, the most popular diagnosis of the two, usually presents with swelling and tenderness at the sight of pain, often accompanied by stiffness, and less often by weakness. Tendinosis presents most often with stiffness, tenderness to the touch, and weakness–almost identical to tendinitis. Recovery of tendinitis lasts anywhere from days to six weeks, a relatively “quick fix.” Tendinosis recovery can last a few short weeks to a couple months or more depending on the level of degeneration. If left untreated, tendinosis often leads to “tear” injuries

Tendinitis
and tendinosis, both, occur most often in the Achilles tendon (ankle), patellar
tendon (knee), proximal hamstring (high hamstring), common extensor tendon
(elbow), and the supraspinatus tendon (shoulder). With both of these problems
being so relatively close, while treatment is vastly different, proper
diagnosis is vital to the recovery process! So which one do you have? Let’s go
to the research.
While
tendinitis is the wildly over-popular diagnosis among general practitioners, it
may not be the case. Most research coming out on this topic is now showing that
at a cellular level, once believed tendinitis actually is, in fact, tendinosis.
According
to Almekinders and Temple, “Most currently practicing general practitioners
were taught, and many still believe, that patients who present with overuse
tendinitis have a largely inflammatory condition and will benefit from
anti-inflammatory medication. Unfortunately this dogma is deeply entrenched. 10
of 11 readily available sports medicine texts specifically recommend
non-steroidal anti-inflammatory drugs despite the lack of clinical evidence.”
In
light of this, chances are that if you have been diagnosed with tendinitis the
diagnosis was incorrect. Furthermore, traditional, conservative treatment, of
such, with the use of anti-inflammatories, corticosteroid injections, and/or
pain medication may have left you worse off long term even though pain may have
dissipated short term. This is because these drugs inhibit collagen repair and
are designed to eliminate inflammation, not regrow tendon. As mentioned above,
treatment of tendinosis should be aimed at restoring tendon function and
strength. Drugs will not help solve the problem! With all this said, while we
cannot assume a tendinitis diagnosis was incorrect, lingering, worsening, or
reoccurrence of pain would suggest that it may in fact be tendinosis. It is
recommended that treatment plans geared toward tendinitis, in these cases, be
re-evaluated.
Tendinitis
is one of the most commonly diagnosed injuries and all too many struggle to
find relief. With the proper diagnosis and treatment plan, it doesn’t have to
be that way!
