General description and treatment of tendinopathies
This is a draft cheat sheet. It is a work in progress and is not finished yet.
Tendon Pathology
Visoelastic tissue |
Loading tendon slowly makes more it more compliant, loading tendon fast engages all fascicles |
Iso-volumetric |
Loading and changing shape of tendon does not change volume as tendons are dense |
Cross-linking |
Slow loading breaks more links than fast loading, therefore tendon stiffer with fast loading |
Tendon stiffness |
Greater compliance or greater stiffness both increase injury risk, muscle should be stronger than tendon is stiff |
Prognosis
True tendinopathy can take months to years to heal |
Types of Load on Tendon
Energy storage and release loads |
Store and release energy, making movements faster and more metabolically efficient |
Compressive loads |
Compressive against bone or bursa, altering range may ease symptoms |
Friction |
Rubbing against the peritendon, may also be affected by an acute blow |
Shear |
Depending on the muscles involved |
|

Tendon Continuum (Jill Cook)
Subjective Markers
Warm up effect |
Localized pain with 1-2 fingers |
Often increase in activity |
Increased pain after a period of rest and is worse the next morning when first getting out of bed |
"Severe" or "sharp" during the early stages and sometimes as a "dull ache" once it has been present for some weeks |
Isometrics act as an analgesic |
Objective Assessment
Observation |
Muscle atrophy, swelling, asymmetry |
Palpation |
Tender to palpate, but we should try not to palpate too much |
AROM/PROM |
May be limited due to pain |
Strength |
May be decreased due to muscle atrophy or pain |
Functional Tests |
Tests that load the tendon to reproduce pain, and other loading tests that load alternative structures |
|
|
Rehabilitation
Patient education = load modification |
Isometric, isotonic and HSR loading in comp to target tissue structure change and muscle strength |
Slow stretch-shortening cycle out of comp to load as spring |
Fast stretch-shortening cycle out of comp to load as spring |
Sports specific exercises out of comp |
Management
Do not rest the tendons. Could cause more damage. |
Address the strength deficit. Heavy load 2-3 times per week. Compare with normative values not the contralateral limb. |
Tendons respond to heavy load, 70% 1RM. For approx. 5 mins then again in 6 hours. |
Type of muscle contraction does not affect collagen synthesis, other evidence points to eccentrics |
Allow enough time following high load for tissue recovery (every 2nd day) |
Adjuncts to exercise
Corticosteroid injection |
Shockwave therapy |
Platelet rich plasma |
Surgical management |
