Tendons are the tough fibres that connect muscle to bone. Most tendon injuries occur near joints, such as the shoulder, elbow, knee, and ankle. A tendon injury may seem to happen suddenly, but usually it is the result of repetitive tendon overloading. Health professionals may use different terms to describe a tendon injury.
You may hear:
Tendinitis (or Tendonitis): This actually means “inflammation of the tendon,” but inflammation is actually only a very rare cause of tendon pain. But many doctors may still use the term tendinitis out of habit.
The most common form of tendinopathy is tendinosis. Tendinosis is a noninflammatory degenerative condition that is characterised by collagen degeneration in the tendon due to repetitive overloading. These tendinopathies therefore do not respond well to anti-inflammatory treatments and are best treated with functional rehabilitation. The best results occur with early diagnosis and intervention.
What Causes a Tendon Injury?
Most tendon injuries are the result of gradual wear and tear to the tendon from overuse or ageing. Anyone can have a tendon injury, but people who make the same motions over and over in their jobs, sports, or daily activities are more likely to damage a tendon.
Your tendons are designed to withstand high, repetitive loading, however, on occasions, when the load being applied to the tendon is too great for the tendon to withstand, the tendon begins to become stressed.
When tendons become stressed, they sustain small micro tears, which encourage inflammatory chemicals and swelling, which can quickly heal if managed appropriately.
However, if the load is continually applied to the tendon, these lesions occurring in the tendon can exceed the rate of repair. The damage will progressively become worse, causing pain and dysfunction. The result is a tendinopathy or tendinosis.
