tendon pathology

A number of processes can cause tendon pathology and there is a discrepancy in terminology reflecting the unclear pathophysiology.

Terminology

  • tendinopathy: general umbrella term for pain and swelling of a tendon
  • tendinitis
  • tendinosis
    • chronic tendon injury with cellular-level damage
    • some authors specifically define it as tendinopathy of the mid-tendon
  • tenosynovitis: pain and swelling affecting a fully-developed tendon sheath +/- tendinosis
  • paratenonitis/peritendinitis/paratendinopathy: inflammation of the paratenon +/- tendinosis
  • tendon entrapment
  • tendon rupture
  • tendon instability (subluxation and dislocation)

Pathology

Tendon pathology can be:

  • degenerative
  • traumatic, e.g. acute ruptures, lacerations
