Types

  • Tendinitis — acute inflammation, usually from overuse
  • Tendinosis — chronic degeneration without active inflammation
  • Partial tear — some fibers torn, function partially preserved
  • Complete tear — full rupture, often needs surgery

Symptoms

  • Pain at the tendon, often worse with activity
  • Stiffness, especially in the morning
  • Tenderness
  • Swelling
  • Weakness or loss of function (more with tears)
  • Snap or pop with rupture

Treatment

Conservative

  • Rest, ice, compression, elevation
  • NSAIDs for acute tendinitis
  • Physical therapy and eccentric exercises (especially for tendinosis)
  • Bracing or activity modification

Procedures and surgery

  • Corticosteroid injections (use with caution near load-bearing tendons)
  • Platelet-rich plasma injections
  • Shockwave therapy
  • Surgical repair for complete tears or refractory cases
