Patella Tendinitis / Jumpers Knee

Who it Effects

  • Jumping sports
  • Throwing sports
  • Weight lifting

Mechanism of Injury

  • Repeated eccentric loading of the patella tendon
  • A blow to the tendon
  • Faulty biomechanics of the knee

Signs and Symptoms

  • Gradual onset of pain
  • Pain worsened by activity
  • Thickening of the tendon
  • Stiffness after exercise / in the morning
  • Pain when the quadriceps are contracted


  • PRICE in acute stage of grade 1-3 sprain
  • Stretch the quadriceps, hamstrings and calf
  • Strengthening the quadriceps using eccentric exercises e.g. squats, particularly Vastus Medialis
  • Deep transverse frictions
  • Ultrasound
  • NSAID’s
