PATELLA TENDONITIS (JUMPER’S KNEE)


back

The patellar tendon / ligament join the kneecap (patella) to the shin bone (tibia). This tendon is extremely strong and allows the quadriceps muscle group to straighten the leg. The quadriceps actively straighten the knee in jumping to propel the individual off the ground as well as functioning in stabilizing their landing.

As such this tendon comes under a large amount of stress especially in individuals who actively put extra strain on the knee joint such as those who regularly perform sports that involve direction changing and jumping movements. With repeated strain, micro-tears as well as collagen degeneration may occur as a result in the tendon.

SYMPTOMS

  • Pain at the bottom and front of the kneecap especially when pressing in.
  • Aching and stiffness after exertion.
  • Pain when you contract the quadriceps muscles.
  • The affected tendon may appear larger than the unaffected side.
  • May be associated with poor vastus medialis obliquus (VMO) function
  • Calf weakness may be present

WHAT CAN THE ATHLETE DO?

  • Rest
  • Maintain fitness with other non/partial weight bearing activities such as biking, swimming, aqua jogging and elliptical training.
