Jumpers knee

Patellar Tendonitis known as Jumpers knee gradually develops as the tendons in the knee gradually weakens due to microscopic damage to the Patella tendon found in the knee which gets worse and worse over time. The patella tendon is a very important tendon in your knee it is what connects your shin bone (tibia bone) to your knee cap (patella bone). The patella tendon helps you to straighten your knee properly. It is very common to see jumpers develop this condition because of the excessive jumping and landing that puts stress on the knees and over time causes the damage to the tendon to develop.


Inflammation and pain are the usual symptoms of jumpers knee.

  • Pain below the knee cap
  • The pain gets worse as you use move the knee.
  • The knee is painful to touch
  • Pain will be worst when you first wake up in the morning and the Patella Tendon will feel quite stiff and tight as well.
  • You may notice that the pain gradually gets worse and worse as the tendon becomes more damaged.

Patella Tendonitis shouldn’t be confused with Patella Tenodopathy. Patella Tendinitis is usually caused by stress and inflammation damaging this tendon tissue whilst Patella Tenodopathy is degeneration of the tendon usually caused by weakening of the tendon through old age.

What you can do!

Knee supports (which we sell here) are often a good way to protect the knee from the stresses and strains that are often the cause of the Tendinitis. Shock which can cause damage to your knees can as you run or land when jumping up through your feet to your knees so it is a good idea to wear wear shock absorbing insoles to deplete these shocks.

If you have over strained your knee and it has became inflamed putting a ice pack on the affected knee can reduce swelling and inflammation and help minimize damage to the knee.

Stretching before sport or activities where you stretch and use your knee can help improve flexibility and remove tightness from the patella tendon helping reduce the risk of damaging and pulling the tendon.
