Knee Tenonitis SymptomsDo you suffer with knee problems but are unsure about the cause? Check out the knee tendonitis symptoms below to help identify whether or not you have this condition.

Tendons are tough, fibrous bands of tissue attaching muscles and bones in your body.  They are regularly exposed to wear and tear. Tendonitis refers to inflammation of the tendons. Patellar tendonitis (knee tendonitis) is inflammation of the patellar tendon that connects the kneecap (patella) to the shin bone (tibia). Your knee joint is under a lot of continuous pressure as it supports your body weight. It is also involved in a number of movements such as bending and extending your leg.  Knee tendonitis is the commonest type of tendonitis.


 Causes of Knee Tendonitis

  • Overuse of the knee. This condition is most common in people involved in sports such as running, jumping, rugby, football, basketball, volleyball, or rowing. It is often referred to as ‘Jumper’s Knee.’ These types of activities involve extensive use of the legs that exerts high pressure on the knees. If you engage in these sports, you put repeated stress on your patellar tendon which makes your knee joint more prone to tendonitis.
  • If you have tight thigh muscles (quadriceps) and hamstrings, it can put increased strain on your patellar tendon and result in tendonitis.
  • Knee tendonitis can also occur if you have a condition like rheumatoid arthritis, an inflammatory disease of the joints.
  • Aging affects the functioning of different parts of your body and can be a factor in the occurrence of knee tendonitis.
  • Trauma or injury to the knee. If you sustain a fall or direct blow to your knee, it can cause tendonitis.


Symptoms of Knee Tendonitis

The severity of the symptoms vary with the amount of inflammation in your tendon.


  • Pain is the most common symptom associated with knee tendonitis.
  • If the tendonitis is mild – you may notice pain after exertion such as sporting activities or following a brisk walk. If the tendonitis is moderate – you may feel pain during any activities involving the knee joint. If the tendonitis is severe – the pain may stop you moving the affected knee. The pain may be constant and disrupt your sleep.
  • In older people, pain is felt when going up and down stairs.
  • Pain is usually located directly over the patellar tendon, below the knee, between your kneecap and where the tendon attaches to your shinbone (tibia).
  • You may feel pain and tightness in your knee when you kneel. Bend, squat, or straighten your leg.
  • Sitting for long periods can make the pain worse.



Inflammation causes swelling of your affected knee joint. It may be painful to touch.


Inflammation causes the affected area to feel hot to the touch.


You may experience some stiffness in the affected knee, especially in the morning. Movement of the knee may cause a crunching sensation, and grating or crackling sounds called crepitus.


Sometimes there is weakness in the affected knee. If this happens, you should seek medical attention as it may have a serious cause.

 Call your doctor if:

  • The condition gets worse.
  • You develop a fever (over 38C or 100F).
  • You feel generally ill / have flu-like symptoms, or have multiple sites of pain.

Knee tendonitis is a common condition. Left untreated, it can become chronic. If you recognize that you have these knee tendonitis symptoms then you need to begin treating the condition before it begins to get any worse.
