There is a large tendon that attaches your knee cap to your shin bone; it allows you to be able to extend your leg. If this tendon becomes inflamed or irritated, you may be diagnosed with patellar tendinitis. You are at a higher risk of developing this injury if you participate in sports that involve a lot of jumping. Repetitive movement may cause the tendon to become overworked. If you notice the signs or symptoms of this condition, take steps to treat it right away so your injury does not become worse.
Knee Pain
The Mayo Clinic states that knee pain is usually the first symptom of patellar tendinitis. The pain may be sharp and become worse when you run, jump or increase the intensity of your workout. The sharp pain may get better when you stop your activity, but your knee may continue to be achy, even when resting. If your condition goes untreated, the pain may eventually become constant and interfere with daily activities and sleep.
Other Symptoms
If you have patellar tendinitis, your knee may begin to feel tight and be hard to bend or straighten. Going up and down the stairs may become difficult and painful. You may develop swelling in and around the kneecap and you may feel your tendon popping as you move. The area around your kneecap may also become tender to the touch.
Muscle Weakness
Having patellar tendinitis may cause you to favor your knee. Over time, this can lead to weakness in the muscles of your thigh and calf. In addition, the tendon can tear, leading to chronic pain. In severe cases, the tendon can rupture. If this occurs, you will have terrible pain and you will not be able to straighten your knee at all.
