What is patellar tendonitis?
Patellar tendonitis, also known as jumper's knee, is a condition characterized by inflammation of the patellar tendon, which connects the kneecap to shin bone (tibia). The condition may be caused by overuse of the knee joint, such as frequent jumping on hard surfaces. There may be sudden aching and pain with subsequent swelling just below the kneecap and the
knee may feel weak. Treatment includes rest, ice, and medications to relieve pain and reduce inflammation.
The most common activity causing patellar tendonitis is too much jumping. Other repeated activities such as running, walking, or bicycling may lead to patellar tendonitis. All of these activities put repeated stress on the patellar tendon, causing it to be inflamed. Patellar tendonitis can also happen to people who have problems with the way their hips, legs, knee, or feet are aligned. This alignment problem can result from having wide hips, being knock-kneed, or having feet with arches that collapse when you walk or run, a condition called over-pronation.
In addition to a complete medical history and physical examination, diagnostic procedures for jumper's knee may include a radiograph of the knee. This would involve a negative image of the knee, taken with photographic film, using exposure to x-rays or gamma rays passing through matter or tissue in the body. The best course of treatment for jumper's knee is to discontinue any activity that is causing the condition, until the injury is healed. Other treatment may include nonsteroidal anti-inflammatory medications, rest, ice pack, application (to reduce swelling), stretching and strengthening exercises.

What're the symptoms of tendinitis? - Tendinitis causes pain over the affected tendon. Tendonitis produces pain in the tissues surrounding a joint.
How is tendinitis diagnosed? - Careful pressure testing and movement of the parts is all that is necessary to identify the tendinitis. There are specific tests for specific tendons.
What is the treatment for tendinitis? - The goal of treatment for tendinitis is to relieve pain and reduce inflammation. Rest or immobilization of the affected tendons is helpful for recovery.
What is achilles tendinitis? - Achilles tendinitis is inflammation, irritation, and swelling of the Achilles tendon (the tendon that connects the muscles of the calf to the heel).
