Achilles Tendon Tear & Repair
Introduction
The Achilles tendon is the most powerful tendon in the human body. Tendons are strong tissues that connect muscles to bone. The Achilles tendon is located in the lower back part of the leg and works with the calf muscles to provide forceful foot movements. Achilles tendon ruptures most commonly occur as a result of sports injuries from activities such as basketball, football, or tennis. They can also result from a condition called Achilles tendonitis. Individuals with Achilles tendonitis have weakened and inflamed tendons that are susceptible to injury.
Anatomy
The Achilles tendon is a large, strong fibrous cord that connects the calf muscles in the back of the leg to the back of the heel bone (calcaneus). The Achilles tendon and the calf muscles work together to allow individuals to point the foot downward and to raise the heel upward. People rely on it virtually every time they move their foot. This motion enables individuals to walk, jump, stand on their toes, and climb stairs. Individuals with Achilles tendon ruptures will most often not be able to perform such movements.
Causes
Achilles tendon ruptures most commonly occur in men between the ages of 30 and 50 years old that participate in sports. Sports such as basketball, football, and tennis require quick forward and backward leg movements, jumping, and cutting that can create an imbalance of pressure on the leg and foot. The Achilles tendon can rupture when the flexed foot sustains a sudden strong force and the calf muscles powerfully shorten. Achilles tendon rupture can also result from tendons weakened over time by Achilles tendonitis (chronic inflammation of the tendon).
Symptoms
A loud “pop” may be heard when the Achilles tendon ruptures. Most individuals feel a sudden painful “snap” in the back of the calf or lower leg followed by sharp severe pain. Swelling and skin discoloration in the back of the calf will often develop because of bleeding beneath the skin. Individuals are unable to point their feet downward or raise their heels upward making it difficult to walk, jump, stand on their toes, and climb stairs.
Diagnosis
In order to diagnose an Achilles tendon rupture, a physician will perform an examination and review the individual’s medical history. The Thompson Test is the most reliable physical examination to confirm a suspected Achilles tendon rupture. The test is simple to perform. The individual lies face down with the leg straight. The physician squeezes the calf muscles in the leg. If the foot does not point, the Achilles tendon may have ruptured. The foot will not be able to point because the tendon connecting the calf muscles at the heel is torn. Some physicians may order medical imaging tests, such as ultrasound or Magnetic Resonance Imaging (MRI), to determine the location and type of tendon tear. An ultrasound uses sound waves to create an image when a device is gently placed on the skin. An MRI provides a very detailed view of body structures. The MRI equipment focuses on the leg area while the individual remains very still. In some cases, x-rays are ordered to assess if the leg or heel bone was injured when the Achilles tendon ruptured.
Treatment
Each case of Achilles tendon rupture must be evaluated on an individual basis. It is important for the individual and physician to discuss and determine which treatment options are most appropriate:
If conservative Treatment and Physical Therapy failed:
Ultrasound Guided Platelet rich plasma injection or Stem Cells injection for regeneration is promising (not FDA approved) but supported by multiple Studies.
