The Achilles' tendon is located in the leg just behind and above the heel. As the connection between the heel and calf muscle, its function is to allow the bending of the foot downwards. Generally if there is a tear to the Achilles' tendon it will be known as a rupture. This can be a partial tear or a complete tear, although partial tears are much rarer.
Your Achilles tendon helps you point your foot downward, rise on your toes and push off your foot as you walk. You rely on it virtually every time you move your foot. Rupture usually occurs in the section of the tendon located within 2.5 inches (6 centimeters) of the point where it attaches to the heel bone. This section may be predisposed to rupture because it gets less blood flow, which may impair its ability to heal. Ruptures often are caused by a sudden increase in the amount of stress on your Achilles tendon. Common examples include increasing the intensity of sports participation, falling from a height, stepping into a hole.
Typically patients present with sudden onset of pain and swelling in the achilles region, often accompanied by a audible snap during forceful dorsiflexion of the foot. A classic example is that of an unfit 'weekend warrior' playing squash. If complete a defect may be felt and the patient will have only minimal plantar flexion against resistance.
Your doctor will ask you about your symptoms and examine you. He or she may also ask you about your medical history. Your doctor may ask you to do a series of movements or exercises to see how well you can move your lower leg. He or she may also examine your leg, heel and ankle and may squeeze your calf muscle to check the movement of your foot. You may need to have further tests to confirm if your tendon is torn, which may include the following. An ultrasound scan. This uses sound waves to produce an image of the inside of your leg. An MRI scan. This uses magnets and radio waves to produce images of the inside of your leg.
Non Surgical Treatment
The other option is to allow your tendon to heal without surgery. In this case, you also need to wear a cast, splint, walking boot, or brace for 6-8 weeks. You also may have different exercises to do. If you are less active or have a chronic illness that prevents surgery, this option may be better for you.
Some surgeons feel an early surgical repair of the tendon is beneficial. The surgical option was long thought to offer a significantly smaller risk of re-rupture compared to traditional non-operative management (5% vs 15%). Of course, surgery imposes higher relative risks of perioperative mortality and morbidity e.g. infection including MRSA, bleeding, deep vein thrombosis, lingering anesthesia effects, etc.
