Achilles tendon ruptures may be divided into full thickness ("total") and partial thickness ruptures. Total ruptures usually occur in formerly active athletes (average age 40) who resume sport activity after having been away from it for some time. In these cases, degenerative changes have weakened the tendon so much that sudden, forceful loading of the tendon causes it to tear. To some extent, these changes in the tendon could have been prevented by regular physical activity. In most cases, the injury mechanism is a strong activation of the posterior lower leg musculature, eccentrically overloading the tendon. A typical mechanism of injury involves pushing off hard with the weight-bearing foot while the knee is extended (e.g., running uphill) or sudden, unexpected dorsal extension of the ankle with reflex contraction of the calf musculature (e.g., falling down into a hole).
Achilles tendon ruptures are most likely to occur in sports requiring sudden stretching, such as sprinting and racquet sports. Achilles tendon ruptures can happen to anyone, but are most likely to occur to middle age athletes who have not been training or who have been doing relatively little training. Common sporting activities related to Achilles tendon rupture include, badminton, tennis, squash. Less common sporting activities that can lead to Achilles tendon rupture include: TKD, soccer etc. Occasionally the sufferer may have a history of having had pain in the Achilles tendon in the past and was treated with steroid injection to around the tendon by a doctor. This can lead to weakening of the tendon predisposing it to complete rupture. Certain antibiotics taken by mouth or by intravenous route can weaken the Achilles tendon predisposing it to rupture. An example would be the quinolone group of antibiotics. An common example is Ciprofloxacin (or Ciprobay).
You may notice the symptoms come on suddenly during a sporting activity or injury. You might hear a snap or feel a sudden sharp pain when the tendon is torn. The sharp pain usually settles quickly, although there may be some aching at the back of the lower leg. After the injury, the usual symptoms are as follows. A flat-footed type of walk. You can walk and bear weight, but cannot push off the ground properly on the side where the tendon is ruptured. Inability to stand on tiptoe. If the tendon is completely torn, you may feel a gap just above the back of the heel. However, if there is bruising then the swelling may disguise the gap. If you suspect an Achilles tendon rupture, it is best to see a doctor urgently, because the tendon heals better if treated sooner rather than later.
Most Achilles tendon ruptures occur in people between 30 and 50 years old and such injuries are often sport-related. If you suspect an Achilles injury, it is best to apply ice, elevate the leg, and see a specialist. One of the first things the doctor will do is evaluate your leg and ankle for swelling and discoloration. You may feel tenderness and the doctor may detect a gap where the ends of the tendon are separated. In addition to X-rays, the calf squeeze, or Thompson test, will be performed to confirm an Achilles tendon rupture. With your knee bent, the doctor will squeeze the muscles of your calf and if your tendon is intact the foot and ankle will automatically flex downward. In the case of a ruptured Achilles there will be no movement in the foot and ankle during the test.
Non Surgical Treatment
As debilitating as they can be, the good news is that minor to moderate Achilles tendon injuries should heal on their own. You just need to give them time. To speed the healing, you can try the following. Rest your leg. Avoid putting weight on your leg as best you can. You may need crutches. Ice your leg. To reduce pain and swelling, ice your injury for 20 to 30 minutes, every three to four hours for two to three days, or until the pain is gone. Compress your leg. Use an elastic bandage around the lower leg and ankle to keep down swelling. Elevate your leg. Prop you leg up on a pillow when you're sitting or lying down. Take anti-inflammatory painkillers. Nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen (Advil, Motrin) and naproxen (Aleve) will help with pain and swelling. However, these drugs have side effects, such as an increased risk of bleeding and ulcers. They should be used only occasionally unless your health care provider says otherwise and should be taken with food. Check with your doctor before taking these if you have any allergies, medical problems or take any other medication. Use a heel lift. Your health care provider may recommend that you wear an insert in your shoe while you recover. It will help protect your Achilles tendon from further stretching. Practice stretching and strengthening exercises as recommended by your health care provider. Usually, these techniques will do the trick. But in severe cases of Achilles tendon injury, you may need a cast for six to 10 weeks or even surgery to repair the tendon or remove excess tissue.
The procedure generally involves making an incision in the back of your lower leg and stitching the torn tendon together. Depending on the condition of the torn tissue, the repair may be reinforced with other tendons. Surgical complications can include infection and nerve damage. Infection rates are reduced in surgeries that employ smaller incisions. Rehabilitation. After treatment, whether surgical or nonsurgical, you'll go through a rehabilitation program involving physical therapy exercises to strengthen your leg muscles and Achilles tendon. Most people return to their former level of activity within four to six months.
To prevent Achilles tendonitis or rupture, the following tips are recommended. Avoid activities that place an enormous stress on the heel (for example, uphill running or excessive jumping). Stop all activity if there is pain at the back of the heel. If pain resumes with one particular exercise, another exercise should be selected. Wear proper shoes. Gradually strengthen calf muscles with sit-ups if prior episodes of Achilles tendonitis have occurred. Always warm up with stretching exercises before any activity. Avoid high-impact sports if prior episodes of Achilles tendon injury.
