Achilles-tendinitis is characterized by inflammation and pain at the Achilles tendon (back of the ankle). This tendon, sometimes called the heel cord, is the tendon attachment of the calf muscles from the leg and knee to the heel. This structure is important in standing on your toes or in the pushing-off phase of walking, running, or jumping.Achilles-tendinitis is usually a grade 1 or 2 strain of the tendon. A grade 1 strain is a mild strain. There is a slight pull of the tendon without obvious tendon tearing. (There is microscopic tendon tearing.) There is no loss of strength, and the tendon is the correct length. A grade 2 strain is a moderate strain. There is tearing of tendon fibers within the substance of the tendon or where the tendon attaches to muscle or bone. The length of the tendon or whole muscle-tendon-bone unit is increased, and there is usually decreased strength. A grade 3 strain is a complete rupture of the tendon.
Some of the causes of Achilles tendonitis include, overuse injury - this occurs when the Achilles tendon is stressed until it develops small tears. Runners seem to be the most susceptible. People who play sports that involve jumping, such as basketball, are also at increased risk. Arthritis - Achilles tendonitis can be a part of generalised inflammatory arthritis, such as ankylosing spondylitis or psoriatic arthritis. In these conditions, both tendons can be affected. Foot problems - some people with flat feet or hyperpronated feet (feet that turn inward while walking) are prone to Achilles tendonitis. The flattened arch pulls on calf muscles and keeps the Achilles tendon under tight strain. This constant mechanical stress on the heel and tendon can cause inflammation, pain and swelling of the tendon. Being overweight can make the problem worse. Footwear - wearing shoes with minimal support while walking or running can increase the risk, as can wearing high heels. Overweight and obesity - being overweight places more strain on many parts of the body, including the Achilles tendon. Quinolone antibiotics - can in some instances be associated with inflammatory tenosynovitis and, if present, will often be bilateral (both Achilles), coming on soon after exposure to the drug.
Achilles tendonitis typically starts off as a dull stiffness in the tendon, which gradually goes away as the area gets warmed up. It may get worse with faster running, uphill running, or when wearing spikes and other low-heeled running shoes. If you continue to train on it, the tendon will hurt more sharply and more often, eventually impeding your ability even to jog lightly. About two-thirds of Achilles tendonitis cases occur at the ?midpoint? of the tendon, a few inches above the heel. The rest are mostly cases of ?insertional? Achilles tendonitis, which occurs within an inch or so of the heelbone. Insertional Achilles tendonitis tends to be more difficult to get rid of, often because the bursa, a small fluid-filled sac right behind the tendon, can become irritated as well.
During an examination of the foot and ankle, you doctor will look for the following signs, Achilles tendon swelling or thickening. Bone spurs appearing at the lower part of the tendon at the back of the hell. Pain at the middle or lower area of the Achilles tendon. Limited range of motion of the foot and ankle, and a decreased ability to flex the foot. Your doctor may perform imaging tests, such as X-rays and MRI scans, to make a diagnosis of Achilles tendinitis. X-rays show images of the bones and can help the physician to determine if the Achilles tendon has become hardened, which indicated insertional Achilles tendinitis. MRI scans may not be necessary, but they are important guides if you are recommended to have surgical treatment. An MRI can show the severity of the damage and determine what kind of procedure would be best to address the condition.
There is insufficient evidence from randomised controlled trials to determine which method of treatment is the most appropriate for the treatment of acute or chronic Achilles tendonitis. The patient should abstain from aggravating activities, but with a minimum of rest in order to preserve overall fitness. Possible treatments are non-steroidal anti-inflammatory drugs (NSAIDs), ice, rest, increased warm-up/stretching exercises, physiotherapy and heel lifts (orthotic devices - used on both sides to prevent a gait imbalance). Other treatments evaluated in a Cochrane review were heparin, steroid injections, glycosaminoglycan sulfate, Actovegin?, and topical laser treatment. There was no clear evidence of benefit from these. Casting is an option for resistant Achilles tendonitis. Drugs - analgesics and NSAIDs. Surgery is sometimes used for resistant Achilles tendonitis, but usually as a last resort. Other recently reported treatments include continuing sporting activity in conjunction with rehabilitation, low-energy shock wave therapy and topical glyceryl trinitrate .
Many people don't realize that Achilles tendon surgery can be very traumatic to your body. The type of trauma you experience after surgery can be compared to what you go through when you first injured your Achilles tendon. During the first 24 to 72 hours after the surgery your ankle will be tender, swollen and very painful. Your leg will be weak and unstable making it impossible for you to put weight on your leg without some kind of help. This is why your doctor or surgeon will have you outfitted for a cast, ankle brace and/or crutches before the procedure. When you are relying on a cast/brace and crutches your Achilles tendon is less likely to be as active as it once was. This is usually why atrophy (loss) of your lower leg muscles (specifically your calf muscle) happens. In general, more than 80%* of people who undergo surgery for an injured Achilles Tendon are able to return to their active lifestyle. In order to avoid re-injury, it is important to commit to a regular conservative therapy routine.
To prevent Achilles tendonitis or tendonosis from recurring after surgical or non-surgical treatment, the foot and ankle surgeon may recommend strengthening and stretching of the calf muscles through daily exercises. Wearing proper shoes for the foot type and activity is also important in preventing recurrence of the condition.
