Achilles Tendinitis
Overview
Achilles tendonitis (tendinitis), is a painful and often debilitating inflammation of the Achilles tendon than can progress into degeneration which we call Achilles Tendinosis. The Achilles tendon is the largest and strongest tendon in the body. It is located in the back of the lower leg, attaches to the heel bone (calcaneus), and connects the calf muscles to the heel bone. In most cases, Achilles tendonopathy's are overuse injuries are more common among athletes and people who train heavily, however it can also occur in people who are less active. Achilles Tendonitis can vary in severity from a mild pain in the tendon during a particular activity to more severe cases when any form of activity that puts strain on this ligament, even standing or walking, can cause pain.
Causes
The cause of paratenonitis is not well understood although there is a correlation with a recent increase in the intensity of running or jumping workouts. It can be associated with repetitive activities which overload the tendon structure, postural problems such as flatfoot or high-arched foot, or footwear and training issues such as running on uneven or excessively hard ground or running on slanted surfaces. Tendinosis is also associated with the aging process.
Symptoms
Most cases of Achilles tendonitis start out slowly, with very little pain, and then grow worse over time. Some of the more common symptoms include mild pain or an ache above the heel and in the lower leg, especially after running or doing other physical activities, pain that gets worse when walking uphill, climbing stairs, or taking part in intense or prolonged exercise, stiffness and tenderness in the heel, especially in the morning, that gradually goes away, swelling or hard knots of tissue in the Achilles tendon, a creaking or crackling sound when moving the ankle or pressing on the Achilles tendon, weakness in the affected leg.
Diagnosis
A podiatrist can usually make the diagnosis by clinical history and physical examination alone. Pain with touching or stretching the tendon is typical. There may also be a visible swelling to the tendon. The patient frequently has difficulty plantarflexing (pushing down the ball of the foot and toes, like one would press on a gas pedal), particularly against resistance. In most cases X-rays don't show much, as they tend to show bone more than soft tissues. But X-rays may show associated degeneration of the heel bone that is common with Achilles Tendon problems. For example, heel spurs, calcification within the tendon, avulsion fractures, periostitis (a bruising of the outer covering of the bone) may all be seen on X-ray. In cases where we are uncertain as to the extent of the damage to the tendon, though, an MRI scan may be necessary, which images the soft tissues better than X-rays. When the tendon is simply inflamed and not severely damaged, the problem may or may not be visible on MRI. It depends upon the severity of the condition.
Nonsurgical Treatment
The best treatment for Achilles tendonitis is preventative, stretching and warming up properly before starting an activity. Proper rest, accompanied by stretching and icing to reduce swelling, can help to heal an overworked Achilles tendon. Placing an adequate heel lift in both shoes will allow the heel to have contact with the ground without placing stress on the Achilles tendon. Wear a tie shoe that is stiff soled and has a wide base, then add an over-the-counter or custom foot orthosis inside the shoe to prevent the twisting motion of the Achilles tendon due to over pronation. In the event that the tendon is unable to heal due to your life style or activity, you may have to be put in a walking cast for a short period to give it a chance to heal. You need to have the doctor, physical therapist, or come in to our facility to check for a leg length difference due to the walking cast being higher. This is to prevent any discomfort to the hips. After the tendon has healed and before the foot is taken out of the walking cast, range of motion at the ankle must be tested and if the foot is not allowed to properly bend upwards 15 degrees then the tightness in the calf will cause the foot to over pronate and reinjure. A stretching program will be needed to loosen up the calf muscle before much weight bearing is done without the cast. The stretching program can be found at the menu for feet hurt. If necessary a heel lift can be put in both shoes to help take the stress off the tendon. Should the tightness of the calves be the primary cause for the Achilles tendon damage and stretching has not loosen the Achilles tendon sufficiently, then discussion with your doctor for a calf release may have to be considered.
Surgical Treatment
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.
Prevention
Suggestions to reduce your risk of Achilles tendonitis include, incorporate stretching into your warm-up and cool-down routines, maintain an adequate level of fitness for your sport, avoid dramatic increases in sports training, if you experience pain in your Achilles tendon, rest the area. Trying to ?work through? the pain will only make your injury worse, wear good quality supportive shoes appropriate to your sport. If there is foot deformity or flattening, obtain orthoses, avoid wearing high heels on a regular basis. Maintaining your foot in a ?tiptoe? position shortens your calf muscles and reduces the flexibility of your Achilles tendon. An inflexible Achilles tendon is more susceptible to injury, maintain a normal healthy weight.
