Achilles Tendinitis is the inflammation of the Achilles Tendon located in the heel, and is typically caused by overuse of the affected limb. Most often, it occurs in athletes who are not training with the proper techniques and/or equipment. When the Achilles Tendon is injured, blood vessels and nerve fibers from surrounding areas migrate into the tendon, and the nerve fibers may be responsible for the discomfort. Healing is often slow in this area due to the comparably low amount of cellular activity and blood flowing through the area.
Achilles tendinitis usually results from overuse and not a specific injury or trauma. When the body is subject to repetitive stress, the Achilles tendon is more prone to become inflamed. Other factors may cause Achilles tendinitis, such as, Sudden increase in physical activity, which can be related to distance, speed or hills, without giving yourself adequate time to adjust to the heightened activity. With running up hills, the Achilles tendon has to stretch more for each stride, which creates rapid fatigue. Inadequate footwear or training surface. High heels may cause a problem, because the Achilles tendon and calf muscles are shortened. While exercising in flat, athletic shoes, the tendon is then stretched beyond its normal range, putting abnormal strain on the tendon. Tight calf muscles which gives the foot a decreased range of motion. The strained calf muscles may also put extra strain on the Achilles tendon. Bone spur where the Achilles tendon attaches to the heel bone, aggravating the tendon and causing pain.
The Achilles tendon is a strong muscle and is not usually damaged by one specific injury. Tendinitis develops from repetitive stress, sudden increase or intensity of exercise activity, tight calf muscles, or a bone spur that rubs against the tendon. Common signs and symptoms of Achilles Tendinitis include, gradual onset of pain at the back of the ankle which may develop in several days up to several months to become bothersome. Heel pain during physical activities which may diminish after warming up in early stages, or become a constant problem if the problem becomes chronic. Stiffness at the back of the ankle in the morning. During inactivity, pain eases. Swelling or thickening of the Achilles tendon. Painful sensation if the Achilles tendon is palpated. If a pop is heard suddenly, then there is an increased chance that the Achilles tendon has been torn and immediate medical attention is needed.
Your physiotherapist or sports doctor can usually confirm the diagnosis of Achilles tendonitis in the clinic. They will base their diagnosis on your history, symptom behaviour and clinical tests. Achilles tendons will often have a painful and prominent lump within the tendon. Further investigations include US scan or MRI. X-rays are of little use in the diagnosis.
The aim of the treatment is to reduce strain on the tendon and reduce inflammation. Strain may be reduced by, avoiding or severely limiting activities that may aggravate the condition, such as running, using shoe inserts (orthoses) to take pressure off the tendon as it heals. In cases of flat or hyperpronated feet, your doctor or podiatrist may recommend long-term use of orthoses. I8nflammation may be reduced by, applying icepacks for 20 minutes per hour during the acute stage, taking non-steroidal anti-inflammatory drugs, placing the foot in a cast or restrictive ankle-boot to minimise movement and give the tendon time to heal. This may be recommended in severe cases and used for about eight weeks. Occasionally depot (slowly absorbed) steroid injections may be tried, particularly for peri-tendinitis, but great care needs to be taken to avoid injecting into the tendon. This should only be done by a specialist doctor. You may also be given specific exercises to gently stretch the calf muscles once the acute stage of inflammation has settled down. Your doctor or physiotherapist will recommend these exercises when you are on the road to recovery. Recovery is often slow and will depend on the severity of the condition and how carefully you follow the treatment and care instructions you are given.
Mini-Open Achilles Tendon Repair. During a mini-open Achilles tendon repair surgery, 2 to 8 small stab incisions are made to pull the edges of the tendon tear together and suture the torn edges to repair the damage. During this procedure the surgeon will make one 3 to 4 cm long incision on the back of your ankle and 2 to 4 smaller vertical incisions around the long incision. These smaller veritical incisions are made with a pair of surgical scissors and are commonly referred to as “stab incisions”. Once the incisions are opened up, the surgeon will place precise sutures with non-absorbable stitches to strengthen the damaged Achilles tendon tissue. This suturing technique reduces the amount of scar tissue on the tendon after surgery and provides better surface healing of the skin. Unlike the traditional method of an open surgery, this procedure has less risks and complications involved. To learn about all risks you may face be sure to speak to your doctor.
Stay in good shape year-round and try to keep your muscles as strong as they can be. Strong, flexible muscles work more efficiently and put less stress on your tendon. Increase the intensity and length of your exercise sessions gradually. This is especially important if you’ve been inactive for a while or you’re new to a sport. Always warm up before you go for a run or play a sport. If your muscles are tight, your Achilles tendons have to work harder to compensate. Stretch it out. Stretch your legs, especially your calves, hamstrings, quadriceps, and thigh muscles – these muscles help stabilize your knee while running. Get shoes that fit properly and are designed for your sport. If you’re a jogger, go to a running specialty store and have a trained professional help you select shoes that match your foot type and offer plenty of support. Replace your shoes before they become worn out. Try to run on softer surfaces like grass, dirt trails, or synthetic tracks. Hard surfaces like concrete or asphalt can put extra pressure on the joints. Also avoid running up or down hills as much as possible. Vary your exercise routine. Work different muscle groups to keep yourself in good overall shape and keep individual muscles from getting overused. If you notice any symptoms of Achilles tendonitis, stop running or doing activities that put stress on your feet. Wait until all the pain is gone or you have been cleared to start participating again by a doctor.
