Achilles tendinitis occurs when the band of tissue that connects the calf muscles at the back of the lower leg to the heel bone, the Achilles tendon, becomes inflamed. This condition is a result of overuse from intense exercise, jumping, running, and other activities that strain the tendon and calf muscles.
Tendinitis most often occurs when a tendon is over used. As the foot extends the Achilles tendon engages the calf muscles. The calf muscle generates force, which is transferred to the foot via this tendon. As this action repeats the tendon will endure large amounts of stress. An under-trained or inexperienced athlete is most likely to be affected by tendinitis since their body is not accustomed to the stress involved with athletics. Improper foot mechanics is another common cause of Achilles tendinitis. A properly functioning foot will distribute weight evenly across the foot. On the contrary, if the foot is experiencing improper mechanics, the weight of the body will not be evenly distributed. This can result in tendinitis, plantar fasciitis, calluses, bunions, neuromas and much more.
Patients with this condition typically experience pain in the region of the heel and back of the ankle. In less severe cases, patients may only experience an ache or stiffness in the Achilles region that increases with rest (typically at night or first thing in the morning) following activities which place stress on the Achilles tendon. These activities typically include walking or running excessively (especially uphill or on uneven surfaces), jumping, hopping, performing heel raises or performing calf stretches. The pain associated with this condition may also warm up with activity in the initial stages of injury. As the condition progresses, patients may experience symptoms that increase during sport or activity, affecting performance. Pain may also increase when performing a calf stretch or heel raise (i.e. rising up onto tip toes). In severe cases, patients may walk with a limp or be unable to weight bear on the affected leg. Patients with Achilles tendonitis may also experience swelling, tenderness on firmly touching the Achilles tendon, weakness and sometimes palpable thickening of the affected Achilles tendon when compared with the unaffected side.
Examination of the achilles tendon is inspection for muscle atrophy, swelling, asymmetry, joint effusions and erythema. Atrophy is an important clue to the duration of the tendinopathy and it is often present with chronic conditions. Swelling, asymmetry and erythema in pathologic tendons are often observed in the examination. Joint effusions are uncommon with tendinopathy and suggest the possibility of intra-articular pathology. Range of motion testing, strength and flexibility are often limited on the side of the tendinopathy. Palpation tends to elicit well-localized tenderness that is similar in quality and location to the pain experienced during activity. Physical examinations of the Achilles tendon often reveals palpable nodules and thickening. Anatomic deformities, such as forefoot and heel varus and excessive pes planus or foot pronation, should receive special attention. These anatomic deformities are often associated with this problem. In case extra research is wanted, an echography is the first choice of examination when there is a suspicion of tendinosis. Imaging studies are not necessary to diagnose achilles tendonitis, but may be useful with differential diagnosis. Ultrasound is the imaging modality of first choice as it provides a clear indication of tendon width, changes of water content within the tendon and collagen integrity, as well as bursal swelling. MRI may be indicated if diagnosis is unclear or symptoms are atypical. MRI may show increased signal within the Achilles.
The aim, when treating Achilles tendinitis, is to relieve pain and reduce swelling. The kind of treatment used can vary, based on the severity of the condition and whether or not the patient is a professional athlete. After diagnosis, the doctor will decide which method of treatment is required for the patient to undergo, it is likely that they will suggest a combination. Stretching achilles tendon, a doctor might show the patient some stretching exercises that help the Achilles tendon heal, as well as preventing future injury. Methods used to treat Achilles tendinitis include, ice packs – applying these to the tendon, when in pain or after exercising, can alleviate the pain and inflammation. Resting, this gives the tissue time to heal. The type of rest needed depends on the severity of the symptoms. In mild cases of Achilles tendinitis, it may mean just reducing the intensity of a workout, in severe cases it might mean complete rest for days or weeks. Elevating the foot, swelling can be reduced if the foot is kept raised above the level of the heart. Exercise and stretching, a doctor might show the patient some stretching exercises that help the Achilles tendon heal, as well as preventing future injury. They may, instead, refer the patient to a physiotherapist or another specialist. The exercises learned will improve the flexibility of the area and likely increase calf strength. Pain relievers – non-steroidal anti-inflammatory drugs (NSAIDS), such as ibuprofen can reduce pain and swelling. If you suffer from asthma, kidney disease or liver disease do not take NSAIDs without first checking with your doctor. Steroid injections, these can reduce tendon swelling, but should be performed with caution, as this process has been associated with a greater risk of tendon rupture. A doctor would likely perform the injection while scanning the area with ultrasound to reduce this risk. Compression bandages and orthotic devices, such as ankle supports and shoe inserts can aid recovery as they take the stress off the Achilles tendon.
Histological and biological studies on tendon healing have made it possible to envisage surgical repair using a percutaneous approach, with the following objectives, a minimal, and not very aggressive, operation, which is quick and easy and within the capabilities of all surgeons, the shortest hospitalisation period possible, above all, early and effective re-education, providing a satisfactory result both in terms of solidity and the comfort of the patient. The percutaneous tenosynthesis TENOLIG combines stability, reliability, patient comfort and lower overall social and professional costs for this type of lesion.
There are several things you can do to reduce the risk of Achilles tendinitis, warm up every time before you exercise or play a sport. Switch up your exercises. Slowly increase the length and intensity of your workouts. Keep your muscles active and stay in shape all year-round. When you see symptoms of Achilles tendinitis, stop whatever activity you are doing and rest.
