The Achilles tendon is the strong fibrous band that attaches the calf muscles to the Calcaneus bone. A rupture of the Achilles tendon is a common pathology and it is the most commonly ruptured tendon in the human body. The main causes of a rupture can be overstretching of the heel during recreational sports, a forceful plantar flexion of the heel or a fall from an important height. The patient will frequently present with complaints of a sudden snap in the lower calf muscles associated with acute, severe pain. We distinguish ATR’s following the way they are generated ; acute or chronic.
Relevant Anatomical Structures
The Achilles tendon is the longest and strongest tendon in the whole human body and consists of strong, inelastic fibrous connective tissue. It is the insertion of the calf muscles ; the M. Soleus and the M. Gastrocnemius and connects these muscles to the calcaneal tuberosity. These lower leg muscles are the main plantar flexors of the ankle. When the calf muscles contract, the Achilles tendon tightens and pulls the heel bone causing the foot going in plantar flexion .
Epidemiology /EtiologyThe incidence is 7 per 100 000 per year but goes up to 15 to 25 per 100 000 per year for (recreational) athletes, with a peak incidence at the age of 30 to 50 years. ‘The literature frequently describes rupture of the Achilles tendon as a 'typical sports-related’ pathology, such as stop-and-go sports: badminton, soccer, volleyball, basketball, tennis, raquetball, squash. Eccentric movement puts an enormous amount of stress on the tendon. It affects mostely 'middle-aged weekend warriors' but this etiology accounts for only about 70% of such injuries.
Also factors such as:
● the natural ageing process
● obesity 
● use of some commonly prescribed medications 
● poor running mechanics
● over- or underpronation
● flat foot (pes planus)
● high foot arch (pes cavus)
● leg length discrepancy
● foot malalignment
● Steroid use
Those factors can increase the risk of developing a tendinopathy and subsequent rupture, often from a seemingly insignificant incident.
However, research suggests that injuries in this patient population are more likely to be missed on first examination.’An Achilles tendon rupture occurs more frequently among men than women. The male-to-female ratio is about 5:1, and more than 80% of ruptures occur during sports activities.
A complete rupture of the Achilles tendon will show the following characteristics:
● At the moment of rupture a sharp pain will be felt, as if the patient was stabbed in the heel with a dagger.
● Often the rupture will coincide with a loud crack or pop sound.
● When palpating the tendon, a gap may be felt.
● The back of the heel will be swollen.
● Decreased plantar flexion of the ankle.
● Restricted walking ability.
● A positive outcome of the calf muscle squeeze test or Thompson Test.
● Some patients will have a history of chronic tendonitis in the heel or a prior cortisone injection.
Three categories of indirect injury that may result in rupture are: (1) pushing off with a weight bearing forefoot while also extending the knee, as occurs at the beginning of a sprint, running, and some forms of jumping; (2) sudden and unexpected dorsiflexion of the ankle, which may occur when a person slips off a chair or a ladder, when stumbling into a hole, or suddenly falling forward; and (3) violent dorsiflexion of a plantar-flexed foot when one falls from a height.
In most of the available literature, an Achilles tendon rupture is described as chronic if it occurs at least 4 to 6 weeks after injury. The symptoms of chronic Achilles tendon rupture include pain, decreased strength, fatigue, and ankle stiffness. Acute ATR’s represent those less than 7 days from insult. A correct distinction needs to be made, because the treatments differ.
Differential diagnosis includes:
● Acute Achilles tendon peritendinitis 
● Tennis leg (medial gastrocnemius tear)
● Calf muscle strain or rupture
● Posterior tibialis stress syndrome
● Ligament injuries
● Posterior tibialis tendon injuries
● Peroneal injuries
This classification proposed by Kuwada in 1904, and at the time of writing, remains the most widely used system for describing Achilles tendon rupture.
Achilles tendon tears may be grouped into 4 types, according to severity of the tear and degree of retraction:
● type I: partial ruptures ≤50%
○ typically treated with conservative management
● type II: complete rupture with tendinous gap ≤3 cm
○ typically treated with end-end anastomosis
● type III: complete rupture with tendinous gap 3 to 6 cm
○ often requires tendon/synthetic graft
● type IV: complete rupture with defect of >6 cm (neglected ruptures)
○ often requires tendon/synthetic graft and gastrocnemius recession
The outcome measures used to evaluate functional results following an ATR can be broadly divided into two types: objective measures and patient-reported measures. The former are parameters directly registered by the physiotherapist, such as ankle range of motion (ROM) or calf muscle strength measurements. These objective data, derived from the patient’s physical examination, have traditionally formed the basis of functional assessment following an ATR. However, over the past two decades, it has become increasingly recognized that the patient’s own appraisal of outcome is of the most important when judging the results of a treatment. 
The best choice of outcome tools for reporting the results of treatment in patients with foot and ankle disorders remains uncertain and controversial. Nevertheless, on the basis of the available evidence, a patient treated for an ATR should be assessed with a disease-specific measure, such as the ATRS in combination with a generic measure, such as the SF-36 . The 36-item Short Form (SF-36) is a commonly used instrument for measuring the Health Related Quality of Life, it is a valid and reliable tool. The SF-36 has been proven useful in monitoring population health, estimating the burdens of different diseases, monitoring outcome in clinical practice, and evaluating medical treatment effects. . These patient-reported outcome scales focus on the patient’s perception of his/her health status, which has to be considered as the most important indicator of the success of a treatment. Patient-reported outcome scales should be complemented by objective indicators of function, such as muscle strength , calf muscle endurance  and return to previous activity level, in order to obtain a complete picture of the effect of the treatment. 
For the inspection of an ATR, the therapist may observe the patient in several positions:
1. Standing - to look for fallen arches (flat feet) and other postural complications.
2. Laying - usually on the front. This can be used to observe the tendon more closely for thickening, redness, swelling and nodules.
3. Walking and running - to look for overpronation.
4. Swelling: a swollen ankle can point to a rupture of the Achilles tendon.
5. On palpation: The Achilles tendon is easily palpable. When palpating along the entire length of the tendon, a gap may be present. 
B. Active Movements
In this part of the examination the therapist asks the patient to fulfil some active movements which can aid in the diagnosis of a tendon rupture.
There are several active movements:
● Observing the gait pattern can be an important indication for a possible rupture. A patient with an ATR can possibly not make a plantar flexion of his ankle. So if the plantar flexion movement in the walking phase is hindered and painful, it can be an indication of an Achilles rupture.  A patient with a Achilles rupture will show an overpronation of the injured ankle. The patient will also show a lack of push-off at the end of the stance phase as a result of the dysfunction of the Gastrocnemius and Soleus muscles.
● Instructing the patient to stand on his/her toes for making a plantar flexion. This will be impossible if the patient has an ATR. 
● Ask the patient to actively plantar flex the ankle. 
● Every active movement containing a plantar flexion of the heel will be almost, if totally not impossible. 
C. Special Test
There exist several special tests for the observation of an ATR:
2.Matles Test The patient lies in prone position and is asked to actively flex the knee through 90 degrees. The therapeut observes the feet and ankles throughout the movement. The test is negative when the foot displays slight plantar flexion; the test is positive if the foot falls into the neutral position or the movement results in dorsiflexion. Maffulli reports a sensitivity of 0.88. 
3. Achilles Tendon Total Rupture (ATR-score)
(level of evidence 1A) 
The ATR-score is an important questionnaire that
refers to the limitations/difficulties a patient with
a tendon rupture will face. 
4. Realtime Achilles Ultrasound Thompson Test
(level of evidence 2) 
This test is exactly similar to the Thompson test, but under ultrasound visualization. It can be used by surgeons with minimal training in ultrasonography. It provides improved diagnostic characteristics compared with static ultrasound. 
Medical Management (Current Best Evidence)
After medical diagnosis of an Achilles Tendon Rupture (ATR) different kinds of therapy can be offered and evaluated. These repair methods can be either by surgery or in a non-operative way where the tendon cures in a natural way with support of a brace and rest . The results of a systematic review of Wu, Yaohong, et al (level of evidence 1a) showed that when functional rehabilitation was used, the effect of non-surgical intervention was similar to surgical treatment regarding the incidence of range of motion, a future chance of rerupture, calf circumference and functional outcomes and also the incidence of other complications was reduced. Non-surgical intervention significantly increased the rerupture rate if functional rehabilitation was not considered .
The choice which one will be applied depends on personal factors such as age of the patient, desire to have a sportive life afterwards and the individual preference. Operative repair by sewing the torn ends of the injured Achilles tendon together will reduce risk of a future rerupture but wound infection can be a possible complication factor . Therefore younger persons are recommended to choose for the operative repair and elderly and less active patients will be recommended for a more conservative, natural healing process .
There is a difference between surgery for chronic and acute ATR.
By evaluating the presence or absence of Achilles tendon stumps and the gap length of the rupture, different surgical options (V-Y advancement, gastrocnemius fascial turndown flap, or flexor halluces longus tendon transfer) can be selected for tendon repair (figure: 6) Yangjing Lin et al (level of evidence 2b)) .
Due to a high complication rate after open surgical repair, including wound infection, abnormal sensation, adhesion and thrombosis new technics which require much smaller incisions have been developed and are published in specialised literature . Minimal invasive technics and percutaneous repair become more and more common because they reduce the above mentioned complications and have both a good outcome, as described in the literature of Carmont et al (level of evidence 3a) .
There is ongoing controversy about the best post-operative treatment. A few randomised controlled trials (level of evidence 1b) have been published comparing early mobilization with immobilization after surgery. Most studies have shown slightly better results with early mobilisation or no difference in outcome. Anyway most studies agree early functional treatment is recommended .
Post-operative immobilization consists of rest by wearing a protective plaster cast or brace for about 8 weeks. Partial-weight-bearing crutches can be used 6 weeks after surgery, but strenuous sports (such as running) can only be practiced 1 year postoperatively .
More recent studies however tend to an early mobilisation. The objective is to work actively on the recovery, to prevent muscle atrophy and to regain strength and movement after surgery as a tendon requires movement to heal . These exercises are performed in the first 6 to 8 weeks after surgery with a below-knee brace which allows free plantar flexion of the ankle and walking .
The systematic review of Wu Yaohong, et al (level of evidence 1a) concludes that the findings of meta-analyses regarding surgical versus non-surgical treatment for acute Achilles tendon rupture are inconsistent. The current best available evidence suggests that a functional rehabilitation is recommended after a non-surgical intervention. If functional rehabilitation can’t be provided by a rehabilitation centre, a surgical treatment may be preferred for the healing of an acute Achilles tendon rupture. 
Physical Therapy Management (current best evidence)
On day 0, in the emergency department the diagnosis is made based on the following criteria :
1) a patient’s history with a clear sense of “snap” of the Achilles tendon
2) a palpable defect, usually located 3–6 cm above the calcaneal tubercle
3) a positive calf squeeze test . A plaster of Paris is applied to the patient’s foot in a
plantigrade position of 30–45 degrees. No weight bearing is allowed.
Whether the tendon was treated surgically or non-surgically, the patient should wear a plaster cast for immobilization for at least 6 weeks on the injured ankle or a below-knee dorsal brace which allows the ankle to make a plantar flexion to start early mobilization in the first 6 weeks after injury or surgery as described in Groetelaers, René et al.(level of evidence 1b (prospective randomized trial)) . Lantto, Iikka, et al. level of evidence 1b (RCT)  .
Rehabilitation schedule and sample physiotherapy exercises 
In general physical therapy for an Achilles tendon rupture starts immediately after the cast is removed and is mainly focused on firstly improving the range of motion (ROM) of the ankle. Later the physical therapy is focussed on increasing the muscle strength and muscle coordination . A return to activities should be expected at 4-6 months of therapy. The rate of rehabilitation greatly depends on the quality of the treatment and the motivation of the patient .
Start off with gentle passive mobilization of the ankle and the subtalar joints. Later go on to active ROM exercises. After two weeks of physiotherapy, progressive resistance exercises are added. Possible exercises for the patient are :
● Active flexion/extension of the ankle
● Ankle circles (clockwise and counterclockwise)
● Hip abduction
● Straight leg raise
● Standing hamstring curl
● Cycling on a stationary bicycle
► 8-12 weeks after surgery :
Ten weeks after the injury or surgery, gait training exercises can be started, followed by activity specific movements. The patient can start with a thera-band exercise program by starting from the lowest resistance and work up from there for regaining strength. The patient should also continue with the previous exercises.
● Ankle range of motion : plantar flexion and dorsiflexion to 90° : 2 x 8 repetitions
● Ankle range of motion : inversion and eversion
● Ankle range of motion : pronation and supination : 2 x 8 repetitions
● One leg standing balance exercise : 3 × 30 seconds 
● Standing heel-rise (2 × 3 seconds tempo) : 3 × 10 repetitions
● Calf stretch
► 12-24 weeks after surgery :
The first set of exercises can now be executed with ankle weights. The following exercises can be added to the training program, but also basic exercises (described above) should still be executed :
● Toe raises
● Single leg balancing
● Walk on toes with support to start with (if needed) : 2 × 5 meters
● Standing heel-rise is performed with increased weight on injured leg :
5 × 10 repetitions
● Heel-rise in supine position with flexed legs
(with increased weight on injured leg) : 2 × 15 repetition
● Leg press with one leg at a time (10 repetitions maximum) : 2 × 10 repetitions
● Balance exercises on a trampoline : 2 × 45 seconds
● Walk/jog on a trampoline : 2 × 45 seconds
● Cross trainer : 1 min and 45 seconds
● The plank (core exercise) : 2 × 45 seconds
● Lunges (only with injured leg in front) : 2 × 10 repetitions
→ This program is performed as circle training.
► Starting from week 14 until the end of the therapy
The patient is able to run approximately 14 weeks after the injury or surgery.
● Running on even ground is allowed when the patient can perform 5 single-legged heel-rises with approximately 90% of the height of the
uninjured leg. 
● Jogging upwards on stairs is allowed if the patient can walk 5 meters on their toes without the heel falling down.
The last step after surgery is eccentric exercise. During the eccentric part (lowering the heel), the patient has full weight on the injured foot, and during the concentric part (raising on tiptoe) only the non-injured foot is used .
• Patient takes places on a step, standing with full bodyweight on the forefoot of both feet, the knees are extended. Then he is asked to go
stand on his/her toes and to raise the non-injured leg so that his/her bodyweight is on his injured leg. Now the patient slowly lowers the
heel. In this way the calf muscle eccentrically guides the motion and is eccentrically trained.
• When the patient can perform this exercise without discomfort, he/she can increase the load by adding books or other weight to a
backpack, or to perform the exercise with a flexed knee.
When treated with an eccentric training program, the patient is more likely to be able to return faster to sport. The eccentric exercises should reduce pain and tendon thickness and should improve function of the tendon (and muscles). The eccentric calf-muscle exercises, as described below, should be executed twice daily for 12 weeks. The exercise program consists of 1-3sets of 15 repetitions per exercise, according to the improvement of the patient as described in . Murali K. Sayana, Maffulli N. et al, level of evidence 2b (individual cohort study) .
But not all patients benefit equally from an eccentric exercise program. It’s also proven that these exercises are less effective in sedentary people in comparison to athletes (Roos, M.E., et al., level of evidence 1b) .
► End of the therapy :
After completing the rehabilitation program, new examination of the tendon healing and functions is required. If needed, a new referral for further physiotherapy sessions can be provided to the patient. Gradual return to sports is recommended. For example before participating to contact sports, the patient should wait at least 6–9 months after the injury.

Clinical Bottom Line
An Achilles Tendon Rupture also known as ATR is described as a typical sports-related pathology. We distinguish two sorts of ruptures: a complete rupture or a partial rupture. An ATR can be treated surgically or nonsurgically. Medical therapy consists of an operative repair by sewing the torn ends of the injured Achilles tendon together. The physical rehabilitation changes from physical non-weight bearing exercises (at the beginning of the therapy) to more weightbearing exercises at the end of the revalidation.
