Achilles Tendon Rupture – Management and Rehabilitation

This leaflet will provide you with information about the nature of your injury as well as the management and rehabilitation process following your Achilles tendon rupture.

What is an Achilles Tendon Rupture?

The Achilles tendon is the largest tendon in the human body. It connects your calf muscles (gastrocnemius and soleus) to your heel (calcaneus). It is rope-like in nature, made up of many bundles of a strong material called collagen, which is the body’s main tissue building block, making it strong and flexible. When the calf muscles contract, the Achilles tendon is tightened, pulling the heel bone. The Achilles tendon is very important when walking, running and jumping and it is responsible for the movement involved in coming up onto your tiptoes. A complete tear through the tendon is called an Achilles tendon rupture.  This injury can occur unexpectedly, or more commonly during sports including running.

The diagrams above show a side view of your Achilles tendon. On the left is a healthy Achilles tendon. On the right, an Achilles tendon following a rupture is pictured.

Causes of Achilles Tendon Rupture

The Achilles tendon can rupture without warning, although it is more commonly injured during sporting activities. This injury affects about 1 in 15,000 people at any one time, increasing to 1 in 8,000 in competitive athletes.

The Achilles tendon can be torn if there is a high force or stress placed upon it. This can happen in activities which involve a forceful push off movement such as football, tennis, badminton or squash. The push off movement uses a strong contraction of the calf muscles which can cause too much stress to the Achilles tendon. The Achilles tendon can also be damaged by injuries such as falls and slips where the foot is suddenly forced into an upward position (dorsiflexion).

Another factor which makes an individual more at risk of having an Achilles tendon rupture is weakness in the tendon itself.   This weakness could be due to specific medical conditions including rheumatological conditions or medication combinations such as steroids and certain antibiotics. It can also occur when there have been long term Achilles tendon problems such as tendinopathies. This is where the tendon becomes swollen and painful and leads to small tears within the tendon. These tears cause the tendon to become increasingly weak and therefore more susceptible to a rupture.

Symptoms of an Achilles Tendon Rupture

The main symptoms of an Achilles tendon rupture include:

  • Sudden, sharp pain in the back of your ankle where the tendon is located.
  • A snapping or popping sound alongside your pain.

This pain may settle completely or turn into a dull ache at your calf or heel. After your injury you may also find some swelling and bruising in your calf. Walking, particularly rising onto your toes, becomes more difficult. You may find that you begin to walk with a flatter foot, being unable to push your foot off the ground on the injured side.

Diagnosis

An Achilles tendon rupture is usually diagnosed through your symptoms as well as a doctor taking a history of your injury followed by an examination.

A gap may be able to be felt in the tendon, usually 4-5 cm above the heel bone, as this is the normal site of the injury. The tear can also occur higher up about 10cm above the insertion into the heel, at the site where the muscles join the tendon; this is known as a musculo-tendinous tear.

A special calf squeeze test will be performed. Normally if the Achilles tendon is intact this causes the foot to point downwards but if it is ruptured it causes no movement.

Treatment Options

Non-Surgical Management of a Ruptured Achilles Tendon

Your injury will be managed conservatively, meaning you do not require surgery.You will be treated in an Equinus cast (foot pointing down) for 2 weeks. At this time, you will prescribe a 5-week dosage of anti-coagulant medication. This is a preventative measure against developing a deep vein thrombosis (DVT) whilst your ankle is immobilised.

At approximately 2 weeks following rupture you will be fitted with a VACOped boot by a physiotherapist. You will be required to wear this boot for a minimum of 8 weeks.

Your rehabilitation and progression will be managed by a physiotherapist. Your physiotherapist will adjust the boot and progress weight bearing ability in line with trust guidelines. They will also provide you with advice as well as exercises for your ankle, lower limb and cardiovascular fitness as appropriate.

Precautions Whilst in the Boot

  • The boot must be worn full time apart from when doing the physiotherapy exercises or for hygiene purposes. When washing your foot remember to keep your foot resting/pointing down and do not stretch your ankle.
  • The boot must be worn at night.
  • When out of the boot do not stretch the Achilles tendon using your hands or any strap/band etc.
  • Without the boot on do not weight bear/ walk on your foot
  • You must follow the guidance given by your physiotherapist as to how much weight to bear through your leg and what walking aids you should use.

VACOped Boot with Fabric liner

The VACOped boot is a specialist orthotic designed specifically for this injury. It controls the range of movement at your ankle, allowing for your Achilles tendon to heal in the correct position.

The VACOped boot will be fitted by your physiotherapist. This will include the hard outer shell, an angled detachable sole, a vacuum bead lining and a fabric liner. You will also be given the following items so please ensure you keep these safe.

  • Adjustment key
  • Vacuum bead bulb pump
  • Spare removable cloth liner
  • Detachable rocker sole

Your physiotherapist will teach you how to put the boot on and take it off, as well as how to inflate the vacuum bead liner by opening the valve. They’ll also show you how to deflate it—the pump removes air, which makes the beads firm.

Looking after yourself and your boot

• Re-adjust the liner and pump out the air in your boot every morning and each time you refit it.
• Wearing a sock inside the boot is not recommended, as it may increase the risk of pressure areas and skin irritation. The liner is designed to wick away moisture on its own.
• Place the liner on your foot, secure it with the Velcro straps, and then position your foot and liner together inside the Vacoped boot for optimal fit.
• If the boot causes pressure or discomfort on your skin, you may apply a protective plaster or soft padding to the affected area. You can also remove the liner and adjust the polystyrene beads if they appear unevenly distributed.
• If you experience hip or back discomfort due to the altered walking pattern caused by the boot, consider using a shoe-height adjustment product (such as a wedge or a thick-soled shoe) on the non-affected leg. The EVENUP shoe, supplied by Oped (the manufacturer of the Vacoped boot), is one option. Although we do not supply this product, it can be purchased directly from Oped—see the FAQ for the web address.

Changing and Washing Liner

  • Two or three times a week, when removing your boot or changing the liner you need to give the inner liner a good shake to spread the beads equally all over. This is to make sure your boot works correctly and to avoid pressure areas.
  • To change the cushion liner simply unzip it, remove the inner liner, and put it in to a clean cushion liner. Make sure each section comes in to the appropriate pouch in the cushion liner and the valve comes out through the designated hole.
  • Then zip it back and put it on.
  • You can wash the cushion liner in the washing machine up to 60°C.

VACOped Boot with XELGO liner

The VACOped boot is a specialist orthotic designed specifically for this injury. It controls the range of movement at your ankle, allowing for your Achilles tendon to heal in the correct position.

The VACOped boot will be fitted by your physiotherapist. This will include the hard outer shell, an angled detachable sole, a cushioned liner, and a sock.

You will also be given the following items so please ensure you keep these safe.

  • Adjustment key
  • 1 pair of wicking socks (1 to wash and 1 to wear)
  • Detachable rocker sole

Looking after yourself and your boot

  • When refitting the boot, ensure to readjust the liner, for comfort.
  • Put the liner in the boot, ensuring the heel part is as far in as possible so the liner does not come over the end of the foot plate.
  • It is recommended to wear the sock whilst in the boot.
  • The sock and liner are designed to wick away the sweat.
  • If your boot is creating pressure or discomfort, you can place a protective plaster or soft padding on the affected area(s). Please inform your physiotherapist.
  • If you feel your hips or back are suffering because of the uneven walking pattern that wearing the boot causes, there are products on the market (such as wedges) or wearing a thick soled shoe that can help with that by providing extra height under your non-affected leg. For example, the EVENUP shoe that can be provided by Oped. We do not supply this product, but it can be purchased from Oped. Please see FAQ for web address.

Washing the Cushioned liner and sock

  • The liner and sock can be washed two or three times a week, in the washing machine up to 30°C.
  • Please DO NOT tumble dry or dry the cushioned liner on a radiator as this will affect the beads and viscous liquid inside the liner. The cushioned liner can be rung out and air dries quickly. 
  • The manufacturers have suggested a few simple steps that can help speed up the drying process. During their testing, they found that the liner was touch-dry as soon as they came out of the washing machine, and fully dry within around 30 minutes when placed outside in warm weather or near a radiator.
  • To achieve similar results, they recommend:
  • Washing the liner on its own, or with a very small load (such as a couple of pairs of socks and a T-shirt).
  •  Ensuring the washing machine’s spin cycle is activated at the end of the wash to remove as much water as possible.
  • After washing, gently rubbing and squeezing the liner with a towel to absorb any remaining moisture.

Treatment Programme and Timeframe

The above time frame is only guidance and is subject to change dependant on individual needs and progress. You will therefore be guided by your physiotherapist throughout this process.

Treatment weeks  Treatment
Week 1 – 2  Non weight bearing with  two Elbow Crutches in cast
Week 2 – 5Boot setting fixed at – 300 with wedge sole Weight bearing  with two crutches as pain allows
Week 5 – 7Boot setting range of movement change to  -150 to – 300 with wedge sole Weight bearing  with crutches
Week 7 – 9Boot setting range of movement change to 00 to – 300 with flat sole Weight bearing with crutches as tolerated
Week 9 – 10Boot setting range of movement unlocked fully (+200 to – 300) to allow full free movement with use of one or no elbow crutches as able.  
Week 10 – 12+Gradually wean out of boot into normal shoes, use of elbow crutches to normalise gait pattern during this process (You will need your other shoe when you come to physio for this change)

As you begin transitioning out of the boot at week 10, we recommend for the following six weeks you continue to use the boot in situations that may increase the risk of re-rupture. This includes instances where you may be consuming alcohol and could become unsteady, when you anticipate walking long distances, or when you will be in crowded environments such as football matches or concerts

Exercises
It is very important to keep moving ‘little and often’ whilst in your boot. This will help to limit the weakening of your muscles and reduce joint stiffness. It will also reduce your risk of developing blood clots. Below are some general exercises to keep your lower limb moving during the first few weeks in your boot.

In the first 10 weeks following injury, do not passively move the ankle greater than a right angle.
Do not force the foot up towards you.
Knee Extension
Sit comfortably in a chair. Lift your foot off the floor and straighten your knee. Hold here for 3 seconds, then slowly lower down.
Lie flat on your back. Lift your injured leg up straight about 20cm off the bed, then slowly lower down
Stand up and hold on to a surface such as kitchen work top of back of sofa. Moving from the hip and keeping your leg straight, bring your leg straight back behind you. Then move your leg out to the side and back in.
Stand up and hold on to a surface such as kitchen work top of back of sofa. Keep your knees level and lift your affected foot up towards your bottom.

For the above exercises, aim to perform each movement up to 10 times, repeating for up to 3 sets with 1 minute’s rest in between.

Active ankle ranges of movement
You can remove your boot as directed by your physiotherapist to carry out the following gentle range of movement exercises for your ankle. These exercises should be pain free. Aim to complete 10 repetitions of each exercise, three times a day.

  • Active plantar flexion (pointing your toes) (see figure A)
    Please note: when bending your ankle up and down, do not bend your ankle up past its neutral position (see figure B), we do not want to stretch your Achilles tendon at this stage. This is because the strength of the tendon is at its weakest at this time and stretching it could result in elongation (over-stretching) or re-rupture of your tendon.

Frequently Asked questions

Should my ankle swell?It is normal for the ankle to swell in the early stages of healing. The swelling should slowly dissipate during the course of your rehabilitation. Elevating your feet may help you to control the swelling.
My Calf feels tight and painfulPlease seek advice from a health care practitioner
My foot is turning Red/Purple colours at times- is this OK?It is normal to have colour changes following an injury. It tends to happen with other injuries as well.
Will my tendon look normal again?No, this is due to the tendon un-spiralling when ruptured.
Should my tendon look and feel thickened and swollen?Yes, especially in the early healing stages. In the later stages this might be a sign of overloading the tendon. If you are worried please discuss it with your physiotherapist.
What are the chances of my tendon re-rupturing?The national average is 5%. Our re-rupture rate is between 1.5 – 2%
My boot is irritating/causing pressure spots on my foot what should I do?If you are noticing irritation or pressure spots please refer to the advice in the leaflet if this does not help, please bring it to the attention of your physiotherapist
When can I drive?When you are out of the boot normally at week 10. Please discuss with your physiotherapist
How much should I walk?Slowly build from 5 minutes to 40 minutes whilst in the boot.
When can I run?Normally at 6 months post injury but your physiotherapy will start to introduce jogging at 5 months
When can I return to sport?Normally between 8 – 12 months depending on your sport.
I feel unbalanced wearing the boot and this causing my hip and back to ache is there anything I can do?This may be due to the imbalance often experienced whilst wearing the Vacoped boot. Wearing a thick soled shoe on the unaffected foot can help to level you up and ease the strain on the hip and back. There are other products on the market (such as wedges) that can help by providing extra height under your non-affected leg. Oped the company that supply the Vacoped boot offer a specially made sole called the EVENUP. We do not supply this but they can be easily purchased.
