CHRONIC ACHILLES TENDON RECONSTRUCTION

Chronic Rupture of the Achilles Tendon

What is it?

When the Achilles tendon rupture is not diagnosed early on, the ends of the tendon begin to separate (retract). Walking and pushing off with the foot become increasingly difficult.

There are however other muscles in the leg which try to compensate for the loss of the Achilles and the leg muscle (the gastrocnemius muscle), but these are never sufficient to maintain the power and strength of the leg.

Due to the extra workload on the other muscles of the leg which try to compensate for the weakness, the toes begin to curl and may become permanently deformed.

Treatment of a chronic rupture of the Achilles tendon can be initiated with the use of a brace, but ultimately, surgery should be performed and is highly recommended for younger active individuals.

While a brace never restores a full function of the leg and there is always weakness, it does permit some increased strength in push off since a spring is attached to the brace which fits inside the shoe.

Surgical treatment is however ideal and should be performed as soon as possible after the diagnosis is made to maximize the return of strength before the tendon retracts too far.

The type of surgery performed depends on the size of the gap between the tendon ends and the extent of the separation that is present.

  • If the separation is minimal, then the tendon ends can be stitched together as we do for an acute rupture of the Achilles tendon.
  • If the separation is more significant, then other procedures need to be performed including the use of a special Achilles tendon graft (an allograft tendon, obtained from the tissue bank), a tendon transfer using one of your own tendons, or advancing a strip tendon from the gastrocnemius muscle to replace the gap in the Achilles tendon.

The tendon transfer uses the second strongest muscle in the leg after the gastrocnemius, which is the muscle to the big toe (the flexor hallucis longus).

General Recovery Facts

The goal of surgery is to return you to full healing and strength of the tendon in as short a time as possible. You will need to use crutches for 10 days after surgery, and then as soon as the swelling has subsided, you will begin walking on the cast.

When converted to the range of motion Moon boot there is hinge on the boot which will allow the foot to go downwards (plantarflexion) but will limit the ability of the foot to go in an upward direction (dorsiflexion).

Walking and exercise are very important after the surgery and a careful physical therapy program which I have developed in conjunction with physiotherapist and Biokineticist’s will be necessary.

You may experience a variety of sensations whilst in the cast consisting of sharp shooting, dull aches, electric shocks, throbbing, sensation of itching and these are all normal and you should not panic.

You will also be placed on DVT prophylaxis as there is a risk of blood clots shooting to the lungs with this procedure for a period of 6 weeks.

Strength of the leg after the reconstruction is good, but unfortunately, never normal after a chronic rupture reconstruction.

You will be able to push off with one leg, play tennis and exercise, but it may be difficult to run. You will need to work hard in physical therapy to regain strength in the leg.

Given the extensive nature of this type of surgery and the location of the incision, wound complications do occur and these are usually treated with alternative dressings and sometimes a low pressure vacuum dressing with the aid of a dressing Sister and may alter the specific post-operative recovery schedule discussed below.

Before & After Pics

3 months post op

Specific post-operative recovery

  • Foot is wrapped in a below half cast.
  • Elevate the leg on some pillows when awake however when sleeping elevate the base of the bed with 2 bricks or thick books so that the limb does not fall of the pillow at night and you wake up swollen.
  • Take pain and DVT prophylaxis medication as prescribed.
  • Expect numbness in foot 4-12 hours, followed by pain for usually one more day.
  • Do not allow foot to hang down.
  • If you are travelling, move the toes as much as possible to stimulate the calf muscle however travel during this time is not advisable.
  • First follow-up in the office.
  • Wound inspection for any possible complications or irritable areas with application of below-knee cast.
  • Start partial weight-bearing in cast with post-operative shoe and crutches when cast feels loose and swelling does not occur.
  • Can allow foot to hang down at 3 weeks provided no pain and swelling occurs.

CAST REMOVED

  • Cast is removed by my dressing Sister and wound inspected.
  • If incision is dry and completely healed, swimming is permitted for rehabilitation purposes taking care to not jump in the pool or apply any unnecessary force.
  • Gentle exercise on bicycle permitted preferably guided by physiotherapist.
  • At this stage planter flexion is unlocked on the range of motion boot and foot is prevented from passing neutral position and must be used for 6 weeks for any form of walking however patient does not need to sleep with this boot.
  • Sometimes a heel wedge may be necessary in the beginning and this will be removed on an individual basis.
  • If swelling is problematic you may require the use of a compression sock.
  • Start physical therapy under supervision with my protocols and this will focus on scar desensitisation and tendon glide mostly.
  • More vigorous exercise with Biokineticist for the next 8-12 weeks in order to achieve strength within 10% of the unaffected side hence clearing you for return to sport.
  • Can discontinue boot at this stage and use a shoe with a supportive sole and a slight heel lift (heel cup) inside the sole of the shoe.
  • Flat running on treadmill by 5-6 months.
  • Cutting sports by 7-9 months to a year.
  • Followup in my consultation rooms.
  • Photographs and video taken of range of motion and strength.
  • Final followup in my consultation rooms.
  • Photographs of taken a range of motion and strength.
  • Patient outcome score taken.
  • Swelling and residual weakness can often be expected up until this point.
  • Patient is usually discharged at this stage.
