Achilles tendon repair

Description[edit | edit source]

The Achilles Tendon connects the calf muscles to the calcaneus (heel bone) and is one of the important tendons in the human body. The main action of the Achilles tendon is foot plantar flexion. Common pathologies include: tendinopathy, tear or rupture. Examples of mechanisms of injury for rupture includes: falling from a height, forceful plantar flexion of the ankle (as in jumping with an extended knee), or using the foot to break a fall if you stumble[1]. Clinically they present with a palpable gap on palpation, increased passive dorsiflexion, lack of heel raise and a positive Thompson Test[1]. Achilles tendon rupture is either managed conservatively with a cast or surgically with an Achilles tendon repair.

Conservative vs Surgical Intervention[edit | edit source]

There is much debate in the literature about treatment for achilles tendon rupture with the two options comprising of a conservative or surgical approach. Many studies have shown that the re-rupture rates are higher in cases of non-operative management. More recently studies have demonstrated equivalent or improved rates of re-rupture compare with surgical intervention[3][4]. However, many people continue to be treated with surgical repair and physiotherapists will continue to see them for post-operative rehabilitation in their clinics.

Visit the achilles tendon rupture page for information on conservative management.

Pre-op[edit | edit source]

Prior to surgery general oedema reduction interventions should be utilised (Rest, Ice, Compression, Elevation). The surgery will ideally occur within one week of the rupture.

Surgery Description[edit | edit source]

Many techniques exist for this surgery, including transverse, medial and longitudinal incisions. The ankle is placed in a neutral position and the severed ends of the tendon are sutured together. The surgeon will then take the ankle through complete range of motion to look at the integrity of the repair. A cast is often applied, with the surgical technique determining how long the cast stays on[5]. Many surgeons are now focusing on early weight-bearing and passive motion to improve tendon healing. A new minimally-invasive technique involves the utilisation of the peroneus brevis via two para-midline incisions. The technique reportedly preserves skin integrity over the site most prone to breakdown in a vertical incision, open reconstruction.[6] Another study recommended percutaneous repair in the recreational athlete and in patients concerned with cosmesis, and open repair for all high-caliber athletes who cannot afford any chance of re-rupture."[7]

Post-Op[edit | edit source]

Early mobilisation following achilles tendon repair has been reported to be beneficial in terms of postoperative recovery and improved tendon vascularity. Despite the increasing support for accelerated rehabilitation regimes, there is still no consensus regarding the most preferable protocol. Protocols have been developed by Brumann et al[8] and Braunstein et al[9] 

See the following clinic protocols:


Dutton[5] describes three phases of post-surgical rehabilitation following achilles tendon repair. 

Phase I[edit | edit source]

Phase I typically lasts three weeks.

Goals of this phase are as follows:

  • Control oedema and protect the repair site
  • Minimise scar adhesion and detrimental effects of immobilisation
  • Progress to full weight bearing as tolerated/indicated
  • Pain 5/10 or less, strength 4/5 all lower extremity muscles except plantar flexors

Phase I interventions include:

  • Modalities for pain and oedema
  • Stretching of large lower extremity muscle groups, gastrocnemius/soleus added at week 3
  • AROM: plantar and dorsiflexion 3x5; 3 times daily; add inversion and eversion at week 2
  • Foot/ankle isometrics at week 2; band exercises week 3
  • Proprioceptive training for lower extremities; Gait training
  • Upper extremity cardiovascular exercise
  • Joint mobilisation and soft tissue work, as indicated

Phase II[edit | edit source]

Phase II typically lasts from post-op week 4-6.

Goals for this phase are as follows:

  • Normalized gait pattern
  • Full ankle ROM
  • 5/5 lower extremity strength
  • Return to full ADL ability
  • Pain reported to be <2/10
  • Proprioceptive reactions equal to non-surgical side

Phase II interventions include:

  • Ankle flexibility at various knee angles
  • Progressive closed kinetic chain lower extremity strengthening
  • Cardiovascular progression
  • Proprioceptive training on variety of surfaces
  • Manual resisted exercises and joint mobilization, as indicated

Phase III[edit | edit source]

Phase III typically lasts from post op week 6-15.

Goals for this phase are as follows:

  • Initiate running program
  • Improve balance and coordination
  • Increase velocity of activity
  • Return to sport

Phase III interventions include:

  • Progressive ankle and lower extremity strengthening
  • Agility exercises
  • Double heel raise/lower progressing to single leg heel raise at various speeds


A recent systematic review by Brumann and colleagues (2014)[10] identified the most up-to-date rehabilitation protocol for an achilles tendon repair. They summarised their findings with the following guidelines;

Week 0 - 2[edit | edit source]

  • Nil ankle RoM
  • Orthosis fixed at 30° of PF
  • Progress to full weight bearing (FWB)

Week 3 - 6[edit | edit source]

  • FWB
  • Active ankle RoM 0-30°
  • Orthosis limited to plantargrade (0° DF) to 30° PF

Week 7+[edit | edit source]

  • Full ROM
  • Nil orthosis
