Achilles Tendon Rupture Risk Factors

Factors that increase the chance of an Achilles tendon rupture include age, activity level, muscle imbalances, poor flexibility, certain medications, and previous tendon injuries.

Achilles Tendon Rupture: What's happening?

An Achilles tendon rupture is a complete or partial tear of the Achilles tendon, a strong band connecting calf muscles to the heel bone. This injury results from forceful contractions or sudden dorsiflexion (pointing the toes upwards) of the ankle, especially during high-impact activities.

Achilles Tendon Rupture: Diagnosis

Diagnosing an Achilles tendon rupture typically involves a physical exam, including the Thompson test (squeezing the calf to observe foot movement) and the Matles test (assessing foot dorsiflexion with the knee bent). Imaging tests, like ultrasound or MRI, are often used to confirm the diagnosis and assess the severity of the tear.

Achilles Tendon Rupture: Treatment Options

Treating an Achilles tendon rupture can involve either conservative approaches (immobilization in a cast, no weight-bearing, followed by rehabilitation) or surgical repair (stitching the torn tendon, followed by rehabilitation). The best treatment option depends on several factors, including the severity of the injury, the patient's age, and their activity level.

Achilles Tendon Rupture: Recovery Stages

Recovering from an Achilles tendon rupture involves several stages:

  • Initial immobilization: Resting the injured tendon and preventing further damage.
  • Gradual mobilization: Slowly starting to move the ankle and foot to regain range of motion.
  • Strengthening: Building strength back in the calf muscles and surrounding muscles.
  • Proprioception: Improving balance and coordination.
  • Return to activity: Gradually increasing activity levels, aiming to eventually return to desired physical activities.

Achilles Tendon Rupture: Importance of Rehabilitation

Rehabilitation is crucial after an Achilles tendon rupture to ensure proper healing, regain full range of motion, and prevent further complications. A tailored rehabilitation program includes exercises to strengthen the calf muscles, improve flexibility, and enhance proprioception (balance and coordination). This helps promote healthy healing and prevents further injury.

Achilles Tendon Rupture: Post-Treatment Assessment

Once an Achilles tendon rupture has been treated, it's important to assess the recovery process. This involves evaluating the patient's strength, range of motion, flexibility, balance, and overall function. These assessments are crucial to track progress, identify any lingering issues, and make appropriate adjustments to the rehabilitation program.

Achilles Tendon Rupture: Complications

Potential complications after an Achilles tendon rupture include:

  • Re-rupture: The tendon can re-tear, especially during early return to activity if the tissue is not fully healed.
  • Infection: This can occur, especially after surgery.
  • Delayed healing: The tendon may take longer than expected to heal.
  • Stiffness: The ankle joint may become stiff, limiting range of motion.
  • Nerve damage: Damage to nearby nerves can occur during surgery.

Study Notes

Introduction

  • Tendon tissue has been a focus of research for the last 20 years
  • Numerous studies have investigated pathological conditions and recovery
  • Defining the physiopathology, treatment, and prognosis of tendon injuries is a challenge
  • Tendon ruptures, especially of the Achilles tendon, require surgical repair and rehabilitation
  • The goal is a pain-free tendon with normal function for daily activities and sports

Anatomy and Biomechanics

  • Ankle and foot anatomy: Includes the tibiotarsal, subtalar, and transverse tarsal joints. The talus plays a major role.
  • Three regions of the Foot: Rearfoot (talus, calcaneus, subtalar joint); Midfoot (remaining tarsal bones and transverse tarsal joints); Forefoot (metatarsals and phalanges).
  • Ankle Joint Movement: Pronation (eversion, abduction, dorsiflexion) and supination (inversion, adduction, plantar flexion) are used to describe motion
  • Tarsal joints: The motion is perpendicular to an oblique axis of rotation
  • Tibiotalar joint Biomechanics: Dorsiflexion involves the superior surface of the talus rolling forward and sliding backward. Plantar flexion has the opposite movement. This happens when the ankle is unloaded.

Tendon of Achilles and Gastrocsoleus Complex

  • Anatomy: The Achilles tendon is made from the gastrocnemius and soleus muscles.
  • Variable contributions from the gastrocnemius and soleus muscles.
  • The tendons have a fibrous structure with fibers arranged in a spiral orientation.
  • Biomechanics The gastrocnemius acts as a major plantar flexor, vital in locomotion activities. The soleus, primarily a stabilizer.
  • Tendon is highly susceptible to acute and chronic injuries due to its size and function, and is load-bearing.

Incidence, Mechanisms and Risk Factors

  • Achilles tendon ruptures have increased in recent decades
  • Usually occur in middle-aged individuals
  • Common activities include running, jumping, and sprinting.
  • Three mechanisms:
    • forceful plantar flexion while the foot is on the ground
    • sudden dorsiflexion while the foot is planted and loaded
    • forceful dorsiflexion during deceleration.

Examination and Diagnosis

  • Physical exam: Includes looking for swelling, palpation for defects, and assessing mobility.
  • Special tests: Thompson test is used to check for the presence of a rupture; Matles test evaluates ankle dorsiflexion with the knees flexed.

Complementary Studies

  • X-rays: Can show unusual bone shapes or joint alignment problems, but are not primary choice.
  • Ultrasound: Preferred initial test due to its resolution, dynamic assessment (e.g. during movements), and noninvasive nature
  • MRI: Usually used to evaluate tendon tears

Classification

  • Classification systems: Various classification systems categorize tendons based on the size of the gap or the area of damage.

Treatment

  • Surgical vs. conservative: Studies have shown comparable outcomes between surgical and conservative approaches.

Post-operative Treatment and Evaluation

  • Early mobilization: The importance of using functional bracing combined with early mobilization after surgical repair is described.
  • Mobility assessments: Evaluations like the range of motion and functional scales are used to assess mobility after treatment.
  • Force assessment: Measurements for plantar flexion strength are utilized to evaluate muscular function after treatment.
  • Dynamic postural control evaluation: The Star Excursion Balance Test is used to assess the dynamic postural control of the patient.
