Primary Outcome Measures:
  • Improvement in ROM and Biodex Isokinetic Strength Testing compared to contralateral limb [ Time Frame: 2, 3, 4.5, 6, and 12 months ] [ Designated as safety issue: No ]
  • Time to return to weight bearing [ Time Frame: 2, 3, 4.5, 6, and 12 months ] [ Designated as safety issue: No ]
  • Time to return to full activity [ Time Frame: 2, 3, 4.5, 6, and 12 months ] [ Designated as safety issue: No ]

Secondary Outcome Measures:

  Eligibility

Ages Eligible for Study:   18 Years to 70 Years
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • A transverse, full thickness, acute mid-substance Achilles tendon tear that requires surgical repair
  • Achilles tendon tear is repairable by surgery using primary means as determined by intra-operative assessment
  • Achilles tendon rupture with viable ends of the tendon that are suitable for primary repair
  • Isolated Achilles tendon rupture without poly trauma
  • Patient must be 18 to 70 years of age
  • Life expectancy greater than or equal to 12 months
  • Patient is able to provide voluntary informed consent
  • Patient is willing and able to return for all follow-up visits and study related exams
  • Patient is willing to comply with prescribed physical therapy regimen

Exclusion Criteria:

  • Emergency, poly trauma patients
  • Previous Achilles tendon surgical procedure on that tendon
  • Deficit in the contralateral extremity that prevents a comparison with the treated extremity
  • Repair requires tendon lengthening, gap filling or tendon transfer
  • BMI greater than 40
  • Peripheral arterial disease
  • Uncontrolled Diabetes Mellitis
  • Patients whose injury is known to involve litigation
  • Known allergy to equine derived product
  • Systemic collagen disease
  • Neurological disease
  • Active infection - systemic or at the intended surgical site
  • Acute use of immunosuppressive agents
  • Rupture resulting from fluoroquinolone induced tendinopathy
  • Alcohol or drug abuse
  • Participant in another investigational drug or device trial
  • Pathologic soft tissue conditions that would prevent secure surgical fixation
  • Patients who are unwilling or unable to return for follow-up visits and study related exams
  • Pregnant women
  • Cancer patients
  • Decisionally impaired patients
  • Institutionalized patients
  • Prisoners
