Brief Summary

Rationale There is ongoing controversy over the optimal treatment and rehabilitation strategy of an acute Achilles tendon rupture (ATR). The highest general complication rate is reported in patients treated with percutaneous repair and early mobilization. Objectives The purpose of the study is to compare the results of two ways of postoperative regimen after treatment with the modified and biomechanically significantly stronger percutaneous repair under local anesthesia. Methods \& Population All the consecutive patients with an acute complete Achilles tendon rupture who will agree to take part in a study will be randomized after a modified percutaneous repair under local anesthesia into functional group (FG), using a modified brace and immobilization group (IG), wearing a rigid plaster, in both groups for the period of 6 weeks. After that they will follow the same (standardized) rehabilitation protocol. Major and minor complication rate, diameter of the healed tendon, active and passive ankle range of motion (using neutral zero method), standing heel-rise test (with 25 repetition within a minute for a grade of normal) and clinical outcome using American Foot and Ankle Society (AOFAS) hindfoot-ankle score, return to the previous activity level, presence of associated complaints and subjective assessment (scored as good, fair or poor) will be assessed. Time frame This will be a 4-year study with a 3-year follow-up. Expected outcomes: There will be no differences in demographic parameters (age, gender, side and mechanism of the injury) between groups. Patients in the FG will reach sooner final range of motion (ROM) and muscular strength without limping and will be (subjectively) more satisfied with the treatment. There will be no statistically significant differences observed between groups according to the number of complications and in the end functional results with return to pre-injury activities.

Outcome Measures

Primary Outcomes (4)

  • Change in Post-operative range of motion

    Assessment in change of dorsiflexion (maximum 0-20 degrees) and plantar flexion (maximum 0-50 degrees), measured with goniometer (Reference: Ryf C, Weyman A. The Neutral Zero Method - A Principle of Measuring Joint Function. Injury. 1995;26(Suppl 1)).

    After 2 months, 3 months, 6 months, 12 months and after 3 years post op.

  • Change in Post-operative strength

    Heel rise test (rising on toes with both legs, operated leg and non-operated leg, 25 times in 60 seconds). (Reference: Lunsford BR, Perry J. The standing heel-rise test for ankle plantar flexion: criterion for normal. Phys Ther. 1995;75:694-8).

    After 3 months, 6 months, 12 months and after 3 years post op.

  • Number of complications

    Clinical findings of occurence * Major complications (Rerupture, Second rerupture, Permanent equinus position of the foot, Extreme lengthening of the Achilles tendon, Deep infection, Chronic fistula, Necrosis of the skin, Deep vein Thrombosis, Embolism, Death) and * Minor complications (Superficial infection, Wound hematoma, Delayed wound healing, Adhesion of the scar, Disturbances of sensibility, Suture granuloma, Suture rupture)

    Final results after 3 years

  • American Foot and Ankle Society (AOFAS) hindfoot-ankle score

    Filling of AOFAS questionnaire (0 - worst outcome, 100 - best outcome) (reference: 1.Kitaoka HB, Alexander IJ, Adelaar RS, Nunley JA, Myerson MS, Sanders M. Clinical rating systems for the ankle-hindfoot, midfoot, hallux, and lesser toes. Foot Ankle Int. 1994;15:349-53.)

    Final result after 3 years

Secondary Outcomes (3)

  • Patient's subjective assessment of treatment

    Final assessment after 3 years

  • Patient's report to previous activities

    Final assessment after 3 years

  • Patient's report about return to sports activities

    Final assessment after 3 years

Eligibility Criteria

Age18 Years+
Sexall
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • patients 18 years of age or older
  • a rupture that occurred no more than 7 days before the operating procedure
  • closed, complete ATR
  • a rupture that occurred in the tendinous portion (2-8 cm proximal to the insertion)
  • informed consent

You may not qualify if:

  • no previous operative procedures or history of partial or complete rupture of the involved tendon
  • no previous local, oral or parenteral therapy that might have weakened the tendon (for instance local infiltration of anesthetics or steroids in the AT region, oral or parenteral immunosuppressive therapy in patients with transplanted organs or immune diseases etc.).
