About

Using a population of patients from another study, who was originally randomized to 2 different types of nonoperative treatment after an acute achilles tendon rupture, the length of the achilles tendon is examined using ultrasound, and foot pressure mapping is performed, 4-5 years after the injury.

Full description

A total of 56 patients from an earlier study (see reference) on Achilles tendon rupture using nonoperative treatment with or without early weight bearing was invited for an additional follow up, where we examine the length of the Achilles tendon using ultrasound, as well as functional influence of the injury, using foot pressure mapping (FPM) during barefoot gait. Additionally the mobility of the ankle is measured with the Achilles Tendon Resting Angle (ATRA) as well as passive plantar- and dorsiflexion. Strength is measured using Heel Raise Work (height of lift, number of lifts and the total work), and supplemented with calf circumference.

Inclusion criteria

  • Suffered acute Achilles tendon rupture from April 2011 to March 2012, and then referred to Copenhagen University Hospital Hvidovre.
  • Participated and completed the original study.
  • The patient must be able to speak and understand Danish, as well as be capable to give informed consent to participating.

Exclusion criteria

  • Terminal disease or serious illnesses with an ASA score of 3 or above.
  • Any injury significantly influencing gate and function of the lower extremities other than re-rupture of the Achilles tendon.

37 participants in 2 patient groups

Early Weight Bearing
Description:
Ankle immobilized with orthosis (DJO Nextep Contour 2 Walker) with 3 1.5 cm wedges in the heel, fixing the angle between 20-30 degrees. The orthosis was used for 8 weeks, gradually removing the wedges. Full weight bearing was allowed from day 1. The orthosis was worn 24 hours / day the first 2 weeks. From week 2 controlled motion exercises and removal of the orthosis 5 times a day.
Treatment:
Behavioral: Early weight bearing
control
Description:
Ankle immobilized with orthosis (DJO Nextep Contour 2 Walker) with 3 1.5 cm wedges in the heel, fixing the angle between 20-30 degrees. The orthosis was used for 8 weeks, gradually removing the wedges. Full weight bearing was allowed from week 6. The orthosis was worn 24 hours / day the first 2 weeks. From week 2 controlled motion exercises and removal of the orthosis 5 times a day.
