Achilles Tendon Rupture

Achilles Tendon Surgery
Brief summary
The purpose of the study is to investigate if delayed loading following surgical treated Achilles tendon rupture influence the clinical outcome and muscle and tendon structure after one year. The investigators hypothesize that delaying the gradual introduction of loading in the initial 26 weeks may reduce the heel-rise deficit (primary outcome) and thus improve the clinical outcome one year after surgery (primary endpoint).

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Heel-rise test | One-year follow-up | Heel-rise height deficit on the injured side relative to the uninjured side |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| The Achilles tendon rupture score (ATRS) | Recall before injury and 1 year | The Achilles tendon rupture score questionnaire is a patient-reported outcome with a possible score from 1-100, where higher scores mean a better outcome. |
| Muscle fascicle length and doppler activity in the tendon | 2 weeks, 3 months, 6 months and 1 year | Muscle fascicle length and doppler activity in the tendon will be measured with ultrasonography |
| Isokinetic plantar flexion muscle strength | 1 year | The Biodex is used to obtain isokinetic plantar flexion muscle strength during maximal contractions. |
| Tendon length and cross-sectional area | 1 week, 3 months, 6 months and 1 year | MRI will be used to measure free tendon length, tendon cross-sectional area and tendon length up to the gastrocnemius insertion. |
| Heel-rise work | 6 months and 1 year | An instrumented heel-rise test will be conducted to measure work capacity |
| The Achilles tendon resting angle (ATRA) | 2 weeks, 3 months, 6 months and 1 year | Achilles tendon resting angle will be measured using a standard goniometer. Measurements will be obtained with the knee flexed and extended. |
| Physical activity level | Recall before injury and 1 year | A questionnaire is used to measure the physical activity level (including type of activity) of the participants. |
