A total of 56 patients completed a previous study regarding non-operative treatment for acute achilles tendon rupture. This study consists of an additional follow up after 4-5 years depending on original date of injury.
30 patients suffering from acute Achilles tendon rupture was originally randomized to each arm, and followed up after 6 and 12 months. Of these a total of 56 patients was included in the final analysis, and invited to participate in this additional follow-up, 4-5 years after their original injury. Originally patients was monitored using: ATRS questionnaires, ATRA: Achilles Tendon Resting Angle, Heel Raise Work: number of lifts, lift height and total work, and tests of strength and stiffness in the ankle using a kinetic dynamometer.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Early Weight Bearing | 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. |

| Control | 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. 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. |

| Early weight bearing | Behavioral | The intervention implies that the selected patients, will be allowed to bear weight on the injured leg form day 1 while wearing the orthosis, in contrast to the control group, who must wait 6 weaks. |
| Measure | Description | Time Frame |
|---|---|---|
| ATRS: Achilles Tendon Rupture Score | From initial test 6 and 12 months after injury, and now 4-5 years after. | approximate 5 years |
| Measure | Description | Time Frame |
|---|---|---|
| Heel Raise Work | The total work (joules), max height of lift (mm) and number of lifts is recorded. THe patient is placed standing on one leg on a platform tilted 10 degrees (heel below toes), and is asked to lift the heel (and thereby bodyweight) as high as possible, once every 2 seconds. When the patient can no longer maintain height or pace, the test is finished. | Test is performed once, 4-5 years after the initial injury |
