Objective:

The purpose of this study is to assess the clinical and functional results of patients with acute middle third of Achilles tendon rupture treated conservatively by orthopedic boot and early weight-bearing.

Material and methods:

This is a prospective observational study with 19 patients with acute Achilles tendon rupture treated by conservative treatment. Demographic variables, ATRS score, function using heel-rise test, calf circumference and Achilles tendon resting angle were analyzed. The clinical and functional registration was performed at six weeks, three, six and 12 months of injury. A statistical analysis was performed.

Results:

At one year follow-up, the 94% of patients were capable of standing single heel rise, the mean of twin atrophy was 1.03 cm ± 0.51 compared to uninjured side and the difference of Achilles tendon resting angle was 5.63 degrees ± 4.17 compared to contralateral limb. The 83.24% of patients returned to play and the mean of ATRS score was 87.41 points ± 17.78. Two partial re-rupture (11%) were occurred at three months of follow-up, which continued with orthopedic treatment.

Conclusions:

Based on the results, functional orthopedic treatment using orthopedic boot and early weight-bearing presents good clinical and functional outcomes, considering it a valid treatment for acute Achilles tendon ruptures.
