Recent experimental and clinical evidence suggests that early loading and mobilisation for Achilles tendon ruptures may improve functional outcomes. This paper presents the results of a pilot study designed to assess the safety of immediate weight-bearing mobilisation. Twenty-eight operatively repaired patients were randomised to either immediate loading in an orthosis or traditional serial plaster casting. An independent observer, blinded to treatment, assessed the results. Improved clinical, anthropometric, and functional outcomes were noted in the immediate loading group. Ultrasound assessment confirmed no deleterious effects upon the tenodesis. There was one re-rupture of the tendon at a minimum follow-up of 1 year.
