Traditionally, the ruptured tendon is held still in a plaster cast for \u2265\u20098 weeks.

Over 93% of participants completed follow-up. There was no statistically significant difference in Achilles Tendon Rupture Score at 9 months post injury (\u20131.38, 95% confidence interval \u20134.9 to 2.1). There was a statistically significant difference in Achilles Tendon Rupture Score at 8 weeks post injury in favour of the functional brace group (5.53, 95% confidence interval 2.0 to 9.1), but not at 3 or 6 months post injury. Quality of life showed the same pattern, with a statistically significant difference at 8 weeks post injury but not at later time points. Complication profiles were similar in both groups. Re-rupture of the tendon occurred 17 times in the plaster cast group and 13 times in the functional brace group. There was no difference in resource use.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec id=\"abs1-9\">\n                  <jats:title>Conclusions<\/jats:title>\n                  <jats:p>This trial provides strong evidence that early weight-bearing in a functional brace provides similar outcomes to traditional plaster casting and is safe for patients receiving non-operative treatment of Achilles tendon rupture. The probability that functional bracing is cost-effective exceeds 95% for the base-case imputed analysis, assuming a cost-effectiveness threshold of \u00a320,000 per quality-adjusted life-year. On average, functional brace is associated with lower costs (\u2013\u00a3103, 95% confidence interval \u2013\u00a3290 to \u00a384) and more quality-adjusted life-years (0.015, 95% confidence interval \u20130.0013 to 0.030) than plaster cast.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec id=\"abs1-10\">\n                  <jats:title>Limitations<\/jats:title>\n                  <jats:p>Some patients declined to participate in the trial, but only a small proportion of these declined because they had a preference for one treatment or another.
