This Level I multicenter RCT randomized 144 patients with acute Achilles tendon rupture to operative repair or nonoperative management. Both groups underwent identical accelerated functional rehabilitation with early weight-bearing and range of motion. The study asks whether surgery adds any benefit when rehabilitation — not immobilization — is the baseline treatment.
The conventional argument for surgery in Achilles rupture rested on a 2002 meta-analysis showing a relative risk of rerupture of 0.32 favoring repair — but every study in that analysis used 6–8 weeks of cast immobilization as the comparator, not functional rehabilitation.
This trial dismantles that premise. When you put both groups in a functional brace with early weight-bearing, rerupture rates are identical and every patient-reported outcome converges by 2 years.
When you see a healthy adult with an acute Achilles rupture, nonoperative treatment in a pneumatic walking brace with early weight-bearing is a defensible first-line choice. Reserve surgery for patients who cannot reliably comply with a functional rehabilitation protocol. Not as a default to prevent rerupture.
The one nuance worth knowing: surgery retains a small advantage in high-speed (240°/s) isokinetic plantar flexion strength at 2 years. For a competitive sprinter or jumper, this may matter. But for most recreational athletes, the complication risk of surgery outweighs this marginal gain.
