Holger Rune Undergoes Successful Achilles Surgery, Faces Long Layoff

Expert voices differ on what the enforced break could mean for his development.

Overview

Rune ruptured his left Achilles tendon during the Stockholm Open semifinal against Ugo Humbert and retired from the match in tears.
He confirmed the tendon was fully broken on the proximal part and said the operation was required promptly after the injury.
Rune reported that the surgery went really well and indicated he is beginning a lengthy rehabilitation before returning to competition.
Reporting indicates he is expected to be sidelined for several months, with projections that he could miss most of the 2026 season.
Former coach Patrick Mouratoglou called the layoff a chance to build mental and tactical strength, while Sam Querrey cautioned it may take up to two years to fully regain confidence in movement.
