The purpose of this study was to evaluate calf muscle endurance in a seated position 3 months after an A chilles tendon rupture and to evaluate how the ability to perform standardized seated heel‐rises correlated to the single‐leg standing heel‐rise test and to patient‐reported symptoms evaluated with the A chilles tendon T otal R upture S core ( ATRS ) 3 and 6 months after the injury. Ninety‐three patients were included from a cohort of 101 patients participating in a prospective, randomized controlled trial comparing surgical and nonsurgical treatment after A chilles tendon rupture. Forty‐seven patients were treated surgically and 46 nonsurgically. Ninety‐one patients out of 93 (98%) could perform the standardized seated heel‐rises. At the 3‐month follow‐up, there was a significant difference ( P < 0.001) between the injured and the healthy side performing standardized seated heel‐rises. There were also significant correlations ( r = 0.29–0.37, P = < 0.05) between the standardized seated heel‐rises and ATRS 3 and 6 months after injury in the group who could not perform single‐leg standing heel‐rises. There were no significant differences between the surgical and nonsurgical treatment groups. The evaluation of standardized seated heel‐rises appears to be a useful tool to quantify progress and predict future functional performance and patient‐reported symptoms.
