Rupture vs. Calf Strain
A full Achilles rupture is a complete tear of the tendon connecting your calf muscles to your heel — often felt as a sudden pop, or like being kicked in the back of the leg. It's different from a calf muscle strain (sometimes called “tennis leg”), which is a tear within the muscle itself and usually recovers faster, closer to the timeline in our muscle strain and sprain guide. This handout covers the rupture, which needs a longer, more structured rehab.
Surgical or Conservative — Both Can Work
Research shows surgical repair and conservative, boot-based treatment lead to similar functional outcomes at one year. Non-surgical care carries a slightly higher risk of re-rupture; surgery carries a slightly higher risk of complications. The right choice depends on your goals, activity level, and your surgeon's guidance.
Your Rehab Roadmap
Weeks 0–8: Protection — a supportive boot with gradual heel-lift changes, gentle motion, and early isometrics.
Weeks 6–12: Normalize walking — transitioning out of the boot and walking confidently without a limp.
Weeks 8–12+: Build strength — progressive heel raises, single-leg work, and general strength training.
Week 12+: Power & running — jumping and running introduced once you meet specific strength benchmarks.
Months 4–6+: Return to sport — sport-specific drills, with full return guided by strength testing, not the calendar.
What the Research Shows
A few things worth knowing going in:
Full functional recovery often takes 12 months or longer
Reaching about 85% strength compared to your other leg is a common benchmark before full return to sport
Consistency with your rehab program matters as much as which initial treatment you chose
Bottom line: An Achilles rupture is a serious injury, but not a career-ending one. With a structured, patient rehab process, most people return to running, jumping, and the activities they love.
