Most people remember the moment clearly. A push-off playing tennis or soccer, a sensation like someone kicked them in the calf, and then the strange part: the leg just will not work. Nobody kicked you. That snap was your Achilles tendon letting go.
A rupture is different from the tendon pain described in the Achilles tendonitis article. The tendon has torn, partly or fully, and the question facing you and your surgeon is how to treat it. The good news buried in the research is that the tendon itself can heal well either way, what decides your outcome is the rehabilitation that follows.
Surgery, or no surgery?
A Canadian multicentre trial of 144 patients compared surgical repair against non-surgical care, with both groups following the same accelerated rehabilitation program, early weight-bearing and early movement in a boot. At two years there was no meaningful difference in strength, range of motion, or calf size between the groups. Re-ruptures were similar too (two after surgery, three without). The surgery group had more soft-tissue complications, mostly wound and scar problems.
That does not mean surgery is never the right call. The size of the gap in the tendon, your sport, your age, and how quickly you were seen all factor in. That decision belongs with you and your surgeon. Where we come in is everything after: whichever road you take, the rehab principles are the same, and doing them properly is what gets your push-off strength back.
The first weeks: boot and wedges
Early on, the ankle sits in a boot pointed down, toes away from you, often with heel wedges stacked inside. That position takes tension off the healing tendon. Over the following weeks the wedges come out one at a time and the foot gradually returns to neutral. Weight-bearing usually starts early, the research groups walked in the boot from the first weeks, but crutches help at first, especially around the house.
The mistakes we see most in this phase: rushing out of the boot because it feels fine, sleeping without it when the surgeon said to wear it, and the classic one, a slip in the shower that forces the foot flat. The tendon is healing but not yet strong. Respect the boot.
Rebuilding, month by month
Once you are out of the boot (often around eight to ten weeks, your surgeon decides), the real work starts. The calf on the injured side will look noticeably smaller, and single-leg heel raises are humbling at first. Rehab progresses in stages:
- Motion first: gentle ankle movement, scar care once the wound is fully closed, and normalising your walking pattern without a limp.
- Strength next: heel raises progress from two legs, to one leg, to weighted, over months, not weeks.
- Power last: hopping, jogging, and change-of-direction work come late, usually after six months, and only when strength testing says the leg is ready.
What recovery usually looks like
Honest answer: nine to twelve months to feel like yourself in sport again. Walking comfortably comes much sooner, driving depends on which leg and your surgeon’s instructions, and most desk work resumes within a few weeks. The heel raise, how high and how strong compared with your other side, is the milestone we watch most closely. Symmetry there is what protects you from doing it again.
When to call your surgical team
A new pop or sudden loss of push-off strength, wound redness or drainage, calf swelling with pain that is new or worsening, or any signs of infection, fever, spreading redness, should be reported the same day.
