Achilles tendon rupture: surgery or boot, and what recovery involves

The Achilles is the thick tendon that links the calf muscle to the heel. It usually ruptures during sudden push-off, with a feeling of being kicked in the back of the leg and difficulty rising onto the toes.

The Cambridge leaflet says conservative treatment in a boot is the main approach for most people, based on evidence that outcomes are similar to surgery without operative complications. Surgery is more likely when the injury is seen late, when the tendon has ruptured again, or in some high-level athletes.

The practical message is that either route requires a long commitment and that neither is a quick fix.

Initially you will be given crutches and a boot with wedges that keep the foot pointing down. If you are having surgery, pre-assessment covers medicines, anaesthetic and fasting. Stopping smoking improves wound healing, and it is worth telling the team if you have diabetes or take blood thinners.

Plan transport and work: driving is restricted for weeks, and you may be sleeping in the boot.

If surgery is chosen, the two torn ends of the tendon are stitched back together through an incision at the back of the leg, or by a smaller technique. You are usually allowed home the same day, with a boot or cast.

The boot period afterwards is described by trusts as similar to non-operative care. The surgical route adds a wound and its risks, so the benefit is mostly a possible lower re-rupture risk in some patients.

The main risk with either approach is re-rupture. Cambridge says vulnerability is highest in the first six weeks after the boot comes off, and Plymouth warns that re-injury is most likely in the first eight weeks after coming out of the boot. Surgery adds wound infection, scar problems and nerve irritation. Both routes carry a risk of clots in the leg, and Cambridge asks you to watch for sudden calf or thigh cramp, chest pain, breathlessness, more swelling or numbness.

Cambridge describes weeks zero to four with three wedges, weeks five to seven with wedges removed one at a time, and from week eight onwards a move to supportive footwear with a heel pad. You can put weight through the whole foot in the boot.

Plymouth describes physiotherapy stages: strengthening of the quadriceps and hamstrings from week three, calf contractions from week four, balance work from week eight, single-leg heel raises and cautious jogging at four to six months, and sport-specific training from six to twelve months.

Work return ranges from about two weeks for desk work to twelve to sixteen weeks for physical roles in the Cambridge leaflet. Full recovery can take well beyond a year.

• Sudden calf or thigh cramp, increasing swelling or numbness: seek urgent medical help.

• Chest pain or breathlessness: call 999.

• A new sudden pop or loss of push-off strength after the boot comes off.

• Wound redness, heat or discharge if you have had surgery.

• Why do you recommend a boot or surgery in my case?

• How soon after injury was the diagnosis made, and does that change the plan?

• How many weeks of boot and what is the wedge schedule?

• When can I drive, given which leg and which car I have?

NHS rupture clinics often start with a boot protocol and reserve surgery for particular cases, in line with the leaflets above. Private care may be more ready to offer surgery. Ask whichever route you use about the evidence for your own situation, the expected rehabilitation and who supervises it.
