Recovery timeline
Recovery After ACL Surgery
ACL reconstruction is a day-case operation, but the surgery is really just the starting line — your knee is rebuilt by the months of physio that follow. Here is what a typical recovery looks like, milestone by milestone.
The short version
When can I… — your recovery at a glance
Crutches & brace
Off crutches typically within 2 to 4 weeks once you can walk without a limp; a brace (if used) is often worn for the first 4-6 weeks.
You may be allowed to put weight through the leg straight away — follow the specific weight-bearing rule you're given, especially if the meniscus was also repaired.
Showering & the wound
You can usually shower with the wound covered and kept dry from about 48 hours; soaking in a bath or pool waits until it's fully healed, often 2-3 weeks.
Keep dressings dry until steri-strips or stitches are removed (around day 10-14); a little bruising tracking down the shin is normal after a graft.
Driving
Left knee with an automatic car can be as early as 2 weeks; a right (operated) knee or a manual is usually closer to 6 weeks.
Only drive once you're off opioid painkillers, out of the brace and can stamp on the brake hard without hesitation — test it stationary first.
Returning to work
Desk and home-working jobs typically 1 to 2 weeks; jobs on your feet, climbing or heavy lifting can take 3 to 6 months.
Even at a desk, keep the leg elevated and take walking breaks early on to settle swelling and lower clot risk.
Flying
Short hops may be fine after a week or two, but most surgeons advise waiting 4 to 6 weeks before longer flights.
Fresh surgery plus long-haul immobility raises DVT risk — move your ankles, walk the aisle and wear compression stockings if you must fly early.
Running & exercise
Light cycling and pool work start within weeks; straight-line jogging usually returns around 3 to 4 months once strength and control are tested.
Running is earned through objective strength and stability tests, not the calendar — going early is the commonest setback.
Sex & intimacy
Most couples resume gently within 2 to 4 weeks, guided by comfort, swelling and positions that don't strain or twist the knee.
Avoid putting your full body weight through a bent operated knee until your physio says the graft can take it.
Return to pivoting sport
Football, netball, basketball, skiing and other cutting sports typically come back at 9 to 12 months — and only once you're formally cleared.
Returning before 9 months and without passing return-to-sport testing sharply increases the risk of re-tearing the new graft.
What affects how fast you heal
- How consistently you do your physio — it is genuinely the single biggest driver of how your knee turns out, far more than the operation itself.
- Getting full straightening (extension) and the swelling down in the first few weeks; a stiff knee early slows everything that follows.
- Whether the meniscus or cartilage was also repaired — that often means a slower, more protected start and a later return to running and sport.
- Your age, fitness and goals: a recreational walker is back to normal life far sooner than a competitive pivoting athlete chasing a full return.
Call your surgeon or seek urgent care if…
- A hot, increasingly swollen or red knee, wound discharge or pus, or a fever above 38C — signs of infection that need same-day advice.
- Calf pain, tenderness, swelling or warmth, especially one-sided — possible DVT (blood clot) that must be checked urgently.
- Sudden breathlessness, chest pain or coughing blood — a possible clot on the lung; call emergency services immediately.
- Bleeding that soaks through the dressing, or rapidly increasing tense swelling and severe pain not eased by your usual painkillers.
- New inability to straighten or bend the knee, or a sudden giving-way, pop or feeling the graft has failed.
What to ask your team before you go home
- Can I put full weight through the leg, and do I need to wear the brace locked or unlocked — and for how long?
- When does my physio start, and what exercises should I be doing every day before that first appointment?
- How long should I take the blood-thinner or wear compression stockings to prevent clots, and what painkillers should I use?
- When do the stitches or dressings come off, who removes them, and what's the date of my surgical follow-up?
Frequently asked questions
When can I drive after ACL surgery?
It depends on which knee and which car. With an automatic and a left-knee reconstruction, some people drive at around 2 weeks. For the right (operated) knee, or a manual gearbox, it's usually nearer 6 weeks. Whichever applies, only drive once you're off opioid painkillers, out of the brace, and can hit the brake firmly and confidently. Test an emergency stop while parked first.
When can I go back to work?
If you have a desk or home-based job, most people return within 1 to 2 weeks, keeping the leg up and taking regular breaks. If your work involves being on your feet all day, ladders, kneeling or heavy lifting, expect 3 to 6 months — your knee needs real strength and stability first. A phased or lighter-duties return often helps you get back sooner and more safely.
When can I run and play sport again?
Light jogging in a straight line typically returns around 3 to 4 months, but only after you pass strength and control checks. Pivoting sports such as football, netball, basketball and skiing usually wait until 9 to 12 months and require formal clearance. Returning early, before nine months and without passing return-to-sport testing, markedly raises the chance of re-tearing your new ACL graft.
When can I fly after ACL reconstruction?
Short domestic flights may be reasonable after a week or two if you're moving well, but most surgeons suggest waiting 4 to 6 weeks for longer or long-haul journeys. The concern is deep vein thrombosis — a blood clot — because recent surgery and hours of sitting still both raise the risk. If you must fly early, keep your ankles moving, walk the aisle regularly, stay hydrated and wear compression stockings.
