An ACL recovery app for the whole road back.

Surgery or rehab without it, an ACL recovery runs for months: most people are back to full sport within 6 to 12 months of a reconstruction (AAOS). InjuryLog keeps all of it in one place: daily knee check-ins, the exercises your physio set, your MRI report and an estimated return window that sharpens as you go.

Free to start on iOS and Android.

How long ACL recovery usually takes

After an ACL reconstruction, from the NHS and AAOS. Typical ranges, not a promise for any one knee.

Weeks 0–2
Protect the knee, get it fully straight and switch the thigh muscle back on.
Weeks 2–6
Walking and movement come back. Many people return to work after about 4 to 6 weeks, depending on the job.
Months 2–4
Rebuild strength. Running comes back on your physio's plan, not on a set day.
Months 4–9
Hopping, landing and changing direction, added in stages.
Months 6–12
Most people return to full sport (AAOS). Pivoting and contact sports usually sit at the later end.

The full month-by-month guide · Managing a tear without surgery

Overview of a right knee ACL tear on day 203: pain down from 8 to 1 in 28 weeks, a return window of 5 February to 31 March with moderate confidence, and the next milestone, sprinting and change of direction.

Check in on the knee every day.

Twenty seconds: pain from 0 to 10, better or worse than last time, and the symptoms that matter after an ACL injury, like swelling, stiffness or the knee giving way.

Over months it becomes the story your memory can't hold: in this example, pain down from 8 to 1 across 28 weeks and steady for 38 days.

ACL rehab plan in phase 3 of 4, running and landing: pain during exercise 2 out of 10 and steady, 34 of 41 training days done in the last 6 weeks, and quad sets tagged as set by the physio.

Your physio's programme, phase by phase.

Add the exercises your physio prescribed, with sets, reps, holds and weights, grouped into the phases they set: settle and straighten, strength, running and landing, return to sport.

The player counts the reps, and you see how many training days you actually did and how sore the knee was during exercise, ready to talk through at your next session.

Notes and files for an ACL rehab plan: the physio's phase 3 plan in their words, a foam rolling video to do before every session, and the physio's exercise sheet as a PDF.

Your physio's plan, kept with the knee.

Write down what your physio told you, in their words, so "sore up to 3 out of 10, settled by the next morning" doesn't get lost between appointments.

Add their exercise sheets, videos of how to do each exercise and photos, all filed under the knee they belong to.

Recovery forecast for the right knee: the pain chart with a projected line and the typical recovery range, milestones set by the user from straight-line jogging to full training, and a note that this is not a clearance to return.

An estimated return window, not a promise.

Tell InjuryLog what you're working back to, football, hurling, running, skiing, and set your own milestones: straight-line jogging, sprinting and change of direction, drills, full training.

The Recovery Forecast shows an estimated window that updates with every check-in. Your surgeon and physio decide when you're ready; add the return date they gave you and the app plans around it.

Documents and scans for the right knee: GP referral letter, MRI of the right knee, orthopaedic consult letter, ACL reconstruction operation report and a 4-month physio progress report.

Every letter, scan and report in one place.

The GP referral, the MRI, the surgeon's consult letter, the operation report, every physio progress report: filed against the knee, in date order, findable in seconds.

Upload a report and get the written findings explained in plain English, with questions worth asking at your next appointment. Educational, not medical advice.

Progress for the right knee from 6 April to today: the pain line falling from about 8 to 1, with every physio visit and scan marked along the timeline, and the first milestone, walking pain free, ticked off.

Walk into every appointment prepared.

Pain, visits and scans on one line, so you and your physio can see what changed between appointments and what helped.

The Physio Visit Pack turns it into one page: how the knee has been since the last visit, your scans and your questions. Export it as a PDF or show it on your phone.

Comeback moments for an ACL recovery: the MRI on day 5, the knee in a brace on day 27, foam rolling on day 58 and the first run back on a pitch on day 197.

The road back, day by day.

Add photos as you go: the MRI, the brace, the first session in the gym, the first run back on the pitch. Each one is dated to the day of your recovery.

When you're ready, turn them into a comeback card to share, or keep them just for you.

What to look for in an ACL recovery app

An ACL rehab lasts long enough that the app has to be one you'll still open in month eight. These are the parts that matter.

  1. Works for surgery and for rehab without surgery. Partial tears and some full tears are managed with rehab; the tracking should fit both.
  2. Daily symptoms, not just exercises. Pain, swelling and the knee giving way tell you and your physio more than a ticked exercise list.
  3. Holds the plan your physio gives you. Your own exercises, sets and reps, rather than a generic programme.
  4. Keeps scans and reports with the injury. The MRI, the operation note and the physio letters, findable in seconds.
  5. Something to bring to appointments. A one-page summary beats scrolling back through weeks of notes.
  6. Timelines as ranges. Return to sport after a reconstruction is usually 6 to 12 months; an app that promises a date isn't being straight with you.
  7. Private by default. InjuryLog's data is encrypted, stored in the EU, never sold and never used for ads.

Questions

What is the best app for ACL recovery?

Look for one you will actually open every day that holds the whole recovery: daily knee check-ins (pain, swelling, giving way), the exercises your physio set, your MRI and surgeon reports, and a summary you can bring to appointments. InjuryLog does all of that in one app on iOS and Android, with an estimated return window that updates as you check in. It is educational recovery support, not medical advice: your surgeon and physio set the plan and decide when you are ready.

How long does ACL recovery take?

After ACL reconstruction, most people return to full sport within 6 to 12 months (AAOS), and the NHS says it can take up to a year to play sport again. Many return to work after about 4 to 6 weeks, depending on the job. These are typical ranges, not a promise for any one knee.

Can I track an ACL tear without surgery?

Yes. Log the injury on the body map, note how it was confirmed (for example an MRI), and check in daily while you do the rehab your physio prescribes. The same tracking works for a partial tear managed with rehab and for a reconstruction.

Does the app replace my physio?

No. InjuryLog records what is happening and helps you bring a clear picture to your physio and surgeon. It never diagnoses, never sets your rehab and never decides when you return to sport.

Is InjuryLog free?

It is free to start: log injuries on the body map, do daily check-ins and see your recovery status. Pro adds the Recovery Forecast, the full AI read of reports, analytics, the Physio Visit Pack, the Injury Vault and Care Costs. There is no free trial.
