Direct answer
Return to pivoting sport usually comes 9 to 12 months or more after ACL reconstruction, once testing shows the knee is ready. Everyday milestones come much sooner:
- Crutches: about 1 to 6 weeks
- Desk work: about 1 to 2 weeks; work on your feet, 4 to 6 weeks
- Driving: about 2 to 3 weeks after left-knee surgery or 4 to 6 weeks after right-knee surgery, once you can brake hard
- Light jogging: around 3 to 4 months
- Very physical work: about 4 to 6 months
- Pivoting sport: 9 to 12+ months, after passing return-to-sport tests
These are typical ranges. Your graft, any other work done in the knee, and your progress in rehabilitation all move the dates. Your surgeon’s protocol comes first.
This guide covers recovery after ACL reconstruction, the operation that replaces a torn anterior cruciate ligament with a tendon graft. Use the ranges below to plan work, travel and family commitments, then follow the plan your surgeon and physiotherapist set.
The ACL recovery timeline at a glance
Phases overlap. Many rehabilitation programs move you forward once you meet goals for swelling, range of motion and strength, and use time since surgery as a minimum. The Aspetar clinical practice guideline recommends this criteria-based approach for the whole rehabilitation program.
| Phase | Typical timing | Main focus | Common milestones |
|---|---|---|---|
| Pre-hab | Before surgery | Settle swelling, fully straighten the knee, activate the quadriceps, walk without a limp | A stronger, quieter knee going into surgery |
| Protect and activate | Weeks 0–2 | Ice, elevation, full straightening, thigh-muscle activation, weight-bearing as instructed | Crutches; brace if prescribed; first follow-up visit around two to three weeks |
| Walk normally | Weeks 2–6 | Wean off crutches, increase knee bend, stationary bike, basic strength work | Off crutches; desk work; driving; work on your feet from about 4–6 weeks |
| Build strength | Weeks 6–12 | Progressive leg strength, balance and movement control | Normal walking; avoid strenuous activity until about 12 weeks |
| Run and land | Months 3–6 | Running progression, hopping and landing drills | Light jogging around 3–4 months once criteria are met; running or cycling around 4–6 months; physical work from about 4 months |
| Train for sport | Months 6–9 | Agility, change of direction, sport-specific drills | Return-to-sport testing guides the next step |
| Return to pivoting sport | Months 9–12+ | Graded return from team training to competition | Full sport after passing return-to-sport tests; ongoing strength work |
Before surgery: pre-hab
Pre-hab is the rehabilitation you do between injury and operation. The goals are a settled knee, full straightening, good quadriceps activation and a normal walking pattern. The Aspetar guideline reports that preoperative rehabilitation can improve early knee motion and quadriceps strength at three months after surgery, and might shorten the time to return to your pre-injury activity level. If you are waiting for surgery, this phase puts that time to use. Our guide to ACL surgery wait times in Canada covers the access side.
Weeks 0 to 2: protect and activate
Swelling, bruising and a weak thigh are common in the first days. The Aspetar guideline recommends starting active knee movement right away and progressive weight-bearing in the first week, adjusted to your surgeon’s instructions. Keep the knee straight when resting: MyHealth Alberta aftercare guidance advises a pillow under the foot, and the NHS advises against a pillow under the knee. The NHS also describes a first follow-up about 2 to 3 weeks after surgery.
Weeks 2 to 12: walk, then build
Most people walk without crutches during this stretch and move on to strength, balance and control work. MyHealth Alberta advises avoiding strenuous activity for about 12 weeks, including mowing, raking and shovelling snow.
Months 3 to 12: run, train, return
Later rehabilitation adds running, hopping, landing and change-of-direction drills. Progress here depends on strength and movement control, so two people with the same surgery date can be months apart.
When can you drive, work and run after ACL surgery?
How long will I need crutches and a brace after ACL surgery?
Most people use crutches for about 1 to 6 weeks. A meniscus repair or cartilage procedure can change the weight-bearing plan. Some surgeons use a brace for roughly 2 to 6 weeks, and some use none. Stop using either one when your surgeon or physiotherapist tells you to.

When can I drive after ACL surgery?
Drive once you can brake hard in an emergency, you are off crutches, and you have stopped prescription pain medicine. A clinical practice guideline puts this at roughly 4 to 6 weeks after right-knee surgery and 2 to 3 weeks after left-knee surgery. A manual car also needs your left leg for the clutch. Confirm with your surgeon before your first drive.

When can I go back to work after ACL surgery?
It depends on the job. Alberta’s provincial health site gives about 1 to 2 weeks for seated work, 4 to 6 weeks for work on your feet, and 4 to 6 months for very physical work. A 2024 systematic review found most people returned to work within about 90 days of surgery.
If your role involves kneeling, ladders or heavy lifting, ask about a graded return or modified duties. Sources: MyHealth Alberta, Özbek et al., 2024.
When can I start running after ACL surgery?
Many programs start light jogging around 3 to 4 months, and Alberta’s provincial health site says most people can jog at about 4 months. An international rehabilitation guideline suggests meeting criteria first, including full knee straightening, close to full bend, little or no swelling, and quadriceps strength above 80% of the other leg.
Sources: MyHealth Alberta, Aspetar guideline.
When can I return to sport after ACL surgery?
Return to pivoting sports such as soccer, basketball, hockey and skiing usually comes at 9 to 12 months or later. AAOS patient guidance says most patients are allowed to return to full sports within 6 to 12 months, depending on progress, strength and mechanics. Alberta’s provincial health site says most people can run or cycle at about 4 to 6 months.

Why testing guides the return to sport
Time matters because the graft needs a minimum period to heal. Time alone says little about whether the leg is ready for cutting and landing. The Aspetar guideline treats time since surgery as one requirement that works alongside objective physical and psychological criteria. Common tests include:
- Quadriceps and hamstring strength, compared with the other leg
- Single-leg hop and jump tests for distance, height and control
- Range of motion and swelling
- Questionnaires on knee function and confidence
- Movement quality during running, landing and change of direction
The evidence is still developing. In the Delaware-Oslo cohort of 106 athletes in pivoting sports, the reinjury rate fell by 51% for each month return to sport was delayed, up to 9 months after surgery. Of those who failed return-to-sport criteria, 38.2% were reinjured, compared with 5.6% of those who passed; that pass/fail difference fell short of statistical significance in a small study. More symmetrical quadriceps strength before return did significantly lower the reinjury rate.
How common is a second ACL injury?
A second ACL injury is the outcome most late-stage rehabilitation aims to prevent. A 2016 meta-analysis found a combined second-injury rate of 15%: 7% to the reconstructed knee and 8% to the other knee. For athletes under 25 who returned to sport, the rate was 23%, close to 1 in 4.
Return rates vary too. A meta-analysis of 69 studies found that, on average, 81% of people returned to some sport, 65% to their pre-injury level and 55% to competitive sport. Symmetrical hop performance, younger age, elite-level sport and a positive psychological response favoured a return to the pre-injury level.
Does graft choice change recovery time?
Graft choice mainly shapes some symptoms and rehabilitation details. A Cochrane review found no clear difference in return to activity between patellar tendon and hamstring grafts. Grafts can come from your own patellar tendon, hamstring or quadriceps tendon, or from a donor. Pathway’s ACL reconstruction page describes the graft options our surgeons use.
- Patellar tendon (bone–patellar tendon–bone). The Cochrane review found more stable knees on examination and more front-of-knee problems, especially with kneeling.
- Hamstring tendon. The same review found a loss of knee-bending (flexion) strength. A meta-analysis of 47,613 reconstructions found hamstring grafts ruptured slightly more often than patellar tendon grafts, with low failure rates in both groups.
- Quadriceps tendon. A graft taken from above the kneecap. Ask your surgeon how it compares for your knee and sport.
- Donor tissue (allograft). In a multicentre cohort of 2,683 patients, donor grafts carried higher odds of re-tear than patellar tendon grafts. Younger age and higher activity levels also raised the risk.
How is recovery after ACL repair different?
ACL repair reattaches your own ligament in selected tears, usually close to the thigh-bone attachment. Your surgeon may adapt early rehabilitation to protect the healing ligament. Pathway’s ACL repair page describes an overall timeline comparable to reconstruction, and later milestones still rely on strength and function testing. Our ACL repair vs. reconstruction guide covers candidacy and the evidence.
What can change your ACL recovery time?
- Other injuries treated at surgery. Meniscus or cartilage work can change weight-bearing, bracing and the early plan. The Aspetar guideline adapts early rehabilitation to the surgeon’s instructions in these cases.
- Swelling and strength. Ongoing swelling or slow quadriceps recovery holds back running and sport, because both appear in progression criteria.
- Pre-hab. Better motion and strength before surgery can carry into the early months after it.
- Rehab follow-through. MyHealth Alberta links the return to sport with how well you follow your rehab program and how well the knee heals.
- Age and sport. Younger athletes returning to high-level sport carry the highest second-injury risk, one reason surgeons weigh age and sport when planning the return.
- Confidence. The Aspetar guideline identifies psychological factors, particularly fear of reinjury, as the most significant contributors to people missing a return to sport.
- Job demands. Seated work returns in weeks; physical work can take months.
Warning signs: when to call your care team
Contact your surgeon’s office or care team right away, or call your provincial nurse line (811 in most provinces and territories), if you notice:
- Pain that stays the same or worsens after you take pain medicine
- Tingling, weakness or numbness in your foot or toes, or a foot that turns cool, pale or changes colour
- Signs of a blood clot: pain in the calf, back of the knee, thigh or groin, or redness or swelling in the leg
- Signs of infection: increasing pain, swelling, warmth or redness; red streaks from the incision; pus; or a fever
- Bleeding through the bandage, loose stitches, or an incision that opens
Call 911 if you faint, have chest pain or shortness of breath, or cough up blood. This list follows MyHealth Alberta aftercare guidance.
Questions to ask your surgeon
- Which graft do you recommend for me, and why?
- Will you treat the meniscus or cartilage, and how would that change weight-bearing or bracing?
- Will I use a brace, and for how long?
- When can I drive, given which knee you are operating on?
- When can I return to my job, and would modified duties help?
- Which tests will you use before I run, cut or return to sport?
- What would make you slow my plan down?
