This is a general guide. Your operation record and the instructions you are given always take precedence over anything written here. Last reviewed 5 August 2026.
Two very different recoveries come out of the same keyhole operation. Your operation record says whether the torn piece was TRIMMED (partial meniscectomy: see the partial meniscectomy guide) or STITCHED (meniscal repair. This guide). If you are not sure which you had, call the rooms before following any timeline here. Patients frequently do not know which was done until they wake up, because the decision is made once the surgeon sees the tear, and the two timelines are weeks apart.
If the stitched guide is yours, your meniscus was worth saving, and the next few months are about protecting that investment. A hinged brace limits the bend, crutches share the load, and deep bending and twisting are off the menu while the stitches hold the tear together and it slowly heals. The restrictions in this guide are not caution for its own sake: they are the treatment.
One more check before you start. If a cartilage repair (microfracture, MACI, osteochondral graft) was performed, this guide does not apply: those pathways involve 6–8 weeks of protected weight bearing and 9–12 months before impact sport. Call the rooms for the specific protocol.
Every timeframe in this guide is typical, not a rule. Repairs differ, where the tear was, what pattern it had, and how it was stitched all change the plan, and root and radial repairs run slower. Dr Broadhead’s instructions for you always override the general figures here.
The meniscus is a C-shaped cushion of fibrous cartilage between the thigh bone and the shin bone: a shock absorber and load spreader. Each knee has two, and losing one substantially raises the long-term risk of arthritis in that part of the knee. That is why a repairable tear gets repaired.
In a knee arthroscopy, the surgeon works through two or three small keyhole cuts using a camera and fine instruments. In a meniscal repair, the torn edges are held back together with stitches or anchor devices so the tear can heal. Some repairs are at the meniscal root, where the meniscus anchors to the bone, and these are reattached to the bone itself; root and radial repairs are the slowest healers and carry the most cautious timelines.
Here is the biology that drives everything in this guide: only the outer quarter or so of the meniscus has a blood supply, so a stitched meniscus heals slowly: three months and more. Early deep bending and twisting shear the repair. Protecting it now buys you a meniscus for life; a failed repair means another operation and a higher long-term risk of arthritis.
Trimmed and stitched are different operations with timelines weeks apart, done through identical keyholes. This guide is for a STITCHED (repaired) meniscus only. If your operation record says the torn piece was trimmed away, stop here and use the partial meniscectomy guide, and if you are not sure, call the rooms before following any timeline.
A repaired meniscus often feels good long before it is healed. Only the outer quarter or so of the meniscus has a blood supply, so healing takes three months and more, and early deep bending and twisting shear the repair regardless of how the knee feels. The brace, the crutches and the precautions are the treatment. Protecting the repair now buys you a meniscus for life; a failed repair means another operation and a higher long-term risk of arthritis.
Swelling switches the quadriceps off. This is universal and expected, not a sign anything went wrong. It happens by reflex whenever a knee joint swells. Quadriceps work starts on day one, inside the brace: static quadriceps sets and straight leg raises, little and often, from the recovery room onwards.
Where the tear was and how it was stitched change the plan. Root and radial repairs commonly mean touch weight bearing for 4–6 weeks and a longer road back to pivoting sport. Your discharge letter and reviews set your version of the timeline. The figures in this guide are the typical frame around them.
If a cartilage repair (microfracture, MACI, osteochondral graft) was performed, this guide does not apply: those pathways involve 6–8 weeks of protected weight bearing and 9–12 months before impact sport. Call the rooms for the specific protocol.
Weight bearing
Protected weight bearing with crutches for 2–6 weeks, set by the repair type
Unlike a meniscectomy, a repaired meniscus needs protecting from load while it heals. You will use crutches for somewhere between 2 and 6 weeks. Your discharge letter says exactly what your repair allows.
Root and radial repairs commonly mean touch weight bearing (the foot rests on the ground for balance only) for 4–6 weeks, because these repair types are the most vulnerable to load.
The brace stays on for walking throughout this period, and weight bearing is progressed at your reviews, not by feel. A knee that feels fine at week three is not evidence the repair has healed.
| Stage | Typical timing | Move on when |
|---|---|---|
| Two crutches, brace on, weight bearing as your repair allows | From day 0 | As set on your discharge letter: touch weight bearing for 4–6 weeks is common for root and radial repairs |
| Weaning from two crutches to one, then none | Between 2 and 6 weeks, per your repair type | Cleared at review; walking without a limp in the brace |
| No aids, brace range unlocked | From 4–6 weeks, as advised at review | Cleared at review; comfortable, quiet knee |
Only the outer quarter or so of the meniscus has a blood supply, so a stitched meniscus heals slowly: three months and more. Early deep bending and twisting shear the repair. Protecting it now buys you a meniscus for life; a failed repair means another operation and a higher long-term risk of arthritis.
| Rule | Why | How to manage |
|---|---|---|
| No squatting past 90 degrees | Deep knee bending under body weight squeezes and shears the back of the meniscus: exactly where many repairs sit. | Squat only to a right angle, and only when your phase allows loaded work. Use higher chairs and avoid low couches early on. |
| No kneeling | Kneeling forces the knee into deep, loaded flexion and drives the thigh bone back against the repair. | For floor-level tasks, sit on a low stool or the floor with the operated leg out in front instead. |
| No lunging | A deep lunge loads the meniscus through a large arc of bend, shearing the healing tear. | Keep strength work within the ranges set for your phase: shallow, controlled, both feet planted. |
| No pivoting or twisting for 3–4 months | Rotation of the shin under load is the exact mechanism that tears menisci, and re-tears repairs. | Turn with small steps rather than spinning on a planted foot. No cutting, sidestepping or racquet-sport movements until cleared. |
| Period | Instruction |
|---|---|
| Weeks 0 to 4–6 | Worn whenever you are up on your feet: standing and walking. Follow the instructions given at fitting for rest and sleep, which vary with the repair. |
| From 4–6 weeks | The range is unlocked and the brace is weaned as advised at your review. |
| Period | Permitted range |
|---|---|
| Weeks 0 to 4–6 | 0–90 degrees, set on the dial: full straightening allowed, bend capped at a right angle |
| From 4–6 weeks | Progressively unlocked at review, as your repair allows |
| Milestone | Earliest (weeks) | Typical | Latest |
|---|---|---|---|
| Brace fitted; crutch walking, weight bearing per repair type | 0 | 0 | 1 |
| Wound review | 2 | 2 | 3 |
| Crutches weaned (2–6 weeks; root/radial repairs at the later end) | 2 | 4 | 6 |
| Brace range unlocked at review | 4 | 5 | 6 |
| Clinical review with X-ray, brace range reassessed | 6 | 7 | 8 |
| Stationary cycling | 6 | 7 | 9 |
| Full range of movement rebuilt | 8 | 10 | 12 |
| Loaded deep bending and twisting restrictions lifted (3–4 months) | 13 | 15 | 17 |
| Running (quiet knee, strength gates met) | 13 | 15 | 17 |
| Pivoting sport (longer for root repairs) | 17 | 22 | 26 |
You move to the next phase by meeting its exit criteria, not by the calendar. The week numbers are typical, nothing more.
Guard the repair: brace on, crutches as prescribed, swelling controlled, and the quadriceps switched back on from day one.
Ready for the next phase when…
Move within the brace limit: build the bend towards (never past) 90 degrees, keep the quadriceps working, and wean the crutches as your repair type allows.
Ready for the next phase when…
With the brace range unlocked, rebuild full movement and real strength, still without loaded deep bending, pivoting or twisting.
Ready for the next phase when…
Earn the way back: running from about 3–4 months on a quiet knee with the strength gates met, pivoting sport from about 4–6 months: later for root repairs.
Ready for the next phase when…
Little and often beats one heroic session. Each exercise lists what you should feel, sharp pain that lingers afterwards means ease off and, if it persists, call.
Keep blood moving in the calf while you are on crutches and less active than usual.
10 firm pumps, every waking hour, for the first 2 weeks
Feel: You should feel the calf muscles working. The brace does not limit the ankle: move it fully.
Switch the thigh muscle back on: swelling turns it off in every knee, and everything else depends on it.
10 holds of 5 seconds, 3–4 times daily, from day one
Feel: You should feel this in the front of the thigh. A weak, flickery contraction on day one is normal. It sharpens quickly.
Quadriceps strength with the knee held straight: completely safe for the repair.
10 lifts, hold 3 seconds, 3 times daily
Feel: If the knee sags as you lift (a "lag"), keep working the static quads. The lag going is the sign of progress.
Keep the knee fully straight: the brace allows it, and losing straightening is the avoidable complication.
5 minutes, 2–3 times daily
Feel: A gentle stretch behind the knee is right. Never rest with a pillow under the knee.
A smooth, safe walking pattern that keeps the load on the repair exactly where it should be.
Every walk, until weaned at review
Feel: For touch weight bearing, the foot rests on the ground for balance only, like standing on a bathroom scale you are not allowed to move past a few kilograms.
Build the bend gradually towards, never past: the 90-degree limit.
10 slow slides, 3 times daily
Feel: Stop short of 90 degrees every time. The limit is a wall, not a target to touch at speed. A towel under the heel makes it slide easier.
Progress the bend within the permitted range using gravity and the other leg.
10 bends, hold 5 seconds, 3 times daily
Feel: A right angle at the knee is the absolute ceiling in this phase: work below it, not at it.
Quadriceps strength in the safest part of the range: small bend to full straight.
2–3 sets of 10, hold 3 seconds, once or twice daily
Feel: The knee stays on the roll throughout, only the heel lifts. You should feel the lowest part of the thigh, just above the kneecap.
Keep the kneecap and the portal scars gliding freely while the range is restricted.
1–2 minutes in each direction, twice daily, once the dressings are off
Feel: It should feel odd, not painful.
Soften and desensitise the small portal scars once fully healed.
2–3 minutes, twice daily, once healed and dry
Feel: Firm enough to move the skin; it should not be painful.
Range, circulation and endurance with almost no shear on the repair: the workhorse of Phase 3.
10–20 minutes, most days, once the bend allows a full revolution
Feel: The knee should feel looser after a ride, not hotter and tighter.
Real-world leg strength through a safe range.
2–3 sets of 8–10, once or twice daily
Feel: Share the load evenly between the legs.
Harder: Slow the lowering phase; shift more weight to the operated side over time.
Thigh and hip strength: always inside the loaded-bending rule.
2–3 sets of 10 to about 45 degrees, once or twice daily
Feel: Shallow on purpose: loaded squatting past 90 degrees stays off the menu until 3–4 months.
Calf strength for a normal push-off and, later, running.
2–3 sets of 10, once or twice daily
Feel: Even weight through both feet.
Harder: Single-leg raises on the operated side.
Single-leg strength for stairs, slopes and the running program ahead.
2–3 sets of 8 each leg, once daily
Feel: Push through the whole foot; keep the knee tracking over the toes, not diving inward.
Harder: Raise the step height, then reduce hand support: keeping the knee bend under 90 degrees.
Joint control and steadiness: the foundation for the return to running and, eventually, pivoting.
Build to 3 holds of 30 seconds each leg, daily
Feel: Quiet foot, tall posture.
The braking strength that controls descents and deceleration: essential before change-of-direction work.
2–3 sets of 8 each leg, alternate days
Feel: Slow and controlled beats deep; keep the pelvis level.
Active hamstring and bend strength through range, unloaded.
2–3 sets of 10, once daily
Feel: Keep the knees level with each other; move only below the knee.
Follow the instructions given at your brace fitting about whether the brace stays on in bed. This varies with the repair, so your discharge letter wins.
If you want the leg supported, place a pillow under the whole lower leg from calf to heel so the knee stays straight, never a pillow under the knee itself.
Side sleeping with a pillow between the knees is usually comfortable once the early soreness settles; keep the operated knee within its permitted range.
Disturbed sleep in the brace phase is common and temporary. Ice before bed and timing pain relief for the night both help.
Pain after a meniscal repair is usually front-loaded: the first days need regular pain relief, then it tapers to occasional simple analgesia. Discomfort from the brace and crutches is often as noticeable as the knee itself.
Take pain relief ahead of your exercise sessions rather than chasing pain afterwards, and come off the strongest medication first.
Routine blood thinners are not used for low-risk day-case arthroscopy. The clot risk is low and the trials do not support routine medication. Your individual risk factors (previous clots, some medical conditions and medications, long travel plans, and the longer period on crutches) are assessed, and if you need prevention it will be prescribed specifically.
A key warning: a repaired knee often feels good well before it is healed. Low pain at week three is welcome, but it is not permission to bend, load or twist: the stitches, not the pain, set the pace.
You may drive when all of the following are true:
What the research actually measures is braking reaction time on a simulator. Those studies show braking performance returns to its pre-operative level at about 2 weeks after a right hip replacement and about 4 weeks after a right knee replacement, with movement time back to normal by 6 weeks. After knee arthroscopy the simulator evidence is more conservative than common practice: in the one study that measured it directly, braking was still slower one week after surgery than before it, and had recovered by four weeks, and a 2021 review of eight studies put the average return at about six weeks. Most people having a simple arthroscopy are driving well before that, which is why the criteria above matter more than the date. But these are averages, in one study, about one in three right-hip patients still could not meet an emergency-stop benchmark at six weeks. Treat the timeframes in this guide as targets for discussion with us, not as permissions.
No published study has compared automatic and manual cars. The logical point is simply that a manual needs the left leg for the clutch, so left-sided surgery is the relevant caution in a manual. Advice about driving earlier with a left-leg operation in an automatic is clinical judgement, not trial evidence.
In Australia, your treating doctor’s advice governs: under the Austroads "Assessing Fitness to Drive" standards, temporary post-operative impairment is a matter of clinical judgement, and commercial drivers are held to a higher standard. Driving while impaired may invalidate your insurance, check your insurer’s position. Do not drive for at least 24 hours after any general anaesthetic or sedation.
| Activity | Typical | When it’s right | Notes |
|---|---|---|---|
| Walking (brace and crutches) | From day 0 | Weight bearing exactly as your discharge letter sets | Root and radial repairs commonly touch weight bearing for 4–6 weeks |
| Desk work | Individually advised, often early, on crutches | Off strong pain relief; transport sorted (you cannot drive in the brace) | Elevate the leg under the desk; short walking breaks hourly |
| Driving | Deferred while in a range-limiting brace | Out of the brace, off strong pain relief, able to emergency-stop at full force: see the driving criteria | Discussed at the review where the brace comes off |
| Swimming | After the brace phase, once cleared | Wounds fully healed; brace range unlocked; ask at review first | Avoid whip-kick (breaststroke) until the twisting restriction lifts at 3–4 months |
| Stationary cycling | From about 6 weeks | Brace range unlocked; bend allows a full revolution | Saddle high at first |
| Gym strength work | Weeks 6–12 | Within the precautions, no loaded bending past 90°, no lunges, no pivoting | Shallow, controlled, progressive |
| Physical work | Individually planned | Depends on kneeling, squatting, ladder and lifting demands: the 3–4 month restrictions apply | Raise it early at review so modified duties can be arranged |
| Running | From about 3–4 months | Quiet knee (no swelling reaction); strength gates met; cleared at review | Straight-line first, built in stages |
| Pivoting and cutting sport | About 4–6 months | Full training completed without swelling or giving-way; cleared at review | Longer for root repairs: your reviews set the date |
| Kneeling and deep squatting | From 3–4 months, as cleared | Restrictions formally lifted at review | Reintroduce gradually: padded surface, short exposures first |
You will often hear "no flying for six weeks" after joint replacement. Be aware that this is a convention, not a proven rule: a 2025 review found limited data and no demonstrated difference in clot risk between people who did and did not fly after hip or knee replacement: mostly within the first week.
The six-week convention reflects practical realities rather than trial evidence: managing airports and cramped seating, being past the highest-risk clot window while still on prevention, the higher baseline clot risk of long-haul flights over four hours, and individual airline and travel-insurance rules, check both, as some airlines impose their own restrictions.
If you need to travel long-haul in the first six weeks, talk to the rooms first so clot prevention, an aisle seat, stockings and on-board movement can be planned.
None of these should be watched overnight to see how they go. Early treatment of a problem is simple; late treatment is not.

CALL THE ROOMSCall the rooms: same day
For joint replacement patients, a wound problem is never something to "wait and see". Early treatment of an infected joint replacement is vastly more successful than late treatment, call the rooms the same day.
It matters enormously. Two very different recoveries come out of the same keyhole operation. Your operation record says whether the torn piece was TRIMMED (partial meniscectomy: the other guide, with a days-to-weeks timeline and no brace) or STITCHED (meniscal repair. This guide, with a brace, crutches and a months-long timeline). The decision is often made during surgery, so many patients do not know which was done until they wake up. If you are not sure which you had, call the rooms before following any timeline here.
Because bending is exactly what shears the stitches. Only the outer quarter or so of the meniscus has a blood supply, so a repaired meniscus heals slowly. Three months and more, and deep bending and twisting in that window can pull the healing tear apart. The brace caps the bend at 90 degrees for the first 4–6 weeks so the repair is never taken into its danger zone. Protecting it now buys you a meniscus for life; a failed repair means another operation and a higher long-term risk of arthritis.
Driving is deferred while you are in a range-limiting brace. A brace that caps your knee movement is incompatible with working the pedals safely, and with meeting the emergency-stop standard. Once the brace comes off at 4–6 weeks, the usual criteria apply: off strong pain relief, able to perform an emergency stop at full force without hesitation, practised in a stationary car first. We discuss your specific timing at the review where the brace is weaned.
Between 2 and 6 weeks, with the amount of weight set by your repair type. Your discharge letter has your exact prescription. Root and radial repairs commonly mean touch weight bearing (foot resting on the ground for balance only) for 4–6 weeks, because those repairs are most vulnerable to load. Weight bearing is progressed at your reviews, not by how the knee feels.
From about 3–4 months, on a quiet knee. One that does not swell in response to training, with the strength gates met and clearance at your review. Running restarts as straight-line work in stages; change-of-direction drills come later. If the knee swells after a run, that is a vote against the next progression, not a reason to push through.
Typically about 4–6 months, and longer for root repairs. Pivoting and twisting under load is the exact mechanism that re-tears repairs, which is why it is the last thing restored: no pivoting or twisting at all for the first 3–4 months, then a graduated build through drills and full training before competition. Your reviews set the actual clearance date.
Because your tear was worth saving. The meniscus is the knee’s shock absorber, and losing part of it raises the long-term risk of arthritis in that compartment. When a tear sits where it can heal and has a repairable pattern, stitching it preserves the meniscus for life: a slower recovery now in exchange for a better knee for decades. Trimming is the right operation when the tear cannot heal; repair is the right operation when it can.
Follow the instructions given at your brace fitting, practice varies with the repair, and your discharge letter is the authority. What never varies: do not change the range dial yourself, keep the straps snug but not tight, and call the rooms about rubbing or pressure areas rather than padding the brace yourself.
Desk work is often possible early, on crutches, once you are off strong pain relief and have transport sorted, since you cannot drive in the brace. Physical work is individually planned, because the no-kneeling, no-squatting, no-twisting restrictions run for 3–4 months and most manual jobs collide with at least one of them. Raise your job demands at the first review so modified duties can be arranged early.
No, and this is the most important question in the guide. A repaired meniscus routinely feels good long before it is healed, because the stitches hold everything still and comfortable. Healing takes three months and more; comfort at week three tells you nothing about the strength of the repair. The stitches, not the pain, set the pace: the brace and crutches come off when your review says so.
A failed repair usually declares itself with new catching, locking, or pain and swelling in the joint line, sometimes after a specific twist, sometimes gradually. It generally means another operation, most often trimming the failed portion, and it carries a higher long-term risk of arthritis, which is exactly why the restrictions in this guide are worth taking seriously. If you get new mechanical symptoms at any stage, call the rooms.
Then this guide does not apply to you. Cartilage repair procedures follow a completely different pathway, typically 6–8 weeks of protected weight bearing and 9–12 months before impact sport. Call the rooms for your specific protocol rather than following any timeline here.
