Stairs After TPLO: None for Two Weeks, Sling-Assisted Through Week 8

The typical TPLO protocol treats stairs in three phases: none at all for weeks 0–2, only-when-unavoidable — leashed and sling-assisted, one slow flight — for weeks 2–8, and a gradual return after the 8-week recheck radiographs. Your surgeon's discharge sheet overrides everything below, and that is not a formality: no published evidence-based rehabilitation guideline exists for anyone to follow, so protocols genuinely differ between practices.^[1] This article exists to explain the why and the how.

The stairs rules, week by week#

Why are stairs the specific thing surgeons warn about?#

TPLO — tibial-plateau-leveling osteotomy — stabilizes a knee with a torn cranial cruciate ligament by cutting the top of the tibia, rotating it, and plating it in place.^[2] Until that cut knits, the plate and screws are carrying load the bone can't. Flat, slow leash walking is well within what the hardware tolerates.

Stairs are different, and the difference has actually been measured rather than assumed. Two kinematic studies from the same University of Tennessee group put healthy dogs on custom staircases and filmed the hind limbs:

• Climbing asks the knee for more motion than trotting does. In eight orthopedically normal dogs ascending four steps, every joint of the pelvic limb went through greater total excursion than during a flat trot, and maximum flexion of the stifle and the hock was significantly greater. The stifle also extended less on the stairs — the joint works through a tighter, deeper arc.^[3]
• Descending asks for more still, and more than a ramp of the same angle. In seven dogs walking down stairs versus a continuous decline of equivalent slope, stair descent produced significantly greater stifle and hock flexion, and significantly greater range of motion at the hip, stifle and hock. The authors' own clinical note is the one worth carrying to the hardware store: ramp descent "may be easier for dogs with limited motion of pelvic limb joints."^[4]
• And a slip on a staircase is not a stumble. Sixty-one dogs presented to two university emergency hospitals after falling down stairs. Lameness was documented in 28%, lameness with ligament or tendon disruption or a joint luxation in 7%, and a frank fracture in 13%. Spinal cord injury of some grade appeared in about a third, and traumatic brain injury in 8%. Seventy-four per cent went home.^[5]

Read that last one carefully, because it cuts both ways. Most dogs who fall down stairs are fine. But one in eight of the dogs who arrived at an emergency room had broken something — and those were ordinary dogs with intact tibias, not dogs eight weeks into carrying a plate across a saw cut.

What we cut here. This page used to say the risk peaks at weeks 3–5, when "the bone is mid-remodeling and at its mechanically weakest." We could not source that claim and have removed it, as we removed it from the TPLO recovery guide on the same day. What is documented is which dogs get into trouble at all: across 1,519 TPLO procedures in 1,231 dogs, the total complication rate was 11.4% — 3.1% major, 8.3% minor — and complications were more likely in German Shepherd Dogs (odds ratio 3.2), in dogs with a tibial plateau angle over 30° (1.6), and with every 4.5 kg of extra body weight (1.10).^[6]

Those three risk factors are all things you already know about your dog before surgery day. If yours is a heavy German Shepherd with a steep plateau angle, this is the paragraph to take personally, and the gates go up higher.

Why is down riskier than up?#

Going up, the dog works against gravity: movement is slower, each push is deliberate, and a stumble usually ends on the next tread. Going down, gravity does the accelerating, and the braking lands on the front end — which is already the loaded end. Weighed on a digital scale while standing, 552 dogs across 123 breeds carried a mean of 60.4% of their mass on the forelegs.^[7] Meanwhile the hind limbs flex deeper than they would on any slope to control the descent.^[4]

And the emergency series is the tell. It is a series of dogs who fell down the stairs — that is the direction that reaches a hospital.^[5] Nobody has counted how many dogs fall going up and simply get up again, so this is not proof that ascent is safe. It is a reason to spend your care budget on the descent.

Practical consequences: if a flight is unavoidable twice a day, descend with maximum control — sling snug before the first tread, leash short, your pace not the dog's. If you can arrange life so the dog only ever goes up (sleeping upstairs with you, carried or rerouted down), you have removed the worse half of the problem. Better still is removing both, which is the next section.

How do I manage stairs with a large or XL dog I can't carry?#

Small-dog owners carry their way through weeks 0–2. With an 80-pound Shepherd or a 110-pound Rottweiler, that's not an option — and picking up a big dog badly is dangerous for both of you. The plan for big dogs is to engineer stairs out of the recovery, then equip the exceptions.

First, the ground-floor conversion. For eight weeks, the dog lives where the yard door is: a firm bed or pen on the ground floor (our picks are in the best dog beds for post-surgery recovery), feeding station nearby, baby gates at the top and bottom of every staircase. Gates at both ends matter — one gate means one open end, and an unsupervised attempt at 6 a.m. Most owners sleep on the couch or an air mattress near the dog for the first two weeks. That's normal; plan for it.

Second, the assist gear for unavoidable flights.

The GingerLead is the fast tool: a padded single-piece sling with an integrated leash you can have under the belly in seconds. For stairs, it lets you take meaningful weight off the rear end while the dog keeps all four feet working. It's rear-support only, which is exactly what a TPLO dog needs — and exactly why it is the wrong tool if your dog is also weak in front. Two things the listing photograph does not tell you: the chest harness the maker's own copy recommends clipping the leash to is not included, and the clean return window is ten days, with a restocking fee after that. Size it with the manufacturer's free towel test before you spend anything.

For dogs over roughly 70 pounds, for bilateral cases, or for any recovery with daily unavoidable stairs, the Help 'Em Up is the better instrument. It stays on the dog all day, so there's no wrestling gear on at the top of a staircase, and the purpose-built hip handle gives you real leverage with your back straight. We used to write that it is "what rehab practices reach for with big dogs." We have no survey behind that sentence and it is gone; the defensible version is the design argument, which is strong enough on its own. Sizing is critical — measure twice before ordering, and note the buy box on Amazon is currently held by a third-party reseller rather than the brand, at a real premium over the manufacturer's own direct price. More options in our dog lift harness guide.

Sling technique, up versus down. Going up: you walk beside and slightly behind, sling or hip handle taking steady upward tension — supporting, not lifting the rear off the ground — one tread at a time, with a helper ahead of the dog if you have one. Going down: you move to beside-and-slightly-ahead so you can slow the front end with the leash while the sling controls the rear, and you set the pace tread by tread. In both directions, the leash is short and the dog never gets the option to bound.

Third, bypass what you can.

Two to four porch or deck steps are a ramp problem, not a stairs problem — and the substitution has a measured basis rather than a marketing one. Walking down a ramp asks significantly less range of motion from the hip, stifle and hock than walking down stairs of the same slope, which is precisely why the authors of that study suggested ramps for dogs with limited joint motion.^[4] The Pet Gear Tri-Fold is 71 inches long and 19.5 inches wide — that extra width is the difference between a stiff dog placing four feet confidently and refusing — with a carpet tread a nail-scraping dog will walk without you covering it in a towel.

Two corrections to what this page used to say about it. It does not weigh under 11 pounds; that figure belongs to a different, much narrower ramp in the same range. Amazon's own figures for the 71-inch siblings are around 25 pounds, so treat this as a two-hand carry you leave in place rather than a thing you tote around. And the warranty is 30 days, not the year we printed for months — Pet Gear's own listing field says so on every 71-inch variant we checked.^[8] The 200-pound rating is real and is a ceiling worth respecting if you plan to walk up alongside your dog. For a full indoor staircase, a ramp is not the answer — but for the three steps between the back door and the yard it removes dozens of loaded descents a week. Longer options are in our ramp guide.

Hardwood treads and the slick landing at the bottom of a staircase are where assisted descents go wrong. ToeGrips slip onto the toenails and restore grip on wood, tile, and laminate; nothing touches the paw pad, which is why dogs accept them where they refuse boots. Two honest limits: they are a recurring cost rather than a one-off, since the maker says a bag lasts one to two months, and Amazon stocks only four of the seven sizes. Pair them with stick-on tread strips or a runner on the staircase itself — the runner is the cheaper half and does more. If your whole house is slick flooring, start with dog slipping on floors; traction is the cheapest insurance in the entire recovery.

What if something goes wrong on the stairs?#

One uneventful accidental flight, with a dog that trots away moving exactly as it did before, is usually a scare rather than a setback — watch closely for 24–48 hours and tighten the gates. The pattern to never repeat is daily "small" exceptions: the two steps to the den, every day, unassisted, is how a protocol quietly falls apart.

While you are watching the operated leg, watch the other one too. In 831 medium-to-large dogs who were eight or older at their first cruciate rupture, 19.1% ruptured the other side, at a median of 12.9 months.^[9] Stairs taken badly on a good leg are load the good leg did not need. That is one in five dogs, not a coin flip — but it is reason enough that the gates protect both knees, not one.

The bottom line#

Stairs are the highest-load, highest-consequence movement in a TPLO recovery, and the rules are simple even when compliance isn't: none for two weeks, assisted-and-unavoidable-only until the 8-week films, gradual after that — with down always treated as the more dangerous direction. Gate the stairs, move life to the ground floor, and equip the exceptions with a sling or hip-handle harness, a ramp for short step runs, and traction on every hard surface.

And hold the eight-week mark loosely. It is when most practices re-radiograph the cut, not when the dog is finished: in force-plate studies, dogs after TPLO reached limb loading indistinguishable from dogs who had never been injured somewhere between six months and one year after surgery.^[10] Cruciate rupture is one of the most common causes of hind-limb lameness in dogs, and it is thoroughly documented if you want the deeper background.^[2] For everything beyond stairs — cones, beds, week-by-week walking — start with the TPLO recovery gear checklist and the full TPLO recovery guide.

The hardest part is not the fortnight when he is sore and you are frightened and everyone is careful. It is the week he looks fine at the bottom of the staircase and you are tired, and the films have not been taken yet. He cannot tell you the difference between feeling better and being healed. The gate can.

Sources#

Every source below was opened and read on 14 August 2026. One claim that previously appeared on this page — that the bone is at its "mechanically weakest" during weeks 3–5 — was removed because no source could be found for it, and one product figure, the ramp's weight, was corrected against the manufacturer's own listing. Both removals are stated in the text above rather than made silently.

The two kinematic studies above were done in healthy dogs, not dogs recovering from a tibial osteotomy. Nobody has measured what a staircase does to a plated tibia at week four, and it would be difficult to do so ethically. Treat the joint-motion figures as the reason for the restriction, not as a measurement of your dog's risk.
