TPLO recovery in dogs: a week-by-week guide after cruciate ligament surgery

TPLO recovery happens in stages: one to two weeks for the wound to heal, about eight weeks of very controlled rest while the bone knits together, then two to four months of gradual return to activity. Most dogs are walking without a limp again by around 10 weeks and are back to full activity at around 6 months. Your role during this time is essential: here is the week-by-week timeline, the rehabilitation exercises and the signs that should ring alarm bells.

TPLO in a nutshell: why recovery is so tightly controlled

TPLO (tibial plateau levelling osteotomy) is the most widely used technique for surgery on a cruciate ligament rupture in dogs of medium to large size. The surgeon doesn’t replace the ligament: they cut the top of the shin bone (tibia) in a curve, rotate it so that the tibial plateau is almost level, then fix it in place with a plate and screws. The knee becomes stable without the ligament, because the thigh bone no longer ‘slides’ forwards each time the dog puts weight on the leg.

This stability depends on one condition: that the cut bone heals properly. Until it has healed, the plate takes all the strain. A jump off the sofa, a sudden dash after a cat or a slip on a tiled floor can be enough to shift a screw, crack the bone or damage the meniscus. That is why the rest instructions seem so strict, even though your dog often feels better very quickly.

According to the ACVS (American College of Veterinary Surgeons), 85 to 90% of dogs that have surgery show a clear improvement, and most return to an active life. A review of 72 studies published in 2022 also notes that TPLO comes with a lower rate of surgical site infection than TTA, the other main technique (Wemmers et al., 2022).

TPLO recovery: the week-by-week timeline

This timeline is a guide only. It is based on the stages described by the ACVS and VCA Animal Hospitals and on common rehabilitation protocols. Your surgeon’s instructions always come first, as they take into account your dog, their weight, the state of the meniscus and how the operation went.

The first 3 days: managing pain and rest

Your dog will usually come home the same day as the operation or the day after. They may be drowsy, a little nauseous from the anaesthetic, and may whine or pant the first night. Give the prescribed medicines exactly as directed (painkillers, veterinary anti-inflammatories, sometimes antibiotics), right to the end of the course, even if your dog seems fine. If your vet has advised it, apply a cold pack wrapped in a cloth to the knee, never putting ice directly on the skin.

Weeks 1 and 2: the wound comes first

The priority is for the wound to heal without infection. Check it twice a day: slight redness and a small bruise are common, but discharge, a smell or swelling that is getting bigger are not. The cone (or a post-operative recovery suit) stays on until the stitches are out: a single bout of determined licking can be enough to open up or infect the wound.

Weeks 3 to 8: the hardest phase for owners

This is often the riskiest period. Your dog is bearing weight well, is in less pain and wants to play… while the bone has not yet healed. Hold firm: the lead stays on for every outing, including in the garden. Progress is measured by how evenly your dog puts weight on the leg and how the thigh muscle is building back up, not by how keen your dog is to run.

After the check-up X-ray: a gradual return

If the X-ray shows good healing, the programme expands. The rule is simple: one new thing at a time, and watch your dog the next day. If your dog is limping more or seems stiff, go back to the previous stage for a few days.

Rehabilitation after TPLO: what the research says

A systematic review of 19 studies on rehabilitation after cruciate ligament surgery concludes that it improves recovery (Alvarez et al., 2022). Therapeutic exercise is the most studied, and cold compression has three studies in its favour, two of them of good methodological quality. In an older trial of 8 dogs that had TPLO, those on a physiotherapy programme three times a week had, at 6 weeks, better thigh muscle and a more mobile knee than those who only went on walks at home (Monk et al., 2006).

In practice, a programme supervised by a vet with rehabilitation training or a veterinary physiotherapist, possibly including hydrotherapy once the bone has healed, is a real plus. Our guide to dog physiotherapy and hydrotherapy explains what the sessions involve.

Three exercises to do at home

Only start when your vet says you can, and stop if your dog is in pain, lifts the leg or tenses up.

Exercise

Gentle knee bends

Level

Easy

Duration

3–5 min

Frequency

2–3 times a day

Focus

Range of movement in the operated knee

1. Lay your dog on its side, operated leg uppermost, on a comfortable bed.
2. Hold the thigh with one hand and the lower leg just above the ankle (hock) with the other.
3. Slowly bend the knee until you feel slight resistance, then straighten it in the same way.
4. Repeat 10 to 15 times, always slowly, keeping an eye on your dog’s expression and ears.

Good to know: only do this exercise in the first few days if your vet has shown you how. It should never make your dog whimper.

Exercise

Slow walking with stops

Level

Easy

Duration

5–15 min

Frequency

Every outing

Focus

Even weight-bearing on the operated leg

1. Shorten the lead so your dog walks beside you, at a walk.
2. Walk very slowly: a dog walking fast can ‘cheat’ by shifting weight onto the other legs.
3. Every 20 to 30 seconds, stop and have your dog stand still for a few seconds, all four paws on the ground.
4. Set off gently again and lengthen the outing according to the timeline above.

Good to know: a dog that puts the leg down firmly when standing still is an excellent sign of progress.

Exercise

Ground poles

Level

Intermediate

Duration

5 min

Frequency

3–4 times a week

Focus

Knee flexion and coordination

1. Lay 4 to 6 broom handles on the ground, spaced roughly your dog’s height at the withers apart.
2. Walk your dog over the poles on the lead.
3. Do 3 to 5 passes in each direction.
4. When this is easy, raise the poles by just a few centimetres.

Good to know: keep this for after the check-up X-ray, at around 8 weeks. Your dog should step over the poles, never jump.

You will find more progressive routines in our exercises for dogs with arthritis, all of which can be done at home.

Organising your dog’s recovery after cruciate surgery

Recovery should be planned before the operation. A few simple changes make the eight weeks of rest much easier.

• A limited rest area: a dog pen, a small room or a large crate, with a thick, firm bed. Your dog should not be able to run about when you are not there.
• Floors that don’t slip: non-slip rugs or runners of yoga mats along the usual routes.
• No sofa, no bed, no stairs: stair gates, a ramp for the car, and carrying for a small dog.
• A support harness or a towel passed under the belly to help your dog get up and walk in the first few days.
• Things to do without moving about: snuffle mats, stuffed toys, approved chews, short calm training exercises. A bored dog is harder to keep quiet.
• An adjusted food allowance: activity drops sharply for two months. Ask your vet how to adjust the ration to avoid weight gain, which would put extra load on the operated knee.

These changes will also come in handy later on: our article on home adaptations for a senior dog has more practical ideas for older dogs and dogs with arthritis.

Dog limping after TPLO: when to worry

A limp that gets better week by week is normal. What should worry you is a sudden change or progress that is heading in the wrong direction. According to VCA Animal Hospitals, complications affect on average 10 to 30% of dogs depending on the study, often in a mild form, and infection is the most common.

If the limp lasts beyond 3 months or affects the other leg, our article on a dog limping on a back leg will help you take stock before your appointment.

After recovery: protecting the operated knee… and the other one

A successful TPLO stabilises the knee, but it doesn’t undo wear that is already there: arthritis in the knee can progress over the years, though more slowly than in a knee left unstable. Above all, according to the ACVS, 40 to 60% of dogs affected on one side will at some point develop the same problem in the other knee, often within 12 to 18 months of the diagnosis.

1. Keep your dog slim: you should be able to feel the ribs easily. Being overweight is a recognised risk factor for cruciate ligament disease. Our guide to overweight dogs and joint health explains how.
2. Favour regularity: moderate daily activity is better than big efforts at weekends.
3. Warm your dog up: 5 to 10 minutes of walking before running or playing.
4. Limit repeated ball throwing and sharp turns on slippery ground.
5. Keep an eye on the other leg: sitting lopsided, stiffness on getting up or an intermittent limp are reasons to see your vet promptly.

Key points on TPLO recovery

TPLO gives excellent results, provided you respect the pace at which bone heals: eight weeks of patience on a short lead, regular rehabilitation, then a gradual return to activity up to 4 to 6 months. Note your dog’s progress every week, film your dog walking for the check-ups and don’t hesitate to call your vet if you have any doubts. For more, see all our advice on dog joint health.
