TPLO Surgery Complications: Warning Signs and When to Call Your Surgeon

Most changes during early TPLO recovery are not emergencies, but some warrant guidance from the surgical team. Knowing what the incision, appetite, mobility, and comfort should generally look like can help owners respond without panic or delay.

Tibial plateau leveling osteotomy (TPLO) is a major orthopedic procedure that uses a bone plate and screws while the tibial osteotomy heals. Complications are possible even with careful planning and aftercare. This guide explains common concerns in calm, practical terms. Your dog’s discharge instructions and treating surgeon are the best sources for patient-specific advice.

What Can Be Normal Early in Recovery?

Ask the discharge team what is expected for your dog, but early changes may include:

  • Sleepiness or mild disorientation after anesthesia
  • Reduced appetite for a short period
  • Mild bruising or swelling near the incision
  • Variable early use of the operated leg
  • Stiffness after rest
  • A small amount of clear or blood-tinged fluid immediately after surgery

These changes should generally remain mild and improve. A trend toward greater pain, swelling, discharge, weakness, or loss of function deserves a call.

Incision Problems

Check the incision daily in good light. The edges should stay together, and the area should become less reactive over time. Prevent licking and chewing with the protective device prescribed at discharge.

Contact the Team If You See

  • Separation or opening of the incision edges
  • Increasing redness, heat, swelling, or tenderness
  • Persistent bleeding
  • Thick, cloudy, green, yellow, or foul-smelling discharge
  • A growing lump or fluid pocket
  • Damaged sutures or staples
  • Repeated licking or chewing despite protection

Do not apply peroxide, alcohol, ointment, spray, bandage, or another topical treatment unless the veterinary team directs you to do so.

Surgical-Site Infection

Infection can involve the skin, deeper tissues, bone, or implants. Signs can include worsening redness, warmth, swelling, discharge, pain, fever, low appetite, lethargy, or a limp that worsens instead of improving. Some implant-associated infections appear later rather than during the first days.

Prompt evaluation allows the team to examine the incision, review radiographs or laboratory findings if needed, and decide whether wound care, medication, culture, or another treatment is appropriate. Do not start leftover antibiotics, because an incorrect drug or incomplete course can complicate evaluation.

Implant Concerns

The plate and screws hold the rotated tibial segment while bone heals. Irritation, loosening, breakage, or loss of fixation are possible. Risk can increase if the dog runs, jumps, falls, slips, or plays before healing is confirmed.

Possible warning signs include sudden loss of leg use, new swelling, a marked increase in pain, an unusual limb position, or a new decline after a period of improvement. Contact the surgeon after any significant recovery accident even if the dog initially seems comfortable.

Fracture

A fracture near the osteotomy or implant is an uncommon but important complication. It may occur during surgery or after excessive force is placed on the healing limb. Sudden severe lameness, swelling, pain, or deformity warrants prompt assessment.

Limit movement and follow the team’s transportation instructions. Do not attempt to straighten or splint the leg at home unless a veterinary professional specifically directs you.

Delayed Bone Healing

Bone healing varies with age, overall health, bone quality, activity control, and other factors. A dog can feel better before radiographs show adequate healing. That is why scheduled rechecks and follow-up images matter.

Delayed healing may not cause obvious symptoms. The surgeon may identify it on radiographs and extend restrictions, modify rehabilitation, or recommend additional evaluation. A longer recovery plan does not automatically mean the procedure has failed.

Meniscal Injury

The menisci are cartilage structures inside the knee that help absorb shock and distribute load. A meniscus can be injured with the original CCL tear or develop a later problem. A new click, sudden setback, persistent pain, or renewed lameness may raise concern for meniscal damage, although those signs are not specific.

The surgical team may recommend an examination and imaging or further joint evaluation depending on the history and findings.

Persistent or Recurrent Lameness

Some stiffness and variable weight bearing can occur early. Persistent or recurring lameness can have many causes, including incomplete healing, muscle weakness, arthritis, meniscal damage, infection, implant irritation, another knee condition, hip or back pain, or an injury in the opposite leg.

Keep a simple record of when the limp appears, what activity preceded it, and whether swelling or pain is present. A short video of walking may be useful if the clinic asks for one, but it does not replace an examination.

Medication Concerns

Contact the team about repeated vomiting, significant diarrhea, black or bloody stool, refusal of food, severe sedation, agitation, weakness, facial swelling, hives, breathing changes, or another unexpected reaction. Ask what to do before giving the next dose.

Never give human pain relievers or another pet’s medication. Do not repeat a dose automatically if the dog vomits, and do not double a missed dose unless the veterinary team provides that instruction.

Setbacks Caused by Excessive Activity

Many preventable setbacks happen because a dog feels better before the bone is healed. Common incidents include jumping from furniture, running through a door, slipping on a smooth floor, climbing stairs, playing with another pet, or escaping off leash.

If an incident occurs:

  1. Stop activity and return the dog to the recovery area.
  2. Observe comfort, limb use, swelling, and the incision without manipulating the leg.
  3. Contact the surgical team and describe exactly what happened.
  4. Follow guidance about monitoring, activity, medication, or a recheck.

Do not wait for dramatic symptoms before reporting a significant event.

When to Seek Emergency Care

Go to emergency care for difficulty breathing, collapse, uncontrolled bleeding, severe distress, repeated seizures, a suspected severe medication reaction, or another life-threatening change. If the concern is urgent but stable, call the surgical team or nearest veterinary facility for direction.

How to Reduce Complication Risk

  • Follow discharge instructions exactly
  • Use the prescribed recovery area and leash control
  • Cover slippery floors and block stairs and furniture
  • Keep the incision protection device on as directed
  • Give only prescribed medications
  • Attend rechecks and follow-up radiographs
  • Advance activity only after veterinary clearance
  • Report concerns early rather than treating them at home
