Signs of TPLO Failure or Complications in Dogs
Recovering from TPLO surgery can feel like an emotional rollercoaster. Some dogs improve steadily, while others have setbacks, swelling, limping, or changes that leave owners wondering whether recovery is really going to plan.
The difficult part is that some ups and downs are completely normal — while others may suggest a complication that needs attention.
At Balance Vet Rehab, we regularly help dogs from Brisbane, the Gold Coast, and Scenic Rim who are struggling after cruciate surgery, including dogs with delayed recovery, weakness, stiffness, compensation injuries, and persistent lameness.
What Is Considered a Normal TPLO Recovery?
TPLO recovery is rarely perfectly smooth.
Many dogs experience temporary limping, muscle soreness, swelling, stiffness after rest, or occasional “off days” during healing. Recovery also tends to happen in waves rather than in a perfectly straight line.
That means a temporary setback does not automatically mean the surgery has failed.
However, there are certain signs that may indicate:
-
delayed recovery
-
implant irritation
-
meniscal injury
-
infection
-
poor muscle recovery
-
ongoing instability
-
overuse injury
-
or, more rarely, surgical complications
Understanding the difference between “normal healing variation” and a true complication can help owners seek support early before small issues become larger problems.
Why Rehabilitation Matters After TPLO
A technically successful surgery does not always guarantee a smooth functional recovery.
Even after excellent surgery, many dogs still experience:
-
muscle loss
-
altered movement patterns
-
weakness
-
reduced confidence using the leg
-
compensation onto the opposite hindlimb
-
stiffness in the back or hips
This is where rehabilitation can play an important role.
Our rehabilitation approach focuses on:
-
restoring strength
-
improving gait quality
-
reducing compensation
-
improving confidence using the limb
-
supporting safe return to activity
-
identifying issues early if recovery is plateauing
Common Signs of TPLO Failure or Complications
Persistent or Worsening Limping
One of the most common reasons owners seek help is ongoing limping weeks or months after surgery.
While mild limping can still occur during healing, concern increases when:
-
limping worsens instead of improves
-
your dog suddenly becomes more lame
-
progress plateaus for weeks
-
your dog consistently avoids weight-bearing
-
or your dog regresses after previously doing well
Sometimes this is related to muscle weakness or overactivity. Other times it may indicate:
-
meniscal injury
-
implant irritation
-
infection
-
delayed bone healing
-
or persistent instability

provides more detailed guidance.
Significant Swelling
Some swelling around the surgical site is expected early after TPLO surgery.
However, swelling may be more concerning when it:
-
suddenly increases
-
becomes hot or painful
-
persists longer than expected
-
starts draining fluid
-
or is accompanied by lethargy or reduced appetite
Mild swelling and firm thickening around the incision can sometimes persist for quite a while during healing, especially after increased activity.

Swelling After TPLO Surgery — What’s Normal?
Clicking or Popping Sounds
Some owners notice clicking, popping, or unusual movement during recovery.
Possible causes may include:
-
scar tissue movement
-
tendon movement
-
meniscal injury
-
implant-related irritation
-
altered gait mechanics
Not every clicking sound is dangerous, but persistent or painful clicking deserves assessment.
Refusal to Use the Leg
Most dogs begin toe-touching or partial weight-bearing relatively early after surgery.
Dogs that:
-
refuse to use the leg at all
-
suddenly stop using the limb
-
cry out during movement
-
or appear significantly painful
should be reassessed promptly.
Severe pain or complete non-weight-bearing may occasionally indicate:
-
implant failure
-
fracture
-
infection
-
or another major complication
Muscle Loss That Doesn’t Improve
Muscle atrophy is extremely common after cruciate injury and surgery.
However, some dogs struggle to rebuild muscle effectively, especially if:
-
activity progression is too rapid
-
pain persists
-
gait abnormalities remain
-
or compensation patterns develop
Poor muscle recovery often contributes to ongoing limping and reduced function long after the bone itself has healed.
Rehabilitation focuses heavily on rebuilding strength safely and progressively.
Behavioural Changes
Dogs experiencing pain or discomfort after TPLO may show:
-
reluctance to jump
-
difficulty rising
-
slower walks
-
irritability
-
restlessness
-
or reduced enthusiasm for exercise
Sometimes owners notice these changes before obvious limping develops.
Why Some Dogs Develop Setbacks After TPLO
Not all complications are surgical failures.
In many cases, setbacks occur because:
-
activity increased too quickly
-
the opposite cruciate ligament becomes overloaded
-
underlying arthritis progresses
-
muscle weakness persists
-
dogs compensate poorly
-
or rehabilitation was limited
Large dogs, athletic dogs, older dogs, overweight dogs, and highly active dogs may all face different recovery challenges.

When Should You Seek Help?
You should consider veterinary reassessment if your dog has:
-
worsening lameness
-
severe swelling
-
discharge from the incision
-
sudden regression
-
persistent pain
-
prolonged weakness
-
reluctance to bear weight
-
or recovery that simply “doesn’t feel right”
Owners know their dogs well. If recovery feels abnormal, it is reasonable to investigate further.
Early intervention can often prevent smaller issues becoming chronic problems.

How Rehabilitation May Help Dogs Struggling After TPLO
Depending on the individual dog, rehabilitation may include:
-
gait assessment
-
muscle strengthening
-
underwater treadmill therapy
-
balance and coordination work
-
pain management strategies
-
controlled exercise progression
-
mobility support
-
home exercise programs
Some dogs simply need structured progression and confidence rebuilding. Others benefit from identifying subtle compensation patterns or secondary pain sources.
At Balance Vet Rehab, we commonly assess dogs recovering from TPLO surgery across Brisbane, Gold Coast, and Scenic Rim — including dogs whose recovery has stalled or become complicated.

Reassurance for Worried Owners
One difficult recovery day does not automatically mean the surgery has failed.
Many dogs experience temporary setbacks during healing and still go on to recover very well.
At the same time, persistent pain, worsening lameness, or abnormal recovery should not simply be ignored or dismissed.
Careful assessment, appropriate rehabilitation, and gradual progression can often make a significant difference to long-term comfort and function.
