From Surgery to Strength: A TPLO Rehabilitation Success Story

When a 5-year-old medium-to-large breed dog underwent TPLO surgery on his right hind limb, the surgical procedure was only the first step in his recovery.

While the operation successfully stabilised the stifle (knee) joint, true functional recovery required something more: structured, progressive rehabilitation.

This case highlights why physiotherapy after TPLO surgery is not optional - it is essential.

What Happens After TPLO Surgery?

TPLO (Tibial Plateau Levelling Osteotomy) is performed to stabilise the knee following a cranial cruciate ligament rupture. The surgery changes the biomechanics of the joint, allowing the dog to bear weight without the ligament.

However, surgery alone does not:

• Restore lost muscle mass

• Correct compensation patterns

• Rebuild neuromuscular control

• Prevent secondary strain in the back and forelimbs

• Eliminate stiffness

Without guided rehabilitation, many dogs continue to show subtle lameness, weakness, or long-term compensation.

Early Post-Operative Stage

At four weeks post-surgery, this patient presented with:

• Mild to moderate lameness on the surgical limb

• Inflammation around the stifle

• Noticeable muscle atrophy in the operated hind limb

• Compensatory tightness through the back and forequarters

• Mild discomfort at end-range flexion and extension

This presentation is extremely common after TPLO surgery.

The Initial Focus Was:

• Controlling inflammation

• Supporting tissue healing

• Maintaining safe joint range of motion

• Preventing excessive compensatory strain

• Introducing gentle muscle activation

Treatment included:

• Laser therapy

• Manual therapy

• High-intensity PEMF

• Controlled range-of-motion work

• Strict activity modification

The Strength-Building Phase

By approximately eight weeks post-surgery, improvement was evident.

Lameness had reduced significantly. Joint heat had resolved. The surgical limb was more comfortable during movement.

However, muscle measurements showed clear asymmetry between hind limbs - a strong reminder that muscle rebuilding takes time and guided progression.

At this stage, rehabilitation progressed to include:

• Underwater treadmill therapy

• Controlled sit-to-stand strengthening

• Weight-shifting exercises

• Balance work on unstable surfaces

• Progressive pole work

• Ongoing manual therapy for compensatory areas

The aim shifted from healing to rebuilding strength, coordination, and joint stability.

The Long-Term Outcome

Three months later, the patient returned to normal daily activities and was confidently off-leash again.

On reassessment:

• No marked lameness was observed

• Muscle mass had significantly improved

• The surgical limb was comfortable

• Only mild residual compensatory tightness remained

Importantly, subtle secondary strain was identified in the lumbar spine and forequarters - areas that often work harder during the early recovery phase. These were addressed proactively to prevent future problems.

This highlights an important message:

Just because a dog appears “normal” does not mean their biomechanics are fully restored.

Why Post-TPLO Physiotherapy Matters

Rehabilitation after TPLO surgery helps to:

✔ Restore muscle symmetry
✔ Improve joint range of motion
✔ Reduce compensatory back and forelimb pain
✔ Protect the opposite hind limb
✔ Improve long-term joint health
✔ Lower the risk of early osteoarthritis progression

Many cruciate injuries occur in the opposite limb within 1–2 years. Proper strengthening and symmetry restoration can help reduce this risk.

Rehabilitation Is an Investment in the Future

Surgery stabilises the joint.

Physiotherapy restores function.

When rehabilitation is structured, progressive, and tailored to the individual dog, outcomes are significantly improved - not just in the short term, but for long-term joint health and quality of life.

Final Take-Home Message for Pet Owners

If your dog has undergone TPLO surgery, ask yourself:

• Has muscle mass been measured and monitored?

• Has compensation through the back or forelimbs been assessed?

• Is strengthening progressing safely and appropriately?

• Has your dog been cleared for off-leash activity based on objective reassessment?

If the answer is no, physiotherapy could make a significant difference.

Every successful surgical outcome deserves an equally successful rehabilitation journey.
