Dog Knee (Stifle) Brace

OrthoPets stifle braces support dogs with cruciate ligament injuries (ACL/CCL tears), fractures, and other hind leg conditions. Our custom knee braces provide stability, pain relief, and a trusted alternative to surgery for dogs of all sizes.

Mobility in motion: Real patients, real results
Force Coupling
Advanced biomechanical principles are used to stabilize stifle joint injuries such as the CCL, one of the most common injuries to pets.
Polycentric Hinges
Not all hinges are appropriate for pets. Our specially designed polycentric hinges are designed to replicate the complex motion of your dog’s knee (stifle) joint, providing articulation and limiting shear forces.
Adjustable Mechanical Strapping
Adjustable mechanical strapping gives you improved control and support with less demand on your grip strength making adjusting to muscle mass changes effortless
Waterproof
Getting into the water is not only fun for your pet, it can be the most important thing ever! Our material selections have been specifically focused on allowing your pet to enjoy complete freedom of activities, like swimming

Is a stifle orthosis right for you and your dog?

Injury to the cranial cruciate ligament (CCL) — also known as the ACL — is the most common orthopedic injury in dogs.This partial or complete ligament tear causes knee (stifle) instability, pain, and arthritis.

Treatment options include:

  • Surgical stabilization such as TPLO, TTA, or lateral suture (“tight rope”) procedures
  • Custom orthosis (brace) as a non-surgical alternative

A stifle orthosis (dog knee brace) may be appropriate when surgery is not ideal due to:

  • Age or advanced arthritis
  • Pre-existing health conditions
  • Anesthesia risk
  • Financial constraints

OrthoPets’ custom stifle devices provide external stabilization to improve comfort, mobility, and quality of life.

Can a Stifle Orthosis Help with Luxating Patella?

Luxating patella (dislocating kneecap) is a developmental condition common in both large and small breed dogs.
Severity is graded from 1 (mild) to 4 (severe):

  • Grade 1–2: Patella slips out occasionally but returns to place
  • Grade 3–4: Patella remains dislocated and typically requires surgery

A stifle brace can help stabilize some Grade 1–2 luxating patellas by influencing tibial orientation and improving patellar tracking.
However, Grade 3–4 cases are surgical candidates, as the patella cannot be mechanically held in place with a brace.

What to Expect with an Orthosis

1. Daily Use
  • The device must be worn all day and removed at night.
  • It provides stability only while on the limb — similar to how crutches support a human leg.
  • Dogs should not walk or jump during the night without the device on.
2. Adjustments Are Normal
  • Each device is custom-made to your dog’s anatomy.
  • One complimentary adjustment is included after fitting.
  • Additional fine-tuning may be needed, especially in the first few months as your dog becomes more active.
3. Follow-Up Care
  • Regular follow-ups ensure long-term success.
  • Your veterinarian and OrthoPets VOP Specialist will guide you through use and rehab.
  • Annual or twice-yearly checkups are recommended.
  • If adjustments are required, the device can be shipped to OrthoPets (2–4 business day turnaround).
4. Surgery May Still Be Needed

If your dog has a torn meniscus, surgery (partial medial meniscectomy) may still be required.
This cartilage injury can occur at the time of ligament rupture or later due to joint instability.

5. Rehabilitation Is Essential
  • Dogs adapt quickly to their orthosis with proper rehab and training.
  • Skills to relearn include sitting, standing, walking on varied surfaces, and climbing stairs.
  • Work with a certified rehabilitation professional (CCRT or CCRP) for best outcomes.
6. Arthritis Management

All dogs with cruciate ligament injury will develop some degree of arthritis.
A proactive pain and mobility plan—including supplements, physical therapy, and weight management—can slow its progression and keep your pet comfortable for years.

7. Clinical Evidence and Experience

While there are no formal studies directly comparing orthoses to surgery, OrthoPets provides nearly 1,000 stifle braces each year.
Our empirical experience and collaboration with university researchers continue to advance the science of veterinary orthotics.

Tarsal Cuff Addition Considerations

A tarsal cuff is an additional support component added to the distal end of a stifle brace to:

  • Improve suspension and rotational control
  • Provide extra purchase or stability for certain anatomies

All OrthoPets stifle devices are initially fabricated with a tarsal cuff to ensure optimal fit and limb control.
It can be modified later as needed depending on your pet’s movement and comfort.


Device Refurbishment

When to Refurbish

Orthoses are built to last the lifetime of your pet but experience normal wear and tear.
A refurbishment is recommended every 12–24 months, depending on activity level.

What’s Included

A full refurbishment includes:

  • New foam liner
  • New straps and pads
  • Replaced tread (if applicable)
  • Polished hardware and finish

Your brace will look and function like new after refurbishment.
If only straps or hardware are needed, you can order replacements directly from OrthoPets or source compatible parts locally.

OrthoPets devices are custom fabricated based off of an impression of your patient’s/pet’s leg. We fabricate each orthotic brace or prosthetic device to support the therapeutic mobility goals.

Manufacturing & Order Fulfillment Timeline:

  • The fabrication time for an orthosis is 9 business days. The fabrication for a prosthesis is 15 business days. Business days are M-Th. OrthoPets provides custom devices and therefore, fabrication will not begin until full payment has been received.
