Knee brace for dogs: what a study on cranial cruciate ligament rupture measures
Published by Planète Pets · managing editor: Clément Lacaille · how our guides are written
Does every cranial cruciate ligament rupture in a dog need surgery, or can a knee brace avoid the scalpel? A recent Slovenian study offers concrete numbers on this conservative alternative, still little known among owners. The rest of our accessory picks are gathered in the dog accessories section.

Two dogs, 32 days of follow-up
Aljaž Muršec, Monika Pavlović, Tomaž Lampe and Vladimira Erjavec published, in 2025 in the journal Animals, a case study of dogs fitted with a custom-made knee orthosis after a recent cranial cruciate ligament rupture (see the study). The two dogs followed wore the brace gradually, a few hours a day at first, then all day during periods of activity after two weeks. A weight-distribution platform tracked how load shifted between limbs at several points over the period.
A weight shift that reverses
Before treatment, both dogs shifted most of their weight onto their front legs to spare the injured hind limb: 70% forward for the first dog, 60% for the second. After 32 days in the brace, that share dropped to 62% and 55% respectively, and the load carried by the injured limb itself increased by 0.97 kg and 2.23 kg depending on the dog. One of the two even reached near-symmetrical weight bearing between its two hind legs by the end of the study.
What this study does not show
Two dogs allow no statistical generalisation: this is a case study, not a controlled trial comparing bracing to surgery across a large sample. It also says nothing about the joint's long-term outcome or the risk of arthritis compared with surgical stabilisation such as TPLO. A literature review on the topic puts owner satisfaction at 86% with a brace versus 98% after surgery, a gap that should be read alongside this methodological caveat.
What it changes day to day
- Never improvise a brace without veterinary advice: a poorly fitted one can worsen instability rather than offset it, unlike the custom-fitted orthosis tested in this study.
- Plan a gradual adjustment period, following the two-week pattern seen here, rather than imposing full-time wear from day one.
- Pair it with suitable bedding during recovery: our guide to the orthopedic dog bed covers the criteria that matter for a limb in rehabilitation.
- Discuss both options with the vet rather than ruling out surgery outright: bracing is mainly documented for dogs where surgery is contraindicated or unaffordable.
Frequently asked questions
Does a brace replace cruciate ligament surgery?
Not necessarily for every dog: this study covers only two cases, and the literature reports somewhat lower owner satisfaction than after surgery. It is an option to discuss case by case with an orthopaedic vet.
How long does the brace need to be worn?
In this study, wear was introduced gradually over two weeks then kept on all day during activity; total treatment length varies with each dog's clinical progress.
Does a brace suit every dog?
That is not what this two-dog case study shows: the decision depends on weight, age, degree of instability and budget, to be assessed with the vet. Find all our guides on the dog hub.
