Choosing the Right Knee Brace: A Physiotherapist's Perspective
Not all knee braces are created equal — and selecting the wrong type can delay your recovery or, in some cases, create a false sense of security that leads to re-injury. As a physiotherapist, I see patients arriving with braces that are either far too aggressive for their stage of recovery, or completely insufficient for the demands of their activity.
This guide covers the main brace categories and the situations in which each is clinically appropriate.
Types of Knee Braces Explained
1. Prophylactic Braces
Designed to prevent injury in high-risk contact sports. Not typically indicated for rehabilitation — these are primarily used by athletes with a history of ligament injury.
2. Functional Braces
Used to support a previously injured knee and allow a safe return to activity. The DonJoy Bionic falls into this category. Functional braces are typically used from weeks 6–12 post-ACL reconstruction through the return-to-sport phase.
3. Rehabilitative Braces (Hinged)
Hinged braces are used in the early post-operative period to limit range of motion to a surgeon-prescribed safe zone. They protect the surgical repair while allowing controlled, progressive movement. Critical in the first 4–8 weeks after ACL surgery or total knee replacement.
4. Unloader Braces
Designed to shift load away from a damaged compartment of the knee. Specifically indicated for osteoarthritis affecting primarily the medial or lateral compartment.
5. Compression Sleeves
Provide proprioceptive feedback, warmth, and mild swelling management. Appropriate for chronic knee pain, mild instability, and return to light activity. Not suitable as the sole support following ligament surgery.
When a Brace Is NOT Enough
A brace supports your knee — it does not rebuild the muscle and movement control that protects it. Research consistently shows that quadriceps and hip strength are the primary determinants of knee stability following injury. Your brace should be part of a structured rehabilitation programme, not a substitute for one.
Fit Is Everything
A poorly fitted brace migrates, causes skin irritation, and provides inconsistent support. Always measure your thigh and calf circumference at the points specified by the manufacturer before selecting a size. When in doubt, consult your physiotherapist for a fitting.
