Which knee brace should I wear after ACL surgery, and for how long?

The early post-operative brace

A hinged brace has adjustable stops that limit how far the knee bends or straightens. After ACL surgery it may be used when:

• A meniscus repair needs protection from deep bending under load
• The MCL, posterolateral corner or another ligament was also treated
• Cartilage surgery was done at the same time
• Your surgeon wants the knee locked straight while you walk in the first days

When the ACL alone was reconstructed, studies have not shown that routine bracing improves the final result, and many surgeons do not use one.

The functional brace for sport

Some players use a custom or off-the-shelf functional brace when returning to football, padel or basketball. It may help confidence, but evidence that it prevents re-injury is limited. It is never a substitute for strength, hop testing and a proper return-to-sport programme.

Wearing a brace well

Line up the hinge with the side of the knee joint, keep straps snug but not cutting in, and check the skin daily. In the heat, a thin cotton layer underneath reduces sweating and rubbing. Do not change the hinge settings yourself; follow the plan from your surgeon or physiotherapist.

When to get help

Remove the brace and seek advice if your foot becomes numb, cold or discoloured, or if the calf swells or hurts, which can signal a blood clot. At Aman Hospital, Dr. Gelber explains at discharge whether you need a brace, the settings and when to stop.
