What is the difference between a knee brace and a knee support?

A knee support (such as a knee sleeve) is usually a tight-fitting fabric garment.

It provides compression to help reduce swelling and discomfort.

A knee brace provides much more support and may also limit mobility.

Some people only need to wear a knee brace when doing certain activities or during a flare-up of pain.

Ask your healthcare provider about when you should and should not wear your knee brace.

Summary

Knee braces can provide relief from discomfort and aid healing after an injury or surgery.

It’s important to wear a knee brace correctly and for the recommended amount of time.

If you’re not sure when to wear your knee brace, ask your healthcare provider.
