Knee straps and braces can be helpful for preventing knee injuries, especially if you're prone to injury or have recently recovered from a knee injury. You can ask your physiotherapist about the knee straps they recommend and how to wear them safely. Knee straps and braces keep your knee joint stabilised to prevent knee injuries that occur when the ligaments in your knee are overextended or destabilised. Still, it's important to always warm-up, cool down and work to increase your joint mobility, in addition to wearing a knee strap during netball play.
