Athletes and those who engage in vigorous physical activities are usually prone to knee joint pains. Knee pains are sharp pains that are localized around the knee joints (connecting bones, kneecap, and ligament or cartilages). The pains can be so devastating that one can be deterred from engaging in his or her cherished exercises or workouts. One particular workout that exacerbates this condition is performing squats. Apart from other topical applications to ease pains, wearing knee braces has been found very helpful. These braces configured to claps around your knee to keep it warm and lubricated. In essence, they help lessen joint pain while bringing some stability to the knee. However, knee braces will not help prevent knee joint pain during squat as they only help to keep off pressure from your knee.
They will definitely stabilize your knee joints but the main thing that can prevent joint pain/injury is your form. So make sure to perfect your squatting form first!
