Female Fource - OTS

Female Fource - OTS

Females are 3-8 times more likely to sustain an ACL tear than males. In addition, over 70 percent of all ACL injuries occur during non-contact activities, such as cutting, jumping and twisting maneuvers. The DonJoy Female Fource addresses biomechanical factors that have been implicated in the high incidence of anterior cruciate ligament (ACL) tears in females. Females tend to perform cutting and landing maneuvers with their knees and hips in an extended and less protected position. The Female Fource incorporates DJO's FourcePoint hinge technology, which has been clinically demonstrated to increase knee flexion angles, limiting the time the knee spends in at-risk positions during activity; therefore, providing females the protection they need.

The Female Fource is the first functional knee brace to come with a custom graphics sticker sheet to allow patients to personalize their braces to their own liking. In addition, with nearly 212,000 females being diagnosed with breast cancer and approximately 40,000 losing their life from the disease in 2005, DonJoy will be contributing to breast cancer initiatives.

DonJoy's OTS Female Fource is a lightweight, low profile functional knee brace designed specifically for females and is perfect for the active female returning to sport or the general female population returning to activities of daily living where an OTS brace is required.

Where to Buy


My DonJoy Female Force has been there with me while going through the hardest thing in my life. I tore my ACL and meniscus almost a year and a half ago while pitching. The rehab was tough. Being away from my teammates was tougher. Being away from fastpitch, the game I love, for almost 9 months was the toughest. I used my DonJoy through the rehab, on my first game back, and still to this day. I am so thankful for the peace of mind and confidence my DonJoy brace gives me to go out and be the best I can for me, my teammates, my coaches, and my family. Thank you DonJoy!”
