Deluxe Open Knee Support
DonJoy®
Engineered for athletes demanding stability without restriction.
The open popliteal design minimizes friction, ideal for those with neoprene sensitivities or in warm climates.
Bilateral hinges and Drytex fabric deliver breathable compression, supporting ligament injuries, meniscus tears, or mild OA.

Find the Right Fit:
- Stand with feet shoulder-width apart, knees slightly bent, leg muscles gently flexed.
- Place measuring tape flat against the skin (not tight). Measure leg circumference at:
- 6 inches above kneecap
- Center of kneecap
- 6 inches below kneecap
- Use chart to find your size. If you land between sizes—or if thigh and calf measurements suggest different sizes—choose the larger option.
A correctly sized brace will feel comfortably snug and supportive without being excessively tight.
