Size & Fit
Use a soft measuring tape and measure your thigh circumference 5.5 inches / 14 cm above the kneecap. This is the most important measurement for choosing the correct size. Do not choose your size based only on height, weight, or regular pants size.
Choose the smaller size if you prefer a firmer compression feel. Choose the larger size if you prefer more comfort for longer wear.
The brace should feel snug and supportive, not painful or restrictive. If you feel numbness, tingling, or unusual discomfort, remove the sleeve and adjust your size choice.

How It Supports？
— Patella Gel Pad Protection
Professional-grade silicone gel ring fully surrounds and encapsulates your kneecap, absorbing shock, reducing pressure, and preventing patellar misalignment during explosive movements.
— Horizontal Knit Technology (Exclusive Patent)
Anatomically contours to your knee's natural curves, delivering precise, graduated compression exactly where your muscles and joints need it most.
— Double-Sided Spring Stabilizers
Flexible metal stabilizers run down both sides of the knee, offering robust lateral support to reduce shearing forces while retaining full range of motion.
— Active Anti-Slip
Anti-slip Silicone Dots at the top cuff keep the sleeve locked in place all day—zero sliding, zero rolling, even during heavy sweat.
Frequently Asked Questions
Each package includes one ACE-39 knee brace. It can be worn on either the left or right knee.
The ACE-39 provides Balanced support. It offers more structure than a basic compression sleeve while remaining lighter and more flexible than a rigid hinged brace.
The ACE-39 is a flexible compression sleeve with patella cushioning and side stabilizers. A rigid hinged brace provides stronger structural restraint but is heavier and less flexible. Follow your healthcare professional’s recommendation when choosing a brace for a diagnosed injury or after surgery.
The ACE-39 provides supportive compression and cushioning for everyday movement. It does not treat arthritis. Consult a healthcare professional if you are unsure whether compression support is appropriate for your condition.
Some customers use compression support while awaiting treatment or during later-stage recovery. The ACE-39 is not a post-operative immobilizer or range-of-motion brace. Use it after surgery only when approved by your healthcare professional.
Measure your thigh circumference 5.5 inches (14 cm) above the center of your kneecap and compare the measurement with the size chart. Do not select a size based only on height, weight, or usual clothing size.
Choose the smaller size for firmer compression or the larger size for a more relaxed fit. The brace should feel secure without causing numbness, tingling, pinching, or restricted circulation
The ACE-39 uses flexible side stabilizers rather than rigid metal hinges.
