The McDavid 429 PSII Hinged Knee Brace is a supportive hinged knee brace designed to provide stability while allowing natural knee movement during physical activity. It combines geared polycentric hinges, a padded patella buttress and adjustable straps with 4.8 mm latex-free neoprene compression, making it a strong option when you need more support than a basic knee sleeve.
The bilateral geared polycentric hinges are designed to provide stability while still allowing the knee to move freely. Rigid side uprights add medial and lateral support, which can be useful during activities involving running, jumping and changes of direction.
Around the front of the knee, the open 360° padded buttress helps isolate and support the patella. Molded condyle pads also help position the brace around the knee while providing cushioning and comfort.
The brace uses 4.8 mm latex-free neoprene, providing thermal compression around the knee. The perforated back panel helps manage heat and moisture, while bound edges are designed to reduce irritation during use.
Fit is adjusted using the integrated top and bottom straps. Reinforced pull tabs make the brace easier to put on and remove, while reinforced mesh netting helps prevent the hinges from moving out of position. The McDavid 429 can be worn on either the left or right knee.
WHO IS THE MCDAVID 429 PSII BEST FOR?
The McDavid 429 PSII is best for athletes who need a higher level of knee stability and support during physical activity. The hinged construction makes it particularly relevant when side-to-side stability and controlled knee movement are important.
It can be used across sports where the knee is exposed to running, jumping or changes of direction, but the correct level of support depends on the individual injury or condition.
WHAT SHOULD YOU CONSIDER BEFORE BUYING?
This is a structured hinged knee brace rather than a simple compression sleeve, so it is designed for customers specifically looking for additional knee support and stability.
If you are buying a knee brace because of an existing injury, McDavid advises that the brace is not a substitute for medical care. A doctor should diagnose the injury and advise on appropriate treatment.

JCPretty good. Once it is on it is comfortable and supportive. A couple of minor gripes. Because of the sleeve design i do have to remove footwear to get it on or off which is a bit inconvenient. There is also a bit of slack at the top of sleeve once the straps are done.(4.00)Published Tuesday, 15 July 2025
