Dimensions
Extended description
The ST433D knee brace is designed to provide a combination of mechanical stability, motion control, and targeted load reduction at the knee joint. The open structure allows for easy dressing even in situations of pain, swelling, or limited knee flexion, without the need to dress through the foot.
The dual hinges on both sides of the joint help direct the movement of bending and straightening while reducing lateral loads and shear forces, Thus contributing to a sense of security in movement in patients with ligament instability or after rotational injuries.
The silicone pad around the patella provides peripheral support for the soft tissues, helps reduce direct load on the patella, and improves local proprioception. This combination may contribute to reducing anterior knee pain and improving muscle control around the joint.
The protector is suitable for use in various stages of rehabilitation, in daily activities, as well as in stages of gradual return to physical activity, according to the guidance of a professional.

Meniscus or rotator cuff injury. It is not intended to allow immediate return to
For intense activity without rehabilitative control.
Progress should be made based on indicators of pain, swelling, range of motion, and motor control.
Cartilage erosion (OA)
May reduce pain during activity, but it is important to be careful to perform strength training,
Balance and adapted aerobic endurance training.
Guiding principle
The protector is designed to allow safer movement – not replace muscle work.
