Thank you for viewing. Shipping is free. Size: 2 Type: Right knee joint only Color: Titanium *Please refer to the last image for sizing. Please check the manufacturer's website for details. *This supporter is specifically designed for either the left or right side, so the types are different. Please be careful when purchasing. I mainly used it for cycling. As you can see in the images, there are two places where the adhesive has come off, but there are no problems with using it. How about it? The old type of BAUERFEIND GenuTrain P3 is a high-quality knee support made in Germany, specializing in patellar stabilization. "P3" stands for Permanent Patella Protection and is designed primarily for people who have problems with their kneecap slipping or pain associated with it. Features and Functions (Old P3) Patellar correction and tracking improvement A special silicone pad and an adjustable correction strap are placed to prevent the kneecap from slipping outward. The main feature is its ability to guide the kneecap to the correct position. Strong compression Compared to the standard "GenuTrain," it is designed to be longer at the top and bottom, and the compression is also set stronger. Muscle activation and pain relief The silicone pad stimulates the muscles around the knee joint (especially the vastus medialis) during exercise, helping to stabilize the joint. The massage effect promotes the reduction of knee pain and edema. Relieves outward traction A muscle relaxation pad is installed to loosen the tensor fasciae latae, reducing the force that pulls the kneecap outward. Differences between the old type and the standard GenuTrain Purpose: GenuTrain is for "arthritis and instability." P3 specializes in problems with the kneecap, such as "iliotibial band syndrome, patellar dislocation, and jumper's knee." Shape: P3 is about 2.5 inches longer than the standard type and provides firm support up to the thigh.
