The patella knee brace also reduces edema swelling through its compression affects around the knee. This Bauerfeind patella brace also features spiral stays, located on both sides of the knee, to help maintain the shape of the knit and enhance overall knee support and brace suspension on the leg. The knee support has a special, non-irritative weave in the critical area behind the knee prevents bunching and pinching of brace material with heavy use.
