Which GenuForce® knee brace size is recommended for a knee circumference (measurement A) of 37 cm?
For a knee circumference (measurement A) of 37 cm, you are at the boundary between sizes L (34-37 cm) and XL (37-40 cm) for the GenuForce® knee brace. Size L could be chosen for more pronounced compression, or Size XL if a slightly looser fit is preferred or if you are at the upper limit of Size L.
