Measuring and Sizing

Measurement and Sizing

Measure at three points on the leg and use the chart to determine the size required. Watch a video to help.

  • Thigh 15cm above mid-patella (kneecap)
  • Knee, mid-patella (kneecap)
  • Calf 15cm below mid-patella (kneecap)

If one of the three measurements is a size up, select that size

  • For example, Thigh Size 2, Knee Size 3, Calf Size 2. Order Size 3

Note that the off-loading hinge is located on the opposite side of the affected compartment.
