How to Measure
Knee Width (Primary Measurement)
Measure the M/L width of the knee at the joint line while standing in a normal weight-bearing position. Knee width should be used as the primary measurement when selecting your CTi®3 size.
Thigh Circumference (Secondary Measurement)
Measure around the thigh 20 cm (8 inches) above the center of the kneecap while standing. This measurement can be used as an additional sizing reference, especially when your knee-width measurement falls between sizes.
Between Sizes?
If your measurements fall between two sizes, use your knee-width measurement as the primary sizing reference and compare your thigh circumference for additional guidance.
