CTi®3 Size Guide
Knee width (M/L) is the primary measurement for determining CTi®3 size. Thigh circumference can be used as an additional measurement, particularly when the knee measurement falls between sizes.
| Size | Knee Width (M/L) | Thigh Circumference |
|---|---|---|
| Small | 8.9–10.2 cm / 3.5–4 in | 40–47 cm / 15.7–18.5 in |
| Medium | 10–11.4 cm / 3.9–4.5 in | 45–55 cm / 17.7–21.7 in |
| Large | 11.2–12.7 cm / 4.4–5 in | 52–61 cm / 20.5–24 in |
| X-Large | 12.5–14 cm / 4.9–5.5 in | 58–67 cm / 22.8–26.4 in |
How to Measure: Measure the width of the knee at the joint line while standing in a normal weight-bearing position. For the secondary measurement, measure the circumference of the thigh 20 cm (8 inches) above the center of the kneecap.
