How to measure for Otto Bock Derma Protection Knee sleeve.

STEP 2: Find your size

Take your thigh circumference and use the chart to determine your size. If you're in-between sizes, we suggest remeasuring again to be on safe side.

1 24-32 30
2 30-40 32
3 34-44 33
4 42-56 33

When measuring your thigh, pay special attention to how tight you take your measurement. It's best to pull the ends of your tape measure somewhat tight and then release. Your goal is to find a middle ground of how much tension you should apply to your measuring tape. Too tight and too loose will both result in a poorly fitting prosthetic sleeve.
