Ortho Lower Size Guide
Helpful tips for finding the proper support size for your patient
Waist circumference (waist size).
Measure around the middle of the waist.
Knee circumference. Measure around the knee. Instructions might state with knee slightly bent.
Ankle joint circumference. Around the joint from top of the ankle to under the heel.
The Knee Joint ACL PCL
Hip circumference. Measure around the largest part of the hips.
Knee above and below measure- ments. The top tape represents 51⁄2” above mid-knee and the lower tape represents 41⁄2” below mid-knee. *Please note the distance above and below may differ by style of brace and instructions will specify where to take the measurements. You then measure around that portion to obtain the proper circumference.
Cruciate ligaments
Stabilizes the femur on the tibia.
• Anterior Cruciate Ligament (ACL) pre- vents the tibia from rotating and sliding forward.
• Posterior Cruciate Ligament (PCL) pre- vents the tibia from rotating and sliding to the rear.
Collateral ligaments
Support the medial (MCL) and lateral (LCL) sides of the knee joint.
Patellar ligament (dotted lines)
Connects the knee cap to the tibia. (In jumper’s knee, this ligament is partially ruptured)
Meniscus
Cartilage of the knee joint located between the femur and the tibia. Medial meniscus lies on the medial plateau and the lateral meniscus lies on the lateral tibial plateau.
Thigh circumference. Measure around middle of thigh muscle, or the widest part of the thigh.
Calf/Ankle circumference. Top mea- surement is the calf circumference and the bottom measurement is the ankle circum- ference.
