DonJoy XROM Size Guide: Universal Fit Explained
What size is the DonJoy Xrom?
The Quick Answer
The DonJoy XROM comes in a **single universal size** designed to fit individuals between **4'11" and 6'11"** in height. Adjustable straps with hook-and-loop closures accommodate thigh circumferences from 14–28 inches and calf circumferences from 12–22 inches—eliminating sizing complexity while maintaining structural support through its rigid aluminum frame.
Why We Ask This
Patients worry about improper brace sizing compromising rehabilitation—either too loose (allowing harmful joint translation) or too tight (causing neurovascular compromise)—especially when standard sizing charts don't match their body proportions.
The Practical Science
Universal sizing works through modular strap systems that distribute compressive forces evenly while the rigid frame maintains consistent hinge alignment regardless of limb circumference. Biomechanical testing confirms stable patellofemoral tracking across the full size range when straps are properly tensioned.
In Clinical Practice
A 5'2" patient with muscular thighs secures the proximal strap snugly at the upper thigh mark while adjusting distal straps to prevent migration during ambulation—demonstrating how universal sizing accommodates diverse body types through strategic strap placement rather than fixed dimensions.
