Compression Hosiery Knitting and Graduated Pressure
topic
Medical compression hosiery knitting uses elastane or rubber core yarn with programmed stitch density variation from ankle to thigh to achieve graduated compression profiles of 15 to 40 millimetres of mercury at the ankle decreasing to 50 to 70 percent at the knee as required by medical compression standards, with compression level certification requiring measured pressure profile compliance verified by pneumatic testing on standard leg forms.
Role
Produces medically certified compression hosiery for venous insufficiency, lymphedema, and post-thrombotic syndrome treatment where the graduated compression profile delivering higher pressure at the ankle than thigh drives venous blood return against gravity, with precise pressure profile control through stitch density and elastane tension programming being the critical technical requirement for medical certification compliance.
