Description
The Circleg Transfemoral Prosthetic Kit is a complete modular above-knee prosthetic system supplied as a single order: the Circleg Polycentric Knee, Circleg Dynamic Foot and Circleg TF Cosmetic Cover, with or without the Circleg 250mm Pylon Kit. Developed in Switzerland for demanding environments and diverse patient populations, it gives prosthetic clinics a dependable, clinically proven transfemoral build at a fraction of the cost of premium imported components.
The fully mechanical design has no electronics, needs no scheduled maintenance and uses standard pyramid connections throughout. Adjustable sizing, a bilateral foot and interchangeable parts mean a small number of kits can serve a wide range of users, cutting component stock by up to 80% and prosthetic finishing time by up to 70%.
Choose the cover size to match the user's height, the foot size to match foot length and body weight, and whether the kit should include the pylon. Kits without the pylon suit clinics that already stock their own tube adapters.
