As of January 1st, 2019, we have implemented the following return policy:
Returned product will only be accepted in unused, re-saleable condition within 30 days of delivery.

Loaner Program

To provide prosthetists and amputees a more convenient way to trial the All-Terrain Knee, we developed the All-Terrain Knee Loaner Program. At this time, only the Original Series models (ATK-PA-01 and ATK-SF-01) are available as loaner product.

Prosthetists requesting to participate in the All-Terrain Knee Loaner Program will agree to adhere to the applicable guidelines and policies. Loaner knees may be ordered for trial purposes for a period of no longer than 30 days from delivery, and are not intended to function as replacements for existing equipment or for any other purpose. If your unit requires service or repair, please review the Warranty & Repairs guidelines outlined above.

If you have questions, require warranty & repair service, or would like to obtain a Loaner Application form, please call our office at (408) 692-5633 between 9:00 a.m.-6:00 p.m. ET, Monday-Friday, or email sales@legworks.com.
