Key Features

The Guardian™ Knee by College Park is a lightweight mechanical knee joint, suited to low-impact users learning to stand and walk in rehabilitation. It features a friction brake for stance control and extension assist.

Designed with the clinician and user in mind, it can be easily adjusted for gait matching without having to remove the prosthesis. As the patient progresses, the remote lock feature can be disengaged, allowing the knee to operate as a single knee axis joint and providing the full 145° of anatomical motion.
