Key Features

The Guardian Knee by College Park is a lightweight mechanical knee joint, suited to low-impact users, and as a rehabilitation tool for new patients learning to stand and walk.

It features a friction brake for stance control and extension assist for full extension when walking, which can all be easily adjusted for a natural gait without having to remove the prosthesis.

The remote lock feature can be disengaged to provide the full 145° of anatomical motion as the patient progresses, allowing the knee to operate as a single knee axis joint.
