Crossover™ Extensible Knee

“Infinite Possibilities”

Congratulations on your decision to purchase a Crossover™ Extensible Knee! We have taken our original

Bartlett Tendon Knee (BTK) design and made it even better! The new Crossover™ is an ambulatory Extensi-

ble knee that transforms into a sports knee in less than three minutes!

This state-of-the-art prosthetic knee system will be very gratifying if you service and maintain it accordingly.

Please enter the serial numbers of your knee below. You will provide this number if the knee unit requires

servicing. Serial numbers are located on the knee frame under the protective cover.

ences due to developments in the knee design cannot be ruled out completely.
