Mode of Operation

The Jack PCL Brace overcomes the gravity of the lower leg to relieve the posterior cruciate ligament. The translation force may be adjusted to the leg and weight of the patient through setting the tension on both sides of the brace. Hereby the detrimental effects of the muscle and gravitation forces can be counteracted. The slipping of the tibia into the posterior drawer position is inhibited.

The idea behind the Jack PCL Brace

The problem: Posterior drawer position caused by gravity or the activation of the ischiocrural muscles.

The solution: Constant anterior directed translation force.
