The Compass Knee Hinge can be a useful part of the treatment regimen for highly unstable knee dislocations.
Step 1: Initial Alignment of Wires
Make sure to place the centering wire at the isometric point of the knee.
Step 2: Placement of the Compass Knee Hinge
Take the necessary steps to place the Compass Knee Hinge over the wire.
Step 3: Application of the Compass Knee Hinge with Concurrent Procedures
If repair or reconstruction of either the posteromedial or the posterolateral corner is part of the planned surgical procedure, place the centering wire prior to the repair or reconstruction of the injured corner.
Step 4: Postoperative Protocol
Postoperatively, use progressive protocols to enable the patient to regain knee motion following the application of the hinge.
The above technique was used to treat fifty-five patients with a total of fifty-six knee dislocations who had various concurrent ligamentous reconstructions14.
