A Review of the Gillquist Maneuver: Modifications for a Safer and Easily Reproducible Approach for Knee Transintercondylar Notch Posterior Compartment Arthroscopy

The original Gillquist maneuver is done by passing the arthroscope through a portal in the patella tendon between the medial femoral condyle and posterior cruciate ligament to enter the posterior compartment. This is done blind and has been documented to result in broken cameras and damaged equipment. It is also necessary to do a notchplasty to aid the advancement of the camera in patients. In our paper, we have made modifications to allow the Gillquist maneuver to be done safely under direct visualization, with just the aid of a simple switching stick. Our technique starts with the arthroscope in the anteromedial portal. We insert a long, cannulated switching stick through the anterolateral portal and pass it between the medial femoral condyle and the posterior cruciate ligament. The switching stick, being tapered and narrow, is able to traverse the transcondylar notch with minimal trauma. Once the switching stick enters the posterior compartment, the camera and trocar are removed and the trocar sleeve is guided over the switching stick past the intercondylar notch gently. The switching stick is then replaced by the arthroscope, which is advanced through the trocar sleeve and into the posterior compartment.
