Modified arthroscopic suture fixation of displaced tibial eminence fractures using a suture loop transporter

Current arthroscopic suture fixation techniques of tibial eminence fracture s are time consuming and the number of anchor sutures that can be placed is limited by the cumbersome and repetitive numerous needle threading steps. This occurs at 2 stages: first, when placing anchoring sutures through the avulsed anterior cruciate ligament stump with a suture punch, and second, w hen there is a need to traverse the tibial bone canal with the suture ends. We describe a modification that reduces the reliance on conventional rigid instruments and instead uses a loop transporter made from readily availabl e suture material. The suture loop transporter being malleable reduces the necessary width of the tibial bone canal to be made and has a further advan tage of minimizing the bone loss during the reaming of the bone tunnel. The subsequent potential for a stress fracture at these tunnel sires is also s ubstantially reduced. Our technique is more user friendly, more accurate, a nd quicker to perform.
