عنوان انگلیسی Tibial Tunnel Preparation in Posterior Cruciate Ligament (PCL) Reconstruction. A Technical Tip to Lessen the Stress
چکیده انگلیسی مقاله Abstract Purpose: To introduce a technical tip for the preparation of tibial tunnel in PCL reconstruction to reduce the chance of popliteal artery injury and to decrease the duration of the surgery. Method: Eighteen patients who underwent PCL reconstructions at our institution between 2016 and 2017 were included in this study. In all patients, the PCL tibial aimer device inserted from anteromedial portal and its tip aimed 8-9 mm below shiny white fibers in PCL facet. The smooth guide pin then was inserted from anteromedial tibial cortex and advanced just to the posterior cortex but not through it, based on measurement of tibial tunnel length. Thereafter reaming was done over the guide pin. As the pin was engaged in the posterior cortex we were sure that it would not run before reamer to the popliteal fossa. We remove the pin when the reamer touched the posterior cortex and then continue reaming until reamer's head appeared in the PCL facet. Other steps of standard arthroscopic PCL reconstruction were done. We did CT scan evaluation of all patients. Results: The mean age of the patients in this study were 25(+- 3y). The mean duration of surgery was 95 minutes. There was no vascular injury. The position of tibial tunnel in all cases were accurate. The mean distance between the center of the tibial tunnel to CGD(Champagne_ glass Drop-off ) the posterior cortex of tibia was 7.42 mm (range from 4.6 to 10.4 mm). Conclusion: Our study showed that avoiding the penetration of posterior cortex of the tibia by means of the pin during tibial tunnel preparation for PCL reconstruction is a safe, reproducible and time saving technique. Using this technique eliminates the need for fluoroscopy during the procedure.
