The authors compared the intraoperative navigated measurements of the location of the tibial and femoral tunnels during arthroscopic-assisted anterior cruciate ligament reconstruction to the postoperative measurements performed on standard plain radiographs in 56 patients. The position of the center of the tibial and femoral tunnels was measured intraoperatively with the OrthoPilot (B. Braun Ae...

OBJECTIVES To compare the accuracy of tunnel placement and graft isometry for anterior cruciate ligament reconstruction performed using a computer-assisted navigation system (Orthopilot) and using traditional instruments. METHODS The anterior cruciate ligament was removed intact from 36 pairs of human cadaver knees. From each pair, one knee was randomized to Group 1 (conventional) and the oth...

BACKGROUND Anatomic double-bundle reconstruction has been thought to better simulate the anterior cruciate ligament anatomy. It is, however, a technically challenging procedure, associated with longer operation time and higher cost. HYPOTHESIS Double-bundle anterior cruciate ligament reconstruction using a single femoral and tibial tunnel can closely reproduce intact knee kinematics. STUDY ...

Tarsal Tunnel Syndrome is the term used to designate the compression of the posterior tibial nerve within the tunnel or of one of its terminal branches leaving the tunnel. This syndrome is due to a neurogenic cause and affects the area supplied by the tibial nerve. The tibial nerve has three branches: the medial plantar nerve, the medial lateral nerve, and the medial calcaneus nerve. The osteof...

We describe a surgical technique for arthroscopic posterior cruciate ligament (PCL) reconstruction with remnant preservation of the original PCL fibers using a posterior trans-septal portal approach. Using the transtibial technique and the posterior trans-septal portal approach allows good visualization of the tibial tunnel preparation, easy access to the tibial tunnel without neurovascular inj...

BACKGROUND Bone tunnel enlargement is a phenomenon present in all anterior cruciate ligament (ACL)- reconstruction techniques. It was hypothesized that press-fit fixation using a free autograft bone plug reduces the overall tunnel size in the tibial tunnel. METHODS In a prospective cohort study twelve patients who underwent primary ACL reconstruction using an autologous quadriceps tendon graf...

BACKGROUND Surgical reconstruction of the anterior cruciate ligament (ACL) can be complicated by incorrect and variable tunnel placement, graft tunnel mismatch, cortical breaches, and inadequate fixation due to screw divergence. This is the first report describing the use of a C-arm with image intensifier employed for the sole purpose of eliminating those complications during transtibial ACL re...

Purpose The effect of sagittal plane angle of the tibial tunnel on the severity of tibial intra-articular aperture expansion caused by iatrogenic re-reaming in anterior cruciate ligament (ACL) reconstruction using a modified transtibial technique is unknown. The purpose of this study was to compare the severity of intra-articular aperture widening at different angles (40°, 45°, and 50°) of the ...

PURPOSE Proper femoral tunnel position is important for anatomical reconstruction of the anterior cruciate ligament (ACL). The purpose of this study was to evaluate the positions of femoral and tibial tunnels created using an accessory anteromedial portal technique in single bundle ACL reconstruction. MATERIALS AND METHODS The femoral tunnel was targeted at the mid-portion of the ACL bundles....

AIM To quantitatively assess rotatory and anterior-posterior instability in vivo after anterior cruciate ligament (ACL) reconstruction using bone-patellar tendon-bone (BTB) autografts, and to clarify the influence of tunnel positions on the knee stability. METHODS Single-bundle ACL reconstruction with BTB autograft was performed on 50 patients with a mean age of 28 years using the trans-tibia...
