<p class="abstract"><strong>Background:</strong> Accurate tunnel positioning in anterior cruciate ligament reconstruction surgery is one of the cornerstones for its success. However, it is still controversial and target of disagreement within the orthopedic literature. Therefore, it was aimed to evaluate the tibial tunnel placement in anterior cruciate ligament reconstruction surgeries of a single orthopedic surgeon.</p><p class="abstract"><strong>Methods:</strong> The postoperative knee sagittal radiographs of anterior cruciate ligament reconstructed knees from a single surgeon were retrospectively collected. To assess the tunnel positions was used predefined criteria (in percentage and in millimeters) within the intervals found in the literature (41-43 percent and 21-23 millimeters).<strong></strong></p><p class="abstract"><strong>Results:</strong> There were no significant differences between the number of results (% and mm), within and without the intervals that were considered acceptable for this measure (P &gt;0.05). It was found significant differences in the absolute deviation (%) throughout non-consecutive years (P &lt;0.05). There was no correlation between the absolute deviations and the years of experience (r =-0.080, P =0.663).</p><p><strong>Conclusions:</strong> Significant differences were found in the absolute deviation (%) throughout non-consecutive years, suggesting variations in the tunnel position throughout the years. </p>

Abstract Background The interference screw is the most popular device that fixes the graft for anterior cruciate ligament reconstruction, reducing the incidence of windshield effect and bungee effect. For the screw, either metallic, “bioresorbable,” or polyetheretherketone (PEEK) material is available. PEEK is popular and extensively used due to its stability, biocompatibility, radiolucency, and elastic modulus. Rare relevant complications were reported, but here, we report two cases of extra-articular migrations of PEEK interference screw from the tibial tunnel after anterior cruciate reconstruction. Case report An 18-year-old boy and a 56-year-old woman underwent anterior cruciate ligament reconstruction using a PEEK interference screw to fix the graft in the tibial tunnel. They suffered from screw extrusion from the tibial tunnel after 40 days and six months, respectively, with an incision rupture or palpable subcutaneous mass. They underwent a second operation and recovered well. Conclusions The exact incidence of extra-articular migrations of PEEK interference screws is unknown, but it seems to be quite low; despite this and its uncertain cause, the negative effects caused by the PEEK material need to be considered.
