“…Previous studies showed that tibial tunnel placement in the anterior aspect of the native footprint confers increased sagittal graft obliquity and improved control of ATT after ACLR [25,32,43] but this may lead to notch impingement [25,32]. Maak et al showed that the AM tibial socket combined with the femoral socket into a more central position may reduce the risk of impingement [24].…”

“…Postop-erative ACL impingement on the PCL has not been extensively studied. Studies have shown that abnormal contact between the different ligamentous structures might explain the joint pain, impaired flexion, and instability following ACL-r. 84,85 In this respect, minor variations in positioning of the tibial and femoral tunnels can result in abnormal impingement of the graft on the PCL. This contact can be observed in up to 10% of asymptomatic patients.…”

The growing number of patients undergoing arthroscopy or surgery of the knee for ligamentous injuries has led to a greater need for postoperative imaging because of poor outcome, recurrent symptoms, or a new injury. MRI is the most important imaging method when evaluating the postoperative knee. Radiologists should be familiar with the particular reconstruction technique applied to each examinee, know the spectrum of normal postoperative findings, recognize those findings that may be related to symptoms of failed reconstruction, as well as those lesions that are irrelevant to the previous surgery yet responsible for the new clinical symptoms. In view of the continually evolving surgical techniques, this review presents the current concepts of MRI evaluation of the postoperative knee ligaments based on recent literature reports.

“…Ruptures of the ACL with direct or indirect sequelae, such as meniscal tears, are predisposing factors for the development of OA. Morbidity at the harvest zone, loss of proprioception, elongation and progredient loosening are further unsolved complications of ACL reconstruction [23][24][25][26][27].…”

Background Anterior cruciate ligament (ACL) injury can lead to reduced function, meniscal lesions, and early joint degeneration. Preservation of a torn ACL using the Internal Brace technique might re-establish normal knee kinematics, avoid donor-site morbidity due to tendon harvesting, and potentially maintain proprioception of the knee. Methods Fifty subjects were recruited for this study between December 2015 and October 2016. Two groups of individuals who sustained a unilateral ACL rupture were included: those who underwent surgery with preservation of the injured ACL (Internal Brace technique; IB) and those who underwent ACL reconstruction using a hamstring tendon graft (all-inside technique; AI). Subjective self-administered scores were used: the German version of the IKDC Subjective Knee Form (International Knee Documentation Committee), the German version of the WOMAC (Western Ontario and McMaster Universities Arthritis Index), SF-36 (short form), the German version of the KOOS (Knee Osteoarthritis Outcome Score), and the German version of themodified Lysholm Score by Lysholm and Gillquist. Anterior tibial translation was assessed using the KT-1000 Arthrometer (KT-1000 Knee Ligament Arthrometer, MEDmetric Corp., San Diego, CA, USA). Magnetic resonance evaluation was performed in all cases. Results Twenty-three subjects (46 %) were men, and the mean age was 34.7 years. The objective IKDC scores were “normal” in 15 and 14 patients, “nearly normal” in 11 and 7 patients, and “abnormal” in 1 and 2 patients, in the IB and AI groups, respectively. KT-1000 assessment showed a sideto-side difference of more than 3 mm on maximum manual testing in 11 (44 %) and 6 subjects (28.6 %) in the IB and AI groups, respectively. In the postoperative MRI, 20 (74 %) and 22 subjects (96 %) in the IB and AI groups had an intact ACL. Anterior tibial translation was significantly higher in the IB group compared with the AI group in the manual maximum test. Conclusions Preservation of the native ACL with the Internal Brace primary repair technique can achieve comparable results to ACL reconstruction using Hamstring autografts over a short term. Clinically relevant limitations such as a higher incidence of pathologic laxity, with patients more prone to pivot-shift phenomenon were observed during the study period.

Effect of Femoral Socket Position on Graft Impingement After Anterior Cruciate Ligament Reconstruction

Abstract: Anatomic femoral socket position in the center of the native ACL footprint may reduce the risk and magnitude of notch impingement compared with an anteromedial bundle position with ACL reconstruction.
