The Influence of Knee Flexion Angle for Graft Fixation on Rotational Knee Stability During Anterior Cruciate Ligament Reconstruction: A Biomechanical Study

The effect of short-graft preparation with tape suspension and screw fixation on loss of knee extension following anterior cruciate ligament reconstruction: A retrospective cross-sectional analysis of public hospital cases from 2015 - 2017

“…Our results are consistent with previously reported LOE after ACLR (Table 4). Previous studies have attributed LOE to, among others, graft placement and fixation, impingement within the intercondylar notch, immobilisation prior to rehabilitation and early ACLR post-injury [5][6][7] . There is notable variability in LOE within all timepoints in Table 4, reinforcing the concept that LOE is multifactorial.…”

“…One other common post-operative complaint after ACLR is reduced range of knee motion (ROM), in particular loss of extension (LOE), which may present a greater functional limitation than pre-operative instability [5] . Previous studies have investigated factors affecting LOE, including surgical technique, however few have been able to definitively identify significant contributors to maximising knee ROM [5][6][7] .…”

Graft Retensioning by Dialing of Suture Disk on Tibial-Side Fixation in Arthroscopic Anterior Cruciate Ligament Reconstruction: Pathak Pune Dialing Technique

“…The success of arthroscopic ACL reconstruction depends on several factors, including graft tension during fixation, 4 type and source of the graft, 5 tunnel position, 6 knee flexion angle at the time of fixation, 7 method of graft fixation, 8 and initial graft tension at the time of fixation. 9 Of these variables, the amount of tension applied during graft fixation has been hypothesized to be an important determinant of successful ACL reconstruction.…”

No proof for the best instrumented device to grade the pivot shift test: a systematic review

“…The latter systems, using electromagnetic fields to three-dimensionally locate the position of specific sensors placed on the skin (and therefore showing no clinical invasiveness when compared with navigation), were the first ones used in the outpatients settings. Owing to their lower costs, encumbrance and easiness of use, the second wave of research led to the use of accelerometers21 34 (ie, devices able to quantify the acceleration of an object which they are attached to), gyroscopes21 35 (ie, devices able to quantify the angular velocity of an object which they are attached to) and combined solutions—like the inertial measurement unit (IMU)21 36–38—which are able to read at the same time both acceleration and angular velocity and—through data fusion—to estimate the orientation of the limb in space. From the most technical point of view, electromagnetic systems are able to provide all the six degrees of freedom of a rigid body in a global reference system.…”
