“…It has been reported that steeper lateral PTS increases force on the graft, 27 and it could affect both femoral and tibial TW. However, in view of the results of the current study, lateral PTS had a large effect on tibial TW, whereas other factors such as graft bending angle, tunnel location, age, or bone quality had a large effect on femoral TW, 28 , 29 , 30 suggesting that the effect of lateral PTS was relatively small in this study.…”

“…Previous studies have reported various factors associated with residual pivot-shift after ACLR, such as younger age [15,16], medial and lateral meniscus tears [15,17,18] , concomitant grade 2 medial collateral (MCL) injury [19], hyperextension of the knee [20], preoperative large pivot-shift phenomenon [18, 20-5 22], and period from injury to surgery [18,19,23]. However, surgical procedures were not consistent in the previous literature, and few studies have comprehensively examined the risk factors of postoperative residual pivot-shift after anatomic DB-ACLR.…”

Introduction: Although anterior cruciate ligament reconstruction (ACLR) is considered a successful procedure, residual pivot-shift after surgery remains to be solved. The purpose of this study was to comprehensively evaluate the risk factors of residual pivot-shift after anatomic double-bundle (DB)-ACLR.Materials and Methods: A total of 164 patients who underwent primary anatomic DB-ACLR between January 2014 and December 2019 and screw removal after the index ACLR in our hospital were included in this retrospective case-control study. The manual pivot-shift test was performed under general anesthesia during screw removal surgery, and patients with grade 1 or higher pivot-shift were classified as the positive pivot-shift group, and those with grade 0 were defined as the negative pivot-shift group. Univariate and logistic regression analyses were performed to identify the factors associated with postoperative residual pivot-shift. Assessment included sex, age, time to surgery, preoperative Tegner activity scale, preoperative pivot-shift grade, preoperative anterior tibial translation by the KT-2000 arthrometer measurement, meniscus injury and its surgical procedure, knee hyperextension, cartilage damage, Segond fracture, medial and lateral posterior tibial slope, lateral -medial slope asymmetry, participation in pivoting sport/activity at the time of injury, and return to sports at postoperative one year. Line Results: Postoperative positive pivot-shift was observed in 14 (8.5%) of 164 patients. The KT-2000 measurement at 1-year postoperatively was significantly higher in the residual pivot-shift positive group than in the negative group (P < 0.05). Logistic regression analysis revealed that patients < 20 years of age 3 [P < 0.05, odds ratio (OR): 6.1)], preoperative pivot-shift grade (P < 0.05, OR: 4.4), and hyperextended knee (P < 0.05, OR: 11.8) were risk factors of postoperative pivot-shift. There were no statistically significant differences between other variables. Conclusions: Patients < 20 years of age, with high-grade preoperative pivot-shift, or hyperextended knees had a higher risk of residual postoperative pivot-shift.

“…In this study, we used the distance of anterior tibial translation of the diseased knee to evaluate its anterior instability, instead of a side-to-side difference as in other previous studies [9,[21][22][23]. In our institution, MRI is performed only on diseased knees in most cases.…”

We sought to design a computer-assisted system measuring the anterior tibial translation in stress radiography, evaluate its diagnostic performance for an anterior cruciate ligament (ACL) tear, and assess factors affecting the diagnostic accuracy. Retrospective research for patients with both knee stress radiography and magnetic resonance imaging (MRI) at our institution was performed. A complete ACL rupture was confirmed on an MRI. The anterior tibial translations with four different methods were measured in 249 patients by the designed algorithm. The diagnostic accuracy of each method in patients with all successful measurements was evaluated. Univariate logistic regression analysis for factors affecting diagnostic accuracy of method four was performed. In the inclusive 249 patients, 177 patients (129 with completely torn ACLs) were available for analysis. Mean anterior tibial translations were significantly increased in the patients with a completely torn ACL by all four methods, with diagnostic accuracies ranging from 66.7% to 75.1%. The diagnostic accuracy of method four was negatively associated with the time interval between stress radiography and MRI as well as force-joint distance on stress view, and not significantly associated with age, gender, flexion angle, intercondylar distance, and force-joint angle. A computer-assisted system measuring the anterior tibial translation in stress radiography showed acceptable diagnostic performance of complete ACL injury. A shorter time interval between stress radiography and MRI as well as shorter force-joint distance were associated with higher diagnostic accuracy.
