Abstract
PURPOSE To investigate the effects of ramp lesion (RL) and its repair on knee instability in patients with anterior cruciate ligament (ACL) injury by quantitatively assessing anteroposterior and rotational knee instability before and after ACL reconstruction. METHODS All primary double-bundle ACL reconstructions using hamstring autografts between 2016 and 2021 were evaluated retrospectively. Patients with RLs without other meniscal injuries were included in group R, whereas those with isolated ACL injuries constituted group C. RL was repaired using all-inside devices in all patients in group R. Knee instability, including the amount of anterior tibial translation (ATT), and the acceleration and external rotational angular velocity of the knee joint (ERAV) during the pivot-shift test were assessed at the time of surgery. The pivot-shift test grade was recorded. RESULTS A total of 73 patients were included in this study. Preoperatively, group R (n = 23) had significantly greater pivot-shift grades (P = .039), ATT (6.0 mm, group R; 4.5 mm, group C, P < .001), acceleration (6.8, 2.8; P = .037), and ERAV (3.9, 2.8; P = .001) than group C (n = 50). Intraoperatively, ATT (-1.0 mm, -1.0 mm; P < .001), acceleration (1.2, 1.1; P < .001), and ERAV (1.4, 1.2; P < .001) were significantly decreased compared with the preoperative values in both groups. No significant differences in these values were observed between groups R and C. CONCLUSIONS ACL-injured knees accompanied by RLs exhibited significantly greater anteroposterior and rotatory instability than knees with isolated ACL injuries; increased knee instability can be effectively addressed by performing RL repair in conjunction with ACL reconstruction. The quantitative assessments employed-specifically measuring ATT, acceleration, and ERAV during the pivot-shift test-have allowed us to delineate these aspects of knee instability with greater precision. LEVEL OF EVIDENCE Level Ⅲ, retrospective comparative study.

Abstract
Background: It is still uncertain how surgical reconstruction of the anterior cruciate
ligament (ACL) is able to restore rotatory laxity of the involved joint. The
desired amount of restraint applied by the ACL graft, as compared with the
healthy knee, has not been fully clarified. Purpose: To quantify the ability of single-bundle anatomic ACL reconstruction using
hamstring tendons in reducing the pivot-shift phenomenon immediately after
surgery under anesthesia. Study Design: Case series; Level of evidence, 4. Methods: An inertial sensor and image analysis were used at 4 international centers to
measure tibial acceleration and lateral compartment translation of the knee,
respectively. The standardized pivot-shift test was quantified in terms of
the side-to-side difference in laxity both preoperatively and
postoperatively with the patient under anesthesia. The reduction in both
tibial acceleration and lateral compartment translation after surgery and
the side-to-side difference were evaluated using the Wilcoxon signed-rank
test. Alpha was set at P < .05. Results: A total of 107 patients were recruited for the study, and data were available
for 89 patients. There was a statistically significant reduction in
quantitative rotatory knee laxity between preoperatively (inertial sensor,
2.55 ± 4.00 m/s2; image analysis, 2.04 ± 2.02 mm) and
postoperatively (inertial sensor, –0.54 ± 1.25 m/s2; image
analysis, –0.10 ± 1.04 mm) between the involved and healthy joints, as
measured by the 2 devices (P < .001 for both).
Postoperatively, both devices detected a lower rotatory laxity value in the
involved joint compared with the healthy joint (inertial sensor, 2.45 ± 0.89
vs 2.99 ± 1.10 m/s2, respectively [P < .001];
image analysis, 0.99 ± 0.83 vs 1.09 ± 0.92 mm, respectively
[P = .38]). Conclusion: The data from this study indicated a significant reduction in the pivot shift
when compared side to side. Both the inertial sensor and image analysis used
for the quantitative assessment of the pivot-shift test could successfully
detect restoration of the pivot shift after anatomic single-bundle ACL
reconstruction. Future research will examine how pivot-shift control is
maintained over time and correlation of the pivot shift with return to full
activity in patients with an ACL injury.
