Summary: This study found that ACL graft slackening and an instrumented Lachman test with an increase in ATT of 3 mm or less were 100% predictive of a negative pivot-shift subluxation finding. Instrumented Lachman tests provide objective data on ACL function and graft failure, which are highly recommended for ACL studies.

Summary: The study found that combined double-bundle ACL reconstruction with ALS augmentation can improve knee rotational kinematics and provide better restoration of knee kinematics, but it may result in anterolateral rotatory overconstraint during lunge motion.

Summary: The study investigated the 3D topographic anatomy of ACL bundle attachment in both ACL-rupture and intact patients, identifying differences that may aid surgeons in performing double-bundle reconstruction surgery.

Summary: This study aimed to determine the mean values of tibial slope (TS) and the incidence of outliers on conventional lateral radiographs (CLRs) in large cohorts of patients with anterior cruciate ligament (ACL)-injured and noninjured knees. Results showed that the mean TS on CLR was 9 degrees for uninjured knees and 10 degrees for ACL-injured knees. Furthermore, a significantly larger number of outliers were found in the ACL-injured group, exceeding a TS of 12 degrees and demonstrating an incremental proportion with increasing TS, serving as a potential threshold for correction osteotomy. The study also confirmed the feasibility and reproducibility of using CLRs as a routine measurement for TS.

Summary: This study found that untreated LMORT tears increased anterior translation, pivot shift, and meniscal extrusion after ACL reconstruction, while partial meniscectomy further exacerbated these detrimental effects. In contrast, arthroscopic side-to-side repair of LMORT lesions effectively restored measured knee kinematics.

Summary: Recent research found that injured anterolateral ligaments (ALL) after ACL reconstruction have limited healing potential, with only 30.3% showing full healing by 12 months post-operation. The healing process took over 6 months in more than half of the patients. No significant risk factors for failure of full healing were identified in this study.

Summary: This study presents the protocol and preliminary results of a multi-vendor, multi-site quantitative MRI study for knee post-traumatic osteoarthritis (PTOA) 10 years after anterior cruciate ligament reconstruction (ACLR). The results indicate significant cartilage degeneration in both operated and contralateral knees compared with healthy control knees.

Summary: In a cohort study of 50 children undergoing ACL reconstruction, 28% were found to have ramp lesions, with MRI showing low sensitivity for diagnosing such lesions. Careful exploration of the posteromedial compartment during ACL reconstruction is recommended to prevent ongoing instability and higher re-rupture rates in young patients.

Summary: The study investigated the relationship between the coronal LCL sign and knee laxity measurements, finding that the LCL sign on MRI was not associated with clinical knee laxity evaluations, regardless of age groups.

Summary: Bone contusions commonly occur in noncontact ACL-injured knees as observed on early MRI scans. The most common patterns observed were four locations (LTP/LFC/MTP/MFC) and three locations (LTP/LFC/MTP) among the patients studied.

Summary: A classification system for bone bruise patterns was established to estimate the severity of knee injuries in pediatric patients with ACL tears. The system identifies the depth and location of bone bruises and predicts associated lesions, providing important information for preoperative evaluation.

Summary: This study assessed the kinematic alterations of the patellofemoral joint in anterior cruciate ligament deficiency (ACLD) knees with different types of meniscal tears during a single-leg lunge. The results showed that meniscal tears alter the patellofemoral joint kinematics in ACLD patients, and the type of meniscal tear also affects the kinematics.

Summary: The study aimed to investigate the effect of posterior tibial slope (PTS) on knee alignment. It was found that PTS was negatively correlated with knee extension angle (EXT) and positively correlated with tibial shaft anterior tilt to the vertical axis (TAT). Patients with ACL injury had larger EXT and smaller TAT.

Summary: The study aimed to develop a tool for classifying the severity of structural tissue damage in ACL injured knees. The ACL Injury Severity Scale (ACLISS) provides a simple description and categorization of a wide range of injuries in patients undergoing primary ACL reconstruction. The scale allows for the identification of different injury severity profiles.

Summary: This cadaveric study aimed to investigate the impact of anterolateral ligament (ALL) and anterolateral capsule (ALC) injuries on knee laxity with preserved iliotibial band (ITB) in anterior cruciate ligament (ACL)-injured knees. The results showed that injuries to ALL and ALC had a synergistic effect on knee laxity in terms of internal rotation, anterior translation, and varus angulation in ACL-injured knees.
