Summary: The study aimed to evaluate the kinematic effects of arthroscopic centralization on an irreparable lateral meniscal defect, and found that this method reduced knee laxity and improved rotational stability in a cadaveric model under laboratory conditions.

Summary: This study compared the accuracy of an automatic knee arthrometer (AKA) to the KT-2000 arthrometer in measuring knee laxity after ACL ruptures. The results showed that AKA had smaller variance in measurements and better consistency between examiners. Compared to KT-2000, AKA had a higher diagnostic value in determining knee laxity.

Summary: This study compares the effects of different femoral tunnel positions on knee stability after arthroscopic anterior cruciate ligament reconstruction (ACLR). The results suggest that the high anteromedial (HAM) position provides better control over anteroposterior and rotational laxity as well as subjective knee function, making it the preferred location for the femoral tunnel in ACLR.

Summary: This study identified age, body mass index, knee laxity, knee strength, and passive knee alignment as risk factors for non-contact ACL injuries. Among these factors, age, passive knee extension, and weak hamstring strength were associated with a higher risk, while passive knee valgus was specifically identified as a risk factor for women. These findings suggest that hamstring strengthening exercises could be beneficial in preventing ACL injuries in young male athletes or individuals with knee laxity.

Summary: The study aimed to objectively assess the rotational laxity after primary ACL rupture and rerupture after ACL reconstruction by instrumented measurement. Patients with ACL rerupture showed significantly higher internal rotation laxity compared to those with primary ACL rupture, with the extent of rotational laxity quantifiable by instrumented measurements. These findings provide valuable data for determining the need for anterolateral ligament reconstruction in ACL revision surgery.

Summary: This study aimed to determine the association between excessive anterior tibial subluxation (ATS) and high-grade knee laxity in patients with anterior cruciate ligament (ACL) deficiency, and to identify the predictive cutoff value of ATS for high-grade knee laxity. The study analyzed 226 patients who underwent ACL reconstruction and found a significant association between excessive ATS and high-grade knee laxity. The findings of this study have important implications for preoperative evaluation of knee instability and surgical decision-making.

Summary: This study aimed to identify potential factors for both femoral and tibial tunnel widening (TW) and investigate the effect of TW on postoperative outcomes after ACL reconstruction. The shallow position of the femoral tunnel was significantly correlated with femoral TW. Patients with femoral TW >= 3 mm exhibited inferior postoperative knee anterior stability.

Summary: Higher graft signal intensity in younger patients was significantly associated with residual laxity after ACLR, while this relationship was not significant in older patients. SIR can be utilized to predict the likelihood of residual laxity.

Summary: The current evidence supports the notion that concomitant ALL reconstruction alongside soft tissue graft ACL reconstruction can improve clinical outcomes by enhancing knee stability and reducing re-rupture rates.

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.

Summary: Delay in ACLR is associated with increased risk of cartilage and MM injuries, while reducing the risk of LM injury. To minimize meniscus loss and knee laxity, ACLR should ideally be performed within 6 months post-injury.

Summary: This study investigated the changes in microRNA expression profiles in knee synovial fluid of patients with osteoarthritis (OA) and anterior cruciate ligament (ACL) rupture. The results showed that specific microRNAs were expressed differently in OA and ACL tear samples. These findings may contribute to further research on the mechanisms and treatments of osteoarthritis and ACL rupture.

Summary: The outcome of ACL surgery is influenced by factors such as patient characteristics, underlying knee pathologies, and bony morphology. Personalizing ACL surgery by evaluating each patient's specific anatomy can improve outcomes and reduce failure rates. Further research and awareness of relevant bony parameters are key to enhancing the ability to prevent injury and increase diagnostic accuracy.

Summary: This study found that visual function defect, especially low visual fusion range, is a risk factor for knee anterior cruciate ligament (ACL) sports injury. Quick turn, sudden stop, and jump during sports activities are also major risk factors.
