Summary: The study found that an hourglass-shaped graft was more effective in restoring knee stability and graft force at a knee flexion angle of 30 degrees compared to columnar grafts, while also reducing the risk of notch impingement.

Summary: The aim of this study was to evaluate the risk of osteoarthritis (OA) in the medium-term follow-up of combined anterior cruciate ligament (ACL) reconstruction (ACLR) and anterolateral ligament reconstruction (ALLR) compared to isolated ACLR. The results showed no difference in joint space narrowing in the lateral tibiofemoral and patellofemoral compartments between the two groups, but the risk of medial patellofemoral joint space narrowing was higher in the isolated ACLR group.

Summary: ACL repair with dynamic intraligamentary stabilization (DIS) shows comparable knee joint stability and patient-reported outcomes (PROs) to ACL reconstruction at 5 years postoperatively in patients with acute isolated ACL tears. However, the rates of recurrent instability and revision surgery need further evaluation.

Summary: The study demonstrated that knee laxity and functional knee outcome after contralateral ACL reconstruction are comparable to those after primary ACL reconstruction. It is important for clinicians to inform patients about their expectations after contralateral ACL reconstruction. This study indicates that outcomes after contralateral ACL reconstruction in terms of knee laxity and functional knee outcome are predictable and likely to be comparable to those after primary ACL reconstruction.

Summary: This meta-analysis evaluated the outcomes of complete transphyseal (CTP), partial transphyseal (PTP), and physeal-sparing (PS) techniques for anterior cruciate ligament (ACL) reconstruction. The results showed that the PS technique had better knee laxity restoration compared to the PTP and CTP approaches, but there were no significant differences in subjective and objective scores. There was no clear superiority of one technique over the others in terms of retears, growth disturbances, and axial deviations.

Summary: ACL reconstruction surgery appears to trigger a second inflammatory response and an increase in markers for cartilage degradation. This suggests that post-operative chondroprotection may be necessary to prevent further damage to the cartilage.

Summary: This study aimed to compare the differences in functional performance between patients 2 years after ACL-IB and ACL-R surgeries. The results showed that the functional performance was comparable between ACL-IB and ACL-R for a specific subgroup of patients, but both patient groups exhibited leg asymmetry and compromised single-leg hop performance.

Summary: This study systematically reviewed previous reviews and found that ACL injury and surgical treatment significantly increase the risk and prevalence of knee OA. Furthermore, surgical treatment does not reduce the prevalence of OA in the long term compared to nonsurgical treatment.

Summary: This study aimed to analyze the tibiofemoral bone bruise patterns in multiligament knee injuries (MLKIs) and specifically their association with common peroneal nerve (CPN) injuries. The study found a strong association between grade 3 posterolateral corner (PLC) injuries and CPN injuries. Additionally, the presence of anteromedial femoral condyle bone bruising on MRI was significantly correlated with CPN injuries on physical examination.

Summary: The literature provides mixed evidence on the protective capacity of head and neck characteristics against mTBI. Some studies found associations between head-neck strength and size variables and protection against mTBI incidence and reduced impact kinematics, while others did not. Interestingly, two studies found that stronger and larger athletes were more at risk of sustaining high impacts. Strength and size metrics may have some predictive power, but impact mitigation is influenced by various factors. Due to heterogeneity in study design and reporting, a meta-analysis could not be performed.

Summary: This study investigated the relationship between functional and isokinetic testing at 6 months following primary ACL reconstruction (ACLR) as risk factors for second anterior cruciate ligament (SACL) injuries. The results indicated that patients with certain elevated isokinetic scores in the injured limb at 6 months after ACLR had a higher rate of subsequent ACL injuries than those who had lower peak torque.

Summary: This study examined changes in trunk, hip, and knee kinematics in maturing male athletes during an unanticipated cutting task. The results showed that as the boys matured, there was a decrease in hip flexion and angle at initial contact, and an increase in trunk contralateral rotation. Maturing athletes adopted a more erect cutting strategy, which is associated with greater knee joint loading.

Summary: The study aimed to determine whether clinical measures of hop performance and thigh muscle strength could predict total limb work in young athletes after ACL repair. The results showed that both hop test performance and thigh muscle strength were associated with total work during a single-leg jump test. Quadriceps femoris peak torque at 180O/s was the strongest predictor of total work.

Summary: A study retrospectively evaluated preoperative MRI scans of patients with acute grade 3 combined PLC injuries and found that ramp lesions were present in 26.5% of these patients. Additionally, the study determined that preoperative PMTP bone bruising was significantly associated with the presence of ramp lesions on MRI. These findings highlight the importance of assessing potential ramp lesions during multiligament reconstruction.

Summary: Existing RTP assessments are not effective in reducing the risk of subsequent ACL injury after ACL reconstruction. These standardized criteria do not replicate the physical and cognitive demands of sports. Algorithms like the 5 factor maximum model can help identify at-risk individuals, but they lack specificity to soccer players. Including ecological situations specific to soccer players in RTP evaluations is crucial for assessing players in conditions closest to their sporting activity, particularly with high cognitive load. Various clinical and field tests should be performed to assess strength, psychological variables, and neuromotor control in standard and ecological situations. Further scientific research is needed to validate this approach.

Summary: This study investigated the mechanical behavior of healthy human Achilles tendons during failure using digital image correlation. The results showed that the strength of the tendons was higher than previously reported, and the weakest part of the tendon showed high longitudinal strains just before rupture. These findings provide new insights into the mechanical behavior of tendons during stretching to failure.
