Summary: Comparing the clinical outcomes of arthroscopic ACL repair and autograft ACL reconstruction for proximal ACL ruptures, this study found that both procedures had similar rates of failure, complications, reoperation, functional scores, and satisfaction. However, ACL repair had a higher rate of hardware removal and might be associated with greater knee laxity.

Summary: Patients undergoing revision ACL reconstruction did not show worse patient-reported outcomes, limb symmetry, strength, or functional performance compared with patients undergoing primary ACL reconstruction at 7 months postoperatively. However, patients who had revision ACL reconstruction exhibited inferior outcomes compared with the uninjured controls.

Summary: The study suggests that in ACL reconstruction surgery, preservation of residual but biomechanically insufficient ACL tissue may result in lower rates of clinical failures and revision surgeries at 1-year and 2-year follow-ups compared to standard ACL reconstruction without preserving residual ACL tissue.

Summary: The study found that skeletally immature female patients had a significantly higher prevalence of contralateral ACL injury compared to male patients, with a higher risk of contralateral injury. Therefore, postoperative rehabilitation, gradual activity progression, and return-to-play testing need to be improved to ensure a safe return to sports after ACL reconstruction.

Summary: The purpose of this study was to determine ACLR failure rates in a physically high-demand population and identify patient-specific risk factors. The factors that increased failure include Army service, > 180 days from injury to ACLR, tobacco use, and younger patient age.

Summary: ACL repair and ACL reconstruction appear to have comparable short-term outcomes. The low revision rate after primary repair is encouraging. For patients with ACL injury, current repair techniques such as dynamic intraligamentary stabilization and bridge-enhanced ACL repair may be an effective alternative to reconstruction.

Summary: Lateral extra-articular tenodesis (LET) reduces the risk of ACL graft rerupture in high-risk patients. Ilio-tibial band (ITB)-related LET is believed to effectively restrain anterolateral rotatory instability (ALRI) in ACL-injured and reconstructed knees. However, there is a potential for conflict between a modified Lemaire LET femoral tunnel and an ACL femoral tunnel, which may lead to iatrogenic ACL graft damage or compromised fixation.

Summary: This study assessed the rate of further ACL injury in patients who have undergone ACLR after soccer injuries in Australia. It found that younger age, male sex, and return to soccer were risk factors for further ACL injury. The study also concluded that ACLR with hamstring autograft allowed 70% of patients to return to soccer.

Summary: This study compared the risk of subsequent ipsilateral knee surgery in middle-aged patients after an ACL injury treated with initial conservative management (CM) versus ACL reconstruction (ACLR). The results showed that nonoperatively managed ACL tears in middle-aged patients were more common and occurred earlier in subsequent ipsilateral knee surgeries compared to reconstruction.

Summary: This study compared proprioception recovery after anterior cruciate ligament reconstruction (ACLR) with a hamstring tendon autograft versus the LARS artificial graft. The results showed that both groups had higher JPS error at 3 months after ACLR compared to 12 months. However, there was no significant difference in JPS error between the LARS and autograft groups at either 3 or 12 months after ACLR. Analyzing the data based on the timing of ACLR surgery showed a significant difference between groups at 3 months, but not at 12 months after ACLR. This suggests that both ACLR methods are similarly safe and effective for recovering knee proprioception.

Summary: Studies have shown a possible association between a steep posterior tibial slope and graft failure following anterior cruciate ligament reconstruction. However, this study did not find a direct correlation between the posterior tibial slope and the likelihood of revision ACL surgery.

Summary: This study longitudinally examined the quadriceps torque complexity in individuals who underwent ACL reconstruction after ACL injury. The results showed a decrease in quadriceps peak torque and an increase in torque complexity in the involved limb compared to the uninvolved limb. These findings suggest that ACL reconstruction not only leads to a decline in quadriceps strength, but also compromises the quality of quadriceps muscle contraction, which may contribute to impaired physical function in individuals following ACL reconstruction.

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: ACL tear is a common injury in sports and accidents, accounting for over 50% of all knee injuries. ACL reconstruction aims to restore knee stability, but biological graft healing after ACLR faces challenges in tendon graft-to-bone tunnel healing and graft mid-substance remodeling. Strategies that are osteoinductive, angiogenic, or anti-inflammatory may drive graft healing toward the ultimate targets of mineralization of tunnel graft and ligamentization of graft mid-substance.

Summary: The study found that intensive supervised rehabilitation following ACL reconstruction did not show superiority over less supervised rehabilitation in improving self-reported function and sports participation, indicating the need for more high-quality research to confirm the conclusions.
