Background: We investigated the clinical outcome of anterior cruciate ligament (ACL) reconstructions with allograft or autograft.
Methods: We retrospectively evaluated 82 patients who underwent arthroscopic ACL reconstruction with anterior tibial tendon (ATT) allograft (n = 52) or quadrupled hamstring tendon (QHT) autograft (n = 30). The patients were assessed using the IKDC (International Knee Documentation Committee) and Lysholm knee scores and functional (one leg hop) and laxity (pivot-shift, Lachman, anterior drawer) tests.
Results: The two groups were similar with respect to age and sex distribution, operated side, preoperative period and associated injuries (p > 0.05). Results were satisfactory in both groups, but there was no statistically significant difference between the groups with respect to IKDC and Lysholm scores, functionality and ligament laxity (p > 0.05). However, effusions were more frequent in the QHT group compared to the ATT group.
Conclusion: Our results suggest that differences in graft options for ACL reconstruction have no effect on the clinical outcome. Allografts with to-be-developed solutions to immune response may be a good alternative in ACL reconstruction.

Does the Addition of a Lateral Extra-articular Procedure to a Primary Anterior Cruciate Ligament Reconstruction Result in Superior Functional and Clinical Outcomes? A Systematic Review and Meta-analysis of Randomized Controlled Trials.
Am J Sports Med

Background: Current research focused on clinical outcomes suggests that lateral extra-articular procedures (LEAPs) can reduce rotational instability and graft failure rates in primary anterior cruciate ligament reconstructions (ACLRs). Limited studies have investigated the functional outcomes after LEAPs, including patient-reported outcome measures, sports participation, and physical performance.
Purpose: To conduct a systematic literature review and meta-analysis to determine whether the addition of a LEAP to an ACLR results in superior functional and clinical outcomes as compared with an isolated ACLR.
Purpose: Anterior tibial closing wedge osteotomy (ATCWO) has been shown to significantly reduce failure rates of revision anterior cruciate ligament (ACL) reconstructions in patients with a posterior tibial slope (PTS) ≥12°. Recent findings suggest a slight but significant reduction of the medial proximal tibial angle (MPTA) resulting in a varus knee where the sagittal osteotomy plane is based on a total of two guide wires defining the osteotomy wedge without respecting the frontal plane. We hypothesize that the placement of a total of four guide wires intraoperatively can reduce the influence on the MPTA.

Objective: Given the high burden and increasing prevalence of post-traumatic osteoarthritis (PTOA), identifying clinically beneficial strategies to prevent or delay its onset could improve the quality of life of those at high risk of developing the disease.
Methods: Preventing Injured Knees from OsteoArthritis: Severity Outcomes (PIKASO) is a multicenter blinded, parallel, two-arm randomized controlled trial of 512 individuals aged 18-45 years undergoing anterior cruciate ligament reconstruction (ACLR). This study is designed to evaluate the efficacy of a 12-month intervention of oral metformin vs.

Background: Understanding the factors associated with poor recovery over time after anterior cruciate ligament reconstruction (ACLR) helps clinicians identify patients who are at risk and targets for an intervention.
Purpose: To determine the factors associated with improvement in subjective knee function from 6 to 12 months after ACLR.
Study Design: Case-control study; Level of evidence, 3.
Evaluation of Thigh Muscle Strength in Adolescent Patients After Anterior Cruciate Ligament Reconstruction With Lateral Extra-articular Tenodesis or Anterolateral Ligament Reconstruction.
Orthop J Sports Med

Department of Kinesiology, University of Virginia, Charlottesville, Virginia, USA.
Background: There has been increased interest in lateral extra-articular procedures, such as anterolateral ligament reconstruction (ALLR) or lateral extra-articular tenodesis (LET), to reduce anterolateral rotation instability of the knee after anterior cruciate ligament reconstruction (ACLR). Despite promising surgical outcomes with these techniques, their impact on knee strength recovery is unknown.
Hypothesis: Patients undergoing lateral extra-articular procedures at the time of ACLR would have impaired thigh muscle strength at 6 to 9 months after surgery.
