Purpose: Evaluate the outcomes of ACL (Anterior Cruciate Ligament) reconstruction techniques that use a hamstring graft with a preserved tibial insertion and compare them to standard techniques.
Methods: A systematic literature review and meta-analysis was done of the PubMed, MEDLINE, Cochrane and Ovid databases to identify published clinical studies on ACL reconstruction in which a non-detached hamstring tendon (NDHT) was used as a graft and to compare them to studies in which a detached hamstring tendon (DHT) or other techniques were used. The eligible studies were analyzed for the knee laxity, Lachman test, pivot shift test, joint range of motion, anterior drawer, pain, re-tear, revision surgery, Lysholm score, Tegner score, ACL-RSI scale, KOOS, IKDC, SNQ and Howell scale.
Results: Twelve articles in which NDHT was used for ACL reconstruction were analyzed. There was no significant difference between NDHT and DHT in the Lachman > 1 (p = .07), pivot shift test > 1 (p = .40), re-tears (p = .62), pain (p = .85) and the Tegner score (p = .95). However, the outcomes were somewhat better with the NDHT technique for the Lachman (RR = 0.30; 95% CI 0.08-1.12), pivot shift test (RR = 0.50; 95% CI 0.10-2.49) and re-tears (RR = 0.66; 95% CI 0.13-3.42). The other criteria were not included in the meta-analysis because of lack of data or because specific outcome scores were used in each article.
Conclusion: NDHT techniques provide similar results to DHT for ACL reconstruction and tend to produce better stability and a lower re-tear rate.

Purpose: Using a thin semitendinosus tendon as an autograft is a risk factor for poor clinical outcomes after anterior cruciate ligament reconstruction. Preoperative evaluation of the cross-sectional area of the semitendinosus tendon using magnetic resonance imaging is useful. However, studies comparing the cross-sectional area of the semitendinosus tendon on magnetic resonance imaging and the collagen fibril diameter of the semitendinosus tendon are lacking.

Background: Nonanatomical anterior cruciate ligament (ACL) reconstruction occasionally induces ACL failure without an evident injury episode, necessitating revision surgery. Although the in vivo kinematics of ACL deficiency before primary ACL reconstruction are well documented, the kinematics of ACL failure after nonanatomical reconstruction remain unexplored. The aim of this study is to investigate ACL failure kinematics following nonanatomical reconstruction.

Objective: To provide clinicians with reliable recommendations for the selection of appropriate suturing techniques for surgical management of common musculoskeletal soft tissue injuries.
Methods: A systematic search of PubMed, Springer, Web Science, Vip Database, China National Knowledge, and Wanfang Data for in vitro biomechanical studies on suture techniques in the surgical treatment of musculoskeletal soft tissue injuries covering relevant studies from April 2009 to April 2024 was performed. A generalized classification was made based on the characteristics of the techniques, and recommendations for the selection of suture techniques were made according to the GRADE concept.
Outcomes of All-Inside Arthroscopic ACL Reconstruction with Lateral Extra-Articular Tenodesis (ACLR + LET).

Background: Anatomic single-bundle ACL reconstruction (ACLR) produces good results when the graft and tunnel are positioned in the anatomic footprint on the femoral and tibial insertion sites in a more oblique orientation. The of the knee and its biomechanical role in controlling rotational laxity, internal rotation, and pivot shift has led to adding adjunctive procedures like extra-articular augmentation and lateral extra-articular tenodesis (LET) to decrease rotational laxity. We prospectively analyzed young adults with rotational instability and generalized laxity undergoing an arthroscopic single bundle ACLR with an additional LET procedure.
