Introduction: Anterior Cruciate Ligament (ACL) injuries are a major concern in orthopedics, particularly affecting active individuals and often necessitating surgery. The incidence of ACL injuries is rising, especially in women, comprising half of knee joint injuries. These injuries, common in sports with pivoting actions, can lead to long-term joint issues like osteoarthritis. Advances in surgical methods and understanding of postoperative recovery are crucial for improving patient outcomes, with considerations for graft size, material, and reconstruction technique critical in the rehabilitation process. Material and Methods: A systematic review was conducted by searching PubMed, MEDLINE, and SCOPUS for studies from 2009 to 10 February 2024, focusing on “six-strand hamstring graft” outcomes in ACL reconstruction. Inclusion criteria were English publications on 6HS autografts’ biomechanical and clinical outcomes. Excluded were non-specific, BTB, or hybrid studies, and non-research articles. Out of 347 records, 9 were analyzed after rigorous screening and quality assessment. This review, emphasizing six-strand hamstring autografts, enriches orthopedic knowledge, particularly for ACL surgery. Results: This review evaluated studies on six-strand hamstring (6HS) autografts for ACL reconstruction, encompassing prospective, retrospective, and cadaveric studies with subjects ranging from 12 to 413. Findings indicate that 6HS autografts enhance knee stability and increase graft diameter, correlating with reduced graft failure rates and improved clinical outcomes, including high patient satisfaction and low re-injury rates. Rehabilitation varied, with recovery times quicker due to larger graft sizes, and most studies reported low complication rates, underscoring 6HS autografts’ efficacy in ACL surgery. Conclusions: Performing 6HS autografts in ACL reconstruction reveals that they offer improved knee stability and graft diameter, leading to better clinical outcomes. These autografts are associated with high patient satisfaction and low re-injury rates, suggesting their effectiveness in mimicking native ACL function and enhancing rehabilitation. However, research limitations highlight the need for further long-term, comprehensive studies. |
