For years, bioengineers and orthopaedic surgeons have applied the principles of mechanics to gain valuable information about the complex function of the anterior cruciate ligament (ACL). The results of these investigations have provided scientific data for surgeons to improve methods of ACL reconstruction and postoperative rehabilitation. This review paper will present specific examples of how ...

PURPOSE The purpose of our study was to systematically review current arthroscopic and related literature and to characterize the anatomic centrum of the anterior cruciate ligament (ACL) femoral footprint. METHODS On June 2, 2011, 2 independent reviewers performed a Medline search using the terms "anterior cruciate ligament" or "ACL," "femur" or "femoral," and "anatomy" or "origin" or "footpr...

Introduction: Single-bundle anterior cruciate ligament (ACL) reconstruction has been the standard option to treat ACL-deficient knees. However, biomechanical studies have shown that normal rotational laxity cannot be restored with single-bundle reconstructions [1]. Recently, anatomic reconstruction of the anteromedial (AM) and posterolateral (PL) bundles has been introduced [2]. However, it rem...

Although anterior cruciate ligament (ACL) reconstruction is considered a successful procedure in restoring knee stability, few studies have addressed the issue of aerobic capacity after ACL surgery. Soccer players need technical, tactical and physical skills to succeed, such as good knee function and aerobic capacity. Our purpose is to evaluate aerobic fitness in ACL injured professional footba...

Anterior cruciate ligament (ACL) injuries most commonly occur during sports that involve sudden stops and changes in direction, such as basketball, soccer, tennis, and volleyball. Depending on the severity of the ACL injury, treatment may include surgery to replace the torn ligament followed by rehabilitation exercises to help the patient regain strength and stability. However, controversy exis...

Anterior cruciate ligament reconstruction has evolved significantly since the early 1900's, back when an emphasis was placed on repair and not reconstruction. Over the past century, the technique has evolved from intra-articular non anatomic reconstruction, to extra articular reconstruction, back to intra articular (performed arthroscopically), to now, the advent of anatomic insertion site rest...

BACKGROUND Anterior cruciate ligament (ACL) reconstruction with hamstring autografts less than 8.5 mm in diameter is associated with worse patient-reported outcome scores and increased risk of revision surgery compared with reconstructions performed with larger grafts. One proposed solution to small autograft harvest is to create a hybrid graft by augmenting autografts with allograft tissue to ...

BACKGROUND Rupture of the anterior cruciate ligament (ACL) is a common sports injury and is known to be associated with an increased risk of knee osteoarthritis. Several studies have indicated that the risk of additional injuries to the menisci and articular cartilage increases with delays in the treatment of ACL tears. However, no consensus has been reached regarding the ideal timing for ACL r...

Background An anterior cruciate ligament (ACL) rupture is a frequent injury, with short and long-term consequences if left untreated. With a view to benefitting as many patients as possible and preventing future complications, we created a low-cost ligament reconstruction technique. Method The present article describes an anatomic ACL reconstruction technique. Results The technique involves...

BACKGROUND Anterior cruciate ligament (ACL) tears are one of the most common injuries among athletes. However, the ability to fully restore rotational stability with ACL reconstruction (ACLR) remains a challenge, as evidenced by the persistence of rotational instability in up to 25% of patients after surgery. Advocacy for reconstruction of the anterolateral ligament (ALL) is rapidly increasing ...
