There remains controversy on the role of a concurrent lateral extra-articular procedure with anterior cruciate ligament (ACL) reconstruction. Previous biomechanical studies often are historical and inconclusive. Studies show the anterolateral ligament and iliotibial band are secondary restraints and, when injured in conjunction with the ACL, produce gross (Grade 3) pivot-shift subluxations. Recent robotic studies show a well-placed bone-patellar tendon-bone reconstruction does restore time-zero kinematics with a negative pivot-shift...

Anterior cruciate ligament (ACL) injuries are common and affect a young, active patient population. Despite much research, ACL reconstruction graft choice remains a topic of debate. Based on the best available evidence, autograft seems to be superior to allograft for ACL reconstruction in young, active patients. Future high-level studies are required in order to better define the role of allograft in ACL reconstruction. As graft choice is often influenced by surgeon preference, it is important that surgeons understand the current literature as well as the goals of their patients...

BACKGROUND: Despite the importance of hamstring tendon autograft, one major disadvantage in applying this technique in the surgical reconstruction of anterior cruciate ligament is individual variability in the tendon diameter. Hence, the purpose of the present study was to use anthropometric parameters such as gender, height and body mass index to predict 4-strand (quadruple) hamstring tendons (gracilis and 2-strand semitendinosus tendons). METHODS: This is a cross-sectional study conducted on all consecutive patients who underwent arthroscopic ACL reconstruction between 2013 and 2015...

When considering the femoral attachment location for an anterolateral ligament reconstruction, the femoral attachment site should be positioned proximally and posteriorly to the lateral epicondyle to restore the physiologic length change of the native ligament. However, the clinical significance of the anterolateral ligament in patients having anterior cruciate ligament reconstructive surgery remains controversial.

Since 2015, the Multicenter Orthopedic Outcomes Network (MOON) has addressed several factors associated with patient outcome after anterior cruciate ligament (ACL) injury. These factors include predictors of high grade knee laxity, the impact of meniscus treatment on joint space narrowing after surgery, graft selection, treating diabetic patients, predictors of clinically significant pain, and outcomes of patients where meniscus tears were left in situ without treatment. The presence of meniscus tears and generalized laxity predict a lax examination under anesthesia prior to surgery...

PURPOSE: The growing popularity of elite soccer among female participants has led to increased incidents of anterior cruciate ligament (ACL) ruptures. Many authors underline a positive glide after ACL reconstruction (ACLR), especially in women. In fact, an isolated intra-articular ACLR may be inadequate to control rotational instability after a combined injury of the ACL and the peripheral structures of the knee. Extra-articular procedures are sometimes used in primary cases displaying excessive antero-lateral rotatory instability...

BACKGROUND: Anterior cruciate ligament (ACL) tears are frequently treated with surgical reconstruction with grafts, frequently patella tendon or hamstrings. Interference screws are often used to secure the graft in bone tunnels in the femur and tibia. This review examines whether bioabsorbable interference screws give better results than metal interference screws when used for graft fixation in ACL reconstruction. OBJECTIVES: To assess the effects (benefits and harms) of bioabsorbable versus metallic interference screws for graft fixation in ACL reconstruction...

CONTEXT: Distinct exercises have been proposed for knee rehabilitation after anterior cruciate ligament (ACL) reconstruction. There is a need to understand ACL strain behavior during different rehabilitation exercises to protect the graft from excessive strain that could interfere with its healing process. OBJECTIVE: To critically review studies that directly measured normal ACL strain in vivo during different movements, conditions, or exercises to gain insight into which of them may produce more strain on the ligament or the ligament graft in the case of reconstructed knees...

REVIEW
Benjamin V Herman, J Robert Giffin
High tibial osteotomy (HTO) has traditionally been used to treat varus gonarthrosis in younger, active patients. Varus malalignment increases the risk of progression of medial compartment osteoarthritis and an HTO can be performed to realign the mechanical axis of the lower limb towards the lateral compartment, thereby decreasing contact pressures in the medial compartment. Anterior cruciate ligament (ACL) insufficiency may lead to post-traumatic arthritis due to altered joint loading and associated injuries to the menisci and articular cartilage...

In the present study, we combined stem cell technology with a non-absorbable biomaterial for the reconstruction of the ruptured ACL. Towards this purpose, multipotential stromal cells derived either from subcutaneous human adipose tissue (hAT-MSCs) or from induced pluripotent stem cells (iPSCs) generated from human foreskin fibroblasts (hiPSC-MSCs) were cultured on the biomaterial for 21days in vitro to generate a 3D bioartifical ACL graft. Stem cell differentiation towards bone and ligament at the ends and central part of the biomaterial was selectively induced using either BMP-2/FGF-2 or TGF-β/FGF-2 combinations, respectively...

BACKGROUND: Considerable debate remains over which anterior cruciate ligament (ACL) reconstruction technique can best restore knee stability. Traditionally, femoral tunnel drilling has been done through a previously drilled tibial tunnel; however, potential nonanatomic tunnel placement can produce a vertical graft, which although it would restore sagittal stability, it would not control rotational stability. To address this, some suggest that the femoral tunnel be created independently of the tibial tunnel through the use of an anteromedial (AM) portal, but whether this results in a more anatomic footprint or in stability comparable to that of the intact contralateral knee still remains controversial...

BACKGROUND: Rupture of the anterior cruciate ligament (ACL) is a common injury, mainly affecting young, physically active individuals. The injury is characterised by joint instability, leading to decreased activity, which can lead to poor knee-related quality of life. It is also associated with increased risk of secondary osteoarthritis of the knee. It is unclear whether stabilising the knee surgically via ACL reconstruction produces a better overall outcome than non-surgical (conservative) treatment...
