BACKGROUND: Bone-patellar tendon-bone (bone-tendon-bone) and four-strand hamstring tendon grafts (hamstring) are the most commonly utilized autografts for primary anterior cruciate ligament (ACL) reconstruction. Existing clinical trials, registry studies, and meta-analyses offer conflicting opinions regarding the most favorable graft choice. QUESTIONS/PURPOSES: Which graft type for ACL reconstruction (bone-tendon-bone or hamstring) has a higher risk of (1) graft rupture and/or (2) graft laxity? METHODS: We performed a meta-analysis of randomized controlled trials (RCTs), prospective cohort studies, and high-quality national registry studies to compare the outcomes of primary ACL reconstruction with bone-tendon-bone autograft or hamstring autograft...

BACKGROUND: The anterolateral ligament (ALL) has been proposed as a primary restraint for knee rotational stability. However, the data remain inconclusive. The purpose of this study was to determine the effect of the ALL and the iliotibial band (ITB) on knee rotational stability. METHODS: A 6-degrees-of-freedom robotic simulator was used to test 14 fresh-frozen cadaveric knee specimens. There were 4 testing conditions: intact, anterior cruciate ligament (ACL)-sectioned, ACL and ALL or ITB-sectioned (determined at random), and ACL and both ALL and ITB-sectioned...

The number of patients undergoing revision surgery following failure of anterior cruciate ligament (ACL) reconstruction has increased over the recent past, following the overall increased number of primary ACL reconstruction performed. Failure of primary ACL reconstruction can be attributed to technical errors, biological failures, or new traumatic injuries. Technical errors include femoral and/or tibial tunnels malposition, untreated associated ligaments insufficiencies, uncorrected lower limb malalignment, and graft fixation failures...

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...
