In a select group of patients with proximal anterior cruciate ligament (ACL) tears, primary repair can be a useful technique. Preservation of the native ACL may be advantageous for proprioceptive function and is thought to restore normal knee joint kinematics. The procedure is a less morbid and more conservative surgical approach to restore knee stability. Primary repair is preferably performed in the acute setting because of better healing capacity and tissue quality. We present the surgical technique of arthroscopic primary ACL repair with suture anchors in patients with proximal tears and excellent tissue quality...

BACKGROUND: Many strategies have been used to improve the visualisation of the ACL including sagittal, coronal oblique sequences, and 3D volume imaging. Nevertheless, the ACL may not always be visualised. METHODS: Two hundred and thirty-one consecutive patients (77 females; 154 males; average age 43.5, range 18 to 82 years; 205 with chronic, 20 acute, and 6 acute on chronic symptoms) underwent knee arthroscopy for mechanical symptoms within a week of MRI. After routine orthogonal sequences, if general MRI radiographers, with over four years experience, were not able to identify the presence of the ACL, then two 3D volume sequences and 2D limited sagittal oblique T1 sequences were performed...

BACKGROUND: Hip arthroscopy for femoroacetabular impingement (FAI) is known to produce excellent outcomes, yet some patients do not return to their preinjury level of sport participation. Much literature on return to sport has revolved around anterior cruciate ligament reconstruction and even shoulder instability, but none to date have used qualitative, semistructured patient interviews on patients with hip labral tears. PURPOSE: To understand the factors influencing the decision to return to sport after arthroscopic hip surgery for FAI...

This article aims to evaluate factors associated with chondral and meniscal lesions in primary and revision anterior cruciate ligament (ACL) reconstructions. ACL reconstructions from 2001 to 2008 at a single institution were retrospectively analyzed. Logistic regression was used to estimate the association between chondral and meniscal injuries and age, gender, tear chronicity, additional ligamentous injuries, sport type, and participation level. Of the 3,040 ACL reconstructions analyzed, 90.4% were primary reconstructions and 9...

BACKGROUND: Magnetic Resonance Imaging is an appropriate screening tool before therapeutic arthroscopy, making diagnostic arthroscopy unnecessary in most patients. This study aims to evaluate the MRI findings in knee injuries and diagnostic value of low Strength MRI for assessing Meniscal and cruciate ligament tear. METHODS: A cross sectional study was conducted on patients undergoing "Magnetic Resonance Imaging of the Knee" for injuries of the knee and excluded patients undergoing MRI for other causes, poor diagnostic quality MRI and post operative MRI...

BACKGROUND: Conduct a prospective randomized study to compare clinical outcomes of anterior cruciate ligament (ACL) reconstruction using quadrupled hamstring tendon (HT) allograft or doubled tibialis anterior (TA) allograft. Limited level 1 data exist comparing outcomes of different soft tissue allograft constructs for ACL reconstruction. We hypothesized no difference would exist in the patient reported outcomes (PRO), arthrometric testing, or rate of re-rupture between the two constructs...

REVIEW
Christian N Anderson, Allen F Anderson
Intrasubstance tears of the anterior cruciate ligament (ACL) are being diagnosed with increasing frequency in the skeletally immature. Management options include nonoperative/ early surgical, or delayed surgical reconstruction. Nonoperative/delayed reconstruction results in worse functional outcomes than early reconstruction. Physicians are faced with a treatment dilemma; clinical and basic science studies have demonstrated risk of limb-length discrepancy and angular deformity with ACL reconstruction. Vertical drill tunnels decrease physeal damage and minimize growth deformity; however, this technique results in nonanatomic ACL graft placement...

REVIEW
Nicholas I Kennedy, Christopher M LaPrade, Robert F LaPrade
Posterolateral knee injuries occur more commonly than in the past. These injuries most commonly occur concurrent with cruciate ligament tears. The main stabilizers of the posterolateral knee are the fibular collateral ligament, the popliteus tendon, and the popliteofibular ligament. These static stabilizers function to prevent increased varus, external rotation, and coupled posterolateral rotation of the knee. The most important clinical tests to diagnose posterolateral knee injuries are the varus stress test, posterolateral drawer, and dial tests...

PURPOSE OF REVIEW: As anterior cruciate ligament (ACL) injury is becoming increasingly prevalent in the population of active children and young adolescents, it is crucial to be aware of both the modifiable and nonmodifiable factors that place this population at increased ACL injury risk. Historically, there has not been a definitive consensus on all of these risk factors-particularly the nonmodifiable ones. RECENT FINDINGS: The present review has accumulated the most recent evidence for the nonmodifiable risk factors in ACL injury focusing particularly on female gender, generalized joint laxity, knee recurvatum, increased lateral tibial slope, decreased intercondylar notch width, structural lower extremity valgus, limb length discrepancy, family history, and history of contralateral knee ACL injury...

OBJECTIVE: Anterior cruciate ligament (ACL) tears are common injuries in adolescent athletes, especially in those who bear high stress on their knees due to shearing forces. The goal of the surgical procedures in skeletally immature patients is to restore joint stability avoiding the adverse effects on the growth process. The aim of this study was to verify the return of the skeletally immature professional athletes to sports in the long-term, following ACL reconstruction with the original all-inside technique and with manual drilling...

BACKGROUND: Anterior cruciate ligament (ACL) tears in children are increasingly common and present difficult treatment decisions due to the risk of growth disturbance. Although open primary ACL repair was abandoned in the historical literature, recent studies have suggested that there is a role for arthroscopic primary repair in patients with proximal tears. METHODS: This is a retrospective review of five consecutive patients aged 9.2years (range 8 to 10) who underwent suture anchor ACL reinsertion...

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 reconstruction in terms of preventing secondary lesions. PURPOSE: To determine how the time elapsed between an ACL lesion and its reconstruction affects the incidence of meniscal and chondral lesions...

BACKGROUND: The time between an anterior cruciate ligament (ACL) injury and ACL reconstruction (ACLR) may influence baseline knee-related and general health-related patient-reported outcome measures (PROMs). Despite the common use of PROMs as main outcomes in clinical studies, this variable has never been evaluated. PURPOSE: To compare baseline health-related quality of life measures and the prevalence/pattern of meniscal and articular cartilage lesions between patients who underwent acute and chronic ACLR so as to provide clinicians with benchmark PROMs in 2 different patient populations with ACL injuries...

BACKGROUND: Dynamic augmentation of anterior cruciate ligament tears seems to reduce anteroposterior knee translation close to the pre-injury level. The aim of the present study is to biomechanically investigate the course of translation during a simulated early post-operative phase. It is hypothesized that anteroposterior translation is maintained at the immediate post-operative level over a simulated rehabilitation period of 50'000 gait cycles. METHODS: Eight fresh-frozen human cadaveric knee joints from donors with a mean age of 35...

BACKGROUND: Reduced quadriceps strength influences knee function and increases the risk of knee osteoarthritis. Thus, it is of significant clinical relevance to precisely quantify strength deficits in patients with knee injuries. PURPOSE: To evaluate isokinetic concentric quadriceps muscle strength torque values, assessed both from peak torque and at specific knee flexion joint angles, in patients with anterior cruciate ligament (ACL) injury, focal cartilage lesions, and degenerative meniscus tears...

BACKGROUND: Generalized joint laxity has been linked to ligamentous injuries such as anterior cruciate ligament tear and ankle sprain. PURPOSE/HYPOTHESIS: The purpose of this study was to investigate generalized joint laxity and incidence of ligament injuries in high school-aged female volleyball players. It was hypothesized that volleyball players with a past history of sprains would have increased generalized joint laxity compared with those without any history and that athletes with multiple sprains would demonstrate with a higher generalized joint laxity score than those who had only 1 sprain...

Football has the highest injury rate amongst popular American sports. Of those injuries that end seasons or careers, the knee is the most common culprit. This is of particular concern because knee injuries are most common in football. This article reviews 4 of the most common knee injuries in American football, with emphasis on epidemiology, risk factors, and treatment outcomes. The injuries reviewed are tears of the anterior cruciate ligament, medial collateral ligament, medial patellofemoral ligament, and posterior cruciate ligament...

BACKGROUND: The anterolateral meniscal root (ALMR) has been reported to intricately insert underneath the tibial insertion of the anterior cruciate ligament (ACL). Previous studies have begun to evaluate the relationship between the insertion areas and the risk of iatrogenic injuries; however, the overlap of the insertions has yet to be quantified in the sagittal and coronal planes. PURPOSE: To investigate the insertions of the human tibial ACL and ALMR using scanning electron microscopy (SEM) and to quantify the overlap of the ALMR insertion in the coronal and sagittal planes...

Reverse Segond fracture is originally described as an indirect radiographic clue for a specific injury complex of the knee joint that includes posterior cruciate ligament (PCL) rupture and medial meniscal tear. Herein, we describe a case with reverse Segond fracture associated with PCL avulsion fracture instead of PCL rupture. According to current literature review, reverse Segond fracture is not only associated with PCL and medial meniscal injuries, but also frequently associated with anterior cruciate ligament (ACL) and medial collateral ligament (MCL) injuries...
