BACKGROUND: Revision anterior cruciate ligament reconstruction (ACLR) is becoming increasingly common as the number of primary ACLR cases continues to rise. Despite this, there are limited data on the outcomes of revision ACLR and even less information specifically addressing the differences in 1-stage revision reconstruction versus those performed in a 2-stage fashion after primary reconstruction. PURPOSE: To compare the outcomes, patient satisfaction, and failure rates of 1-stage versus 2-stage revision ACLR...

BACKGROUND: Second anterior cruciate ligament (ACL) tears after reconstruction occur at a reported rate of 20% to 30%. This high frequency indicates that there may be factors that predispose an athlete to graft failure and ACL tears of the contralateral knee. PURPOSE: To determine the incidence of second ACL injuries in a geographic population-based cohort over a 10-year observation period. STUDY DESIGN: Descriptive epidemiological study. METHODS: International Classification of Diseases, 9th Revision (ICD-9) codes relevant to the diagnosis of an ACL tear and the procedure code for ACL reconstruction were searched across the Rochester Epidemiology Project, a multidisciplinary county database, between the years of 1990 and 2000...

BACKGROUND: Younger patients and those with smaller hamstring autograft diameters have been shown to be at significantly greater risk of graft failure after anterior cruciate ligament (ACL) reconstruction. To date, there is no information in the literature about the clinical success and/or cost-effectiveness of increasing graft diameter by augmenting with semitendinosus allograft tissue for younger patients. HYPOTHESIS: Hybrid hamstring grafts are a cost-effective treatment option because of a reduced rate of graft failure...

BACKGROUND: The use of allograft tissue for anterior cruciate ligament reconstruction (ACLR) remains controversial. PURPOSE: To compare the risk of aseptic revision between bone-patellar tendon-bone (BPTB) autografts and BPTB allografts. STUDY DESIGN: Cohort study; Level of evidence, 2. METHODS: A retrospective cohort study of prospectively collected data was conducted using the Kaiser Permanente ACLR Registry. A cohort of patients who underwent primary unilateral ACLR with BPTB autografts and BPTB allografts was identified...

BACKGROUND: Many long-term studies have looked at outcomes after anterior cruciate ligament reconstruction (ACLR), but none have correlated long-term outcomes with postoperative laxity greater than 5 mm. It has been stated previously that more than 5 mm of postoperative graft laxity constituted a procedural failure. PURPOSE: To directly compare tight grafts (<3 mm) and loose grafts (>5 mm) to determine the effect of graft laxity, as measured by KT-1000 arthrometer, after ACLR on long-term clinical outcomes...

BACKGROUND: The quadriceps tendon (QT) autograft is known as an effective graft for anterior cruciate ligament (ACL) reconstruction and shows a similar functional outcome to the bone-patellar tendon-bone (BPTB) in randomized controlled trials, with a lesser incidence of complications. Up until now, only 2 studies have compared QT to hamstring tendon (HT) autograft. HYPOTHESIS: The functional outcomes of the QT technique are at least as good as those of the HT technique, with the same morbidity...

PURPOSE: Hamstring graft fixation on the patellar side during medial patellofemoral ligament (MPFL) reconstruction is usually with transosseous tunnels and can frequently lead to further problems. The aim of our study was to compare and analyse patellar complications in single patellar tunnel versus double tunnel hamstring graft fixation. METHODS: Twenty-nine knees with MPFL reconstructions (group S) in which the hamstring tendon graft was transfixed using a suspensory fixation method in a single tunnel drilled across the patella were analysed in comparison with 29 knees (group D) with interference fixation of the graft through two tunnels drilled up to a predetermined depth in the patella...

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: Hypoplasia or congenital absence of the anterior cruciate ligament (ACL) is a rare disorder occurring in ∼1 in every 6000 births. Although some patients with hypoplasia or agenesis of the ACL may not complain of instability, others desire to participate in more demanding activities that require the stability of a competent ACL. There are limited reports of surgical treatment of this patient population. The purpose of this study was to report ACL reconstruction in a case series of patients with symptomatic congenital ACL deficiency...

INTRODUCTION: Latest advances made in joint replacement implants allows reconstruction of entire limbs. These special prostheses or megaprostheses were originally designed for the treatment of severe oncological bone loss. Nowadays, however, the indications and applications of these devices are expanding to other orthopaedic and trauma clinical conditions. Since 2008 we have implanted 152 megaprostheses in non-oncological conditions: 87 were implanted for post-traumatic failures aseptic/septic (represented by complex non-unions and critical size bone defects); 26 total femur, 52 distal femur and 9 proximal tibia...

EDITORIAL
Frank R Noyes
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...

BACKGROUND: We describe the preliminary clinical results of a patellar stabilization technique to treat bidirectional patellar subluxation (BPS). METHODS: Patients: six patients (one male, five females; mean age 30.2years) underwent this procedure with a minimum of 24months follow-up. Patients were assessed for clinical instability, patellar complications, and need for revision surgery. Patient functional outcomes were evaluated using the criteria of Crosby and Insall and the Kujala Anterior Knee Pain Scale at the time of final follow-up...

INTRODUCTION: The use of the semitendinosus tendon alone for anterior cruciate ligament reconstruction keeps the gracilis muscle intact and decreases anterior pain in comparison with the use of the patellar tendon. Recently, Lubowitz described a new all-inside technique with an ST4 tendon fixed with a cortical button in both femoral and tibial sides. We hypothesized that this type of graft with cortical button fixation provides well-controlled residual anterior tibial translation (<3mm)...

Anterior cruciate ligament (ACL) reconstructive surgeries, employing a total of 48 models, were conducted by virtually removing the ACL and then modeling the surgical preparation, tunnel architecture, graft pre-tensioning and fixation angle of a bone-patellar-tendon-bone autograft. Multifactorial sensitivity analyses were performed to assess the relative influence of these surgical factors on the intraoperative joint laxity, graft-tunnel contact mechanics and graft forces. The sensitivity results indicated that the combined variation in tunnel architecture and graft pre-tension at the time of fixation accounts for most of the estimated variance of the three outcomes...

BACKGROUND: The administration of nonsteroidal anti-inflammatory drugs (NSAIDs) to patients undergoing anterior cruciate ligament reconstruction (ACLR) is controversial because it may impair tissue healing and clinical outcomes. PURPOSE: To assess the effect of NSAID administration on patients undergoing ACLR. STUDY DESIGN: Cohort study; Level of evidence, 3. METHODS: Included patients were aged >15 years and were registered in the Norwegian Knee Ligament Registry from 2008 until 2013 after the primary ACLR...

BACKGROUND: The surgical technique for anterior cruciate ligament (ACL) reconstruction has evolved as a result of improved understanding of ligament biomechanics, anatomy, device development, and failed reconstructions. Studies on surgical technique preferences have been limited to surgeon surveys, which are subject to selection and recall bias. The purpose of this study was to evaluate ACL reconstruction surgical technique and yearly revision rate trends in a community-based setting...

With the increasing incidence of anterior cruciate ligament (ACL) reconstruction in women and younger patients, the optimal graft choice in the young female patient has become the subject of much debate. This study aimed to evaluate patient-reported outcomes, objective knee stability, complication rates, and the incidence of failure after ACL reconstruction using bone-patellar tendon-bone (BPTB) autograft compared with hamstring (HS) autograft in young female patients. Female patients who underwent primary ACL reconstruction with BPTB or HS autograft between ages 15 and 25 years were identified...
