PURPOSE: To identify patient-related risk factors for infection following anterior cruciate ligament reconstruction (ACLR). METHODS: The Mariner database within PearlDiver was queried for patients from 2010 to 2019 undergoing primary arthroscopic ACLR. Patients undergoing ACLR with concomitant open surgery or additional ligament reconstructions were excluded. Postoperative diagnoses or procedures for superficial or deep infection within 6 months were assessed. A multivariable logistic regression analysis was then used to evaluate patient-related risk factors for postoperative infection...

BACKGROUND: At present, the most effective and mature treatment after ACL injury and tear is ACL reconstruction, but the rehabilitation process after ACL reconstruction that is very long, so it is very important to find early MRI positive findings of knee instability. METHODS: We retrospectively collected the clinical and imaging data of 70 patients who underwent ACL reconstruction from January 2016 to December 2019; Based on clinical criteria, the patients were divided into a stable group (n = 57) and an unstable group (n = 13); We measured the MRI imaging evaluation indexes, including the position of the bone tunnel, graft status, and the anatomical factors; Statistical methods were used to compare the differences of imaging evaluation indexes between the two groups; The prediction equation was constructed and ROC curve was used to compare the prediction efficiency of independent prediction factors and prediction equation...

CONTEXT: Athletes with anterior cruciate ligament (ACL) reconstruction exhibit increased cortical motor planning during simple sensorimotor tasks compared to healthy controls. This may interfere with proper decision-making during time-constrained movements elevating the re-injury risk. OBJECTIVE: To compare cortical motor planning and biomechanical stability during jump-landings between participants with ACL-reconstruction and healthy individuals. DESIGN: Cross-sectional exploratory study...

CONTEXT: Higher knee function is linked to psychological readiness to return to sport following anterior cruciate ligament reconstruction (ACLR). Individuals with ACLR participate in less physical activity compared to matched uninjured controls, yet the association between knee function and physical activity following ACLR remains unclear. OBJECTIVE: To determine the association between patient-reported knee function measured with the Knee Injury and Osteoarthritis Outcomes Score Quality of Life (KOOS-QOL), daily steps, and minutes spent in moderate to vigorous physical activity (MVPA) in individuals with ACLR...

CASE: Iliotibial band (ITB) autograft is used for anterior cruciate ligament (ACL) reconstruction in prepubescent patients. No reports have described ITB salvage techniques for failed reconstruction. We describe a 13-year-old boy who sustained a multiligamentous knee injury, experienced a failed primary reconstruction, and required a revision ITB ACL, lateral collateral ligament, and posterior lateral corner reconstruction with reuse of his ITB autograft. At the 2-year follow-up, he returned to playing competitive sports...

Anterior cruciate ligament (ACL) graft failure rate has been reported to be greater than 5% at 5 years. Our study evaluated ACL excursion with anatomic and nonanatomic femoral and tibial tunnels to determine optimal flexion angle to tension the ACL to minimize excursion. Ten cadaveric knee specimens were used. The ACL was sectioned and the femoral and tibial attachments were marked. A 1/16-inch drill created a tunnel in the center of the ACL footprint on the tibia and femur and additional tunnels were made 5 mm from this...

Background: Tenosynovial giant-cell tumor (GCT) arising from cruciate ligaments consists a rather rare entity. Predominantly areas where this tumor appears are the palmar sides of fingers and toes. The involvement of larger joints such as the knee or the ankle is rather rare, but, in the case of synovial joints, the knee joint is particularly affected. Furthermore, rare seems to be the intra-articular localization of the tenosynovial GCT of the tendon sheath. Hereby, we present an arthroscopic approach of treatment with two cases...

Distal patellar tendon avulsions are rare injuries in healthy individuals, and to date, no case affecting skeletally mature teenagers and adolescents has been reported. In the majority of cases, distal patellar tendon avulsions are associated with severe intra-articular knee lesions, signifying a high-energy trauma. We present the case of a 15.5-year-old female who was admitted to the emergency department after a knee injury. The mechanism of injury was a combination of landing after a jump off a scooter and sudden deceleration with a fixed foot...

AIMS: MRI has been suggested as an objective method of assessing anterior crucate ligament (ACL) graft "ligamentization" after reconstruction. It has been proposed that the MRI appearances could be used as an indicator of graft maturity and used as part of a return-to-sport assessment. The aim of this study was to evaluate the correlation between MRI graft signal and postoperative functional scores, anterior knee laxity, and patient age at operation. METHODS: A consecutive cohort of 149 patients who had undergone semitendinosus autograft ACL reconstruction, using femoral and tibial adjustable loop fixations, were evaluated retrospectively postoperatively at two years...

BACKGROUND: Articular cartilage and meniscal damage are commonly encountered and often treated at the time of anterior cruciate ligament reconstruction (ACLR). Our understanding of how these injuries and their treatment relate to outcomes of ACLR is still evolving. HYPOTHESIS/PURPOSE: The purpose of this study was to assess whether articular cartilage and meniscal variables are predictive of 10-year outcomes after ACLR. We hypothesized that articular cartilage lesions and meniscal tears and treatment would be predictors of the International Knee Documentation Committee (IKDC), Knee injury and Osteoarthritis Outcome Score (KOOS) (all 5 subscales), and Marx activity level outcomes at 10-year follow-up after ACLR...

INTRODUCTION: The treatment of underlying comorbidities is a field of rising interest in cartilage repair surgery. The aim of this study was to analyze the current practice of concomitant surgeries in cartilage repair of the knee especially in the medial or lateral femorotibial compartment. Type, frequency and distribution of additional surgeries for correction of malalignment, knee instability and meniscus deficiency should be evaluated. METHODS: Baseline data of 4968 patients of the German Cartilage Registry (KnorpelRegister DGOU) were analyzed regarding the distribution of concomitant surgeries in addition to regenerative cartilage treatment...

Classification algorithms determine the similarity of an observation to defined classes, e.g., injured or healthy athletes, and can highlight treatment targets or assess progress of a treatment. The primary aim was to cross-validate a previously developed classification algorithm using a different sample, while a secondary aim was to examine its ability to predict future ACL injuries. The examined outcome measure was 'healthy-limb' class membership probability, which was compared between a cohort of athletes without previous or future (No Injury) previous (PACL) and future ACL injury (FACL)...

Background: Graft choice for pediatric anterior cruciate ligament reconstruction (ACLR) is determined by several factors. There is limited information on the use and outcomes of allograft ACLR in pediatric patients. The purpose of this systematic review and meta-analysis was to quantify reported failure rates of allograft versus autograft ACLR in patients ≤19 years of age with ≥2 years of follow-up. We hypothesized that there would be higher rates of failure for allograft compared with autograft ACLR in this population...

BACKGROUND: There is concern that utilization of lateral extra-articular tenodesis (LET) in conjunction with anterior cruciate ligament (ACL) reconstruction (ACLR) may disturb lateral compartment contact mechanics and contribute to joint degeneration. HYPOTHESIS: ACLR augmented with LET will alter lateral compartment contact mechanics in response to simulated pivoting maneuvers. STUDY DESIGN: Controlled laboratory study. METHODS: Loads simulating a pivot shift were applied to 7 cadaveric knees (4 male; mean age, 39 ± 12 years; range, 28-54 years) using a robotic manipulator...

Anterior cruciate ligament (ACL) reconstruction is successful at restoring stability to return ACL injured patients to high demand work, sports, and recreational activities. The development of post-traumatic osteoarthritis (OA) in roughly half of patients just 10-15 years after ACLR highlight the need to improve clinical care pathways. Graft failure and reinjury rates which further increase OA risk also remain high for younger and more active patients. The biological components of joint recovery and graft incorporation therefore impact short and long-term clinical outcomes...

Background Multiple hereditary exostoses (MHE) also known as Multiple Osteochondromas is a rare benign bone tumour disease, characterized by multiple osteocartilaginous masses. The knee is one of the most affected sites. Anterior cruciate ligament (ACL) surgery is the most common and generally most successful surgical knee procedure; however, the association between MHE and ACL reconstruction is very rare and may represent a challenging procedure because of the anatomical anomaly related to presence of multiple masses around the knee...

Background Anterior cruciate ligament reconstructions are a very frequent surgery. The key role of the anterolateral ligament in the knee rotational stability has been undelighted in recent years. Extra-articular tenodesis in association with ACL reconstructions, serves to eliminate anterolateral rotatory instability. The aim of our study is to compare treated knees with the contralateral uninjured knee in those cases whom been treated with ACL arthroscopic reconstruction and lateral extra-articular tenodesis in revision surgery, and evaluate clinical results with kinematic and kinetic examinations methods...
