The effects of ACL-reconstruction on lower extremity joint mechanics during performance of the Star Excursion Balance Test (SEBT) and Single Leg Hop (SLH) are limited. The purpose of this study was to determine if altered lower extremity mechanics occur during the SEBT and SLH after ACL-reconstruction. One female Division I collegiate athlete performed the SEBT and SLH tasks, bilaterally, both before ACL injury and 27 months after ACL-reconstruction. Maximal reach, hop distances, lower extremity joint kinematics and moments were compared between both time points...

BACKGROUND: The long-term prognosis and risk factors for quality of life and disability after anterior cruciate ligament (ACL) reconstruction remain unknown. Hypothesis/Purpose: Our objective was to identify patient-reported outcomes and patient-specific risk factors from a large prospective cohort at a minimum 10-year follow-up after ACL reconstruction. We hypothesized that meniscus and articular cartilage injuries, revision ACL reconstruction, subsequent knee surgery, and certain demographic characteristics would be significant risk factors for inferior outcomes at 10 years...

Background: Traditional ACL reconstruction with non-anatomic techniques can demonstrate unsatisfactory long-term outcomes with regards instability and the degenerative knee changes observed with these results. Anatomic ACL reconstruction attempts to closely reproduce the patient's individual anatomic characteristics with the aim of restoring knee kinematics, in order to improve patient short and long-term outcomes. We designed an arthroscopic, patient-specific, ACL femoral tunnel guide to aid anatomical placement of the ACL graft within the femoral tunnel...

Background: Patient-reported outcome (PRO) surveys have become increasingly important in both improving patient care and assessing outcomes. Purpose/Hypothesis: The purpose of this study was to evaluate which variables are associated with compliance with completing PRO surveys in patients who have undergone anterior cruciate ligament reconstruction (ACLR). The authors hypothesized that older patient age and longer time since ACLR would be associated with lower completion rates of PRO surveys preoperatively and at postoperative time points...

Anterior cruciate ligament (ACL) tears are a common sports-related knee injury that increases the risk of developing post-traumatic osteoarthritis (OA). During OA progression bone microarchitecture changes in the affected knee, however, little is known about bone microarchitecture in knees with early stage OA. The purpose of this study is to investigate in a cohort of females predisposed to develop OA how bone microarchitecture in ACL reconstructed knees differs from uninjured contralateral knees as well as healthy control knees and how this relates to early changes in OA...

OBJECTIVES: Compare maximum plantar force (Fmax) during running in soccer players following anterior cruciate ligament reconstruction (ACLR) as they pass return to sport (RTS) criteria. DESIGN: Case control study. METHODS: Soccer players after ACLR (n=16) and matched healthy controls (n=16) ran on a treadmill at 12, 14 and 16km/h while plantar loading data was measured using an in-shoe pressure system (Pedar-X, Novel). Fmax and contact time of the injured and uninjured limbs in athletes <9months post-ACLR and those ≥9months ACLR were compared to healthy players (no ACLR)...

BACKGROUND: Anterior cruciate ligament (ACL) ruptures may lead to knee dysfunctions later in life. Single-leg tasks are often evaluated, but bilateral movements may also be compromised. Our aim was to use curve analyses to examine double-leg drop-jump kinematics in ACL-reconstructed, ACL-deficient, and healthy-knee cohorts. METHODS: Subjects with unilateral ACL ruptures treated more than two decades ago (17-28years) conservatively with physiotherapy (ACLPT , n=26) or in combination with reconstructive surgery (ACLR , n=28) and healthy-knee controls (n=25) performed 40-cm drop-jumps...

BACKGROUND: To determine the association between time from injury to ACL reconstruction (TimeInjury-ACLR ) and biochemical markers of cartilage metabolism and inflammation six months following ACL reconstruction (ACLR). METHODS: Individuals with a unilateral ACL injury were enrolled at initial presentation in the orthopedic clinic; blood was collected six months following ACLR. Enzyme-linked immunosorbent assays were used to analyze the ratio of serum concentrations of type-II collagen breakdown (C2C) to synthesis (CPII), plasma matrix metalloproteinase-3 (MMP-3), interleukin-6 (IL-6), and serum aggrecan neoepitope (ARGS)...

Anterior cruciate ligament (ACL) reconstruction is one of the most commonly performed procedures in the United States. Although complications are rare in ACL surgery, failure to appreciate them can lead to significant patient morbidity in the short and long terms. More common complications in ACL reconstruction include tunnel malposition, infection, tunnel osteolysis, fixation failure, fracture, arthrofibrosis, graft site morbidity, and deep vein thrombosis or pulmonary embolism. Tunnel malposition is the most common technical error in ACL reconstruction leading to failure...

Anterior cruciate ligament (ACL) is one of the most difficult tissues to heal once injured. Ligament regeneration and tendon-bone junction healing are two major goals of ACL reconstruction. This study aimed to investigate the synergistic therapeutic effects of Stromal cell-derived factor 1(SDF-1)-releasing collagen-silk (CSF) scaffold combined with intra-articular injection of ligament-derived stem/progenitor cells (LSPCs) for ACL regeneration and the amelioration in the long-term complication of osteoarthritis (OA)...

PURPOSE: To compare long-term clinical and radiographic outcomes in patients undergoing either early (group A) or late (group B) surgery after anterior cruciate ligament (ACL) injury. METHODS: ACL reconstruction using hamstring tendon autografts was performed in 30 patients in group A (median age, 23 years; range, 17-49 years) and 31 patients in group B (median age, 27 years; range, 17-38 years). The patients in group A were operated on within 5 months (median, 3 months; range, 2-5 months) of injury, whereas those in group B were operated on more than 24 months (median, 30 months; range, 24-48 months) after injury...

BACKGROUND: Both single-bundle (SB) and double-bundle (DB) techniques were widely used in anterior cruciate ligament (ACL) reconstruction recently. Nevertheless, up to now, no consensus has been reached on whether the DB technique was superior to the SB technique. Moreover, follow-up of the included studies in the published meta-analyses is mostly short term. Our study aims to compare the mid- to long-term outcome of SB and DB ACL reconstruction concerning knee stability, clinical function, graft failure rate, and osteoarthritis (OA) changes...

Graft tissues within bone tunnels remain mobile for a long time after anterior cruciate ligament (ACL) reconstruction. However, whether the graft-tunnel friction affects the finite element (FE) simulation of the ACL reconstruction is still unclear. Four friction coefficients (from 0 to 0.3) were simulated in the ACL-reconstructed joint model as well as two loading levels of anterior tibial drawer. The graft-tunnel friction did not affect joint kinematics and the maximal principal strain of the graft. By contrast, both the relative graft-tunnel motion and equivalent strain for the bone tunnels were altered, which corresponded to different processes of graft-tunnel integration and bone remodeling, respectively...

BACKGROUND: Meaningful change scores in the Knee injury and Osteoarthritis Outcome Score (KOOS) in patients undergoing anterior cruciate ligament (ACL) reconstruction have not yet been established. PURPOSE: To define the minimal important change (MIC) for the KOOS after ACL reconstruction. STUDY DESIGN: Cohort study (diagnosis); Level of evidence, 2. METHODS: KOOS and anchor questions with 7-point scales ranging from "better, an important improvement" to "worse, an important worsening" were completed postoperatively by randomly chosen participants from the Norwegian Knee Ligament Registry...

PURPOSE: Anterior cruciate ligament (ACL) injuries are frequently not isolated injuries and damage to the menisci and articular cartilage surfaces is common. The concomitant presence of meniscal and chondral damage has the potential to influence patient outcomes following ACL reconstruction surgery and especially following revision ACL reconstruction where these findings are more common. However, study results regarding the mid-term outcome have been inconsistent. The purpose of this study was to compare mid-term patient-reported outcomes and return to sport in patients with and without meniscal and chondral pathology at the time of revision ACL reconstruction surgery...

PURPOSE: Anterior cruciate ligament (ACL) rupture commonly occurs in conjunction with articular cartilage injury. However, there is no consensus on the most appropriate rehabilitation which should be carried out for ACL reconstruction (ACLR) and the surgical management of articular cartilage lesions of the knee. The purpose of this study was to systematically review the literature to investigate the recommended rehabilitation protocol for patients undergoing ACLR with concomitant articular cartilage injury with a view to develop guidelines on the most appropriate treatment...
