Different surgical methods of graft fixation in ACL re construction were examined to determine the effects on mechanical properties reconstructed ACL. Ten human cadavers used this study. Six different types grafts studied. The tendon removed from each cadaver and fixed femurs tibias as substitutes with methods, leaving femur-reconstructed graft- tibia preparations. techniques staple fixation, tying sutures over buttons, screw fixation. In latter, screws introduced through femoral tibial...
Anterior cruciate ligament (ACL) reinjury results in worse outcomes and increases the risk of posttraumatic osteoarthritis.
Background: Tearing an anterior cruciate ligament (ACL) graft is a devastating occurrence after ACL reconstruction (ACLR). Identifying and understanding the independent predictors of ACLR failure important for surgical planning, patient counseling, efforts to decrease risk failure. Hypothesis: Patient variables will predict ACLR. Study Design: Prospective cohort study. Methods: A multicenter group initiated study in 2002 identify outcomes, including First, control confounders, single...
Background: There is limited information on outcomes and return to play (RTP) after anterior cruciate ligament reconstruction (ACLR) in soccer athletes. Purpose: The purpose of this study was (1) test the hypotheses that player sex, side injury, graft choice do not influence RTP (2) define risk for future ACL injury players ACLR. Study Design: Cohort study; Level evidence, 3. Methods: Soccer a prospective cohort were contacted determine Information regarding if when they returned play, their...

Background: Subsequent surgeries have a profound effect on patient satisfaction and outcome after primary anterior cruciate ligament reconstruction (ACLR). There been no prospective studies to date describing the rate predictors (surgical variables) of all subsequent knee at short-term midterm follow-up along with analyses surgical variables that are associated surgeries. Purpose: To report variables. Study Design: Case-control study; Level evidence, 3. Methods: A total 980 patients (540...
There is a relative paucity of data regarding the effect anterior cruciate ligament (ACL) reconstruction on ability American high school and collegiate football players to return play at same level competition as before their injury or progress next competition.(1) To identify percentage who successfully returned previous competition, (2) investigate self-reported performance for those able reason(s) not returning play, (3) elucidate risk factors responsible being performance.Cohort study;...
Background: Most surgeons believe that graft choice for anterior cruciate ligament (ACL) reconstruction is an important factor related to outcome; however, revision may be limited due previously used grafts. Hypotheses: Autograft use would result in increased sports function, activity level, and decreased osteoarthritis symptoms (as measured by validated patient-reported outcome instruments). failure reoperation rate 2 years after ACL reconstruction. Study Design: Cohort study; Level of...
Background: The long-term prognosis and risk factors for quality of life disability after anterior cruciate ligament (ACL) reconstruction remain unknown. Hypothesis/Purpose: Our objective was to identify patient-reported outcomes patient-specific from a large prospective cohort at minimum 10-year follow-up ACL reconstruction. We hypothesized that meniscus articular cartilage injuries, revision reconstruction, subsequent knee surgery, certain demographic characteristics would be significant...
Anterior cruciate ligament (ACL) reconstruction rehabilitation has evolved over the past 20 years. This evolution been driven by a variety of level 1 and 2 studies.The MOON Group is collection orthopaedic surgeons who have developed prospective longitudinal cohort ACL patients. To standardize management these patients, we developed, in conjunction with our physical therapy committee, an evidence-based guideline.Clinical review.Level 2.This review was based on systematic reviews studies....
Fifty-four patients with anterior cruciate ligament tears that were arthroscopically reconstructed within 3 months of initial injury prospectively evaluated. Patients grade medial collateral ligament, lateral or posterior excluded. Eighty percent our had a bone bruise present on the magnetic resonance image, 68% in femoral condyle. Two latter findings--an abnormal articular cartilage signal (P = 0.02) and thin impacted subchondral 0.03)--had significant relationship to overlying cartilage....
The purpose of this study was to examine the effect initial tensioning on outcome reconstruction ACL. ACLs 15 adult mongrel dogs were excised and reconstructed. In first five dogs, both knees reconstructed using medial one- third patellar tendon. graft fixed under a tension 1 N (0.22 pounds) in one knee 39 (8.8 opposite knee. remainder reconstructions augmented with Dacron prostheses. Tensioning compo nents either contralateral or disproportionate tensions applied autogenous material...
Background: The predictors of anterior cruciate ligament reconstruction (ACLR) outcome at 6 years as measured by validated patient-based instruments are unknown. Hypothesis: Certain variables evaluated the time ACLR will predict return to sports function (as International Knee Documentation Committee [IKDC] questionnaire and injury Osteoarthritis Outcome Score [KOOS] Sports Recreation subscale), knee-related quality life (KOOS Related Quality Life activity level (Marx Activity Scale)....
Objective The study was conducted to quantify activity level 2 years after anterior cruciate ligament reconstruction and identify explanatory variables measured at baseline (demographics, concomitant meniscal/articular cartilage injuries their treatment) associated with short-term follow-up (2 years). Study Design Cohort study; Level of evidence, 2. Methods In 2002, the Multicenter Orthopaedic Outcomes Network (MOON) consortium began enrolling patients undergoing 6 recruitment sites. current...
We conducted a retrospective study on 50 patients with recurrent posterior shoulder instability. Twenty- five were treated conservatively specific rehabilitation program strengthening the rotator cuff. The other 25 patients, who did not improve reha bilitation, underwent surgical reconstruction, major ity of these being soft tissue repairs. Recurrence in surgically group averaged 72% while that was 96%. However, 50% those and 68% felt their symptoms im proved. In view high recurrence rate...
Background: At the time of anterior cruciate ligament (ACL) reconstruction, there are usually concurrent meniscal and articular cartilage injuries. It is unclear if a significant difference between intra-articular injuries at primary ACL reconstruction compared with revision reconstruction. Purpose: To compare found surgery to determine associations specific findings. Study Design: Cohort study (prevalence); Level evidence, 2. Methods: Primary surgeries were identified from Multicenter...
Despite research on the increased risk of anterior cruciate ligament tears in female athletes, few studies have addressed sex differences incidence associated intraarticular injuries.When patients are stratified by sport and competition level, no exist either mechanism injury or pattern injuries observed at reconstruction.Prospective cohort study.Two hundred twenty-one athletes undergoing reconstruction met our inclusion criteria tear as a singular event without reinjury history prior...
The factors that lead to patients failing multiple anterior cruciate ligament (ACL) reconstructions are not well understood.Multiple-revision ACL reconstruction will have different characteristics than first-time revision in terms of previous and current graft selection, mode failure, chondral/meniscal injuries, surgical charactieristics.Case-control study; Level evidence, 3.A prospective multicenter database was utilized for the time period from March 2006 June 2011.
