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...
A burst-superimposition technique was used to assess the strength of quadriceps femoris muscle in three groups patients. Group 1 comprised twenty patients who had a torn anterior cruciate ligament knee and reconstruction one six months after injury. 2 twelve for an average (a subacute tear). 3 eight two years chronic The Groups not operation ligament. no evidence failure activation involved quadriceps, but nine reflex inhibition contraction muscle.
To assess the accuracy and reliability of multiple signs anterior cruciate ligament (ACL) tears with magnetic resonance (MR) imaging.Two independent reviewers retrospectively evaluated 103 sets ACL MR images for presence 22 tears. There were 43 patients 58 whose ACLs proved to be intact at surgery. Although variable imaging protocols used, T1- T2-weighted obtained in nearly all patients. Direct nonvisualization, intrinisc abnormalities, associated osseous cartilage other indirect...
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...
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. Patients were divided...
Gymnast wrist pain syndrome presents a difficult diag nostic and therapeutic challenge. It is common debilitating among gymnasts, resulting in reduction training performance, may be the result of response to repetitive trauma during period growth development. This study was undertaken define characterize factors contributing causes development gymnast establish an effective means systematic compre hensive evaluation treatment. Thirty-eight collegiate gymnasts (20 UCLA: 9 female, 11 male; 18...
Sequential assembly of the human spliceosome on RNA transcripts regulates splicing across transcriptome. The core component PRPF8 is essential for through its participation in ribonucleoprotein (RNP) complexes splice-site recognition, branch-point formation and catalysis. deficiency linked to diseases like retinitis pigmentosa or myeloid neoplasia, but genome-wide effects constitutive alternative remain unclear. Here, we show that alterations patterns transcriptome occur conditions...
Background: Revision anterior cruciate ligament (ACL) reconstruction has been documented to have worse outcomes compared with primary ACL reconstructions. Purpose/Hypothesis: The purpose of this study was determine if the prevalence, location, and/or degree meniscal and chondral damage noted at time revision predicts activity level, sports function, osteoarthritis symptoms 2-year follow-up. hypothesis that loss high-grade will result in lower levels, decreased participation, more pain,...
Background: While revision anterior cruciate ligament reconstruction (ACLR) can be performed to restore knee stability and improve patient activity levels, outcomes after this surgery are reported inferior those primary ACLR. Further reoperations ACLR have an even more profound effect on satisfaction outcomes. However, there is a current lack of information regarding the rate risk factors for subsequent Purpose: To report reoperations, procedures performed, reoperation 2 years Study Design:...
Background: Although graft choice may be limited in the revision setting based on previously used grafts, most surgeons believe that for anterior cruciate ligament (ACL) reconstruction is an important factor related to outcome. Hypothesis: In ACL setting, there would no difference between autograft and allograft rerupture rate patient-reported outcomes (PROs) at 6-year follow-up. Study Design: Cohort study; Level of evidence, 2. Methods: Patients who had surgery were identified prospectively...
Background: Knees undergoing revision anterior cruciate ligament (ACL) reconstruction typically have more intra-articular injuries than do knees primary reconstruction. Hypothesis: Previous partial meniscectomy (PM) is associated with a higher rate of chondral lesions at ACL reconstruction, whereas previous meniscal repair (MR) not compared no surgery. Study design: Cohort study (Prevalence); Level evidence, 2. Methods: Data from multicenter cohort was reviewed to determine the history prior...
Background: The occurrence of physiologic knee hyperextension (HE) in the revision anterior cruciate ligament reconstruction (ACLR) population and its effect on outcomes have yet to be reported. Hypothesis/Purpose: prevalence HE ACLR 2-year outcome were studied with hypothesis that preoperative ≥5° is a risk factor for (ACL) graft rupture. Study Design: Cohort study; Level evidence, 2. Methods: Patients undergoing identified prospectively enrolled between 2006 2011. inclusion criteria...
Excellent results have been reported with posterior stabilized total knee arthroplasty. A common complication relating to patellofemoral articulation is patellar clunk syndrome. Patellar syndrome occurs when a fibrous nodule develops just proximal the button. At approximately 30° 45° from full extension, catches anterior flange of femoral prosthesis, resulting in and painful range motion. The present study examines use arthroscopic debridement for this disorder. Thirty consecutive patients...
Football players lose 3.5 to 5 kg of body weight during preseason practices because heavy sweating. This fluid may be difficult replace when occur 2 times per day on consecutive days.Football are hypohydrated twice-a-day training in a hot, humid environment.Descriptive laboratory study.In 10 college football players, was measured, and blood urine samples were obtained before after days through 8 training. Baseline subjects euhydrated. Blood used calculate plasma volume changes. Urine...
Knees undergoing revision anterior cruciate ligament reconstruction (rACLR) have a high prevalence of articular cartilage lesions.The chondrosis at the time rACLR is associated with meniscal status and lower extremity alignment.Cross-sectional study; Level evidence, 3.Data from prospective Multicenter ACL Revision Study (MARS) cohort were reviewed to identify patients preoperative alignment films. Lower was defined by weightbearing line (WBL) as percentage tibial plateau width, while...
Articular cartilage health is an important issue following anterior cruciate ligament (ACL) injury and primary ACL reconstruction. Factors present at the time of reconstruction may influence subsequent progression articular damage.Larger meniscus resection reconstruction, increased patient age, body mass index (BMI) are associated with odds worsened damage revision reconstruction.Case-control study; Level evidence, 3.Subjects who had data in databases Multicenter Orthopaedics Outcomes...
Sagittal craniosynostosis is managed with a wide variety of operative strategies. The current investigation compares the clinical outcomes two widely performed techniques: pi craniectomy and minimally invasive endoscopic strip (ESC) followed by helmet therapy.
Neglected tears of the patellar tendon due to loss active extension remain a difficult therapeutic endeavor. The goals in approach this diagnosis include restoration both structural and functional integrity extensor mechanism. A procedure has been developed utilizing Z-shortening tendon, Z-lengthening quadriceps semitendinosis gracilis as biologic splint. This technique allows establishment preoperative goals, including muscle-tendon complex its anatomic position, function, preservation...
Background: Meniscal preservation has been demonstrated to contribute long-term knee health. This a successful intervention in patients with isolated tears and associated anterior cruciate ligament (ACL) reconstruction. However, the results of meniscal repair setting revision ACL reconstruction have not documented. Purpose: To examine prevalence 2-year operative success rate repairs setting.
