Background: There is a lack of high-quality population-based literature describing the epidemiology primary anterior shoulder dislocation. Purpose: To (1) calculate incidence density rate (IDR) dislocation requiring closed reduction (CR; “index event”) in general population and demographic subgroups, (2) determine risk factors for repeat CR. Study Design: Cohort study (prognosis); Level evidence, 2. Methods: All patients who underwent CR by physician Ontario between April 2002 September 2010...
Abstract Patients with late-stage Kellgren-Lawrence knee osteoarthritis received a single intra-articular injection of 1, 10, or 50 million bone marrow mesenchymal stromal cells (BM-MSCs) in phase I/IIa trial to assess safety and efficacy using broad toolset analytical methods. Besides safety, outcomes included patient-reported outcome measures (PROMs): Knee Injury Osteoarthritis Outcome Score (KOOS) Western Ontario McMaster Universities Index (WOMAC); contrast-enhanced magnetic resonance...
The goal of the Objective Structured Clinical Examination (OSCE) in Competency-based Medical Education (CBME) is to establish a minimal level competence. purpose this study was 1) determine credibility and acceptability modified Angoff method standard setting CBME, using Borderline Group (BG) Regression (BLR) as reference standard; 2) if it feasible set different standards for junior senior residents, 3) desired characteristics judges applying method. results previous OSCE (21 18 six...
Primary anterior cruciate ligament (ACL) reconstruction is known to have excellent outcomes, but many patients do not return their preinjury level of sport participation. Previous studies used subjective outcome scores evaluate this discrepancy, none date has qualitative, in-depth patient interviews.To understand the factors influencing a patient's decision his or her after ACL reconstruction.Extrinsic and intrinsic may affect one's primary despite good functional knee scores.Case series;...
Perineural and IV dexmedetomidine have each been suggested to prolong the duration of analgesia when administered in conjunction with peripheral nerve blocks. In first randomized, triple-masked, placebo-controlled trial date, authors aimed define compare efficacy perineural prolonging analgesic single-injection interscalene brachial plexus block (ISB) for outpatient shoulder surgery.Ninety-nine patients were randomized receive ISB using 15 ml ropivacaine, 0.5%, 0.5 μg/kg perineurally (DexP...
Reoperation rates following open reduction and internal fixation (ORIF) of midshaft clavicle fractures have been described, but reported nonunion, malunion, infection, implant removal varied. We sought to establish baseline of, risk factors for, reoperations ORIF in a large population cohort.Administrative databases were used identify patients sixteen sixty years age who had undergone an closed, fracture from April 2002 2010. The primary outcome was reoperation within two (isolated removal,...
Background: Evidence for the success of a meniscal repair performed alone versus combined with anterior cruciate ligament reconstruction (ACLR) is equivocal. No large-scale comparative studies exist regarding this issue. Hypothesis: In general population, in presumed stable knee has same rate reoperation as ACLR. Study Design: Cohort study; Level evidence, 3. Methods: All repairs ACLR Ontario, Canada, between July 2003 and March 2008 patients aged 15 to 60 years were identified using...
Anatomic techniques of ankle ligament repair have the advantage restoring anatomy and kinematics joint. This study presents a technique for anatomic reconstruction lateral complex by way advancement using suture anchors associated with immediate protected full weightbearing; 2- to 5-year clinical outcomes are reported.This providing an secure fixation will enable early rehabilitation immediate, weightbearing, favorable outcomes.Case series; Level evidence, 4.Fifty-five patients chronic...
Background: Anterior cruciate ligament reconstruction (ACLR) is routinely performed for symptomatic instability. Although it a common procedure, there remain differences in surgical technique. Hospital administrative records public health care system were used to investigate the effect of patient, provider, and factors on risk revision ACLR. Purpose: To define rate ACL reoperation Ontario, Canada, including both ipsilateral contralateral primary procedures. Study Design: Cohort study; Level...
We performed a biomechanical comparison of two ro tator cuff repair techniques using fresh-frozen human cadavers. Nine pairs cadaveric shoulders had stan dardized full-thickness tears made at the supraspina tus tendon insertion. One each pair was repaired by pulling into bone trough in humeral head standard su tures. The remaining half anchor sutures. repairs were tested servohydraulically operated material testing system. suture significantly stronger than technique irrespective quality....
Arthroscopically assisted arthrodesis of the ankle was performed in nineteen patients who were selected because they had osteoarthrosis with minimum or no deformity ankle. After arthroscopic resection synovial membrane, subchondral bone, and cartilage from tibial, fibular, talar articular surfaces, three percutaneous, cannulated, cancellous screws used for internal fixation. Of these patients, ten radiographic evidence union by second postoperative month; five, third; one, fifth; sixth. Two...
Objectives: Anterior cruciate ligament reconstruction (ACLR) is routinely performed to treat symptomatic instability. Despite being a common procedure, significant variation persists in technique and graft choice. How patient, provider surgical factors influence the risk of revision or contralateral primary ACLR has not been investigated using administrative data. The goal our study was define rate for ACL re-operation Ontario. Methods: All elective Ontario, Canada from July 2003 March 2008...
Arthroscopic shoulder stabilization is known to have excellent functional results, but many patients do not return their preinjury level of sport, with play rates reported between 48% and 100% despite good outcome scores.To understand specific subjective psychosocial factors influencing a patient's decision sport after arthroscopic stabilization.Case series; Level evidence, 4.Semistructured qualitative interviews were conducted aged 18 40 years who had undergone primary minimum 2-year...
Knowledge of the rate and risk factors for re-revision, reoperation, readmission after revision anterior cruciate ligament reconstruction (ACLR) is limited.To determine ACLR.Descriptive epidemiology study.All patients who underwent first ACLR in Ontario, Canada, from January 2004 to December 2010 were identified followed until 2012. Exclusions included age <16 years, previous osteotomy, or multiligament knee reconstruction. The main outcome was re-revision ACLR. Secondary outcomes...
Background: Clinical studies of shoulder dislocations typically include adult patients (>16 years age). Only small case series aged 10 to 16 are available guide management. Purpose: Using a cohort years, this study sought determine (1) the incidence density rate (IDR) primary anterior requiring closed reduction (CR) and (2) risk factors for repeat CR. Study Design: Cohort (prognosis); Level evidence, 2. Methods: With use administrative databases, who underwent CR dislocation in Ontario,...
Background: Evidence regarding the risk of end-stage osteoarthritis following cruciate ligament reconstruction is based upon small sample sizes and radiographic, rather than clinical, criteria. The goals this study were to determine knee arthroplasty, a surrogate for osteoarthritis, reconstruction, identify patient, provider, surgical factors that influence arthroplasty risk. Methods: Using administrative databases, we identified all patients who sixteen sixty years age had undergone in...
Context: The number of adults with osteoarthritis in the United States is expected to nearly double from 21.4 million 2005 41.1 by 2030. As a result, medical costs and associated comorbidity will exponentially increase coming decades. In past decade, mesenchymal stem cells (MSCs) have emerged as novel treatment for degenerative joint disease. Evidence Acquisition: PubMed (from 1990 2013) was searched identify relevant studies. Reference lists included studies were also reviewed. Study...
