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...
<h3>Importance</h3> Controversy exists about the preferred surgical approach for total hip arthroplasty (THA). <h3>Objective</h3> To determine whether an anterior is associated with lower risk of complications than either a lateral or posterior approach. <h3>Design, Setting, and Participants</h3> Population-based retrospective cohort study all adults in Ontario, Canada, who had undergone primary THA osteoarthritis between April 1, 2015, March 31, 2018. All patients were followed up over...
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,...
The aim of the present study was to compare 30- and 90-day re-admission rates complication outpatient inpatient total shoulder arthroplasty (TSA).The United States Medicare Standard Analytical Files database questioned identify patients who had undergone or TSA between 2005 2012. Patient characteristics were compared two groups using chi-squared analysis. Multivariate logistic regression analysis used control for differences in baseline patient terms post-operative complications within 90...
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...
Total knee arthroplasty (TKA) is one the most common elective procedures in world. Post-operative infection of its devastating complications, often necessitating multiple additional surgeries. We aimed to describe relationship between surgical duration and risk deep following primary TKA.In this cohort study we analyses TKAs done 2009 2016 Ontario, Canada. utilized restricted cubic splines identify a threshold that was associated with an increased for requiring surgery. Patients 'short'...
There is increasing interest in outpatient shoulder arthroplasty (SA); however, the clinical evidence behind this practice sparse. The purpose of study was to assess safety SA performed an ambulatory surgery center and determine patient factors that are associated with increased risk for perioperative complications or dissatisfaction.Patient demographics operative variables were collected retrospectively patients undergoing at 2 centers a minimum follow-up 90 days. Patients completed...
Osteochondral allograft transplantation (OCA) is often performed with concomitant meniscus (MAT) as a strategy for knee joint preservation, although to date, the effect of MAT on outcomes and failure rates after OCA has not been assessed.To determine clinical patients undergoing compared matched cohort isolated OCA.Control study; Level evidence, 3.Patients who underwent medial or lateral femoral condyle without by single surgeon were group (ipsilateral compartment). The per age, sex, body...
Little is known regarding the rates and risk factors for long-term postoperative opioid use among opioid-naïve patients undergoing elective shoulder surgery.To identify (1) proportion of surgery, (2) these patients, (3) associated with use.Cohort study; Level evidence, 3.A retrospective review a private administrative claims database was performed to those individuals who underwent surgery between 2007 2015. "Opioid-naïve" were identified as had not filled an prescription in 180 days before...
