Establishing Age- and Sex-Specific Norms for Pediatric Return-to-Sports Physical Performance Testing.

Background: Graft tears and contralateral anterior cruciate ligament (ACL) tears are common in pediatric athletes after ACL reconstruction. Use of objective return-to-sports (RTS) criteria, in particular physical performance tests (PPTs), is believed to reduce the incidence of secondary injury; however, pediatric norms for these tests are unknown.

Purpose: To establish a proof of concept for the creation of age- and sex-based norms for commonly used RTS PPTs in healthy pediatric athletes, allowing the creation of growth curves for clinical referencing.

Healthy Pediatric Athletes Have Significant Baseline Limb Asymmetries on Common Return-to-Sport Physical Performance Tests.

Background: Return to sport (RTS) after anterior cruciate ligament (ACL) reconstruction in children is associated with a much higher risk (∼30%) of subsequent ACL injury than in adults. Most RTS testing protocols use a limb symmetry index (LSI) ≥90% on physical performance tests (PPTs) to assess an athlete's readiness for sport. This assumes that, in a healthy state, the physical performances across both lower extremities are and should be equal.

The Role of Radiotherapy for Chordoma Patients Managed With Surgery: Analysis of the National Cancer Database.

Study Design: Retrospective review.

Objective: To determine if adjuvant radiation therapy (RT) improves overall survival (OS) following surgical resection of chordomas.

Summary Of Background Data: The role of RT for the treatment of chordomas remains incompletely described.

Race is an independent predictor of survival in patients with soft tissue sarcoma of the extremities.

Background: In the United States, race and socioeconomic status are well known predictors of adverse outcomes in several different cancers. Existing evidence suggests that race and socioeconomic status may impact survival in soft tissue sarcoma (STS). We investigated the National Cancer Database (NCDB), which contains several socioeconomic and medical variables and contains the largest sarcoma patient registry to date.

Inpatient Consults and Complications During Primary Total Joint Arthroplasty in a Bundled Care Model.

Background: The Centers for Medicare and Medicaid Services (CMS) are implementing changes in hospital reimbursement models for total joint arthroplasty (TJA), moving to value-based bundled payments from the fee-for-service model. The purpose of this study is to identify consults and complications during the perioperative period that increase financial burden.

Methods: We combined CMS payment data for inpatient, professional, and postoperative with retrospective review of patients undergoing primary TJA and developed profiles of patients included in the Comprehensive Care for Joint Replacement bundle undergoing TJA.

Midterm Results of the Salto Talaris Total Ankle Arthroplasty.

Background: The Salto Talaris total ankle replacement is a modern fixed-bearing implant used to treat symptomatic ankle arthritis with the goals of providing pain relief, restoring mechanical alignment, and allowing motion of the ankle joint. The goal of this study was to report the midterm clinical results of one of the largest cohort of patients in the United States who underwent ankle replacement with this prosthesis.

Methods: This is a review of patients with a minimum of 5 years up to 10 years' follow-up.

Percent Body Fat Is More Predictive of Function After Total Joint Arthroplasty Than Body Mass Index.

Background: Obesity has an important impact on the future of total joint arthroplasty; however, the definition and influence of obesity on surgical risks and outcomes remain controversial. Our hypothesis was that percent body fat was better than body mass index (BMI) at identifying clinical risks and patient-reported functional outcomes following arthroplasty.

Methods: Clinical and functional outcomes were collected prospectively in 215 patients undergoing primary total knee arthroplasty (115 patients) or total hip arthroplasty (100 patients) at a mean time of twenty-four months (range, twelve to forty months).

Current Evidence Does Not Support Medicare's 3-Day Rule in Primary Total Joint Arthroplasty.

Patients who undergo total joint arthroplasty and are destined for discharge to an extended-care facility--particularly Medicare beneficiaries--are required to have an inpatient stay of at least 3 consecutive days. The primary objective of this study was to explore the effect of this policy on length of stay. Secondary outcomes were 30-day readmission rate and inpatient rehabilitation gains.

Opioid-Based Analgesia: Impact on Total Joint Arthroplasty.

The objective of this study was to characterize the impact of opioid-based analgesia in total joint arthroplasty. The primary outcomes were incidence of in-hospital complications, length of stay, and discharge destination. Six hundred and seventy-three primary total hip and knee arthroplasties were retrospectively reviewed.

Optimal timing of tracheostomy after trauma without associated head injury.

Background: Controversy exists over optimal timing of tracheostomy in patients with respiratory failure after blunt trauma. The study aimed to determine whether the timing of tracheostomy affects mortality in this population.

Methods: The 2008-2011 National Trauma Data Bank was queried to identify blunt trauma patients without concomitant head injury who required tracheostomy for respiratory failure between hospital days 4 and 21.

Medicare's 3-Day Rule: Time for a Rethink.

A pilot study was undertaken to examine the impact of Medicare's 3-day rule on length of stay (LOS). One hundred consecutive patients who underwent primary total joint arthroplasty and were discharged to extended care facilities were retrospectively reviewed. Based on readiness for discharge criteria, delaying discharge until the third postoperative day increased LOS by 1.

Patient expectation is the most important predictor of discharge destination after primary total joint arthroplasty.

The purpose of this study was to identify preoperative predictors of discharge destination after total joint arthroplasty. A retrospective study of three hundred and seventy-two consecutive patients who underwent primary total hip and knee arthroplasty was performed. The mean length of stay was 2.

Preoperative predictors of extended hospital length of stay following total knee arthroplasty.

The purpose of this study was to identify the preoperative predictors of hospital length of stay after primary total knee arthroplasty in a patient population reflecting current trends toward shorter hospitalization and using readily obtainable factors that do not require scoring systems. A single-center, multi-surgeon retrospective chart review of two hundred and sixty consecutive patients who underwent primary total knee arthroplasty was performed. The mean length of stay was 3.

Preoperative pain level and patient expectation predict hospital length of stay after total hip arthroplasty.

The purpose of this study was to identify preoperative predictors of length of stay after primary total hip arthroplasty in a patient population reflecting current trends toward shorter hospitalization and using readily obtainable factors that do not require scoring systems. A retrospective review of 112 consecutive patients was performed. High preoperative pain level and patient expectation of discharge to extended care facilities (ECFs) were the only significant multivariable predictors of hospitalization extending beyond 2 days (P=0.

Comparison of ST-segment resolution with combined fibrinolytic and glycoprotein IIb/IIIa inhibitor therapy versus fibrinolytic alone (data from four clinical trials).

We compared combination fibrinolytic plus glycoprotein IIb/IIIa inhibitor therapy with stand-alone fibrinolysis with respect to speed and stability of reperfusion in patients who had acute ST-segment elevation myocardial infarction; data were obtained from 654 patients in 4 trials (Integrilin to Manage Platelet Aggregation to Combat Thrombosis in Acute Myocardial Infarction, Platelet Aggregation Receptor Antagonist Dose Investigation and Reperfusion Gain in Myocardial Infarction, Integrilin and Tenecteplase in Acute Myocardial Infarction, and the Fifth Global Use of Strategies to Open Occluded Coronary Arteries) that compared thrombolytics plus lamifiban, eptifibatide, or abciximab with standard thrombolysis. We found significantly faster and more stable ST-segment recovery with combination therapy starting at 60 minutes (56.7% vs 48.

Association of the timing of ST-segment resolution with TIMI myocardial perfusion grade in acute myocardial infarction.

Background: More complete ST-segment resolution (ST res) in acute myocardial infarction (MI) has been associated with better epicardial and myocardial reperfusion as assessed with the Thrombolysis in Myocardial Infarction (TIMI) flow grade (TFG) and the TIMI myocardial perfusion grade (TMPG), respectively. However, no data exist comparing the speed of ST resolution on continuous electrocardiogram (ECG) monitoring with the TMPG on coronary angiography. We hypothesized that delayed ST res is associated with impaired TMPGs.
