Tibiofemoral Contact Mechanics with Horizontal Cleavage Tear and Resection of the Medial Meniscus in the Human Knee.
The meniscus is known to increase the contact area and decrease contact pressure in the tibiofemoral compartments of the knee. Radial tears of the meniscal root attachment along with partial resections of the torn meniscal tissue decrease the contact area and increase pressure; however, there is a lack of information on the effects of a horizontal cleavage tear (HCT) and partial leaf meniscectomy of such tears on tibiofemoral contact pressure and contact area. ⋯ Repair or minimal resection of meniscal tissue of an HCT may be preferred to complete leaf resection to maintain knee tibiofemoral contact mechanics.

Comparative StudySafety and Outcomes of Inpatient Compared with Outpatient Surgical Procedures for Ankle Fractures.
As the cost of health-care delivery rises in the era of bundled payments for care, there is an impetus toward minimizing hospitalization. Evidence to support the safety of open reduction and internal fixation (ORIF) of ankle fractures in the outpatient setting is largely anecdotal. ⋯ Therapeutic Level III.

Coagulation Profile of Patients with Adolescent Idiopathic Scoliosis Undergoing Posterior Spinal Fusion.
Blood loss and transfusion requirements during posterior spinal fusion for adolescent idiopathic scoliosis remain a concern. The mechanism of bleeding in these patients is poorly characterized. Thromboelastography is a comprehensive test of a patient's coagulation system commonly used in cardiac surgical procedures. It has not been well studied for use in patients with adolescent idiopathic scoliosis. ⋯ The stress of posterior spinal fusion induces a hypercoagulable state in patients with adolescent idiopathic scoliosis. Over the first 2 hours of a surgical procedure, varying degrees of fibrinolysis develop. Platelets and coagulation factors are not depleted. Our data support the use of antifibrinolytic therapy for patients with adolescent idiopathic scoliosis.

ReviewInconsistencies Between Physician-Reported Disclosures at the AAOS Annual Meeting and Industry-Reported Financial Disclosures in the Open Payments Database.
The purpose of this study was to determine the rate and type of inconsistencies between disclosures self-reported by physicians at a major academic meeting in the United States and industry-reported disclosures in the Open Payments database for a concordant time period. ⋯ In this sample, there was a 35% rate of inconsistency between physician-reported financial relationships for presenters at the AAOS Annual Meeting and industry-reported relationships published in the Open Payments database.

Five-Year Survival of 20,946 Unicondylar Knee Replacements and Patient Risk Factors for Failure: An Analysis of German Insurance Data.
Improvements in implant design and surgical technique of unicondylar knee arthroplasty have led to reduced revision rates, but patient selection seems to be crucial for success of such arthroplasties. The purpose of the present study was to analyze the 5-year implant survival rate of unicondylar knee replacements in Germany and to identify patient factors associated with an increased risk of revision, including >30 comorbid conditions. ⋯ Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.
