As quality measures may be increasingly used in knee surgery reimbursement, an important focus in outcome assessment will shift toward minimizing complications and increasing efficiency in knee arthroplasty reconstruction. The purpose of this study was to evaluate the efficacy of barbed, absorbable sutures in closure of the longitudinal surgical incision following knee arthroplasty, using post-operative complication occurrences. ⋯ Evaluation of overall primary outcomes showed a higher rate of wound complications using barbed sutures (P < 0.001). With increased rates of infection and overall closure related complications, this study shows that barbed suture use for superficial closure after knee arthroplasty should be avoided.

The Centers for Medicare and Medicaid Services has proposed bundling of payments for acute care episodes for certain procedures, including total joint arthroplasty. The purpose of this study is to quantify the readmission burden of TJA as a function of readmission rate and reimbursement for the bundled payment. ⋯ For each group, we determined 30-day readmission rates and direct costs of each readmission. The hospital cost margins for Medicare TJAs are small and any decrease in these margins can potentially make performing these procedures economically unfeasible potentially decreasing Medicare patient access.

The purpose of this study was to determine patients' survival after undergoing an early or delayed operation. We retrospectively assessed 1849 files of patients operated for proximal femoral fracture, divided into two diagnostic groups: intracapsular (n = 640) and extracapsular (n = 1209). 1163 (63%) were treated within 48 h from hospital admission and 686 (37%) were treated >48 h afterwards. ⋯ Males had a higher HR for mortality in both diagnostic groups. Early surgical intervention is beneficial for intra-capsular femoral fractures; male gender and a high ASA score are associated with an increased mortality hazard risk.

Randomized Controlled Trial
Topical administration of tranexamic acid in primary total hip and total knee arthroplasty.
Major blood loss is a known potential complication in total hip and total knee arthroplasty. We conducted a prospective, stratified, randomized, double-blind, placebo-controlled trial that evaluated 100 patients undergoing total knee or total hip arthroplasty to evaluate the effect on blood loss using the topical application of tranexamic acid. ⋯ Patients in the tranexamic acid group demonstrated an improved but non-significant reduction in the units of blood transfused compared to placebo (P = 0.423). There was no clinically significant increase in complications in the tranexamic acid group, including no incidence of venous thromboembolism.

In an attempt to preserve proximal femoral bone stock and achieve a better fit in smaller femora, especially in the Asian population, several new shorter stem designs have become available. We investigated the torque to periprosthetic femoral fracture of the Exeter short stem compared with the conventional length Exeter stem in a Sawbone model. ⋯ Results showed that Sawbone femurs break at a statistically significantly lower torque to failure with a shorter compared to conventional-length Exeter stem of the same offset. Both standard and short-stem designs are safe to use as the torque to failure is 7-10 times that seen in activities of daily living.
