Purpose: A relatively high expense with any procedure is total operative time; two components being the time spent anesthetizing the patient and time spent transferring the patient out of the operating room (OR). Both times can be affected by the anesthetic method used. This study compares different operative time intervals for both spinal anesthesia (SA) and general anesthesia (GA), in patients undergoing a primary total hip arthroplasty (THA), to identify the most appropriate and cost-effective anesthetic method.

Objectives: The number of revision total knee arthroplasty (TKA) procedures continues to rise, a direct consequence of the increase in primary TKA. The number of arthroplasty-trained orthopaedic surgeons has failed to increase at a corresponding rate, and the increased burden will ultimately fall on non-specialized orthopaedists. Resident involvement in primary TKA has not been found to increase postoperative complications, but revision TKA is more complex and the impact of resident involvement has not been well studied.

Introduction: Human immunodeficiency virus (HIV) positive patients are at high risk for osteonecrosis along with age-related osteoarthritis, resulting in a high number of joint reconstruction surgeries at younger ages in these immunosuppressed patients. Few previous studies have reported on patient outcomes in HAART (highly active antiretroviral therapy) compliant patients undergoing primary arthroplasty. The aim of this study is to report one institution's overall rate of complications and revision in HAART-compliant patients after primary hip and knee arthroplasty.

Background: The type of anesthesia used in total knee arthroplasty is one modifiable factor that could save hospital systems time and money. With spinal and general anesthesia having similar outcomes, more weight can be placed on these anesthesia methods' time or money-saving aspects.

Objective: This study aims to determine the differences in time expenditure between spinal and general anesthesia for total knee arthroplasty to optimize OR efficiency and reduce costs.

Objectives: The effects of the novel coronavirus on the musculoskeletal system have been reported with wide variability. The purpose of this study was to determine the prevalence of musculoskeletal symptoms and if these correlated with other patient characteristics.

Methods: This was a retrospective review of 685 admitted patients who were found to be positive for COVID-19 during their admission.

Severe cases of acetabular fractures are complicated, leading to further damage to the femoral head and post-traumatic osteoarthritis (PTOA). These adverse events eventually lead to complexities in the management of patients with the aforementioned conditions. Total hip arthroplasty (THA) is a surgical option for improving both stability and functionality, and for controlling pain in patients with PTOA.

We present a unique case of a 56-year-old male patient who ambulated on a hip cement spacer for 11 years. After hemiarthroplasty after a motor vehicle accident, the patient developed periprosthetic joint infection (PJI) several years later, and underwent stage-1 revision. With the resolution of the infection after stage 1, the patient refused the second stage due to satisfaction with the cement spacer for nearly 11 years.

It is not common to encounter arteriovenous malformations (AVMs) during total hip arthroplasty (THA). We report the present case to draw attention to the possibility of an AVM during the direct anterior approach (DAA) for THA, which, if not borne in mind, may lead to the myriad of complications related to excessive bleeding. An 81-year-old female presented to the emergency department with a left femoral neck fracture.

 The aim of the present study was to determine the influence of resident involvement on acute complication rates in revision total hip arthroplasty (THA).  Using the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database, 1,743 revision THAs were identified from 2008 to 2012; 949 of them involved a resident physician. Demographic information including gender and race, comorbidities including lung disease, heart disease and diabetes, operative time, length of stay, and acute postoperative complications within 30 days were analyzed.
