Aims: Traditionally, acetabular component insertion during total hip arthroplasty (THA) is visually assisted in the posterior approach and fluoroscopically assisted in the anterior approach. The present study examined the accuracy of a new surgeon during anterior (NSA) and posterior (NSP) THA using robotic arm-assisted technology compared to two experienced surgeons using traditional methods.
Methods: Prospectively collected data was reviewed for 120 patients at two institutions.
We sought to prospectively determine the efficacy of a noninvasive hemoglobin measurement system compared to a traditional blood draw in patients undergoing total joint arthroplasty. One hundred consecutive patients had their hemoglobin level measured by blood draw and the noninvasive device, simultaneously. Results were analyzed for the entire group and further stratified based on race and perfusion index measured by the device.

- Tears of the gluteus medius and minimus muscles are frequently blamed for chronic lateral hip pain in middle-aged people, often resulting from long-term degeneration.
- A rare case of an acute tear in a 78-year-old male marathon runner led to unsuccessful conservative treatment, prompting him to undergo surgery, which ultimately allowed him to return to his normal activities.
- Chronic injuries are more common than acute ones, with patients often misdiagnosed due to vague symptoms, including gradual lateral hip pain that worsens with certain movements.
Background: Obesity is routinely cited as a negative predictive factor for outcomes after total knee arthroplasty (TKA), but the direct mechanism responsible for this relationship has not been described. One possible explanation is a propensity for component malalignment in obese patients that is attributable to difficulty with surgical exposure.
Methods: This study evaluated the effect of obesity on TKA component alignment in 251 primary TKAs during a 12-month period at a single center in 2009.
Background: Diabetic patients undergoing total joint arthroplasty (TJA) with postoperative hyperglycemia >200 mg/dL have increased the risk of prosthetic joint infection (PJI). We investigated the correlation between preoperative hemoglobin A1c (A1c) and postoperative hyperglycemia in diabetic patients undergoing TJA.
Methods: A retrospective review of 773 diabetic patients undergoing TJA was conducted.
Objective: To characterize the relationship between stress and future risk of sepsis. We also evaluated the role of depression in this relationship.
Methods: We used population-based data on 30,183 participants in the Reasons for Geographic and Racial Differences in Stroke cohort, characterizing stress using the Perceived Stress Scale (PSS) and depressive symptoms using the Center for Epidemiologic Studies Depression Scale (CES-D).
