Purpose: We sought to systematically compare clinically significant differences between WC patients and their counterparts in relation to (1) functional outcomes, (2) complications, and (3) failure rates after hip arthroscopy.

Methods: We searched MEDLINE, EMBASE, and PubMed databases for studies published between January 1996 and February 2021.

Insulin dependence negatively impacts outcomes in anterior cervical discectomy with fusions: a 10-year retrospective analysis.

Background Context: Although anterior cervical discectomy and fusion (ACDF) procedures for cervical spine disease have been increasing amid a growing diabetic patient population, there is a paucity of literature focusing on insulin-dependence as a risk-factor for postoperative ACDF complications.

Purpose: To evaluate the differential impact of insulin dependence on perioperative outcomes including total length of stay, surgical, and medical complications within thirty days following ACDF.

Study Design/setting: A retrospective cohort, large multicenter database study.

Intraoperative Surgeon-Administered Adductor Canal Block Is a Safe Alternative to Preoperative Anesthesiologist-Administered Adductor Canal Block in Primary Total Knee Arthroplasty.

Background: The shift toward outpatient total knee arthroplasties (TKAs) has led to a demand for effective perioperative pain control methods. A surgeon-performed "low" adductor canal block ("low-ACB") technique, involving an intraoperative ACB, is gaining popularity due to its efficiency and early pain control potential. This study examined the transition from traditional preoperative anesthesiologist-performed ultrasound-guided adductor canal blocks ("high-ACB") to low-ACB, evaluating pain control, morphine consumption, first physical therapy visit gait distance, hospital length-of-stay, and complications.

Metal-on-metal (MoM) hip implants and pregnancy: are MoM implants good for mom?-a systematic review.

Metal-on-metal (MoM) bearing surfaces were historically used for young patients undergoing total hip arthroplasty (THA), and remain commonplace in modern hip resurfacing. A substantial number of female patients with MoM bearings subsequently gave birth following implantation of the bearings before a full understanding of metal ions exposure in these patients was established. In theory, it has been postulated that metal ions released from such implants may cross the placental barrier and cause harm to the fetus.

Cementless tapered wedge stems in patients undergoing primary total hip arthroplasty with Dorr C bone-are complication risks increased?

Background: The use of cementless femoral stems in patients undergoing primary total hip arthroplasty (THA) with Dorr C bone remains controversial for fear of fracture or subsidence. Purpose of this multicenter study was to compare clinical outcomes and complications of THA using a tapered femoral prosthesis in patients with Dorr C bone versus Dorr A/B bone.

Methods: A total of 1,030 patients underwent primary THA with a tapered wedge femoral stem at a minimum one year follow up.

A Reduction in Body Mass Index From ≥ 40 to < 40 Lowers Emergency Department Visits, but May Increase All-Cause Readmissions After Primary Total Hip Arthroplasty: Conflicting 90-Day Outcomes at a Single Institution.

Background: The American Association of Hip and Knee Surgeons tasked a 2013 workgroup to provide obesity-related recommendations in total joint arthroplasty. Morbidly obese patients (body mass index (BMI) ≥ 40) seeking hip arthroplasty were determined to be at increased perioperative risk, and surgeons were recommended to encourage these patients to reduce their BMI <40 presurgery. We report the effect of instituting a 2014 BMI <40 threshold on our primary total hip arthroplasties (THAs).

Institutional Adherence to the American Association of Hip and Knee Surgeons Body Mass Index Guidelines Lowers Perioperative Emergency Department Visits in Primary Total Knee Arthroplasty.

Background: In 2013, the American Association of Hip and Knee Surgeons tasked a workgroup to provide obesity-related recommendations in total joint arthroplasty and determined that patients who had body mass index (BMI) ≥ 40 seeking hip/knee arthroplasty were at increased perioperative risk and recommended preoperative weight reduction. Few studies have shown the actual results of instituting this; therefore, we reported the effect of instituting a BMI < 40 threshold in 2014 on our elective, primary total knee arthroplasties (TKAs).

Methods: We queried an institutional database to select all TKAs conducted from January 2010 to May 2020.

An Increase in Same-day Discharge After Total Joint Arthroplasty During the COVID-19 Pandemic Does Not Influence Patient Outcomes: A Retrospective Cohort Analysis.

Background: The coronavirus disease 2019 (COVID-19) pandemic caused major transitions in total joint arthroplasty (TJA), notably with the increased utilization of same-day discharge (SDD) pathways. This study assessed the effect of accelerated discharge pathways following the resumption of elective cases during the COVID-19 pandemic on SDD rates, adverse events, and characteristics associated with successful SDD following total hip and total knee arthroplasty.

Methods: This retrospective study split patients into cohorts: TJA prior to COVID-19 (pre-COVID, July 2019-December 2019) and TJA following the resumption of elective surgeries (post-COVID, July 2020-December 2020).

The association between perioperative blood transfusions and venous thromboembolism risk following surgical management of hip fractures.

Introduction: Despite high rates of transfusion reported among hip fracture patients in the perioperative period, the relationship between perioperative transfusions and VTE has not been thoroughly explored. Therefore, we used a national database to evaluate how perioperative transfusions among patients undergoing surgical management of hip fractures impacted 1) deep vein thrombosis (DVT) and 2) pulmonary embolism (PE) risk.

Methods: The Targeted Hip Fracture Database of the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) was queried for patients undergoing surgical management of hip fractures from 2016 to 2019.

Patients Who Undergo Rotator Cuff Repair Can Safely Return to Driving at 2 Weeks Postoperatively.

Background: Evidence-based guidelines are lacking for return to driving following rotator cuff repair (RCR). As a result, surgeons are often overly conservative in their recommendations, placing potential undue burden on patients and their families. Therefore, the primary objective of this study was to formulate evidence-based return-to-driving guidelines.

Clinical Outcomes and Survivorship of Hybrid Total Hip Arthroplasty Performed Through the Anterior Approach.

Introduction: There is growing evidence that cemented femoral stems have lower complication rates in the elderly due to lower rates of periprosthetic fracture. The main objective of this study was to analyze the survival rate of a hybrid total hip arthroplasty (THA) construct utilizing a taper-slip femoral stem implanted through the anterior approach (AA). Secondary outcome measures were the complication rate, the rate of aseptic loosening, coronal plane alignment of the stem, and the grade of the cement mantle.
