The Journal of Hip Surgery DOI: 10.1055/s-0044-1781435 Total hip arthroplasty (THA) in the setting of significant retained femoral instrumentation or complex proximal femoral deformity may be challenging and published reports of THA in this setting reveal sobering results. Hip resurfacing arthroplasty (HRA) is an alternative to THA and may avoid complex hardware removal or deformity correction at the time of hip arthroplasty. Twenty-three patients who underwent elective HRA in the setting of significant proximal femoral deformity and/or retained femoral instrumentation were identified from a p ..read more

The Journal of Hip Surgery DOI: 10.1055/s-0044-1781433 The prevalence of obesity is significantly increasing in the U.S. population and is associated with both increased incidence of total hip arthroplasty (THA) and potentially worsened postoperative outcomes. Current guidelines strongly encourage exercise-based weight loss in morbidly obese THA candidates to decrease patient risk profiles, but data on the impact of receiving bariatric surgery (BS) for weight loss prior to THA are limited and controversial. The purpose of this study was to clarify the impact of BS on postoperative complication ..read more

The Journal of Hip Surgery DOI: 10.1055/s-0044-1781434 Periprosthetic joint infection (PJI) is one of the most severe complications following total hip arthroplasty (THA), and identifying factors associated with PJI is vital for preoperative risk stratification. The aim of this study was to compare risk of PJI after THA across insurance payers using a statewide health data registry. A retrospective review was conducted querying the New York Statewide Planning and Research Cooperative System for all patients undergoing elective unilateral primary THA using International Classification of Diseas ..read more

The Journal of Hip Surgery DOI: 10.1055/s-0043-1778087 Previous reports have investigated the correlation between time to revision total hip arthroplasty (rTHA) and reason for revision, but little is known regarding the impact of timing on outcomes following rTHA. The purpose of this study is to evaluate the effect of time to rTHA on outcomes following rTHA. This retrospective observational study reviewed patients who underwent unilateral, aseptic rTHA at an academic orthopaedic hospital between June 2011 and April 2020 with at least 1-year of follow-up. Patients were categorized as early revi ..read more

The Journal of Hip Surgery DOI: 10.1055/s-0043-1778088 Though opioids can be very effective for postoperative pain management after revision total hip arthroplasty (rTHA), many physicians have made an effort to decrease usage of these medications by focusing on alternative pain management strategies to reduce opioid dependence and unwanted side effects. This study sought to investigate trends in opioid consumption during hospitalization following rTHA from 2016 to 2021. We retrospectively reviewed all patients who received rTHA from January 2016 to April 2021. Baseline demographic variables in ..read more

The Journal of Hip Surgery DOI: 10.1055/s-0043-1777061 Hip hemiarthroplasty (HA) remains a frequently performed surgery for femoral neck fractures especially in the oldest, lowest demand patients. Debate persists concerning the optimal choice between unipolar and bipolar HA implants. A rare but important to recognize complication unique to bipolar HA is intraprosthetic dissociation (IPD). We review the literature on this rare phenomenon and identify predominant etiologies and implant components most involved in IPD, notably the role of hip dislocation and closed reduction in precipitating this ..read more

The Journal of Hip Surgery DOI: 10.1055/s-0043-1777064 Hip valgus osteotomy for femoral neck nonunion is a widely popular procedure with high success rates. In the setting of multiply injured patients, with concomitant femoral neck and shaft fractures, a potentially higher incidence of femoral neck nonunion rates may call for a hip valgus osteotomy in the presence of an existing retrograde intramedullary nail, which has not been reported in literature. We revisit the preoperative planning and describe the surgical technique of hip valgus osteotomy in a case of a nonunion of a femoral neck frac ..read more

The Journal of Hip Surgery DOI: 10.1055/s-0043-1777065 The minimum clinically important difference (MCID) of an orthopaedic outcome measure is commonly used to assess treatment success including for patients undergoing total hip arthroplasty (THA). Various patient factors may contribute to MCID values in patients undergoing THA. The purpose of this study was to calculate the 1-year MCID for the Hip Disability and Osteoarthritis Outcome Score for Joint Replacement (HOOS-JR) based on patient factors and evaluate if there were any differences between each cohort's MCID.A patient-reported outcome ..read more

The Journal of Hip Surgery DOI: 10.1055/s-0043-1777060 Achieving femoral stem stability in complex primary and revision total hip arthroplasty (rTHA) cases is a challenging goal that monoblock fluted titanium tapered stems (FTTS) were designed to address. However, as more modern FTTS are developed, there are still questions regarding outcomes for these stems. The purpose of this study is to determine the radiographic and clinical outcomes of a modern monoblock FTTS. A multicenter retrospective observational study examined the hip databases of three institutions to obtain all monoblock FTTS wit ..read more

The Journal of Hip Surgery DOI: 10.1055/s-0043-1777062 The U.S. health care system continues to absorb greater costs for total hip arthroplasty (THA). The purpose of this study is to quantify inpatient charges for primary THA (pTHA) and revision THA (rTHA) and to review trends over the past decade. A New York statewide database was utilized to identify all inpatient elective pTHA and rTHA from 2010 to 2020. Nonelective indications were excluded. The primary outcome measure was total inpatient charges per encounter. Secondary outcomes included: accommodation charges, ancillary charges, and hosp ..read more
