Aseptic Tibial Loosening is Associated with Thickness of the Cement: A Radiographic Case-Control Study.

Background: The cementation technique is crucial for achieving adequate fixation and optimal survivorship in total knee arthroplasty (TKA). The thickness of the cement at the tibial bone-implant surface may be related to aseptic tibial loosening. However, to date, no studies have demonstrated a direct association between cement thickness and rates of aseptic tibial loosening.

Does Surgical Approach Affect Dislocation Rate After Total Hip Arthroplasty in Patients Who Have Prior Lumbar Spinal Fusion? A Retrospective Analysis of 16,223 Cases.

Background: Lumbar spinal fusion (LSF) is a risk factor for dislocation following total hip arthroplasty (THA). The effect of the surgical approach on this association has not been investigated. This study examined the association between the surgical approach and dislocation following THA in patients who had prior LSF.

Revision rate following unipolar versus bipolar hemiarthroplasty.

Introduction: There has been much debate on use of bipolar or unipolar femoral heads in hemiarthroplasty for the treatment of femoral neck fractures. The outcome of these implants should be studied in the America Joint Replacement Registry (AJRR).

Methods: All primary femoral neck fractures treated with hemiarthroplasty between January 2012 and June 2020 were searched in the AJRR.

Cementing a Monoblock Dual-Mobility Implant into a Fully Porous Cup in Revision Total Hip Arthroplasty to Address Hip Instability: Surgical Technique.

Background: The use of a cemented monoblock dual-mobility implant into a fully porous cup is indicated for patients with acetabular bone loss who have a high risk of postoperative hip instability. Patients undergoing lumbar fusion for sagittal spinal deformities have an increased risk of hip dislocation (7.1%) and should be assessed on sitting and standing radiographs.

Salvage Options for the Failed Total Knee Arthroplasty.

Total knee arthroplasty (TKA) is one of the most popular and successful procedures of the past century. However, as the number of TKAs continues to increase, the volume of revision surgeries also will increase. Although revision TKAs are often successful, adult reconstruction surgeons will likely continue to see patients with limited arthroplasty options after multiple failed revision TKAs.

The Impact of Hospital Exposures Prior to Total Knee Arthroplasty on Postoperative Outcomes.

Background: Total knee arthroplasty (TKA) procedures are expected to grow exponentially in the upcoming years, highlighting the importance of identifying preoperative risk factors that predispose patients to poor outcomes. The present study sought to determine if preoperative healthcare events (PHEs) influenced outcomes following TKA.

Methods: This was a retrospective review of all patients who underwent TKA at a single institution from June 2011 to April 2022.

Giving and Receiving Meaningful Feedback in Orthopaedic Surgery Training.

The process of giving and receiving feedback in orthopaedic surgery training programs is distinctly unique from any other job. Trainees are required to meet certain milestones, and faculty are responsible for the caliber of surgical skills of their graduating trainees, yet there are rarely standardized practices and guidance for providing real-time feedback. Furthermore, institutional educational programs for faculty on giving meaningful feedback are lacking.

Staged Bilateral Total Hip Arthroplasty in a Patient With Larsen Syndrome.

Larsen syndrome is a rare genetic disorder characterized by weak connective tissues and various musculoskeletal abnormalities. This is a case report of a 39-year-old patient with Larsen syndrome who presented with over a decade of bilateral hip pain and difficulty ambulating. This patient has a prior history of bilateral congenital hip dislocations that were treated with open reduction and spica casting as a child with good result.

Return to Sport After Hip and Knee Arthroplasty: Counseling the Patient on Resuming an Active Lifestyle.

Purposeof Review: The purpose of this review is to summarize the available literature on the epidemiology, biomechanics, clinical outcomes, and complications of return to sport after TJA, as well as provide guidelines for patients' safe return to athletic activity.

Recent Findings: As volume and indications for total joint arthroplasty (TJA) expand, arthroplasty candidates today are demographically younger, more physically active, and have higher expectations for postoperative function. Many TJA patients wish to resume sports activity that may theoretically place their reconstruction under more biomechanical stress and risk for early wear or failure.

Staged Bilateral Total Hip Arthroplasty in a 17-Year-Old With Type VI Mucopolysaccharidosis.

Mucopolysaccharidosis encompasses multiple lysosomal storage disorders that are relevant to the orthopedic surgeon as they lead to disruption in bone and cartilage development. These patients may present with early-onset joint pain, including end-stage hip arthritis warranting total hip replacement. The altered hip anatomy in this disorder is of specific importance to the arthroplasty surgeon as it presents challenges when reconstructing the proximal femur and acetabulum and informs implant choice.

Emergency department visits following total joint arthroplasty: do revisions present a higher burden?

Aims: Although readmission has historically been of primary interest, emergency department (ED) visits are increasingly a point of focus and can serve as a potentially unnecessary gateway to readmission. This study aims to analyze the difference between primary and revision total joint arthroplasty (TJA) cases in terms of the rate and reasons associated with 90-day ED visits.

Methods: We retrospectively reviewed all patients who underwent TJA from 2011 to 2021 at a single, large, tertiary urban institution.

The direct anterior approach to the hip: a useful tool in experienced hands or just another approach?

The direct anterior approach (DAA) to the hip was initially described in the nineteenth century and has been used sporadically for total hip arthroplasty (THA). However, recent increased interest in tissue-sparing and small incision arthroplasty has given rise to a sharp increase in the utilization of the DAA. Although some previous studies claimed that this approach results in less muscle damage and pain as well as rapid recovery, a paucity in the literature exists to conclusively support these claims.

Tourniquet Use Is Associated With Reduced Blood Loss and Fewer Reoperations in Aseptic Revision Total Knee Arthroplasty.

Background: Although tourniquet use in primary total knee arthroplasty (TKA) has been widely studied, the outcomes associated with tourniquet use in revision TKA (rTKA) remains relatively unexplored. This study investigates surgical outcomes and patient satisfaction in association with tourniquet use during aseptic rTKA.

Methods: We retrospectively reviewed all patients who underwent rTKA for aseptic causes at our institution from 2011 to 2020.

Disparities Among Industry's Highly Compensated Orthopaedic Surgeons.

Unlabelled: The prosperous financial relationship between physicians and industry remains a highly scrutinized topic. Recently, a publicly available website was developed in conjunction with the U.S.

Chronicling the effect of COVID-19 on orthopedic literature.

Background: The novel coronavirus disease (COVID-19) has had a significant impact on orthopedic surgery practice, but there has been little investigation of the effects of COVID-19 on the orthopedic surgery literature. Additionally, because orthopedic research plays a vital role in physician education, changes to the characteristics and content of published literature can have lasting impacts on future teaching and learning. This paper represents the first known analysis of the COVID-19 pandemic's impact on peer-reviewed articles published in orthopedic surgery journals.

Presence of back pain prior total knee arthroplasty and its effects on short-term patient-reported outcome measures.

Purpose: Back pain may both decrease patient satisfaction after TKA and confound outcome assessment in satisfied patients. Our primary objective was to determine whether preoperative back pain is associated with differences in postoperative patient-reported outcome measures (PROMs).

Methods: We retrospectively reviewed 234 primary TKA patients who completed PROMs preoperatively and 12 weeks postoperatively, which included a back pain questionnaire, the Knee Injury and Osteoarthritis Outcome Score for Joint Replacement (KOOS JR) and the Forgotten Joint Score-12 (FJS-12).

Outcomes of surgical fixation of greater tuberosity fractures: A systematic review.

Background: Isolated greater tuberosity fractures account for up to a fifth of all proximal humeral fractures. There have been several retrospective cohort studies and case series reporting outcomes after treatment of this pathology. This study aims to report on the clinical outcomes of surgically treated isolated greater tuberosity fractures, as well as diagnostic workup and complications associated with fracture fixation.

Open Payments Reporting of Industry Compensation for Orthopedic Residents.

Objectives: Residents receiving industry payments are not legally required to be reported on the Centers for Medicare & Medicaid Services (CMS) Open Payments Database. The purpose of this study is to review reporting of orthopedic surgery residents and identify the trends for which payments or transfers in value were received.

Design: The CMS Open Payments Database was used to search for all available orthopedic residents from 2014 to 2016.

Association of State Legislation and Industry Compensation to Orthopaedic Residents: A 3-Year Review of the Centers for Medicare and Medicaid Services Open Payments Database.

Background: The Sunshine Act aims to increase the transparency of physicians receiving compensation from pharmaceutical and medical device companies. Nine states have supplementary legislation in addition to the Federal Sunshine Act. The purpose of this study is to assess the characteristics of financial compensation to orthopaedic residents on the Centers for Medicare and Medicaid Services (CMS) Open Payments Database in states with more restrictive regulations compared with those without additional restrictions.

Inhibition of COX-2 Pathway as a Potential Prophylaxis Against Arthrofibrogenesis in a Rabbit Model of Joint Contracture.

Arthrofibrosis is a common complication following total knee arthroplasty caused by pathologic fibroblast activation and excessive collagen deposition around a synovial joint leading to debilitating loss of motion. Treatment options are limited because the pathologic mechanisms remain to be characterized. Dysregulation of the inflammatory cascade may lead to communication between myofibroblasts and immune cells triggering tissue metaplasia, and excessive collagen deposition described clinically as arthrofibrosis.
