Hip replacement

OBJECTIVE: To describe the implementation, feasibility and safety of a day-stay joint replacement pathway in a regional public hospital in Australia. METHOD: Over a 12-month pilot period, a prospective descriptive analysis of consecutive patients undergoing total knee and hip arthroplasty was conducted. The number of eligible day-stay patients, proportion of successful same-day discharges and reasons for same-day failure to discharge were recorded. Outcome measures captured for all joint replacements across this period included length of stay (LoS), patient reported outcomes, complications and patient satisfaction...

PURPOSE: The association between preoperative mental health and immediate postoperative ambulation in primary Total Joint Arthroplasty (TJA) has sparsely been studied. Thus, this study's objective was to investigate the association between mental health (measured by the Mental Component Score (MCS) from the Veterans RAND 12 (VR-12)) and peri-operative metrics. METHODS: We conducted a retrospective study of patients who underwent primary TJA and completed a VR-12 questionnaire between January 2018 and June 2023 at a single academic hospital...

49,XXXYY is an extremely rare sex chromosomal aneuploidy (SCA), with only seven cases reported worldwide to date. Among these cases, only three have been documented into adulthood. Moreover, no cases of 49,XXXYY have been reported in Japan. This SCA has been identified in two scenarios: in vitro fertilization and abortion. Similar to 47,XXY, this aneuploidy is a type of Klinefelter syndrome. Aneuploidy of the X chromosome can lead to various progressive complications due to excess X chromosomes. Herein, we present the case of a Japanese man with 49,XXXYY...

OBJECTIVES: Prosthetic joint infection (PJI) is a serious complication following total hip arthroplasty (THA) entailing increased mortality, decreased quality of life and high healthcare costs.The primary aim was to investigate whether the national project: Prosthesis Related Infections Shall be Stopped (PRISS) reduced PJI incidence after primary THA; the secondary aim was to evaluate other possible benefits of PRISS, such as shorter time to diagnosis. DESIGN: Cohort study...

OBJECTIVES: Acute postsurgical pain (APSP) may persist over time and become chronic. Research on predictors for APSP and chronic postsurgical pain (CPSP) has produced inconsistent results. This observational study aimed to analyze psychological and psychophysical variables associated with APSP and CPSP after total knee or hip arthroplasty, and to explore the role of sex. METHODS: Assessments were conducted before surgery, 48 h, and 3 months postsurgery, including questionnaires (sociodemographic, pain related, and psychological) and quantitative sensory testing (QST)...

INTRODUCTION: Progressive pseudorheumatoid dysplasia is a rare autosomal recessive disorder caused by a mutation in the Wnt1-inducible signaling protein 3 gene, with few cases reported. CASE REPORT: We discuss the case of a 19-year-old Caucasian male patient with polyarticular involvement, including shoulders, elbows, wrists, hands, spine, hips, knees, and notably the ankles. Despite a well-conducted medical treatment, due to the rapid progression of his condition, the patient underwent bilateral total hip and knee arthroplasties, as well as left ankle replacement...

This editorial explores the impact of bundled payment initiatives, specifically in the context of orthopedic surgery, on access to care. We examine the phenomenon of "cherry picking" healthier patients and "lemon dropping" higher-risk patients, potentially leading to disparities in access and healthcare outcomes. We discuss recent studies investigating these concerns and highlight the need for more in-depth research to better understand the groups these policies may marginalize. Policymakers are urged to consider measures to protect disadvantaged patients and ensure equitable access to care, aligning with the principles of equality and diversity in healthcare...

BACKGROUND: Acute kidney injury (AKI) is associated with increased complications after total hip arthroplasty (THA) and total knee arthroplasty (TKA). The purpose of this study was to determine the risk factors for AKI after THA and TKA and evaluate if preoperative use of antihypertensive drugs is a risk factor for AKI. METHODS: A retrospective review of 7406 primary TKAs and THAs (4532 hips and 2874 knees) from 2013 to 2019 was performed. The following preoperative variables were obtained from medical records: medications, chemistry 7 panel, Elixhauser comorbidities, and demographic factors...

BACKGROUND: Since the early 2000s, the National Health Service (NHS) in England has expanded provision of publicly funded care in private hospitals as a strategy to meet growing demand for elective care. This study aims to compare patient outcomes, efficiency and adverse events in private and NHS hospitals when providing elective hip and knee replacement. METHODS: We conducted a population-based cohort study including patients ≥18 years, undergoing a publicly funded elective hip or knee replacement in private and NHS hospitals in England between January 1st 2016 and March 31st 2019...

BACKGROUND: The associations between ultra-processed food (UPF) consumption, genetic susceptibility, and the risk of osteoarthritis (OA) remain unknown. This study was to examine the effect of UPF consumption, genetic susceptibility, and their interactions on hip/knee OA. METHODS: Cohort analyses included 163,987 participants from the UK Biobank. Participants' UPF consumption was derived from their 24-h dietary recall using a questionnaire. Genetic risk scores (GRSs) of 70 and 83 single nucleotide polymorphisms (SNPs) for hip and knee OA were constructed...

Periprosthetic joint infection is a feared complication after the megaprosthetic reconstruction of oncologic and non-oncologic bone defects of including the knee or hip joint. Due to the relative rarity of these procedures, however, optimal management is debatable. Considering the expanding use of megaprostheses in revision arthroplasty and the high revision burden in orthopedic oncology, the risk of PJI is likely to increase over the coming years. In this non-systematic review article, we present and discuss current management options and the associated results focusing on studies from the last 15 years and studies from dedicated centers or study groups...

Background : Even minor adverse reactions after total hip replacement (THR), including lymphedema, postoperative leg swelling, and blood loss, compromise patient comfort in times of minimally invasive fast-track surgery. Compression dressings are commonly used in surgical practice to reduce swelling or blood loss. However, the use of spica hip compression dressings after primary THR is controversial, and prospective studies are lacking. Methods: We conducted a prospective, single-center, two-arm, randomized controlled trial (RCT) of patients undergoing THR for primary osteoarthritis...

Pericapsular nerve group (PENG) block and periarticular injection (PAI) provide motor-sparing analgesia following hip surgery. We hypothesized that PAI offers non-inferior pain relief compared with PENG block in patients undergoing primary total hip arthroplasty (THA). In this randomized trial, 66 patients who underwent primary THA under spinal anesthesia were assigned to the PENG or PAI groups. The primary endpoint was the resting pain score 24 h postoperatively. The secondary endpoints included pain scores at rest and during movement at 6 and 48 h postoperatively, quadriceps strength at 24 h postoperatively, and opioid consumption at 24 and 48 h postoperatively...

In current-generation designs of total primary hip joint replacement, the prostheses are fabricated from alloys. The modulus of elasticity of the alloy is substantially higher than that of the surrounding bone. This discrepancy plays a role in a phenomenon known as stress shielding, in which the bone bears a reduced proportion of the applied load. Stress shielding has been implicated in aseptic loosening of the implant which, in turn, results in reduction in the in vivo life of the implant. Rigid implants shield surrounding bone from mechanical loading, and the reduction in skeletal stress necessary to maintain bone mass and density results in accelerated bone loss, the forerunner to implant loosening...

Hypothyroid myopathy is uncommon in childhood. Severe hypothyroid myopathy observed in paediatric practice is a part of Kocher-Debré-Semelaigne syndrome (KDSS, OR-PHA:2349), a rare disorder characterised by muscular pseudohypertrophy and long-standing moderate-to-severe hypothyroidism. We present a pubertal girl with KDSS diagnosed with severe myopathy and significantly limited mobility and progressively increasing pains in the lumbar area, hip joints, and the lower limbs. Additionally, the patient presented metabolic syndrome with severe obesity, growth retardation, and educational difficulties...

An enlarged iliopectineal bursa (IB) can cause pressure on iliofemoral veins. Clinical presentation can manifest as asymmetrical lower extremity edema. This case report demonstrates extensive asymmetrical leg edema caused by femoral vein compression based on iliopectineal bursitis (IB-itis) associated with advanced osteoarthritis (OA) of the left hip joint with an outline of relevant current literature. A female patient presented with left hip pain and edema in the leg. X-ray showed severe OA of the left hip...

Liner dissociations are rare but catastrophic complications after THA, requiring revision surgery. Although this complication has been well documented in THA with modular components, it has been rarely described in preassembled designs. In this report we present a rare case of liner dissociation in a ceramic-on-ceramic pre-assembled cup design. A 41-year-old man who received THA seven years ago, presented with sudden pain in the hip. Radiographic examination confirmed a small dissociation of the liner component in the acetabular shell, as well as radiolucency between the acetabular shell and the ceramic liner, and pneumarthrosis...

This case report describes a single patient with recurrent implant fractures of his left total hip replacement. According to our knowledge this is the first patient in literature with recurrent implant fractures. This is a rare phenomenon as reason for revision. Risk factors for implant failure of total hip replacement include a lack of proximal support, a distally well fixed stem with proximal debonding, malalignment of the stem and raised BMI.

The introduction of fast-track protocols decreased length of hospital stay and improved rehabilitation and outcomes in total joint arthroplasty. Despite improved clinical results published in many papers, the patient perspective of these protocols is less investigated. Purpose of this study was to explore the patient perspective of fast-track protocols in arthroplasty. A systematic search for articles of patient experiences in total hip, knee, and shoulder arthroplasty was conducted using EMBASE, MEDLINE, Cochrane, and Web-of-Science for articles published from inception to February 14, 2023...

Chronic pain and functional limitations caused by coxarthrosis are important factors in the onset of depression, as there are higher rates of depression in this group of patients than in the general population. Total hip arthroplasty (THA) has been shown to decrease pain and improve function in these patients, which may positively influence the patient's depressive symptoms. The objectives of the study are to evaluate the differences between patients with depression and patients without depression in the immediate postoperative period (pain and hospitalization time) and to evaluate functional outcomes one year after surgery...
