Article Synopsis
  • Multimodal analgesia for total hip arthroplasty (THA) improves pain management and mobility while minimizing side effects compared to single-drug therapies.
  • The study compared local infiltration analgesia (LIA) and regional nerve blocks (RNBs) in a review of 1100 THA patients to evaluate their effectiveness within a multimodal pain management approach.
  • Results showed that while overall pain ratings were similar, the LIA group had significantly lower opioid usage, greater ambulation distances, higher same-day discharge rates, and fewer falls, indicating LIA might offer better functional outcomes.

Periprosthetic joint infections (PJI) are among the most morbid complications in total hip arthroplasty (THA). The ideal incubation time, however, for intraoperative cultures for PJI diagnosis remains unclear. As such, the aim of this study was to determine if any differences existed in culture-positive rates and organism detection between five-day and fourteen-day cultures.

Aims & Objectives: With modern advancements in surgical techniques and rapid recovery protocols, incidence of outpatient total joint arthroplasty (TJA) is increasing. Previous literature has historically focused on cost, safety, and clinical outcomes, with few studies investigating patient expectations and experiences. The aim of this study was to survey preoperative patient expectations related to outpatient TJA surgery compared with perioperative perceptions and experience.

Background: Radiographic predictors of outcomes associated with direct anterior approach (DAA) total hip arthroplasty (THA) are largely unknown. Anecdotally, some surgeons limit surgery to patients with low body mass index (BMI) or "favorable" bony morphology. Objective data on the impact of these factors is limited.

Background: Allograft prosthetic composites (APCs) have been used to perform revision total hip arthroplasty (THA) for massive femoral bone loss or deformity. Intussusception, or "telescoping", APC techniques have been proposed to enhance the contact area of this interface and provide superior mechanical fixation over conventional methods. The purpose of this study is to present to our knowledge, the largest series of telescoping APC THAs, along with surgical technique details and midterm (average 5-10 years) clinical results.

The vein of Galen malformation is caused by an abnormal shunting between choroidal arteries and the median prosencephalic vein during embryological development, leading to increased blood flow to the deep cerebral veins, intracranial damage, and systemic repercussions. Idiopathic spontaneous thrombosis of a vein of Galen malformation is rare, and its association with acute sinusitis has not been reported in the literature. We present the case of a girl with a postnatal diagnosis of a vein of Galen malformation at the age of 16 months, with secondary pulmonary hypertension that was adequately controlled with spironolactone.

Purpose: Cytochrome P450 2D6 (CYP2D6) genotype-guided opioid prescribing is limited. The purpose of this type 2 hybrid implementation-effectiveness trial was to evaluate the feasibility of clinically implementing CYP2D6-guided postsurgical pain management and determine that such an approach did not worsen pain control.

Methods: Adults undergoing total joint arthroplasty were randomized 2:1 to genotype-guided or usual pain management.

The purpose of this narrative review is to identify the anatomy and relevant blood supply to the femoral head as it pertains to hip arthroscopy and lateral cam morphology. The primary blood supply to the femoral head is the lateral ascending superior retinacular vessels, which are terminal branches of the medial femoral circumflex artery. These vessels penetrate the femoral head at the posterolateral head-neck junction.

Background: Tap test improves symptoms of idiopathic normal pressure hydrocephalus (iNPH); hence, it is widely used as a diagnostic procedure. However, it has a low sensitivity and there is no consensus on the parameters that should be used nor the volume to be extracted. We propose draining cerebrospinal fluid (CSF) during tap test until a closing pressure of 0 cm H2O is reached as a standard practice.

Accelerated physical therapy (PT) protocols are a potential mechanism for achieving early mobilization and safe discharge from hospital after elective primary total hip arthroplasty (THA) or total knee arthroplasty (TKA). We compared 2 groups of patients who underwent elective unilateral THA or TKA-those who started PT the same day (Day 0) and those who started PT the next day (Non-Day 0). The difference in mean (SD) hospital length of stay between the Day 0 and Non-Day 0 groups was not statistically significant for THA patients, 2.

Femoroacetabular impingement (FAI) is a common cause of hip pain, and when indicated, can be successfully managed through open surgery or hip arthroscopy. The goal of this review is to describe the different approaches to the surgical treatment of FAI. We present the indications, surgical technique, rehabilitation, and complications associated with (1) open hip dislocation, (2) reverse periacetabular osteotomy, (3) the direct anterior "mini-open" approach, and (4) arthroscopic surgery for FAI.

Background: Although highly porous metals have demonstrated excellent bone ingrowth properties and so are an intriguing option for fixation in total knee arthroplasty (TKA), some surgeons are skeptical about the durability of uncemented tibial fixation and the potential for soft tissues to adhere to these porous metals and perhaps cause knee stiffness or pain.

Questions/purposes: The purpose of this study was to compare, in the context of a randomized clinical trial, a highly porous metal tibia compared with a traditional modular cemented tibia in terms of survivorship, Knee Society scores, range of motion (ROM), and complications.

Methods: From 2003 to 2006, 397 patients (age 67.

Background: Anemia is common in patients undergoing total joint arthroplasty (TJA). Numerous studies have associated anemia with increased risk of infection, length of hospital stay, and mortality in surgical populations. However, it is unclear whether and to what degree preoperative anemia in patients undergoing TJA influences postoperative periprosthetic joint infection (PJI) and mortality.

Fibromyalgia has recently emerged as a diagnosis of exclusion for patients with chronic, widespread pain. We investigated the influence of this comorbidity on outcomes of total knee arthroplasty (TKA). We matched 59 patients (90 knees) who underwent primary TKA with a diagnosis of fibromyalgia to control patients who underwent the same surgery.

Article Synopsis
  • Metabolic syndrome is defined by the presence of at least three out of four criteria: obesity, dyslipidemia, hypertension, and diabetes, and is associated with significant cardiovascular risks.
  • Patients with metabolic syndrome undergoing total joint arthroplasty (TJA) were found to have a notably higher risk of cardiovascular complications compared to those without the syndrome (P = .017).
  • The likelihood of experiencing adverse events increased by 29% with three components and by 32% with all four components of metabolic syndrome present, suggesting a cumulative effect that raises overall risk during surgical procedures.
