INTRODUCTION: Lateral femoral cutaneous nerve (LFCN) injury is a risk specific to the direct anterior approach (DAA) for total hip arthroplasty (THA). However, prevention strategies have not been established. This study aimed to identify the predisposing factors determining LFCN injury during THA via a DAA. HYPOTHESIS: Patients with LFCN injury after THA via DAA would demonstrate predisposing factors. MATERIAL AND METHODS: LFCN injury was identified using a patient questionnaire...

We conducted a study to compare 90-day outcomes of patients who underwent simultaneous bilateral total hip arthroplasties (THAs) through the direct anterior (DA) approach (n = 19 patients) or the posterior approach (n = 21) over a 2-year period (2012-2014). Compared with patients in the posterior group, patients in the DA group had longer operative times (153 vs 106 min; P < .001) and longer anesthesia times (257 vs 221 min; P = .007) but were more likely to be discharged home (100.0% vs 71.4%; P = .02)...

BACKGROUND: Surgical approach is known as a risk factor that influences cup malposition while performing total hip arthroplasty (THA). However, no study has been conducted comparing cup positioning between the supine direct anterior (DA) and supine direct lateral (DL) THA approaches. QUESTIONS/PURPOSES: (1) Is there a difference in acetabular cup positioning between supine DA and supine DL THA approaches? (2) Are there differences in complications based on acetabular cup positioning between the two approaches? METHODS: From 2012 to 2014, 186 patients who underwent primary THAs using DA approach were matched with 186 patients using DL approach by body mass index, age, and gender...

BACKGROUND: The direct anterior approach (DAA) to the hip has been criticized as an approach that is limited to primary arthroplasty only. Our study objective was to demonstrate, in a cadaveric setting, that an alternate extension of the DAA can be used to reach the femur at the posterior border of the lateral vastus muscle without endangering the nerve supply. METHODS: The iliotibial tract is split anteriorly and pulled laterally, thereby opening the interval to the lateral-posterior aspect of the vastus muscle...

BACKGROUND: Allogeneic blood transfusions have inherent risk and direct cost in total hip arthroplasty. Anterior total hip arthroplasty has grown in popularity with increased utilization. This approach may offer an enhanced recovery but has been associated with increased blood loss. Several technologies have been developed including the Canady Hybrid Plasma Scalpel (CHPS) and Aquamantys Bipolar Sealer (BS) to decrease blood loss. METHODS: Two hundred forty-four consecutive patients undergoing anterior supine intermuscular total hip arthroplasty were separated by intraoperative cautery device (CHPS vs BS)...

Background and purpose - The length of stay after total hip arthroplasty has been reduced to 2-4 days after implementing fast-track surgery. We investigated whether a new time-based patient-centered primary direct anterior approach (DAA) total hip arthroplasty (THA) treatment protocol in a specialized clinic, with a planned length of stay of about 24 hours, could be achieved in all patients or only in a selected group of patients. Patients and methods - We analyzed prospectively collected data in a cohort of 378 consecutive patients who underwent a primary direct anterior THA as a patient-centered time-based procedure between March 1, 2012 and December 31, 2015...

BACKGROUND: Anterior column deficiency of the pelvis may pose a serious threat to the stability of the acetabular component after total hip arthroplasty and, thus, jeopardize the overall success of the procedure. METHODS: After Institutional Review Board approval, a retrospective review was undertaken to identify all patients undergoing revision total hip arthroplasty with anterior column augmentation through an extended direct anterior approach. Demographics and surgical details were collected, and subjects were followed for a 2-year minimum period to measure patient outcomes and to evaluate for the stability of construct fixation...

INTRODUCTION AND HYPOTHESIS: Some patients with hip osteoarthritis report that urinary incontinence (UI) is improved following total hip arthroplasty (THA). However, the type and severity of UI remain unclear. In this study, we hypothesize that both stress urinary incontinence (SUI) and urge urinary incontinence (UUI) are improved after THA. We assess the characteristics of UI and discuss the anatomical factors related to UI and THA for improved treatment outcome. METHODS: Fifty patients with UI who underwent direct anterior-approach THA were evaluated...

BACKGROUND: Radiographic outcomes after total hip arthroplasty (THA) have been linked to clinical outcomes. The direct anterior approach (DAA) for THA has been criticized by some for providing limited exposure and compromised implant position but allows for routine use of intraoperative fluoroscopy. We sought to determine whether radiographic measurements differed by THA approach using prospective cohorts. METHODS: Two reviewers blinded to surgical approach examined 194 radiographs, obtained 4-6 weeks after primary THA, and obtained measurements for acetabular inclination angle, acetabular anteversion, radiographic limb length discrepancy (LLD), and femoral offset...

BACKGROUND: Recently, the direct superior approach (DSA) has been introduced in total hip arthroplasty (THA) with the goal of limiting soft tissue dissection. This study's purpose was to use a visual pain diagram questionnaire to determine the location and severity of pain in patients undergoing THA via a DSA vs miniposterior approach (MPA). METHODS: This was a prospective, Institutional Review Board (IRB)-approved investigation from 3 centers. Patients aged 18-70 years with a diagnosis of osteoarthritis were included...

BACKGROUND: The direct anterior approach (DAA) is becoming more popular as the standard surgical approach for primary total hip arthroplasty. However, femoral complications of up to 2.8% have been reported. Therefore, it is important for surgeons to understand the periarticular neurovascular anatomy in order to safely deal with intraoperative complications. METHODS: Anatomic dissections were performed on 20 cadaveric hips. The neurovascular structures anterior to the femur and distal to the intertrochanteric line were dissected and its position was described in relation to anatomic landmarks easily identified through the DAA: anterior superior iliac spine (ASIS), the insertion of the gluteus minimus (GM), and the lesser trochanter (LT)...

BACKGROUND: Acetabulum positioning affects dislocation rates, component impingement, bearing surface wear rates, and need for revision surgery. Novel techniques purport to improve the accuracy and precision of acetabular component position, but may have a significant learning curve. Our aim was to assess whether adopting robotic or fluoroscopic techniques improve acetabulum positioning compared to manual total hip arthroplasty (THA) during the learning curve. METHODS: Three types of THAs were compared in this retrospective cohort: (1) the first 100 fluoroscopically guided direct anterior THAs (fluoroscopic anterior [FA]) done by a surgeon learning the anterior approach, (2) the first 100 robotic-assisted posterior THAs done by a surgeon learning robotic-assisted surgery (robotic posterior [RP]), and (3) the last 100 manual posterior (MP) THAs done by each surgeon (200 THAs) before adoption of novel techniques...

BACKGROUND: The United States spends $12 billion each year on ∼332,000 total hip arthroplasty (THA) procedures with the postoperative period accounting for ∼40% of costs. The purpose of this study was to evaluate the effect of surgical scheduling (day of week and start time) on clinical outcomes, hospital length of stay (LOS), and rate of nonhome discharge in THA patients. METHODS: Analysis of perioperative variables was performed for patients who underwent THA at an urban tertiary care teaching hospital from 2009 to 2014...

BACKGROUND: The direct anterior approach for total hip arthroplasty has recently gained interest for its quicker short-term recovery despite concerns about increased complications and operative time, especially during the steep learning curve period. The primary goal of this study was to determine if the transition from a posterior approach to a direct anterior approach for total hip arthroplasty can be achieved without harming patient safety. METHODS: This is a retrospective cohort single-surgeon study of consecutive primary total hip arthroplasties performed over a transition period from posterior to direct anterior (DA) approach...

BACKGROUND: The cumulative mid- to long-term risk of dislocation following total hip arthroplasty is considerably greater than has been reported in short-term studies. We retrospectively investigated the epidemiology of first-time dislocation following total hip arthroplasty using 28-mm heads through the direct anterior approach in patients with hip dysplasia who were followed up for more than 5 years. METHODS: The operative records of 871 hips in 790 consecutive patients were reviewed to determine the incidence of postoperative first-time dislocation...

BACKGROUND: The direct anterior approach (DAA) for total hip arthroplasty (THA) is typically performed in the supine position using a specially designed operating room table, which makes this approach more accessible to orthopedic surgeons. We attempted to perform this procedure in the lateral decubitus position on an ordinary operation table to avoid dependence on a special operating room table. There is an obvious absence of literature regarding this subject. METHODS: A total of 248 patients (295 hips) were recruited for primary THAs from July 1, 2014 to December 31, 2014...

A number of different software programs are used to investigate the in vivo wear of polyethylene bearings in total hip arthroplasty. With wear rates below 0.1mm/year now commonly being reported for highly cross-linked polyethylene (XLPE) components, it is important to identify the accuracy of the methods used to measure such small movements. The aims of this study were to compare the accuracy of current software programs used to measure two-dimensional (2D) femoral head penetration (FHP) and to determine whether the accuracy is influenced by larger femoral heads or by different methods of representing the acetabular component within radiostereometric analysis (RSA)...
