We prospectively evaluated the degree of absolute agreement between measurements lateral center-edge angle (LCEA) on plain radiography (XR) and computed tomography (CT) in a consecutive cohort 205 patients (410 hips) undergoing hip arthroscopy. Preoperative LCEA were performed bilaterally utilizing standardized anteroposterior radiographs coronal reformatted CT scans. Demographic variables including age, gender, height, weight, BMI clinical diagnosis recorded for all patients. Overall,...

Background: Femoroacetabular impingement (FAI) and acetabular dysplasia lead to cartilage damage that commonly results in the chondral flaps seen during hip arthroscopy. Purpose: To compare flap morphology arthroscopy (“outside-in” vs “inside-out”) with clinical radiographic parameters underlying FAI dysplasia. Study Design: Cohort study; Level of evidence, 3. Methods: Patients who underwent by senior author between 2013 2017 a finding Outerbridge grade IV were included. Each procedure was...

Background: Prior reports of hip arthroscopy using a perineal post have established the risks groin soft tissue injury, sexual dysfunction, and altered lower extremity neurovascular function. These parameters not been investigated for without use post. Purpose: To evaluate effects postless on venous blood flow, nerve conduction, muscle damage, injury. Study Design: Case series; Level evidence, 4. Methods: Patients between ages 18 50 years undergoing an elective unilateral or simultaneous...

Background: The aims of this study were to describe a novel minimally invasive, interlocking periacetabular osteotomy (PAO) for the treatment hip dysplasia that was developed at our institution and report on its safety, complications, early clinical outcomes. Methods: This prospective longitudinal first 200 consecutive hips underwent CU (University Colorado) PAO, an combining benefits Birmingham pelvic (BIPO) Ganz PAO. technique provides direct visualization sciatic nerve during ischial...

Femoroacetabular impingement represents a common cause of hip pain in adolescents. The purpose the present study was to evaluate safety and efficacy simultaneous bilateral arthroscopy for symptomatic femoroacetabular adolescent athletes.Clinical data were collected prospective database on patients who underwent unilateral or included complications, reoperation rate, return play time. Differences International Hip Outcome Tool (iHOT)-12 scores according side postoperative follow-up time...

To investigate the correlation between femoroacetabular cartilage thickness and lateral acetabular coverage in patients undergoing hip arthroscopy for a variety of indications. Articular at is hypothesized to undergo adaptive change secondary unique patterns pathomechanical loading which results direct relationship thickness. A cohort 252 presenting our dedicated preservation service June 2013 2015 were retrospectively analysed. Preoperative radiographs MRI studies obtained all symptomatic...

Hyaluronic acid (HA) and leukocyte-poor platelet-rich plasma (LP-PRP) are 2 nonoperative treatment options that have been studied in patients with hip osteoarthritis (OA).To compare the efficacy of intra-articular injections low-molecular weight (LMW) HA LP-PRP OA.Randomized controlled trial; Level evidence, 1.A total 34 (36 hips) presenting signs OA were randomized to receive 3 blinded, weekly either or LMW-HA. Patients prospectively evaluated before at 6 weeks then 3, 6, 12, 24 months. The...

Symptomatic anterior instability of the hip is typically iatrogenic in nature and poses a challenging problem for orthopaedist. With early recognition, capsular repair plication are often effective restoring stability. Cases involving multiple episodes or those with delayed presentation, however, may have patulous deficient tissue precluding successful capsulorrhaphy. Capsular reconstruction play an important role stability these difficult cases. We present arthroscopic technique iliofemoral...

Aims The aim of this study was to evaluate the long-term clinical and radiographic outcomes Birmingham Interlocking Pelvic Osteotomy (BIPO). Patients Methods In prospective study, we report mid- first 100 consecutive patients (116 hips; 88 in women, 28 men) undergoing BIPO, reflecting surgeon’s learning curve. Failure defined as conversion hip arthroplasty. mean age at operation 31 years (7 57). Three (three hips) were lost follow-up. Results Survivorship 76% ten 57% a 17 years. Younger...

Ligamentum teres (LT) tears are increasingly being recognized as a source of pain and dysfunction in the hip. Although debridement for partial LT has long been established standard care with good relief, reconstruction successfully performed select patients to address concerns persistent symptomatic instability. The current technique femoral tunnel preparation carries added morbidity open dissection peritrochanteric space, an unnecessarily excessive bone removal, need very graft due distal...

Objectives: Acute compartment syndrome (ACS) is the result of decreased perfusion pressure (PP), and diagnosis frequently requires invasive monitoring. Our objective was to test a new noninvasive ultrasound device for correlating PP with measurements fascial displacement in controlled porcine model ACS. We hypothesized that experimental compartments impaired would be significantly greater than control normal baseline PP. Methods: ACS generated right anterior 7 anesthetized pigs,...
