Evaluation and Management of the Athlete's Hip.

Hip and groin pain is common in athletes, and there are many possible underlying pathologies. It is important to describe athletic hip pathology in the context of sport-specific physiologic loads and biomechanical demands. Three distinct types of athletes with this pathology are collision athletes, hypermobility athletes, and endurance athletes.

Time-Driven Activity-Based Costing Analysis Identifies Use of Consumables and Operating Room Time as Factors Associated With Increased Cost of Outpatient Primary Hip Arthroscopic Labral Repair.

Purpose: To use time-driven, activity-based costing (TDABC) methodology to investigate drivers of cost variation and to elucidate preoperative and intraoperative factors associated with increased cost of outpatient arthroscopic hip labral repair.

Methods: A retrospective analysis of data from January 2020 to October 2021 was performed. Patients undergoing primary hip arthroscopy for labral repair in the outpatient setting were included.

Open and arthroscopic management of femoroacetabular impingement: a review of current concepts.

Femoroacetabular impingement (FAI) is a common femoral and/or acetabular abnormality that can cause progressive damage to the hip and osteoarthritis. FAI can be the result of femoral head/neck overgrowth, acetabular overgrowth or both femoral and acetabular abnormalities, resulting in a loss of native hip biomechanics and pain upon hip flexion and rotation. Radiographic evidence can include loss of sphericity of the femoral neck (cam impingement) and/or acetabular retroversion with focal or global overcoverage (pincer impingement).

Core Muscle Injury: Evaluation and Treatment in the Athlete.

Background: Pain in the groin region, where the abdominal musculature attaches to the pubis, is referred to as a "sports hernia,""athletic pubalgia," or "core muscle injury" and has become a topic of increased interest due to its challenging diagnosis. Identifying the cause of chronic groin pain is complicated because significant symptom overlap exists between disorders of the proximal thigh musculature, intra-articular hip pathology, and disorders of the abdominal musculature.

Purpose: To present a comprehensive review of the pathoanatomic features, history and physical examination, and imaging modalities used to make the diagnosis of core muscle injury.

Bilateral hip arthroscopy for treating femoroacetabular impingement: a systematic review.

Purpose: Femoroacetabular impingement (FAI) is a hip disorder which can often present bilaterally. The purpose of this systematic review was to explore the current practices for bilateral hip arthroscopy in treating FAI as they relate to outcomes and complications.

Methods: This review has been conducted according to the guidelines of Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA).

Hip Instability in Ballet Dancers: A Narrative Review.

Dancers possess a large degree of hip range of motion that results from a combination of innate and acquired osseous morphology and permissive soft tissues. Generalized hypermobility in dancers may predispose them to a spectrum of hip instability. The objective of this narrative review is to discuss the anatomical characteristics, pathogenesis, risk factors, clinical signs and symptoms, management, and outcomes of hip instability treatments in dancers.

The Prevalence of Cam Morphology: A Cross-Sectional Evaluation of 3,558 Cadaveric Femora.

We sought to determine (1) the prevalence of cam deformity in the population and that of bilateral cam deformity, (2) the typical location of a cam lesion, and (3) the typical size of a cam lesion by direct visualization in cadaveric femora. Two observers inspected 3,558 human cadaveric femora from the Hamann-Todd Osteological Collection from the Cleveland Museum of Natural History. Any asphericity >2 mm from the anterior femoral neck line was classified as a cam lesion.

Does Time From Injury to Surgery Affect Outcomes After Surgical Repair of Partial and Complete Proximal Hamstring Ruptures?

Background: No previous study has compared the outcomes of repair for partial and complete proximal hamstring ruptures at various intervals after the injury.

Purpose: The primary aim was to determine whether time from injury to surgery affected outcomes after primary repair of partial and complete proximal hamstring ruptures. The secondary aim was to assess patients' experiences from initial evaluation to finding a treating surgeon.

Ability to return to work without restrictions in workers compensation patients undergoing hip arthroscopy.

The purpose of this study was to investigate the ability of worker's compensation (WC) patients to return to work without restrictions after hip arthroscopy. Twenty-nine WC patients along with age and gender matched controls who underwent hip arthroscopy were retrospectively reviewed after achieving maximum medical improvement (MMI) status at minimum 1 year postoperatively. Patient demographic factors were evaluated, along with the Hip Outcome Score Activities of Daily Living and Sports-Specific subscales, and the modified Harris Hip Score (mHHS).

The Effect of Capsulotomy and Capsular Repair on Hip Distraction: A Cadaveric Investigation.

Purpose: To quantify how increasing interportal capsulotomy size affects the force required to distract the hip and to biomechanically compare simple side-to-side suture repair to acetabular-based suture anchors as capsular repair techniques.

Methods: Twelve fresh-frozen cadaveric hip specimens were dissected to the capsuloligamentous complex of the hip joint and fixed in a material testing system, such that a pure axial distraction of the iliofemoral ligament could be achieved. After each hip in was tested an intact state, sequential distraction was tested with 2, 4, 6, and 8 cm capsulotomies.

Capsulotomy Size Affects Hip Joint Kinematic Stability.

Purpose: To evaluate the effect of capsulotomy size and subsequent repair on the biomechanical stability of hip joint kinematics through external rotation of a cadaveric hip in neutral flexion.

Methods: Eight fresh-frozen cadaveric hip specimens were used in this study. Each hip was tested under torsional loads of 6 N·m applied by a servohydraulic frame and transmitted by a pulley system.

The Natural History of Femoroacetabular Impingement.

Femoroacetabular impingement (FAI) is a clinical syndrome resulting from abnormal hip joint morphology and is a common cause of hip pain in young adults. FAI has been posited as a precursor to hip osteoarthritis (OA); however, conflicting evidence exists and the true natural history of the disease is unclear. The purpose of this article is to review the current understanding of how FAI damages the hip joint by highlighting its pathomechanics and etiology.

Sonographic prevalence of groin hernias and adductor tendinopathy in patients with femoroacetabular impingement.

Background: Femoroacetabular impingement (FAI) is a common debilitating condition that is associated with groin pain and limitation in young and active patients. Besides FAI, various disorders such as hernias, adductor tendinopathy, athletic pubalgia, lumbar spine affections, and others can cause similar symptoms.

Purpose: To determine the prevalence of inguinal and/or femoral herniation and adductor insertion tendinopathy using dynamic ultrasound in a cohort of patients with radiographic evidence of FAI.

Labral reconstruction with iliotibial band autografts and semitendinosus allografts improves hip joint contact area and contact pressure: an in vitro analysis.

Background: Labral reconstruction using iliotibial band (ITB) autografts and semitendinosus (Semi-T) allografts has recently been described in cases of labral deficiency.

Purpose/hypothesis: To characterize the joint biomechanics with a labrum-intact, labrum-deficient, and labrum-reconstructed acetabulum in a hip cadaveric model. The hypothesis was that labral resection would decrease contact area, increase contact pressure, and increase peak force, while subsequent labral reconstruction with ITB autografts or Semi-T allografts would restore these values toward the native intact labral state.

A nomogram to predict major complications after hip and knee arthroplasty.

We aimed to develop a nomogram for risk stratification of major postoperative complications in hip and knee arthroplasty based on preoperative and intraoperative variables, and assessed whether this tool would have better predictive performance compared to the Surgical Apgar Score (SAS). Logistic regression analysis was performed to develop a nomogram. Discrimination and calibration were assessed.

Pediatric physeal ankle fracture.

Ankle fracture is the second most common fracture type in children, and physeal injury is a particular concern. Growing children have open physes that are relatively weak compared with surrounding bone and ligaments, and traumatic injuries can cause physeal damage and fracture. Tenderness to palpation over the physis can aid in the clinical diagnosis of ankle fracture.

The Surgical Apgar Score in hip and knee arthroplasty.

Background: A 10-point Surgical Apgar Score, based on patients' estimated blood loss, lowest heart rate, and lowest mean arterial pressure during surgery, was developed to rate patients' outcomes in general and vascular surgery but has not been tested for patients having orthopaedic surgery.

Questions/purposes: For patients undergoing hip and knee arthroplasties, we asked (1) whether the score provides accurate risk stratification for major postoperative complications, and (2) whether it captures intraoperative variables contributing to postoperative risk based on the three parameters independent of preoperative risk.

Patients And Methods: We retrospectively reviewed the electronic records for all 3511 patients who underwent a hip or knee arthroplasty from March 2003 to August 2006 and extracted data to calculate a Surgical Apgar Score.

The effect of age on the outcomes of arthroscopic repair of type II superior labral anterior and posterior lesions.

Background: The majority of clinical outcome studies of type II superior labral anterior and posterior (SLAP) repair assess patients younger than age 40. Biceps tenotomy or tenodesis is often recommended for patients older than age 40 with superior labrum-biceps complex injury.

Hypothesis: There is no difference in patient clinical outcomes comparing arthroscopic type II SLAP repair in patients younger or older than age 40.

Feasibility of using orthogonal fluoroscopic images to measure in vivo joint kinematics.

Accurately determining in vivo knee kinematics is still a challenge in biomedical engineering. This paper presents an imaging technique using two orthogonal images to measure 6 degree-of-freedom (DOF) knee kinematics during weight-bearing flexion. Using this technique, orthogonal images of the knee were captured using a 3-D fluoroscope at different flexion angles during weight-bearing flexion.
