PURPOSE: To evaluate femoral head-neck bone regrowth and PROs in skeletally immature patients that underwent arthroscopic femoroplasties over a minimum 2-year period. METHODS: Eleven skeletally immature hips (10 patients) with open femoral head physes underwent femoroplasty between October 2008 and November 2013. Inclusion criteria were minimum 2-year follow-up with patient-reported outcomes (PROs) and radiographs preoperatively, at 2 weeks, and at a minimum of 2 years postoperatively...

BACKGROUND: Identifying optimal, post-operative opioid management strategies is a priority of health providers and government agencies. At present, there are no studies we are aware of that have formally investigated opioid prescribing patterns for post-operative non-arthroplasty orthopedic conditions such as femoroacetabular impingement, nor has any study investigated the influence of opioid prescription patterns on health care costs and utilization. We aimed to investigate a subgrouping scheme associated with post-operative opioid prescription strategies and measure the subgroups' direct and indirect health care utilization and costs in individuals undergoing non-arthroplasty orthopedic hip surgery...

BACKGROUND: The minimal clinically important difference (MCID) has been defined in orthopaedics and is the smallest change that a patient considers meaningful. Less is known about improvements that the patient perceives as clinically considerable, or the substantial clinical benefit (SCB). For the young, highly functioning patient cohort with femoroacetabular impingement (FAI), the SCB is an important measure of clinical success. PURPOSE: To derive the SCB for FAI treatment and identify outcome score thresholds and patient variables predictive of the SCB...

BACKGROUND: Femoroacetabular impingement (FAI) most commonly manifests as anterior groin pain. Patients occasionally have posterior pain but otherwise have clinical and radiographic evidence of FAI. PURPOSE: To compare outcomes of hip arthroscopy for FAI in patients with atypical posterior pain versus a matched group with the typical anterior pain presentation. STUDY DESIGN: Cohort study; Level of evidence, 3. METHODS: Patients undergoing primary hip arthroscopy for FAI were identified from a clinical repository between January 2012 and 2014...

CONTEXT: The squat is a fundamental movement for weight lifting and sports performance. Both unilateral and bilateral squats are also used to assess transitional and dynamic lower extremity control. Common lower extremity conditions can have an influence on squat performance. Of interest, are the effects of hip musculoskeletal conditions and associated factors such as hip muscle pain, fatigue, and tightness on squat performance. Currently, there has been no appraisal of the evidence regarding the association of these conditions and associated factors on squat performance...

BACKGROUND: The Proximal Femoral Nail Antirotation (PFNA) system for treatment of intertrochanteric fractures is currently widely applied worldwide. However, even though the PFNA has produced good clinical outcomes, a poor introduction technique with an inappropriate entry point can cause surgical complications. Some researchers suggest improving clinical outcomes by modifying the entry point, but no research has focused on this issue. The purpose of the present study is to compare the clinical and radiological outcomes of two different trochanteric entry points for the treatment of intertrochanteric fractures using the PFNA system...

Dislocation is a serious complication in total hip replacement (THR). An inadequate range of movement (ROM) can lead to impingement of the prosthesis neck on the acetabular cup; furthermore, the initiation of subluxation and dislocation may occur. The objective of this study was to generate a parametric three-dimensional finite element (FE) model capable of predicting the dislocation stability for various positions of the prosthetic head, neck, and cup under various activities. Three femoral head sizes (28, 32, and 36 mm) were simulated...

In Total Hip Replacement (THR), inaccurate measurement of Anterior Pelvic Plane (APP), which is usually used as a reference plane, will lead to malposition of the acetabular prosthesis. As a result, the risk of impingement, dislocation and wear will increase and the safe range of motion will be limited. In order to acquire the accurate pose of APP, a measurement system is designed in this paper, which includes two parts: one is used to estimate the initial pose of APP and the other is used to trail dynamic motion of APP...

Femoro-acetabular impingement (FAI) is associated with significant acetabular cartilage damage and degenerative arthritis. To understand the contact stress and thus biomechanical mechanisms that may contribute to degeneration, the material behaviour of the cartilage layer is required. The objective of this study is to determine the fibril-reinforced poroelastic properties and composition of cartilage from cam deformities and to compare to those of normal cartilage. Patients undergoing surgical treatment of a symptomatic cam FAI deformity were recruited from the clinical practice of one of the authors...

Arpad Konyves
In a retrospective comparative study, pelvic incidence was significantly less in patients with symptomatic femoroacetabular impingement (FAI), with a significant difference in FAI subgroups compared with asymptomatic volunteers. This finding may help to explain the existence of asymptomatic FAI morphology and highlight the importance of thorough assessment of the patient with hip pain.

Historically, athletic hip injuries have garnered little attention; however, these injuries account for approximately 6% of all sports injuries and their prevalence is increasing. At times, the diagnosis and management of hip injuries can be challenging and elusive for the team physician. Hip injuries are seen in high-level athletes who participate in cutting and pivoting sports that require rapid acceleration and deceleration. Described previously as the "sports hip triad," these injuries consist of adductor strains, osteitis pubis, athletic pubalgia, or core muscle injury, often with underlying range-of-motion limitations secondary to femoroacetabular impingement...

BACKGROUND: Despite the large increase in total hip arthroplasties and total knee arthroplasties, the incidence and prevalence of additional contralateral or ipsilateral joint arthroplasty are poorly understood. The purpose of this study was to determine the rate of additional joint arthroplasty after a primary total hip arthroplasty or total knee arthroplasty. METHODS: This historical cohort study identified population-based cohorts of patients who underwent primary total hip arthroplasty (n = 1,933) or total knee arthroplasty (n = 2,139) between 1969 and 2008...

We analyzed the causes leading to total hip arthroplasty (THA), aimed to clarify the incidence of femoroacetabular impingement (FAI) among the causes, and compared the incidence in Korea with those in other countries. From January 2000 to December 2014, 1,206 hips of 818 patients who underwent primary THA at our institute were reviewed retrospectively in terms of radiographs and electronic charts. The radiographs and radiographic parameters were reviewed and measured by 2 of the authors, who are orthopedic surgeons...

Sagittal alignment is known to greatly vary between asymptomatic adult subjects; however, there are no studies on the possible effect of these differences on gait. The aim of this study is to investigate whether asymptomatic adults with different Roussouly sagittal alignment morphotypes walk differently. Ninety-one asymptomatic young adults (46M & 45W), aged 21.6±2.2years underwent 3D gait analysis and full body biplanar X-rays with three-dimensional (3D) reconstructions of their spines and pelvises and generation of sagittal alignment parameters...

Management of the hip capsule has evolved with increased awareness that capsular closure during hip arthroscopy restores the normal anatomy of the ilio-femoral ligament and therefore restores the biomechanical characteristics of the hip joint. Both anatomical and clinical studies have found that capsular closure or plication after hip arthroscopy restores normal motion and allows patients to return to activity more quickly. Capsular closure is technically challenging and increases operative time, but gross instability and microinstability can be avoided with meticulous closure/plication...

REVIEW
Robert Kollmorgen, Richard Mather
Arthroscopic labral repair and refixation have garnered much attention over the past several years. Restoration of suction seal and native labral function has been an evolving focus for achieving excellent results in hip preservation surgery. Authors have reported using several labral management techniques: débridement, labralization, looped suture fixation, base stitch fixation, inversion-eversion, and reconstruction. The optimal technique is yet to be determined. Absolute indications for labral repair are symptomatic intra-articular pain, joint space >2 mm, and failed conservative management...

Jeffrey J Nepple, John C Clohisy
Our understanding of femoroacetabular impingement (FAI) as a cause of hip pain and secondary osteoarthritis has rapidly evolved since Ganz's description in 2003, which refined concepts described a half century earlier. The concepts of cam and pincer-type impingement continue to be better defined and have evolved from relatively simple concepts to more complex and variable disease patterns that are patient-specific. Ganz and colleagues described open treatment of FAI through the development of the surgical hip dislocation approach...

Femoroacetabular impingement (FAI) surgery aims to restore the native anatomical relationships between bones and the soft tissues comprising the hip joint. The goal of this approach is to mimic the natural biomechanical function of the hip joint and translate it into a perfect clinical outcome. In this article, we describe the indications and contraindications for our preferred hip arthroscopic techniques for correcting FAI in both primary and revision cases and discuss the role of postoperative rehabilitation and use of biologics in further improving patient outcomes...
