BACKGROUND: Hip arthroscopy has emerged as a successful option for the treatment of femoroacetabular impingement and related hip disorders, but the procedure is technically challenging. PURPOSE: To define the learning curve through which surgeons become proficient at hip arthroscopy. STUDY DESIGN: Cohort study; level of evidence, 3. METHODS: The authors identified hip arthroscopy procedures performed by surgeons through a New York State database (Statewide Planning and Research Cooperative System) and followed those cases for additional hip surgery (total hip arthroplasty, hip resurfacing, or ipsilateral hip arthroscopy) within 5 years of the original procedure...

PURPOSE OF REVIEW: To discuss the clinical significance of the most common hip and groin injuries in baseball players, as well as an algorithmic approach to diagnosis and treatment of these injuries. RECENT FINDINGS: (a) Limitations in throwing velocity, pitch control, and bat swing speed may be secondary to decreased mobility and strength within the proximal kinetic chain, which must harness power from the lower extremities and core. (b) Approximately 5.5% of all baseball injuries per year involve the hip/groin and may lead to a significant amount of time spent on the disabled list...

Acetabular and spino-pelvic (SP) morphological parameters are important determinants of hip joint dynamics. This prospective study aimed to determine whether acetabular and SP morphological differences exist between hips with and without cam morphology and between symptomatic and asymptomatic hips with cam morphology. A cohort of 67 patients/hips was studied. Hips were either asymptomatic with no cam (Controls, n = 18), symptomatic with cam (n = 26) or asymptomatic with cam (n = 23). CT-based quantitative assessments of femoral, acetabular, pelvic and spino-pelvic parameters were performed...

INTRODUCTION: The Taperloc® Complete femoral stem (Zimmer Biomet, Warsaw, Indiana) builds on the widespread clinical success of the original Taperloc design used since 1982. Enhancements to the Complete design include a lowered caput-collum-diaphyseal (CCD) angle from 138° to 133° for improved offset, optimized neck taper with polished neck flats to increase range of motion, reduced distal geometry to improve proximal canal fill, and gradual off-loading that is the goal of tapered geometry...

BACKGROUND: Increased mechanical load secondary to a large body mass index (BMI) may influence bone remodeling. The purpose of this study was to investigate whether BMI is associated with the morphology of the proximal part of the femur and the acetabulum in a cohort of adolescents without a history of hip disorders. METHODS: We evaluated pelvic computed tomographic (CT) images in 128 adolescents with abdominal pain without a history of hip pathology. There were 44 male patients (34%) and the mean patient age (and standard deviation) was 15 ± 1...

BACKGROUND: Tears of the Ligamentum Teres are a common cause of groin pain. Tears of the ligament frequently co-exist alongside other bony or labral intra-articular hip lesions, which are also treated at the time of arthroscopy. For this reason, it is often difficult to assess the effect that debridement alone has on improving patient pain and function. This study aims to assess the short-term outcomes of arthroscopic debridement of isolated Ligamentum Teres tears using a validated patient-reported outcome score - the International Hip Outcome Tool (iHOT-33)...

We report a case of concurrent bilateral hip arthroscopy for symptomatic bilateral femoroacetabular impingement (FAI) performed under the single anesthesia on an elite rugby player. A 27-year-old rugby player who played for a top league had bilateral hip joint pain. Physical examination revealed bilateral tenderness in the anterior area of the hips, with positive impingement signs. Based on the findings of hip radiography and magnetic resonance imaging, the patient's symptoms were diagnosed as bilateral FAI with hip labral tears...

The purpose of this study is to report on the operative findings and the outcomes of revision hip arthroscopy. All hip arthroscopy cases are prospectively assessed with a modified Harris Hip Score (mHHS) preoperatively and postoperatively. This study consists of 190 consecutive hips (186 patients) who underwent revision arthroscopy with minimum 2-year follow-up. There were 69 males and 117 females with a mean age of 32.7 (14-64). The mean time from index to revision procedure was 24.5 months (3-146). Common diagnoses included labral tears (102) and unaddressed or residual femoroacetabular impingement (FAI) (49 cam, 11 pincer, and 20 combined)...

The early post-operative course after hip arthroscopy for femoroacetabular impingement syndrome has not been thoroughly characterized or correlated to factors that may influence recovery. The aim of this study was to report on early pain, function and attitudes towards rehabilitation and to determine predictors of early recovery after hip arthroscopy. Sixty-two patients reported pre-operative pain, iHOT-12 (hip functional score), psychological status and other baseline characteristics. Pain, iHOT-12, hip flexion and several other outcomes were measured through 6 weeks post-operative...

Ischiofemoral impingement (IFI) is a rare cause of hip pain defined by a narrowing of the space between the lateral aspect of the os ischium and the lesser trochanter of the femur. Several underlying anatomic, functional and iatrogenic pathologies have been identified for symptomatic IFI in native hip joints and after total hip arthroplasty. Clinical symptoms vary but most commonly consist of pain of the lower buttock and groin including the inner thigh, and a snapping or clunking phenomenon is often reported...

Redirective, periacetabular osteotomies (PAO) represent a group of surgical procedures for treatment of developmental dysplasia of the hip (DDH) in skeletally mature and immature patients. The ultimate goal of all procedures is to reduce symptoms, improve function and delay or prevent progression of osteoarthritis. During the last two decades, the understanding of the underlying pathomechanisms has continuously evolved. This is mainly attributable to the development of the femoroacetabular impingement concept that has increased the awareness of the underlying three-dimensional complexity associated with DDH...

INTRODUCTION: Although combined evaluation of hip joint kinematics and bone morphology is necessary for accurate assessment of femoroacetabular impingement (FAI), there are no report which evaluated hip kinematics of pincer-type FAI. PRESENTATION OF CASE: The pre- and postoperative hip kinematics of a 46-year-old man, with a pincer-type FAI during squat were evaluated using image-matching techniques and the rim-neck distance was measured. Preoperative simulation of squatting was also performed using patient's bone models and healthy subject's kinematics data to detect the overlapping lesion between the acetabulum and the femur...
