Clinical outcomes after hip arthroscopy in acetabular dysplastic patients, previously treated with periacetabular osteotomy: a minimum of two-year follow-up data from the Danish Hip Arthroscopy Registry.

Periacetabular osteotomy (PAO) is the treatment of choice in dysplastic acetabulum. Due to continued symptoms, 2-11% of these patients require an additional hip arthroscopy. The purpose of this study was to report clinical outcome after a minimum of 2-year follow-up of additional hip arthroscopy after PAO with data from Danish Hip Arthroscopy Registry.

Proximal Hamstring Avulsions: Surgical Versus Conservative Treatment Using a Shared Decision-Making Strategy.

Background: Surgical treatment of patients with proximal hamstring avulsions provides good results; however, less is known about the outcome in patients who are offered conservative treatment.

Purpose: To investigate the effect of surgical or conservative treatment (decided by a shared decision strategy) of proximal hamstring avulsions.

Study Design: Cohort study; Level of evidence, 2.

Subpectineal obturator nerve block reduces opioid consumption after hip arthroscopy: a triple-blind, randomized, placebo-controlled trial.

Background: Hip arthroscopy causes severe pain during the first few hours in the postoperative care unit. This is probably due to the intraoperative stretching of the hip joint capsule. Pain relief requires high doses of opioids which may prolong recovery and may cause opioid-related adverse events.

First-line treatment for femoroacetabular impingement syndrome and hip-related quality of life: study protocol for a multicentre randomised controlled trial comparing a 6-month supervised strength exercise intervention to usual care (the Better Hip Trial).

Introduction: Femoroacetabular impingement syndrome (FAIS) is a motion-related and position-related clinical condition of the hip associated with pain, reduced physical function and hip-related quality of life (QoL). Interestingly, higher maximal muscle strength is associated with less pain, better physical function and improved QoL in people with FAIS. Furthermore, preliminary evidence suggests that a proportion of patients with FAIS respond positively to strength exercise as first-line treatment.

Open surgical repair of hip abductor tendon tears.

Introduction: Tendinopathy and tendon tears of the gluteus medius and/or minimus (GMM) insertion at the greater trochanter are increasingly recognised internationally as a cause of recalcitrant lateral hip pain (LHP). The purpose of this study was to report the first Danish results of open surgical repair of GMM tears in female patients.

Methods: In this retrospective observational study, we included 67 women (68 hips) with a mean (95% confidence interval (CI)) age of 59 (56-61) years who underwent open GMM repair between September 2018 and June 2022.

Efficacy of iliopsoas plane block for patients undergoing hip arthroscopy: a prospective, triple-blind, randomized, placebo-controlled trial.

Background: Intraoperative stretching of the hip joint capsule often generates severe pain during the first 3 hours after hip arthroscopy. The short-lived severe pain mandates high opioid consumption, which may result in adverse events and delay recovery. The femoral nerve nociceptors are located anteriorly in the hip joint capsule.

Limited clinical utility of a machine learning revision prediction model based on a national hip arthroscopy registry.

Purpose: Accurate prediction of outcome following hip arthroscopy is challenging and machine learning has the potential to improve our predictive capability. The purpose of this study was to determine if machine learning analysis of the Danish Hip Arthroscopy Registry (DHAR) can develop a clinically meaningful calculator for predicting the probability of a patient undergoing subsequent revision surgery following primary hip arthroscopy.

Methods: Machine learning analysis was performed on the DHAR.

Low prevalence of trochanteric bursitis in patients with refractory lateral hip pain.

Introduction: Bursitis at the greater trochanter has historically been identified as a major pain generator in patients with lateral hip pain (LHP). We believe that hip abductor tendon pathology (HATP) plays an important and overlooked role in LHP. The purpose of this study was to evaluate the presence of isolated trochanteric bursitis on MRI in patients with refractory LHP.

Five-Year Follow-up After Hip Arthroscopic Surgery in the Horsens-Aarhus Femoroacetabular Impingement (HAFAI) Cohort.

Background: Patients with femoroacetabular impingement syndrome (FAIS) are offered hip arthroscopic surgery to decrease hip pain, improve their function, and decrease development of hip osteoarthritis (OA). Nonetheless, long-term follow-up data are few.

Purpose: To investigate patient-reported outcomes, clinical tests, reoperations, and radiographic status 5 years after primary hip arthroscopy in patients with FAIS.

Gluteal-related lateral hip pain.

Introduction: Lateral hip pain (LHP) due to tendon pathologies of insertion of the M. gluteus medius and minimus at the greater trochanter are often misdiagnosed and may lead to unrecognised disability. The purpose of this study was to evaluate pain and patient-reported outcomes in patients presenting with LHP in the context of a publicly financed healthcare system.

Os acetabuli-a new arthroscopic treatment option for the acetabular rim fracture.

Os acetabuli (Os) or acetabular rimfractures are often seen in femoroacetabular impingement patients and can result in groin pain. When seen in symptomatic patients, the question is whether to remove them or to fixate the loose fragment to the acetabular rim. This depends on acetabular coverage and the extent of the Os.

[Abductor-related lateral hip pain in patients older than 30 years].

Lateral hip pain is a complex entity, and recent focus has been brought to pathological changes in relation to the hip abductors as a cause of lateral hip pain. A short overview of anatomy, physiology, diagnostics and treatments of hip abductor pathologies is given in this review.

External Snapping Hip Syndrome Endoscopic Treatment: "Fan-like" Technique as a Stepwise, Tailor-made Solution.

Classically, external snapping hip syndrome (ESHS) is considered to be caused by friction of a tight iliotibial band (ITB) over the greater trochanter (GT), which leads to pain, inflammation, and palpable or audible snapping. Surgical treatment remains a gold standard in patients resistant to conservative measures. Many surgical procedures addressing ESHS exist in the literature, but the vast majority of them involve only plasties of the ITB.

A roadmap to develop clinical guidelines for open surgery of acute and chronic tears of hip abductor tendons.

Purpose: Abductor tendon tears are increasingly recognised as a common cause of lateral hip pain. Surgical treatment of these tears has been recommended, but the indications and types of open surgery have not been precisely elucidated yet. This manuscript aimed to critically review the literature concerning all open treatment options for this condition while identifying knowledge gaps and introducing a treatment algorithm.

Capsular closure in patients with femoroacetabular impingement syndrome (FAIS): results of a matched-cohort study from the Danish hip arthroscopy registry.

Capsular closure in femoroacetabular impingement syndrome (FAIS) patients during hip arthroscopy procedures is debated. The Danish Hip Arthroscopy Registry (DHAR) contains data to perform matched-cohort analyses. The purpose of this study is to evaluate 1-year subjective outcome data from DHAR after hip arthroscopy for FAIS with capsular closure and compare these outcome data with a matched-cohort study group.

The Danish Hip Arthroscopy Registry: Registration Completeness and Patient Characteristics Between Responders and Non-Responders.

Purpose: To report completeness of registered surgeries in the Danish hip arthroscopy registry (DHAR) and proportion of patients completing patient-reported outcome measures (PROMs) prior to surgery and at 1-year follow-up.

Patients And Methods: Completeness was determined as the number of surgeries registered in DHAR in comparison with the number of surgeries registered in the Danish National Patient Registry database (DNPR). The number of patients self-reporting pre-surgical PROMs was compared to the total number of surgeries registered in DHAR.

Clinical outcomes after revision hip arthroscopy in patients with femoroacetabular impingement syndrome (FAIS) are inferior compared to primary procedures. Results from the Danish Hip Arthroscopy Registry (DHAR).

Purpose: As many as 10% of primary hip arthroscopies end up with a revision arthroscopy procedure when treating patients suffering from femoroacetabular impingement syndrome (FAIS). In general, revision procedures are indicated because of residual impingement, but only a few studies present outcome data from revision hip arthroscopy after failed FAIS surgical treatment. The purpose of this study was to evaluate clinical outcomes after revision hip arthroscopy in a FAIS cohort and compare outcomes with a primary FAIS hip arthroscopy cohort and describe potential causes of failure after the primary hip arthroscopy.

An Updated Description of More Than 5,000 Procedures from the Danish Hip Arthroscopy Registry.

Background: The Danish Hip Arthroscopy Registry (DHAR) started as a web-based prospective registry in 2012. The aim of this study was to evaluate and report epidemiologic and perioperative data from 5,333 procedures and to describe the development of the DHAR.

Methods: The DHAR collects data from patients prospectively at the time of inclusion (preoperative evaluation) and at 1, 2, 5, and 10 years after arthroscopic hip surgery.

[Younger patients with hip joint pain].

This review summarises the present knowledge of diagnosing and treating hip joint pain. The results of joint preserving surgery are good in symptomatic patients with hip dysplasia, acetabular retroversion or impingement (cam or pincer) without signs of osteoarthritis. Confirmation of intraarticular pathology as the cause of symptoms is established clinically, and the pathology can in many cases be visualised by a standing, standardised radiograph of the pelvis, which is the basis for admission to the relevant orthopaedic department.

High relative reliability and responsiveness of the forgotten joint score-12 in patients with femoroacetabular impingement undergoing hip arthroscopic treatment. A prospective survey-based study.

The forgotten joint score-12 (FJS-12) may be an advantageous questionnaire in young patients with high hip function and a low level of pain. We investigated the reliability and the responsiveness of the FJS-12 in patients with femoroacetabular impingement undergoing hip arthroscopic treatment. Fifty patients were included in the reliability study and 34 patients were included in the responsiveness study.

Demographic and Radiographic Factors Associated With Intra-articular Hip Cartilage Injury: A Cross-sectional Study of 1511 Hip Arthroscopy Procedures.

Background: Moderate to severe (grade 3-4) hip joint cartilage injury seems to impair function in patients with femoroacetabular impingement syndrome.

Purpose: To investigate whether demographic and radiographic factors were associated with moderate to severe hip joint cartilage injury.

Study Design: Cross-sectional study; Level of evidence, 3.

Despite patient-reported outcomes improve, patients with femoroacetabular impingement syndrome do not increase their objectively measured sport and physical activity level 1 year after hip arthroscopic surgery. Results from the HAFAI cohort.

Purpose: Patients with femoroacetabular impingement syndrome (FAIS) are young and middle-aged persons living physically active lives including sports activities. However, measurements of the physical activity level before and after hip arthroscopic surgery in patients with FAIS using both self-reported and objective accelerometer-based measures are lacking. Furthermore, comparing patients with a reference group of persons reporting no hip problems and conducting subgroup analyses investigating changes in physical activity level and self-reported outcomes according to pre-surgery activity level may further highlight the activity pattern for patients.

[Femoroacetabular impingement syndrome].

Femoroacetabular impingement syndrome (FAIS) is defined as a motion-related disorder of the hip joint, consisting of a triad of symptoms, clinical findings, and imaging findings. Hip morphology related to FAIS is developed during skeletal growth and seems to be related to sports participation. Treatment for FAIS may include physiotherapy and/or surgery, but recent evidence suggests, that surgery is more effective in improving symptoms.

Good midterm results of hip arthroscopy for femoroacetabular impingement.

Introduction: Short-term outcome after hip arthroscopy for femoroacetabular impingement (FAI) has been reported to improve hip function and decrease pain. Only few midterm and long-term studies have been published. The objective of this study was to report midterm results in a consecutive cohort and to study the relation between cartilage lesions and the conversion rate to total hip arthroplasty (THA).

Danish Hip Arthroscopy Registry: predictors of outcome in patients with femoroacetabular impingement (FAI).

Purpose: Predictors of outcome after femoroacetabular impingement (FAI) surgery are not well-documented. This study presents data from the Danish Hip Arthroscopy Registry (DHAR) for such analyses. The purpose of this study was to identify predictors of poor outcome after FAI surgery in a Danish FAI population.
