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.

Resorption characteristics of an open architecture biocomposite interference screw after ACL reconstruction.

Purpose: Absorbable interference screws for anterior cruciate ligament reconstruction (ACLR) can lead to tunnel widening and cyst formation. The Biosure Regenesorb interference screw (Smith & Nephew). has been developed with an optimised calcium phosphate/polymer composition to promote bone formation during resorption.

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.

Exercise compared to a control condition or other conservative treatment options in patients with Greater Trochanteric Pain Syndrome: a systematic review and meta-analysis of randomized controlled trials.

Objectives: To estimate the effectiveness of exercise at end of treatment and long-term follow-up compared to a control condition or other conservative treatments in patients with Greater Trochanteric Pain Syndrome (GTPS).

Methods: Databases were searched September 2021 and updated September 2023. Randomized controlled trials (RCT) comparing exercise interventions for patients with GTPS, to a control condition; corticosteroid injection; shock wave therapy; or other types of exercise programs were included.

Opportunity to Perform - Should Simulation-Based Surgical Training be Provided on Demand or on Supply?

Introduction: The aim of the study was to assess the surgical case volume of residents before and after simulation-based training in hip fracture surgery provided on demand versus knee and shoulder arthroscopy provided on supply.

Materials And Methods: A retrospective analysis of surgical case volume in hip fracture surgery and arthroscopic shoulder and knee procedures 90 days before and after simulation-based training of either procedure. Sixty-nine orthopedic residents voluntarily participating in either simulation-based training.

Combined anterior cruciate ligament revision with reconstruction of the antero-lateral ligament does not improve outcome at 2-year follow-up compared to isolated acl revision; a randomized controlled trial.

Purpose: It is essential to obtain rotational stability of the knee after anterior cruciate ligament reconstruction (ACL-R) and it is suggested that a supplementary reconstruction of the antero-lateral ligament (ALL-R) may supports this. Theoretically, ALL-R may be particularly advantageous to support revision of failed ACL-Rs. It was hypothesized that ACL revision combined with ALL-R will result in superior outcome compared to isolated ACL revision.

Muscle Strength, Oxygen Saturation and Physical Activity in Patients with Chronic Exertional Compartment Syndrome Compared to Asymptomatic Controls.

Background: One of the most common causes of exercise-induced pain in the lower leg is chronic exertional compartment syndrome (CECS). Research is limited on muscle strength, oxygen saturation and physical activity in patients with CECS.

Purpose: To compare muscle strength, oxygen saturation, and daily physical activity between patients with CECS and matched asymptomatic controls.

Hip joint motion does not change one year after arthroscopic osteochondroplasty in patients with femoroacetabular impingement evaluated with dynamic radiostereometry.

Purpose: Dynamic radiostereometric analysis (dRSA) enables precise non-invasive three-dimensional motion-tracking of bones for assessment of joint kinematics. Hereby, the biomechanical effects of arthroscopic osteochondroplasty of the hip (ACH) can be evaluated in patients with femoroacetabular impingement (FAI). The aim was to investigate the pre- and postoperative range of motion (ROM) and the CT bone volume removed (BV) after ACH.

[Joint-preserving surgery in hip and knee and development of secondary osteoarthritis].

The purpose of this review was to elucidate if surgery can prevent secondary osteoarthritis (OA) in hip dysplasia, femoroacetabular impingement syndrome, varus malalignment of the knee, patella instability, anterior cruciate ligament injury and intra-articular fracture of the knee or hip. In conclusion, there is evidence that surgery for intra articular fracture of the knee or hip reduces the risk of secondary OA. There is a lack of prospective comparative studies for the remaining investigated conditions and as such no convincing evidence that surgery reduces the risk of secondary OA.

High-volume image-guided injection in the chronic recalcitrant non-insertional patellar tendinopathy: a retrospective case series.

Purpose: To evaluate if High-volume Image-guided Injection (HVIGI)-treatment for chronic Patellar tendinopathy (PT) improve function and reduce pain at 16-months follow-up.

Methods: Patients with resistant PT who failed to improve after a three-month eccentric loading program were included in the study. Maximal tendon thickness was assessed with ultrasound.

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.

Bone ingrowth into open architecture PEEK interference screw after ACL reconstruction.

Purpose: Open or fenestrated interference screw design that allow bone ingrowth is a concept for improved bone healing to softtissue graft and bone filling in bone tunnels after anterior cruciate ligament reconstruction (ACLR) The aim of the current study was to assess CT scanning evaluated bone ingrowth into an open architecture interference screws in the tibial tunnel of patients undergoing ACL with soft tissue grafts. It was hypothesized that open architecture interference screws would stimulate bone ingrowth into the screw cavities.

Methods: Twelve patients requiring ACLR were included.

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.

The effect of high-volume image-guided injection in the chronic non-insertional Achilles tendinopathy: a retrospective case series.

Purpose: To evaluate if High-volume Image-guided Injection (HVIGI)-treatment for chronic mid-portion Achilles tendinopathy (AT) improve function and reduce pain at 12-months follow-up.

Methods: Patients with resistant mid-portion AT who failed to improve after a three-month eccentric loading program were included in the study. Maximal tendon thickness was assessed with ultrasound.

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.

A simple rehabilitation regime improves functional outcome in patients with patellafemoral pain after 12 month.

Purpose: The purpose of the present study was to investigate the effects of a 3-month multimodal intervention including patient education, a simple hip exercise program, footwear adjustment, and foot orthoses to reduce symptoms in patients with patellafemoral pain (PFP).

Methods: Patients were diagnosed based on a physical examination, patient symptoms and ruled out intra-articular knee pathologies by MRI. Patients were educated on PFP and participated in a 3-month exercise program; shoes with solid heel-caps were recommended, and custom made orthoses with arch support were recommended to patients with foot pronation.

[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.

Quadriceps tendon grafts does not cause patients to have inferior subjective outcome after anterior cruciate ligament (ACL) reconstruction than do hamstring grafts: a 2-year prospective randomised controlled trial.

Objective: We performed a randomised controlled trial (RCT) in patients undergoing ACL reconstruction (ACLR) using either quadriceps tendon graft (QT) or semitendinosus/gracilis hamstring (STG) graft. We compared subjective outcome (primary outcome) and knee stability, donor site morbidity and function (secondary outcomes).

Methods: From 2013 to 2015, we included 99 adults with isolated ACL injuries in the RCT.

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.

No Difference in Outcome Between Femoral Soft-Tissue and Screw Graft Fixation for Reconstruction of the Medial Patellofemoral Ligament: A Randomized Controlled Trial.

Purpose: The aim of the present randomized controlled trial was to compare 2 different medial patellofemoral ligament reconstruction (MPFL-R) techniques that utilize different femoral fixation principles, which could affect subjective clinical outcomes and surgical morbidity.

Methods: Sixty patients were randomly assigned to 2 MPFL-R techniques: bone or soft-tissue fixation of the graft at the femoral condyle. Patients had operations performed between 2010 and 2015 at a single center.

[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.

The interface between periacetabular osteotomy, hip arthroscopy and total hip arthroplasty in the young adult hip.

Hip pain is highly prevalent in both the younger and the elderly population. In older patients, pain arising from osteoarthritis (OA) is most frequent, whereas in younger patients, non-degenerative diseases are more often the cause of pain. The pain may be caused by hip dysplasia and femoroacetabular impingement (FAI).

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.

Multicentre study on capsular closure versus non-capsular closure during hip arthroscopy in Danish patients with femoroacetabular impingement (FAI): protocol for a randomised controlled trial.

Introduction: Hip arthroscopy has become a standard procedure in the treatment of hip joint pain not related to osteoarthritis or dysplasia in the young and active patient. There has been increasing focus on the contribution of the hip capsule to function and on stability following hip arthroscopy. It has been suggested that capsular closure after hip arthroscopy may prevent microinstability and macroinstability of the hip joint and reduce revision rate.

[Treatment of meniscal pathology].

The menisci play a major role in knee function regarding joint movement, stability, load distribution and load transmission. Injuries to the menisci cause pain, and meniscal tears are a common reason for patient referral. In Denmark, partial meniscectomy increased significantly until 2010, and several studies have questioned the long-term effect of meniscectomy as an overall procedure.
