A retrospective cohort study comparing outcomes following hip fractures in Australian indigenous patients with non-Australian indigenous patients.

Background: Australian Indigenous (AI) populations face significant socioeconomic disadvantage and have poorer health outcomes when compared to their non-AI counterparts. There is a paucity of published literature on outcomes following hip fracture in the AI population.

Methods: We performed a retrospective cohort study comparing outcomes following hip fracture in AI and non- AI patients presenting to a single regional trauma centre.

Closing the health gap in Central Australia: reduction in Indigenous Australian inpatient self-discharge rates following routine collaboration with Aboriginal Health Workers.

Background: Indigenous Australians experience significant socioeconomic disadvantage and healthcare disparity compared to non-Indigenous Australians. A retrospective cohort study to describe the association between rates of self-discharge in Indigenous orthopaedic patients and the introduction of routine Aboriginal Liaison Officers (ALO) within the Orthopaedic multi-disciplinary team (MDT) was performed.

Methods: ALO were introduced within our routine Orthopaedic MDT on the 22 of February 2021.

Safety of intraarticular corticosteroid injection preceding hip and knee arthroplasty: a systematic review and meta-analysis amid resolving COVID-19 arthroplasty restrictions.

Unlabelled: Intraarticular corticosteroid injection (ICSI) is a widely practiced management for hip and knee osteoarthritis. Imposed delays to arthroplasty during coronavirus disease 2019 pandemic have led us to postulate that many patients have opted for recent ICSI. We compared the odds of prosthetic joint infection (PJI) in patients who were or were not administered ICSI within 12 months prior to hip or knee arthroplasty.

Synovial fluid calprotectin performs better than synovial fluid polymerase chain reaction and interleukin-6 in the diagnosis of periprosthetic joint infection : a systematic review and meta-analysis.

Aims: The preoperative diagnosis of periprosthetic joint infection (PJI) remains a challenge due to a lack of biomarkers that are both sensitive and specific. We investigated the performance characteristics of polymerase chain reaction (PCR), interleukin-6 (IL6), and calprotectin of synovial fluid in the diagnosis of PJI.

Methods: We performed systematic search of PubMed, Embase, The Cochrane Library, Web of Science, and Science Direct from the date of inception of each database through to 31 May 2021.

Patients' Perception of Bone and Tissue Excision, and the Size and Weight of Prostheses at Total Knee Arthroplasty.

The aim of this study is to ascertain patients' perception of the amount of bone and tissue excision and size and weight of their implanted prostheses at total knee arthroplasty (TKA). To our knowledge, no prior study in the English orthopaedic literature has analyzed these parameters against patient perception of TKA. In a prospective study of eight consecutive TKA (six primary and two single-stage revision TKA procedures) by a single surgeon, patients estimated the weight of their implanted knee.

Combined Medial Patellofemoral Ligament Reconstruction and Tibial Tubercle Transfer Results at a Follow-Up of 2 years.

There is limited data on the effectiveness of combined medial patellofemoral ligament (MPFL) reconstruction and tibial tubercle transfer (TTT) in patients with patella instability. The aim of our study was to analyze the functional outcome in patients treated with MPFL reconstruction and TTT. Between July 2008 and April 2013, 18 patients (21 knees) underwent combined MPFL reconstruction and TTT; 15 patients (16 knees) with a mean age of 24 years (16-41) had a mean follow-up of 30 months (26-55).

Efficacy of hip resurfacing arthroplasty: 6 year results from an international multisurgeon prospective cohort study.

Metal-on-metal hip resurfacing is undertaken worldwide. This procedure helps preserve femoral bone stock and allows patients to return to high activity sports. Most outcome studies are individual surgeon case series from single centers where the results and outcomes are evaluated by the same surgeon.

Hip Arthroscopy in the Presence of Acetabular Dysplasia.

Purpose: Hip arthroscopy is a well established therapeutic intervention for an increasing number of painful hip conditions. Developmental dysplasia of the hip (DDH) is commonly associated with intra-articular hip pathology. However, some surgeons perceive patients with hip dysplasia as poor candidates for hip arthroscopy.

Apparent Skin Discoloration about the Knee Joint: A Rare Sequela of Metallosis after Total Knee Replacement.

Introduction. Metallosis is a phenomenon most commonly associated with hip replacement. However it can occur in any metallic implant subject to wear.

Medial patellofemoral ligament reconstruction: a technique with a "v"-shaped patellar tunnel.

Patellofemoral dislocation is a common problem affecting the young and active population. The medial patellofemoral ligament (MPFL) is torn when the patella dislocates as it acts as a checkrein to lateral displacement. This leads to patellar instability, and MPFL reconstruction is required if the dislocation recurs after a trial of rehabilitation.

Fat pad entrapment at the hip: a new diagnosis.

Purpose: To establish if a positive impingement sign in femoroacetabular impingement (FAI) may result from entrapment of the fat pad located at the anterior head-neck junction of the upper femur. This fat pad is routinely removed before any cam lesion excision.

Methods: We report a prospective study of 142 consecutive hip arthroscopies for symptomatic FAI where the aim was to remove the arthroscopically identified area of impingement, not necessarily to create a spherical femoral head.

Are crutches required after hip arthroscopy? A case-control study.

Hip arthroscopy provides a less invasive alternative to arthrotomy and has the potential for more rapid rehabilitation. Few guidelines exist for rehabilitation after hip arthroscopic surgery. However, these are not corroborated with evidence of objective outcome measures.

Magnetic resonance arthrography for femoroacetabular impingement surgery: is it reliable?

Background: Magnetic resonance arthrography (MRA) is commonly used to demonstrate injury to the labrum and hyaline cartilage in patients with femoroacetabular impingement (FAI). The purpose of this study was to assess the diagnostic correlation between MRA and findings at arthroscopic and open surgery.

Materials And Methods: MRA reports of 41 hips with symptomatic FAI were reviewed and compared with subsequent intraoperative findings (n = 21 surgical dislocations and n = 20 therapeutic hip arthroscopies).

Revision hip arthroscopic surgery: outcome at three years.

Purpose: This study describes the medium-term results of revision hip arthroscopy.

Methods: Patients with persistent hip pain and a positive impingement sign were considered for revision surgery after the exclusion of other causes of groin pain. Seventy-four consecutive patients were prospectively assessed using the modified Harris hip score for a period of 3 years after surgery.

The accuracy of magnetic resonance arthrography in hip arthroscopic labral revision surgery.

The interpretation of a magnetic resonance arthrogram (MRA) after a labral tear has been surgically treated can be challenging and there is no published evidence on its accuracy. The aim of this study was to evaluate the MRA accuracy in identifying labral pathology after hip arthroscopy. We reviewed 60 patients who had undergone a revision hip arthroscopy.

Does the modified Harris hip score reflect patient satisfaction after hip arthroscopy?

Background: No published studies have explored the relationship between commonly reported clinical outcomes and patient satisfaction after hip arthroscopy.

Purpose: To compare the modified Harris Hip Score (mHHS) with patient satisfaction in a prospective study over a 2-year period.

Study Design: Case series; Level of evidence, 4.

Timing in hip arthroscopy: does surgical timing change clinical results?

Purpose: To our knowledge, there is no report in the orthopaedic literature that correlates the duration of hip pain with the results of hip arthroscopic surgery. The aim of this study was to compare the modified Harris Hip Score (mHHS) with patient satisfaction in a prospective study over a two year period.

Methods: We present a prospective single-surgeon series of 525 consecutive patients undergoing hip arthroscopy for a labral tear, femoroacetabular impingement (FAI), or a chondral lesion.

Long-term clinical outcomes following the use of synthetic hydroxyapatite and bone graft in impaction in revision hip arthroplasty.

Impaction grafting using morsellised allograft bone restores bone stock, but carries the potential for transmission of infection. Synthetic bone graft substitutes can eliminate this risk but may, however, influence outcome. In this study we tested the hypothesis that a 50/50 mix of hydroxyapatite and allograft does not affect long-term function, survival or radiological outcome.

Use of a simple suture to stabilize the chevron osteotomy: a prospective study.

A clinical and radiographic review was undertaken in 27 patients (30 feet) who underwent a chevron osteotomy stabilized with a double loop of polydioxanone suture. The mean patient age at the time of surgery was 40 years (range, 16 to 66 years). At 6 weeks postoperatively, all patients showed clinical and radiographic union at the osteotomy site.
