Aims

The use of patient-reported outcome measures (PROMs) to assess the outcome after total knee (TKA) and total hip arthroplasty (THA) is increasing, with associated regulatory mandates. However, the robustness and clinical relevance of long-term data are often questionable. It is important to determine whether using long-term PROMs data justify the resources, costs, and difficulties associated with their collection. The aim of this study was to assess studies involving TKA and THA to determine which PROMs are most commonly reported, how complete PROMs data are at ≥ five years postoperatively, and the extent to which the scores change between early and long-term follow-up.

Methods

We conducted a systematic review of the literature. Randomized controlled trials (RCTs) with sufficient reporting of PROMs were included. The mean difference in scores from the preoperative condition to early follow-up times (between one and two years), and from early to final follow-up, were calculated. The mean rates of change in the scores were calculated from representative studies. Meta-analyses were also performed on the most frequently reported PROMs.

Aims

To develop a multidisciplinary health research agenda (HRA) utilizing expertise from various disciplines to identify and prioritize evidence uncertainties in orthopaedics, thereby reducing research waste.

Methods

We employed a novel, structured framework to develop a HRA. We started by systematically collecting all evidence uncertainties from stakeholders with an interest in orthopaedic care, categorizing them into 13 sub-themes defined by the Dutch Orthopaedic Association (NOV). Subsequently, a modified two-phased Delphi study (two rounds per phase), adhering to the Conducting and REporting DElphi Studies (CREDES) guideline, was conducted. In Phase 1, board members assessed the collected evidence uncertainties on a three-point Likert scale to confirm knowledge gaps. In Phase 2, diverse stakeholders, including orthopaedic surgeons, rated the confirmed knowledge gaps on a seven-point Likert scale. Panel members rated one self-selected sub-theme and two randomly assigned sub-themes. The results from Phase 2 were ranked based on the overall average score for each uncertainty. Finally, a focus group discussion with patient associations’ representatives identified their top-ranked uncertainty from a predefined consensus process, leading to the final HRA. An advisory board, the Federation of Medical Specialists, and the NOV research coordinator oversaw the process.

Aims

Revision hip arthroplasty for femoral stem loosening remains challenging due to significant bone loss and deformities requiring specialized revision stems. The aim of this study was to evaluate the clinical and radiological outcomes, and survival, of a consecutive series of femoral revisions performed using a primary cementless stem with tapered geometry and rectangular cross-section at medium-term follow-up.

Methods

We retrospectively evaluated 113 patients (115 hips) with intraoperative Paprosky type I (n = 86) or II (n = 29) defects, who underwent femoral revision with Alloclassic Zweymüller SL stem for one-stage aseptic revision or two-stage septic revision from January 2011 to December 2020. The mean follow-up was 77.9 months (SD 33.8). Nine patients were lost to follow-up (deceased or not available), leaving 104 patients (106 hips) for the clinical and radiological analysis. Clinical assessment was performed with Harris Hip Score (HHS) and visual analogue scale (VAS) before surgery and at final follow-up.

Aims

HIV and musculoskeletal injuries both disproportionately affect individuals living in low- and middle-income countries (LMICs), leading to a significant number of fractures in HIV-positive patients. Despite this, little is known about the long-term outcomes for these patients. This prospective cohort study investigated whether HIV infection is associated with fracture-related infections (FRIs).

Methods

All adult patients between September 2017 and December 2018 who received intramedullary nail fixation of lower limb fractures in two tertiary referral hospitals in Cape Town, South Africa, were deemed eligible. In total, 358 participants were recruited for this study, 33 of whom were lost to follow-up. Of the 325 participants, 37 (11.4%) developed a total of 39 FRIs over the study period; 25 were early FRIs (64.1%) and 14 were late FRIs (35.9%). Participants were followed up for a minimum of 24 months. Throughout follow-up, participants were monitored for FRIs. These were categorized as early FRIs (< 90 days) and late FRIs (> 90 days).

Aims

While cementless fixation offers potential advantages over cemented fixation, such as a shorter operating time, concerns linger over its higher cost and increased risk of periprosthetic fractures. If the risk of fracture can be forecasted, it would aid the shared decision-making process related to cementless stems. Our study aimed to develop and validate predictive models of periprosthetic femoral fracture (PPFF) necessitating revision and reoperation after elective total hip arthroplasty (THA).

Methods

We included 154,519 primary elective THAs from the Swedish Arthroplasty Register (SAR), encompassing 21 patient-, surgical-, and implant-specific features, for model derivation and validation in predicting 30-day, 60-day, 90-day, and one-year revision and reoperation due to PPFF. Model performance was tested using the area under the curve (AUC), and feature importance was identified in the best-performing algorithm.

Aims. Trauma & Orthopaedic (T&O) surgery has come under scrutiny for lagging behind other medical specialties in promoting gender and cultural equity and diversity within their workforce. The proportions of female, ethnic minority, and sexual and gender minority individuals within orthopaedic membership bodies are disproportionate to the populations they serve. The aim of this study is to report the findings of a national workforce survey of demographics and working patterns within T&O in Scotland. Methods. A questionnaire devised by a working group was delivered by the Client Analyst and Relationship Development (CARD) group. Utilizing a secure third party ensured anonymity for all respondents. Data were recorded and analyzed by the CARD group. Results. A total of 353 responses were recorded, representing 71% of the known workforce. Overall, 261 respondents (74%) identified as male, 85 (24%) female, and seven (2%) preferred not to say. For specialist trainee (ST)3 to ST6, 148 (42%) were female, and for ST7 to ST8, 131 (37%) were female. In total, 226 of all respondents (64%) were white-British, 35 (10%) were white-European, and 92 (26%) were of an ethnic minority background. A total of 321 of respondents (91%) identified as heterosexual, 14 (4%) preferred not to say, and 18 (5%) identified as LGBTQ+ or preferred to self-describe. Conclusion. This is the largest national workforce survey in contemporary surgical literature. The findings demonstrate a greater proportion of female surgeons overall compared to other studies in T&O. This proportion of females was highest among more junior trainees. The Scottish T&O workforce is more ethnically diverse than the demographics of the population it serves. This study suggests that T&O in Scotland is an evolving speciality in terms of equality and diversity, and is making positive progress. Cite this article: Bone Jt Open 2025;6(1):103–108

Aims

Magnesium ions (Mg2+) play an important role in promoting cartilage repair in cartilage lesions. However, no research has focused on the role of Mg2+ combined with microfracture (MFX) in hyaline-like cartilage repair mediated by cartilage injury. This study aimed to investigate the beneficial effects of the combination of MFX and Mg2+ in cartilage repair.

Methods

A total of 60 rabbits were classified into five groups (n = 12 each): sham, MFX, and three different doses of Mg2+ treatment groups (0.05, 0.5, and 5 mol/L). Bone cartilage defects were created in the trochlear groove cartilage of rabbits. MFX surgery was performed after osteochondral defects. Mg2+ was injected into knee joints immediately and two and four weeks after surgery. At six and 12 weeks after surgery, the rabbits were killed. Cartilage damage was detected by gross observation, micro-CT, and histological analysis. The expression levels of related genes were detected by real-time quantitative reverse transcription polymerase chain reaction (RT-qPCR).

Aims

We evaluated the national and regional trends from 2013 to 2022, in the prevalence of Perthes’ disease among adolescent males in South Korea.

Methods

This retrospective, nationwide, population-based study included a total of 3,166,669 Korean adolescent males examined at regional Military Manpower Administration (MMA) offices over ten years. Data from the MMA were retrospectively collected to measure the national and regional prevalence per 100,000 and 95% CI of Perthes’ disease according to the year (1 January 2013 to 31 December 2022) and history of pelvic and/or femoral osteotomy in South Korea. Spearman’s correlation analysis was performed to assess the relationship between the Perthes’ disease prevalence and several related factors.

Aims

Arthroplasty has been shown to generate the most waste among all orthopaedic subspecialties, and it is estimated that hip and knee arthroplasty generate in excess of three million kg of waste annually in the UK. Infectious waste generates up to ten times more CO2 compared with recycled waste, and previous studies have shown that over 90% of waste in the infectious stream is misallocated. We assessed the effect of real-time waste segregation by an unscrubbed team member on waste generation in knee and hip arthroplasty cases, and compared this with a simple educational intervention during the ‘team brief’ at the start of the operating list across two sites.

Methods

Waste was categorized into five categories: infectious, general, recycling, sharps, and linens. Each category was weighed at the end of each case using a digital weighing scale. At Site A (a tertiary orthopaedic hospital), pre-intervention data were collected for 16 total knee arthroplasy (TKA) and 15 total hip arthroplasty (THA) cases. Subsequently, for ten TKA and ten THA cases, an unscrubbed team member actively segregated waste in real-time into the correct streams. At Site B (a district general hospital), both pre- and post-intervention groups included ten TKA and ten THA cases. The intervention included reminding staff during the ‘team brief’ to segregate waste correctly.
