RESUMEN
Aims: Our primary aim was to establish the proportion of female orthopaedic consultants who perform arthroplasty via cases submitted to the National Joint Registry (NJR), which covers England, Wales, Northern Ireland, the Isle of Man, and Guernsey. Secondary aims included comparing time since specialist registration, private practice participation, and number of hospitals worked in between male and female surgeons. Methods: Publicly available data from the NJR was extracted on the types of arthroplasty performed by each surgeon, and the number of procedures of each type undertaken. Each surgeon was cross-referenced with the General Medical Council (GMC) website, using GMC number to extract surgeon demographic data. These included sex, region of practice, and dates of full and specialist registration. Results: Of 2,895 surgeons contributing to the NJR in 2023, 102 (4%) were female. The highest proportions of female surgeons were among those who performed elbow (n = 25; 5%), shoulder (n = 24; 4%), and ankle (n = 8; 4%) arthroplasty. Hip (n = 66; 3%) and knee arthroplasty (n = 39; 2%) had the lowest female representation. Female surgeons had been practising for a median of 10.4 years since specialist registration compared to 13.7 years for males (p < 0.001). Northern Ireland was the region with the highest proportion of female arthroplasty surgeons (8%). A greater proportion of male surgeons worked in private practice (63% vs 24%; p < 0.001) and in multiple hospitals (74% vs 40%; p < 0.001). Conclusion: Only 4% of surgeons currently contributing cases to the NJR are female, with the highest proportion performing elbow arthroplasty (5%). Female orthopaedic surgeons in the NJR are earlier in their careers than male surgeons, and are less involved in private practice. There is a wide geographical variation in the proportion of female arthroplasty surgeons.
RESUMEN
INTRODUCTION: Noise-Induced Hearing Loss (NIHL) is a condition caused by repeated exposure to loud noise, with operating theatre personnel potentially at risk. The aims of this study were to establish the typical noise levels in orthopaedic theatres and to compare these to The Control of Noise at Work Regulations 2005. MATERIALS AND METHODS: We measured the average noise levels in 40 trauma and orthopaedic surgeries in a single centre. We used the Decibel X app to take measurements, then performed corrections to ascertain noise levels at the surgeon's ear (Leq). The daily noise exposure level for theatre staff for each procedure (LEP, d) and the LEP, d over an average 8-hour working day when performing different groups of procedures were calculated. Data were analysed using descriptive statistics, ANOVA, t-test and the Pearson coefficient of correlation. RESULTS: The LEP, d lower action value (80 dBA) as set by the Health and Safety Executive (HSE) was met by performing a single revision total knee replacement or a right open ankle debridement. Assuming three procedures are conducted per list, lists consisting of joint replacements (82 dBA) or medium elective procedures (81 dBA) exceed this lower limit. Additionally, lists comprising large and medium bone fractures would be within 1 dB of the limit (79 dBA and 79 dBA, respectively). Soft tissue (74 dBA), arthroscopic (73 dBA), and small bone fracture (71 dBA) procedures had the lowest LEP, d. The greatest contributors to noise levels were surgical instruments. The number of people in the room made a significant difference to noise levels (p = 0.032). CONCLUSIONS: We have established the baseline noise levels in various orthopaedic procedures. Measures should be taken to meet UK regulations. Further research should determine suitable measures for protection from hearing damage for theatre staff and evaluate the risks high noise levels pose to patients.
RESUMEN
RATIONALE: The National Health Service (NHS) Long Term Plan was published in January 2019. One of its objectives was restructuring outpatient services, as part of an Outpatient Transformation initiative. Monitoring of trusts' adherence to the objectives of the Long Term Plan is therefore required to benchmark progress against national objectives. AIMS AND OBJECTIVES: We aimed to explore whether outpatient transformation initiatives and phlebotomy services that are managed by outpatients are appropriately staffed and to evaluate trusts' adherence to the objectives outlined in the Long Term Plan. METHOD: A freedom of information (FOI) request was sent in January 2023 to 153 trusts across Great Britain (time span: 1 January 2022-31 December 2022). Parameters requested included number of outpatients seen/discharged, phlebotomy episodes, number of sites/wards covered by phlebotomy, target/actual did not attend (DNA) rates, time since inception of the outpatient transformation project (OTP), advice and refer (A&R) and patient-initiated follow-up (PIFU), phlebotomy and outpatient managerial establishment and use of electronic notes and patient portals. RESULTS: A total of 117 trusts (76.5%) provided responses to the FOI request. The mean number of new outpatients seen face-to-face was 185,810. Of 73 trusts reporting both actual and target DNA rates, 62 (84.9%) did not meet their DNA targets. The actual DNA rate was significantly greater than the target DNA rate across trusts (p < 0.001, mean: 8.8% vs. 6.5%, respectively). A total of 58 different electronic systems and 29 patient portals were utilised across trusts. Thirty-six trusts (30.3%) did not have an outpatient transformation project manager and 16 trusts (13.7%) did not initiate an OTP. With phlebotomy provision, the mean number of outpatient phlebotomy episodes was lower than inpatient episodes (83,383 vs. 91,020, respectively). CONCLUSION: There are deficiencies in current outpatient establishments that may hinder the achievement of objectives set in the NHS Long Term Plan. Changes at all levels of healthcare are required, with increased reliance on technologies and investment in support for transformation management.
RESUMEN
Introduction: Hypermobility describes the movement of joints beyond normal limits. Whether hypermobility predisposes to patellar instability is yet to be established. We aimed to determine if joint hypermobility leads to an increased risk of patellar instability, and to evaluate outcomes of treatment for patellar instability in those who exhibit hypermobility. Methods: Published and unpublished literature databases were searched to September 7, 2023. Studies comparing prevalence of patellar dislocation/differences in treatment outcomes in patients with and without hypermobility were included. Results: We identified 18 eligible studies (4,391 patients). The evidence was low in quality. A case series on 82 patients found that there was a relationship between generalised joint laxity and patellar instability. This was corroborated by a study comparing 104 patients with patellar dislocation to 110 patients without. Prevalence of generalised joint laxity was six time higher in the former (64.4% vs 10.9%, p < 0.001).Five studies found surgical intervention aimed at correcting patellar dislocation in patients with idiopathic hypermobility led to satisfactory outcomes. There was conflicting evidence regarding if hypermobile patients have worse outcomes than non-hypermobile patients following medial patellofemoral ligament reconstruction (MPFLR) in two studies. In addition, this procedure had a 19.1% failure rate in patients with Ehlers Danlos Syndrome (EDS), with hypermobility associated with a higher failure rate (p = 0.03). One study showed the type of graft used made no difference in outcome scores or re-dislocation rates (p > 0.5). Another study had 7/31 (22.6%) autografts which failed, compared to 2/16 allografts (12.5%) (p = 0.69). Conclusion: Joint hypermobility is a risk factor for patellar instability. Identification of at-risk groups may aid prevention of dislocations and allow for appropriate treatment. Patients with EDS experience poor outcomes following patellar stabilization surgery, with post-operative monitoring required.
RESUMEN
BACKGROUND: Children and adolescents have the highest incidence of patellar instability among the population. We aimed to identify patho-morphological and epidemiological factors associated with patellar instability, and to identify factors predisposing to recurrence in children and adolescents. METHODS: Published and unpublished literature databases, conference proceedings and the reference lists of included studies were searched to the 14th of March 2024. Studies were eligible if they compared history characteristics, examination features and radiological parameters between patients with and without instability, or evaluated risk factors for instability recurrence. A random-effects meta-analysis was performed. Included studies were appraised using tools respective of study design. RESULTS: The evidence was moderate to low in quality. Forty-five studies (including 9000 patients) were eligible. Tibial tubercle - tibial groove (TT-TG) distance (weighted mean difference [WMD] 5.96 mm, 95% Confidence Interval [CI]: 4.94 to 6.99 mm), sulcus angle (WMD: 13.93Ë, 95% CI: 9.1Ë to 18.8Ë), and Insall-Salvati index (WMD: 0.2, 95% CI: 0.16 to 0.23) were greater in patients with patellar instability. Risk factors for recurrent dislocation included age less than 18 years (Odds ratio [OR]: 2.56, 95% CI: 1.63 to 4.0), skeletal immaturity (OR: 1.79, 95% CI: 1.21 to 2.64) and presence of trochlear dysplasia (OR: 3.37, 95% CI: 1.85 to 6.15). CONCLUSION: Knowledge of patho-morphological factors associated with patellar instability could help explain its pathophysiological processes, allowing for the design of treatment approaches and the identification of patients at risk.

Gaucher disease (GD) is a heterogeneous condition requiring tailored treatment approaches. The aim of this systematic review was to synthesise and evaluate current evidence pertaining to the use of Ambroxol for the treatment of GD. Published and unpublished literature databases, conference proceedings and the reference lists of included studies were searched until 23 November 2023. A narrative synthesis was performed. Database search and risk of bias assessment were performed independently by two reviewers. Twenty-one studies (182 patients) were included. The evidence was low in quality. Variable responses to Ambroxol were observed. Response rates were 36% and 55% in two studies reporting on type 1 GD. One study found a 22% response rate in type 2 GD, whereas another study found 29% of patients with type 3 GD reported neurological improvements. No severe adverse events were reported in the literature, with mild and reversible side effects reported. Varying response rates are to be expected (29%-100%) when treating neurological manifestations. Varying degrees of symptomatic improvement for the treatment of GD were noted in the literature. Multidisciplinary team input and clinical judgement are advised to provide personalized treatment of this complex and multi-faceted condition.
RESUMEN
PURPOSE: Outcomes of hip fractures in centenarians remain underreported owing to the small number of patients reaching 100 years of age. This review aimed to determine outcomes of hip fracture in centenarians and to identify the most common comorbidities among centenarians with hip fracture to better characterise this population. METHODS: Published and unpublished literature databases, conference proceedings and the reference lists of included studies were searched to the 25th of January 2023. A random-effects meta-analysis was performed. Included studies were appraised using tools respective of study design. RESULTS: Twenty-three studies (6970 centenarians) were included (retrospective period: 1990-2020). The evidence was largely moderate to low in quality. One-year mortality following a hip fracture was 53.8% (95% CI 47.2 to 60.3%). Pooled complication rate following a hip fracture in centenarians was 50.5% (95% CI 25.3 to 75.6%). Dementia (26.2%, 95% CI 15.7 to 38.2%), hypertension (15.6%, 95% CI 3.4 to 33.1%), and diabetes (5.5%, 95% CI 1.9 to 10.7%) were the most common comorbidities among centenarians with hip fracture. CONCLUSION: Hip fractures in centenarians typically involve complex patient presentations with diverse comorbidities. However, the current evidence-base is moderate to low in quality. Effective cross-discipline communication and intervention is suggested to promote treatment outcomes.

Introduction: Patellar instability can arise from a traumatic event with anatomical predisposing factors increasing the risk of dislocation. Accurate diagnosis is required to initiate appropriate treatment. We aimed to evaluate the patella apprehension test (PAT) as a method to diagnose patellar instability. Methods: The PRISMA diagnostic test accuracy checklist was followed. The review protocol was registered on PROSPERO with registration number CRD42022357898. Electronic databases, currently registered studies, conference proceedings and the reference lists of included studies were searched. A narrative synthesis evaluated the validity of the PAT as a method of diagnosing patellar instability. Results: A total of 4867 records were screened in the initial search. Of these, 34 articles satisfied the inclusion criteria, assessing 1139 knees of 1046 patients. The PAT was found to have a high sensitivity and specificity. Its intra and inter-rater reliability was highly variable among studies. Studies reporting patellar instability correction following surgery also found a decrease in the number of patients exhibiting a positive PAT. Conclusion: Current evidence suggests that the PAT has a high sensitivity and specificity. The intra- and inter-rater validities of the PAT are widely variable due to its subjective nature. Thus, though the PAT can be used to provide a provisional clinical diagnosis of patellar instability, formal functional assessment and imaging should be performed to confirm the diagnosis. Further research should explore the association between a positive PAT and anatomical parameters. In addition, studies comparing the accuracy of the PAT and radiological investigations should be performed.
RESUMEN
BACKGROUND: Hoffa's fat pad syndrome has been defined as impingement of Hoffa's fat pad, leading to oedema and fibrosis. The primary aim of this systematic review was to identify morphological differences in Hoffa's fat pad between patients with and without Hoffa's fat pad syndrome, evaluating them as risk factors predisposing to its development. The secondary aim was to summarize and evaluate current evidence pertaining to the management of Hoffa's fat pad syndrome. MATERIALS AND METHODS: The protocol for this review was prospectively registered (PROSPERO registration: CRD42022357036). Electronic databases, currently registered studies, conference proceedings and the reference lists of included studies were searched. All studies evaluating differences in Hoffa's fat pad anatomy under imaging between patients with and without Hoffa's fat pad syndrome were included, as well as those exploring epidemiological factors predisposing to its development (ethnicity, employment status, sex, age and BMI), and studies reporting on the effect of treatment on Hoffa's fat pad morphology. RESULTS: A total of 3871 records were screened. Twenty one articles satisfied the inclusion criteria, evaluating 3603 knees of 3518 patients. Patella alta, increased tibial tubercle-tibial groove distance, and increased trochlear angle were found to predispose the development of Hoffa's fat pad syndrome. Trochlear inclination, sulcus angle, patient age and BMI were not associated with this condition. The link between Hoffa's fat pad syndrome and ethnicity, employment, patellar alignment, Hoffa's fat pad composition, physical activity and other pathological processes cannot be established due to lack of evidence. No studies reporting on treatment for Hoffa's fat pad syndrome were identified. Though weight loss and gene therapy may provide symptomatic relief, further research is required to corroborate these claims. CONCLUSION: Current evidence suggests that high patellar height, TT-TG distance, and trochlear angle predispose the development of Hoffa's fat pad syndrome. In addition, trochlear inclination, sulcus angle, patient age and BMI do not seem to be associated with this condition. Further research should explore the link between Hoffa's fat pad syndrome and sport as well as other conditions pertaining to the knee. In addition, further study evaluating treatment approaches for Hoffa's fat pad syndrome is required.
RESUMEN
BACKGROUND: The infrapyloric artery (IPA) supplies the pylorus and the large curvature of the antrum. Its common origin points include the gastroduodenal artery (GDA) and right gastroepiploic artery (RGEA). The prevalence of variations in IPA origins can be of interest to gastric cancer surgeons who wish to increase their understanding of this vessel. The primary aim of this study was to perform a systematic review and meta-analysis on the origin of the IPA. The secondary aims were to assess imaging identification accuracy, to identify IPA morphological features, and to explore the relationship of IPA origin and clinicopathological characteristics. METHODS: Electronic databases, currently registered studies, conference proceedings and the reference lists of included studies were searched through March 2023. There were no constraints based on language, publication status, or patient demographics. Database search, data extraction and risk of bias assessment were performed independently by two reviewers. The point of origin of the IPA was the primary outcome. Secondary outcomes were imaging identification accuracy, relationship between IPA origin and clinicopathological characteristics, and IPA morphological features. A random-effects meta-analysis of the prevalence of different IPA origins was conducted. Secondary outcomes were narratively synthesized given the heterogeneity of studies reporting on these. RESULTS: A total of 7279 records were screened in the initial search. Seven studies were included in the meta-analysis, assessing 998 patients. The IPA arose most frequently from the anterior superior pancreaticoduodenal artery (ASPDA), with a pooled prevalence of 40.4% (95% CI 17.1-55.8%), followed by the RGEA with a pooled prevalence of 27.6% (95% CI 8.7-43.7%), and the GDA with a pooled prevalence of 23.7% (95% CI 6.4-39.7%). Cases of multiple IPAs had a pooled prevalence of 4.9% (95% CI 0-14.3%). The IPA was absent in 2.6% (95% CI 0-10.3%) of cases and arose from the posterior superior pancreaticoduodenal artery (PSPDA) in the remaining 0.8% (95% CI 0 - 6.1%). Distance between the pylorus and the proximal branch of the IPA and distance from the pylorus to the first gastric branch of the RGEA when the IPA originated from the ASPDA and RGEA were longer than when the IPA originated from the GDA. The IPA is a small vessel (<1 mm), and its origin is not related to clinicopathological characteristics including patient sex, age, and tumor stage and location. CONCLUSIONS: Surgeons must be aware of the most common origin points of the IPA. Recommendations for future study include the stratification of IPA origin according to demographic characteristics, and further investigation into IPA morphological parameters such as tortuosity, course and relation to adjacent lymph nodes, aiding the creation of a standardized classification system pertaining to the anatomy of this vessel.

BACKGROUND: Medial patellofemoral ligament (MPFL) reconstruction is a common surgical procedure for treating patellar instability. The primary aim of this systematic review was to determine whether MPFL reconstruction (MPFLR) leads to femoral tunnel enlargement (FTE). The secondary aims were to explore the clinical effects and risk factors of FTE. Electronic databases (MEDLINE, Global Health, Embase), currently registered studies, conference proceedings and the reference lists of included studies were searched independently by three reviewers. There were no constraints based on language or publication status. Study quality assessment was conducted. 3824 records were screened in the initial search. Seven studies satisfied the inclusion criteria, evaluating 380 knees in 365 patients. Rates of FTE following MPFLR ranged from 38.7 to 77.1%. Five low quality studies reported FTE did not lead to detrimental clinical outcomes as assessed with the Tegner, Kujala, IKDC, and Lysholm scores. There is conflicting evidence regarding change in femoral tunnel width over time. Three studies (of which two had a high risk of bias) reported age, BMI, presence of trochlear dysplasia and tibial tubercle-tibial groove distance did not differ between patients with and without FTE, suggesting these are not risk factors for FTE. CONCLUSION: FTE is a common postoperative event following MPFLR. It does not predispose poor clinical outcomes. Current evidence lacks the ability to identify its risk factors. The reliability of any conclusions drawn is hindered by the low level of evidence of the studies included in this review. Larger prospective studies with long-term follow up are required to reliably ascertain the clinical effects of FTE.
RESUMEN
PURPOSE: The right gastric artery (RGA) supplies the lesser curvature of the stomach. The prevalence of variations in RGA origins can be of interests to students, surgeons, and radiologists who wish to increase their understanding of this vessel. The aim of this study was to perform a systematic review and meta-analysis on the origin of the RGA. METHODS: The PRISMA 2020 checklist was followed. Electronic databases, currently registered studies, conference proceedings and the reference lists of included studies were searched. There were no constraints based on language or publication status. Database search, data extraction and risk of bias assessment were performed independently by two authors. A random-effects meta-analysis of the prevalence of different RGA origins was conducted. RESULTS: A total of 9084 records were screened in the initial search. Fifteen studies were included, assessing 1971 right gastric arteries. The RGA arose most frequently from the Proper Hepatic Artery (PHA), with a pooled prevalence of 53.6% (95% CI 44.5-60.8%), followed by the Left Hepatic Artery (LHA) with a pooled prevalence of 25.9% (95% CI 18.6-32.8%), and the Gastroduodenal Artery (GDA) with a pooled prevalence of 8.89% (95% CI 4.62-13.9%). Less common origins were the Common Hepatic Artery (CHA) (6.86%, 95% CI 3.15-11.5%), the Right Hepatic Artery (RHA) (3.43%, 95% CI 0.93-7.04%), and Middle Hepatic Artery (MHA) (1.31%, 95% CI 0-3.44%). CONCLUSIONS: This meta-analysis provides an accurate estimate of the prevalence of different RGA origins. Anatomical knowledge combined with pre-operative planning and imaging can prevent iatrogenic injury during surgery.

The purpose of this review was to summarize and compare the efficacy among surgical interventions in terms of symptomatic relief in patients with interstitial cystitis/bladder pain syndrome (IC/BPS). The review protocol was published on PROSPERO. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2020 checklist was followed. Following database search, a narrative synthesis was performed. Data pertaining symptom scores, pain levels, and voiding frequency following surgery were summarized by calculating percentage change in these parameters. Multiple surgical treatments were identified. These included injections of hyaluronic acid (HA), botulinum toxin A (Botox A), triamcinolone, resiniferatoxin (RTX), platelet-rich plasma, and 50% dimethyl sulfoxide (DMSO) solution, neuromodulation, hydrodistension (HD), resection/fulguration of Hunner lesions, resection of ilioinguinal and iliohypogastric nerves, reconstructive surgery, and cystectomy. This review found no evidence suggesting that HD and RTX injections can ameliorate IC/BPS symptoms. Current evidence suggests that sacral neuromodulation, cystectomy, and transurethral resection/fulguration of Hunner lesions could lead to symptomatic relief in IC/BPS. Further research into the efficacy of Botox A, triamcinolone, 50% DMSO solution, and HA instillations is required. However, the best treatment options cannot be reliably stated due to the low level of evidence of the studies identified. Further research should report outcomes for Hunner-type IC and BPS separately given their differing histopathological characteristics. Performing high-quality randomized controlled trials could be hindered by the low prevalence of the condition and a small proportion of patients progressing to surgery.
