Arthroscopy or arthrotomy for native knee septic arthritis: A systematic review.

Purpose: Septic arthritis of any joint is an orthopaedic emergency which requires prompt diagnosis and treatment. The knee is the commonest joint afflicted, and the primary objective of any treatment is complete source control. This commonly takes the form of antibiotic therapy and a washout of the infected joint by means of arthroscopy or arthrotomy. The primary aim of this review is to investigate if arthroscopic washout for native knee septic arthritis confers a lower risk of repeat procedure than arthrotomy. Methods: A systematic review and meta-analysis was conducted of the MEDLINE, SCOPUS and the Cochrane Library data bases. The primary outcome of interest was requirement for repeat washout with all-cause complications, length of inpatient stay and mortality secondary outcomes. Results: A total of 17,140 subjects were included for analysis of the primary outcome, and the overall rate of repeat procedure was 14.6%. No statistical difference was found between arthroscopy and arthrotomy for repeat washout (risk ratio 0.86 [95% confidence interval, CI: 0.72-1.02], I 2 = 36%). Eligible studies found in favour of arthroscopy for all-cause complication rate (risk ratio 0.75 [95% CI: 0.6-0.93], I 2 = 84%) and length of stay in hospital (mean difference -1.98 days [95% CI: -3.43 to -0.53], I 2 = 84%). No statistical difference was found for the mortality rate (risk ratio 1.17 [95% CI: 0.52-2.63], I 2 = 57%). Conclusion: Our analysis found arthroscopy and open arthrotomy to be equivocal for repeat surgical washout in native knee septic arthritis. All-cause complication rate and length of inpatient stay were favourable for arthroscopy with no difference noted between mortality rates. Level of Evidence: Level III.

Trends in the surgical management of proximal humerus fractures in Ireland from 2009 to 2022: An increasing usage of reverse shoulder arthroplasty.

BACKGROUND: Proximal humeral fractures are a common injury accounting for a significant workload across orthopaedic departments. Though often managed non-operatively, surgical management is indicated for a proportion of patients. AIMS: The aim of this study is to examine the trends in the management of proximal humeral fractures within Ireland over the past 13 years. METHODS: A retrospective review of Irish Hospital In-Patient Enquiry (HIPE) data was performed between January 2009 and December 2022. Information regarding demographics including age and gender, along with procedure type were collated after patients with proximal humerus fractures, were identified using relevant ICD 10 codes. RESULTS: Demographic details remained stable with females and those within the 55-69 year age bracket accounting for the highest proportion of patients. The mean annual number of procedures performed across the study period was 365 (273-508), with an increase from 288 cases in 2009 to 441 in 2022. Open reduction and internal fixation were the most common procedures accounting for 76.4% of cases. There has been a rising usage of total shoulder arthroplasty for fixation with an increase from < 5 cases in 2016 to 84 in 2022. A decrease in the usage of hemiarthroplasty and closed reduction internal fixation was also observed. CONCLUSIONS: There has been an increasing volume of operatively managed proximal humeral fractures in Ireland, which sustained despite the 2015 publication of the highly publicised PROPHER trial. The increasing utilisation of total shoulder arthroplasty in acute trauma management is notable and necessitates appropriate training for trauma theatre personnel.

Acetabular cup size trends in total hip arthroplasty.

BACKGROUND: Total hip arthroplasty (THA) is a common procedure for end stage osteoarthritis. The learning curve for THA is complex and challenging. One of the most difficult skills to master is acetabular reaming. We wish to identify if experience in arthroplasty leads to preservation of more bone stock. AIM: To investigate if increasing surgeon experience will predict an ever decreasing acetabular cup size. METHODS: A retrospective case series of four attending orthopaedic surgeons was completed. All uncemented elective total hip arthroplasties since appointment were selected for inclusion. The size of acetabular cup used was noted and logistic regression was used to identify if a trend to smaller cups existed. RESULTS: A total of 1614 subjects were included with a mean age of 64 years. Overall cups were on average 0.18mm smaller per year (95% confidence interval -0.25 to -0.11, P < 0.001). Individual surgeon trends showed cup sizes to decrease 0.27 mm/year for surgeon A, 0.02 mm/year for surgeon B, 0.15 mm/year for surgeon C and 0.29 mm/year for surgeon D. Three of the four surgeons had a more pronounced trend to smaller cups for male subjects than their female counterparts. CONCLUSION: We found increasing surgeon experience to be associated with an ever-decreasing acetabular cup size. Smaller acetabular cup size may act as a surrogate marker of surgical proficiency by virtue of decreased acetabular reaming.

Is the increased use of intramedullary nailing over DHS for intertrochanteric hip fractures justified? - A review of the Irish hip fracture database 2016 -2020.

PURPOSE: Intertrochanteric hip fractures are significant and costly injuries and there remains controversy within the orthopaedic literature over the best method of fixation. The Irish Hip Fracture Database (IHFD) was established in 2012 to drive improvements in clinical outcomes and the quality of hip fracture care. This paper will review the outcomes of dynamic hip screw (DHS) versus intra-medullary nailing (IMN) in the treatment of intertrochanteric hip fractures in Ireland. METHODS: Eligible cases for this study include patients >60 years of age with trochanteric hip fractures treated by DHS or IMN between January 2016 and December 2020. Outcomes recorded and compared include length of stay, inpatient mortality, mobilisation on post-operative day 1 (POD 1), and discharge destination. RESULTS: 5668 hip fractures treated with DHS or IMN were identified. There was no significant difference between inpatient mortality, re-operation rate or length of stay between the two groups. Females and patients with a high ASA grade (IV and V) were more likely to receive IMN. Patients receiving DHS were more likely to be mobilised day 1 post-operatively and be discharged directly home. It was noted that the use of IMN increased from 42% of cases in 2016 to 70% in 2020. CONCLUSION: IMN use for intertrochanteric fractures continues to increase. However, patients treated with DHS were more likely to mobilise early post-operatively and to go directly home. Notwithstanding the limitations of national registry data research, the dramatic rise in the use of IMN for these fractures appears unsupported by the evidence.

Intracapsular hip fractures: A comparative study of cemented and uncemented hemiarthroplasties in the Irish hip fracture database.

BACKGROUND: The aim of this study was to analyse the association between use of cement for stem fixation in hip hemiarthroplasty and the outcomes of mobility, mortality, and discharge destination. METHODS: The Irish Hip Fracture Database was examined from 2016 to 2020 to assess for any difference in post op mobility, 7-day, 14-day and inpatient mortality, and discharge destination. RESULTS: A total of 7109 hemi-arthroplasties were identified from 2016 to 2020. 71.6 % were cemented (n = 5,172), with 28.4 % uncemented (1,937). There was no difference in day 1 post op mobilisation (79.7 % vs 80.9 %) or cumulative ambulatory score on discharge (2.5 vs 2.4). The mortality rate was equivocal at all time points between the cemented and uncemented groups (7 day (.9 % vs 1.2 %), 14 day (1.9 % vs 2.3 %), inpatient (4 % vs 5.1 %)). There was no difference in length of stay (11 vs 12 days) or discharge to home directly (21 % vs 27 %). CONCLUSION: The use of cement did not have any significant difference on post op mortality, mobility or discharge destination.

Kocuria rhizophila prosthetic hip joint infection.

We present the first case report of prosthetic joint infection (PJI) caused by Kocuria rhizophila. Our patient is a 74-year-old male who underwent primary total hip replacement for right hip pain. His recovery was uneventful until 6 weeks postoperatively when he presented to his routine outpatient appointment with significant erythema, swelling, and tenderness over his right hip wound. Based on the acuity of his symptoms and the radiological findings, it was determined that the patient should undergo debridement, antibiotics, and implant retention (DAIR procedure). A consensus decision was also made at our PJI multidisciplinary meeting to treat him with 12 weeks of IV antibiotics. After completing this 12 weeks course of IV Vancomycin, his inflammatory markers returned to normal limits. At 6 months follow-up, our patient was mobilizing independently without any signs of infection recurrence. His radiographs showed the implant was in a satisfactory position with no evidence of loosening. This case adds to an emerging body of literature describing invasive infections associated with Kocuria species. We have demonstrated the effectiveness of managing this condition with debridement, implant retention, and IV Vancomycin therapy for 12 weeks.

Sustainable orthopaedic surgery: Initiatives to improve our environmental, social and economic impact.

In response to appeals from the WHO and The Lancet, a collaborative statement from over 200 medical journals was published in September 2021, advising international governments to combat the "catastrophic harm to health" from climate change. Healthcare, specifically surgery, constitutes a major contributor to environmental harm that remains unaddressed. This article provides practical guidance that can be instituted at a departmental, hospital and national level to institute transformative, sustainable efforts into practice. We also aim to provoke healthcare leaders to discuss policy-making with respect to this issue and highlight the necessity for sustainability to become a core domain of quality improvement. The average orthopaedic service produces 60% more waste than any other surgical specialty. Fortunately, simple measures such as a comprehensive education programme can decrease waste disposal costs by 20-fold. Other simple and effective "green" measures include integrating carbon literacy into surgical training, prioritising regional anaesthesia and conducting recycling audits. Furthermore, industry must take accountability and be incentivised to limit the use of single-item packaging and single-use items. National policymakers should consider the benefits of reusable implants, reusable surgical drapes and refurbishing crutches as these are proven cost and climate-effective interventions. It is crucial to establish a local sustainability committee to maintain these interventions and to bridge the gap between clinicians, industry and policymakers.

Distal radius fracture fixation using WALANT versus general and regional anesthesia: A systematic review and meta-analysis.

BACKGROUND: WALANT (wide-awake local anaesthetic no tourniquet) has become a popular technique in upper limb surgery including distal radius fracture fixation. The purpose of this systematic review and meta-analysis is to assess the effectiveness of the WALANT technique in distal radius fracture fixation, and to compare it to both general and regional anaesthesia. METHODS: Pubmed, Embase, and Scopus databases were searched on 26/06/21 according to the PRISMA guidelines with the following search terms: radius, WALANT, "local anesthetic", wide-awake surgery. All studies comparing WALANT with other forms of anaesthesia for distal radius fracture fixation were included. RESULTS: 110 articles were identified, six studies (410 patients) were included, 164 of these patients were in the WALANT group. Two patients (1.2%) in the WALANT group and seven (6.5%) in the regional anaesthesia group required conversion to general anaesthesia. There was no statistically significant difference in post-operative complications, intra-operative VAS pain scores, operative times, functional or radiological outcomes. A statistically significant 8.6 mls increase in pooled mean blood loss in the WALANT group was noted (p = 0.02) although the clinical significance of this is doubtful. CONCLUSION: The WALANT technique for distal radius fracture fixation is non-inferior to regional and general anaesthesia. It is a safe and effective technique that surgeons may consider utilising, especially for patients not suitable for general anaesthetic or in centres in which there is a lack of access to specialist anaesthetic equipment and care.

Increasing hip fracture volume following repeated lockdowns: an Irish multicentre study of periods pre-Covid, during Covid lockdown and following vaccination.

BACKGROUND: Older age groups were identified as a high-risk cohort for Covid-19 and thus were a focus of lockdown measures enacted internationally. Resultant decreased social mobility and physical activity levels are associated with sarcopenia, which may lead to increased risk of hip fracture upon resuming social integration and physical activities after easing of lockdown restrictions. AIMS: Our aim was to compare the incidence of hip fractures during the period following vaccination with subsequent relaxation of restrictions, to those prior to and during the Covid pandemic. METHODS: A multicentre retrospective cohort study was performed consisting of all patients presenting with a "hip" fracture to 3 regional trauma units over the relevant time periods in 2019, 2020 and 2021. Tallaght, Galway and Waterford University Hospitals are large academic teaching hospitals with a combined mixed urban and rural catchment of over 1 million people. FINDINGS: Four-hundred-fourteen patients in total were included in the final analysis, with 133 eligible hip fractures observed proceeding to operative treatment across the study period in 2019, 132 in 2020 and 149 in 2021, representing a 12.88% increase. Demographic data revealed similar patient cohorts with respect to age and gender, fracture pattern and treatment. CONCLUSIONS: An increase in hip fracture volume was observed during the period post vaccination with subsequent relaxation of restrictions and increased social mobility, compared to those prior to and during the Covid pandemic. These findings have implications for hospital planning and orthopaedic resourcing as we navigate our way forward past the Covid-19 Pandemic.

Telemedicine in Orthopedic Surgery: A Systematic Review of Current Evidence.

Introduction: The coronavirus disease 2019 (COVID-19) pandemic has triggered transformative changes in how clinicians interact with patients. There has been a shift toward virtual consultations. The evidence to support this change in practice is unclear. The aim of this study was to systematically review the evidence base for virtual consultations for orthopedics. Materials and Methods: Two independent reviewers performed a literature search based on Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, utilizing the MEDLINE, EMBASE, and Scopus databases. Only studies reporting outcomes following the use of telemedicine for diagnosis, consultation, rehabilitation, and follow-up were included. Outcomes analyzed were: (1) patient and clinician satisfaction, (2) clinical outcome measures, and (3) cost analysis of traditional versus teleconsultation. Results: A total of 41 studies were included. Fifteen studies compared clinical outcomes of telemedicine against a matched traditional cohort. Of these 15 studies, 2 demonstrated noninferiority, 9 showed no statistically significant difference, and 4 found telemedicine to be superior. Eleven studies recorded patient reported outcomes, which demonstrated high patient satisfaction. Nine studies reported decreased costs when telemedicine was compared to traditional care. The remaining six studies had varied aims and methodologies that didn't fit well with any of these subheadings. Discussion: While the available evidence is limited, the studies assessed here show that telemedicine can deliver high quality health care with good clinical outcomes and high patient satisfaction in a cost-effective manner. Our team thinks what this has highlighted is that communication technology is advancing rapidly and that we as a community of surgeons need to be able to adapt rapidly and adopt innovative technology to continue to improve patient experience and outcomes.

Is postoperative non-weight-bearing necessary? INWN Study protocol for a pragmatic randomised multicentre trial of operatively treated ankle fracture.

BACKGROUND: Postoperative management regimes vary following open reduction and internal fixation (ORIF) of unstable ankle fractures. There is an evolving understanding that extended periods of immobilisation and weight-bearing limitation may lead to poorer clinical outcomes. Traditional non-weight-bearing cast immobilisation may prevent loss of fixation, and this practice continues in many centres. The purpose of this trial is to investigate the safety and efficacy of immediate weight-bearing (IWB) and range of motion (ROM) exercise regimes following ORIF of unstable ankle fractures with a particular focus on functional outcomes and complication rates. METHODS: A pragmatic randomised controlled multicentre trial, comparing IWB in a walking boot and ROM within 24 h versus non-weight-bearing (NWB) and immobilisation in a cast for 6 weeks, following ORIF of all types of unstable adult ankle fractures (lateral malleolar, bimalleolar, trimalleolar with or without syndesmotic injury) is proposed. All patients presenting to three trauma units will be included. The exclusion criteria will be skeletal immaturity and tibial plafond fractures. The three institutional review boards have granted ethical approval. The primary outcome measure will be the functional Olerud-Molander Ankle Score (OMAS). Secondary outcomes include wound infection (deep and superficial), displacement of osteosynthesis, the full arc of ankle motion (plantar flexion and dorsal flection), RAND-36 Item Short Form Survey (SF-36) scoring, time to return to work and postoperative hospital length of stay. The trial will be reported in accordance with the CONSORT statement for reporting a pragmatic trial, and this protocol will follow the SPIRIT guidance. DISCUSSION: Traditional management of operatively treated ankle fractures includes an extended period of non-weight-bearing. There is emerging evidence that earlier weight-bearing may have equivocal outcomes and favourable patient satisfaction but higher wound-related complications. These studies often preclude more complicated fracture patterns or patient-related factors. To our knowledge, immediate weight-bearing (IWB) following ORIF of all types of unstable ankle fractures has not been investigated in a controlled prospective manner in recent decades. This pragmatic randomised-controlled multicentre trial will investigate immediate weight-bearing following ORIF of all ankle fracture patterns in the usual care condition. It is hoped that these results will contribute to the modern management of ankle fractures. TRIAL REGISTRATION: ISRCTN Registry ISRCTN76410775 . Retrospectively registered on 30 June 2019.

Short-term outcomes of total knee arthroplasty performed with and without a tourniquet.

INTRODUCTION: Not using a tourniquet could improve early postoperative pain, range of motion (ROM), length of stay (LOS), and thromboembolic risk in patients undergoing total knee arthroplasty (TKA). Our aim was to compare these factors, intraoperative blood loss, and gender-related outcomes in patients undergoing primary TKA with or without a tourniquet. METHODS: We performed a retrospective cohort study of 97 patients undergoing TKA with or without tourniquet from 2018 to 2020. Revisions and bilateral TKAs were excluded. Blood loss was estimated using a validated formula. Postoperative pain was tested using the visual analogue scale (VAS). ROM and quadriceps lag were assessed by a physiotherapist on a postoperative day 2 and discharge. The index of suspicion for a thromboembolic event was defined as the number of embolic-related investigations ordered in the first 6 months post-surgery. The Shapiro-Wilk test was used to assess the distribution of the data, Mann-Whitney for the continuous variables, and Fischer's test for the categorical ones. RESULTS AND DISCUSSION: There was a significant difference in blood loss. The non-tourniquet group lost on average 32% more blood (1291 mL vs. 878 mL, p<0.001 two-tailed). We found no difference in pain, ROM, LOS, and quadriceps lag on day 2 and at discharge. There was one thromboembolic event in the tourniquet group, but the thromboembolic index of suspicion did not differ (p=0.53). With tourniquet use, women had a significantly lower day 2 maximum flexion than men (71.56° vs. 84.67°, p=0.02). In this retrospective cohort study, the results suggest that tourniquet use is associated with lower blood loss and similar postoperative pain, range of motion, quadriceps lag, length of stay, and thromboembolic risk. There might be some differences between how men and women tolerate a tourniquet, with women having worse short-term outcomes compared to men.

Virtual Fracture Clinics in Orthopaedic Surgery - A Systematic Review of Current Evidence.

AIMS: Approximately 75% of fractures are simple, stable injuries which are often unnecessarily immobilised with subsequent repeated radiographs at numerous fracture clinic visits. In 2014, the Glasgow Fracture Pathway offered an alternative virtual fracture clinic (VFC) pathway with the potential to reduce traditional fracture clinic visits, waiting times and overall costs. Many units have implemented this style of pathway in the non-operative management of simple, undisplaced fractures. This study aims to systematically review the clinical outcomes, patient reported outcomes and cost analyses for VFCs. MATERIALS AND METHODS: Two independent reviewers performed the literature search based on PRISMA guidelines, utilizing the MEDLINE, EMBASE and COCHRANE Library databases. Studies reporting outcomes following the use of VFC were included. Outcomes analysed were: 1) clinical outcomes, 2) patient reported outcomes, and 3) cost analysis. RESULTS: Overall, 15 studies involving 11,921 patients with a mean age of 41.1 years and mean follow-up of 12.6 months were included. In total, 65.7% of patients were directly virtually discharged with protocol derived conservative management, with 9.1% using the Helpline and 15.6% contacting their general practitioner for advice or reassurance. A total of 1.2% of patients experienced fracture non-unions and 0.4% required surgical intervention. The overall patient satisfaction rate was 81.0%, with only 1.3% experiencing residual pain at the fracture site. Additionally, the mean cost per patient for VFC was £71, with a mean saving of £53 when compared to traditional clinic models. Subgroup analysis found that for undisplaced fifth metatarsal or radial head/neck fractures, the rates of discharge from VFC to physiotherapy or general practitioners were 81.2% and 93.7% respectively. DISCUSSION AND CONCLUSION: This study established that there is excellent evidence to support virtual fracture clinic for non-operative management of fifth metatarsal fractures, with moderate evidence for radial head and neck fractures. However, the routine use of virtual fracture clinics is presently not validated for all stable, undisplaced fracture patterns. LEVEL OF EVIDENCE: IV; Systematic Review of all Levels of Evidence.

A Systematic Review of Total Knee Arthroplasty in Neurologic Conditions: Survivorship, Complications, and Surgical Considerations.

BACKGROUND: Patients with neurologic disorders present a unique set of challenges for knee surgeons because of contractures, muscle weakness, spasticity, and ligament instability. The primary purpose of this review was to report the outcomes of total knee arthroplasty (TKA) in these patients, including survivorship, complications, and surgical considerations. METHODS: We performed a systematic review of articles using PubMed, Cochrane Central, EMBASE, and Google Scholar. All studies reporting outcomes of TKA in patients with Parkinson disease, multiple sclerosis, poliomyelitis, Charcot joint, spina bifida, stroke, and cerebral palsy were included. RESULTS: In total 38 studies were included: 22 studies (461 patients) reported patient-reported outcome measures and 24 studies (510 patients) reported survivorship. All 38 studies reported complication rates. TKA resulted in an improvement in functional outcome in all series. Complication rate was higher in patients with neurologic conditions. Of studies reporting survivorship, mean follow-up ranged from 1 to 12 years with survivorship from 66% to 100%. All levels of implant constraint were reported without consensus. Limited rehabilitative data exist. CONCLUSION: TKA in patients with neurologic disorders improves symptoms and function but carries significant risk. This review helps surgeons preoperatively counsel their patients in an informed manner. Careful planning, perioperative care, and appropriate implant selection may mitigate risk of complication.

A healthy decline in age- and sex- specific incidence of hip fractures in the elderly in the Republic of Ireland.

AIM: The number of patients sustaining hip fractures in the Republic of Ireland was expected to increase by 100% from 2004 to 2026. This has not been seen either in local or international literature. Our aim is to assess the age- and sex-specific incidence of hip fractures in patients over the age of 65 years and to determine whether the projected increase in incidence is mirrored in the reality of the Irish experience. METHODS: This is a retrospective observational cohort study including all patients with a hip fracture from a tertiary referral centre from 2005 to 2015. Population data was obtained from the Central Statistics Office of Ireland. RESULTS: 3818 hip fractures in the over 65 age group were recorded. The highest incidence of hip fractures occurred in the 85-90 year old age group. For all ages over 65, the incidence of hip fractures in females over the 10 year period is significantly reducing (p < 0.01). There were 955 hip fractures per 100,000 in females in 2010 and 410 per 100,000 in males. In 2014, this had reduced to 668 in females and 332 in males respectively. CONCLUSION: The annual hip fracture incidence has decreased across both sexes in this study period. This may be associated with preventative measures and introduction of fracture liaison services. This study highlights the importance of investment in preventative strategies for a continued reduction in hip fracture incidence and will help to plan future services.

Radial nerve injury following dry needling.

A 27-year-old secretary presented to an orthopaedic outpatients department with a 1-month history of left wrist drop following dry needling. On insertion of a needle, she reported spasms in her left hand followed by a wrist drop. An MRI scan was normal. Electromyogram and nerve conduction studies showed a neuropraxia of the left radial nerve. She was referred to a hand therapist for splinting and intensive hand therapy; however, her symptoms remain unchanged.

Fatigue fracture of tibial arthroplasty implant masked by contralateral knee arthritis.

INTRODUCTION: The wear of polyethylene components is a well-recognised long-term complication of total knee arthroplasty. PRESENTATION OF CASE: We present a case of fatigue fracture of a geomedic tibial tray 17 years after implantation. The symptoms were masked by primary osteoarthritis of the contralateral knee. DISCUSSION: The mode of failure in this case differs from that most commonly reported in the literature in that it occurred late as the result of prolonged use, not due to implant failure, physiological factors, or surgical technique. The case also demonstrates the incredible 'masking' effect of arthritic knee pain. CONCLUSION: This case highlights the importance to clinicians of keeping a high index of suspicion for prosthesis complications in patients with unilateral joint replacement with contralateral arthropathy.
