Does Surgeon Fellowship Training Influence Outcomes in Hemiarthroplasty for Femoral Neck Fracture?

Fellowship Training in Arthroplasty Improves Treatment Success of Debridement, Antibiotics, and Implant Retention for Periprosthetic Knee Infections

Background

Debridement, antibiotics, and implant retention (DAIR) is a well-accepted surgical strategy for periprosthetic joint infection (PJI) following total knee arthroplasty (TKA). DAIR in TKA may be incorrectly thought of as a "simple" procedure not requiring formal specialized training in arthroplasty. Currently, there are no studies comparing the risk of treatment failure based on surgeon fellowship training.

Methods

A retrospective review was performed of consecutive patients who underwent DAIR for TKA PJI at our institution. Two cohorts were created based on whether DAIR was performed by an arthroplasty fellowship-trained (FT) surgeon or nonarthroplasty fellowship-trained (NoFT) surgeon. Primary outcome was treatment failure following DAIR at a minimum of 1 year postoperatively. Treatment failure was based on the Tier 1 International Consensus Meeting definition of infection control. Secondary outcomes were also recorded including death during the totality of PJI treatment.

Results

A total of 112 patients were identified (FT = 68, NoFT = 44). At a mean follow-up of 7.3 years [standard deviation = 3.9], 73 patients (59.8%) failed treatment. Fellowship training in arthroplasty significantly improved treatment success rates (FT, 35/68 [51.5%]; NoFT, 10/44 [22.7%]; odds ratio 2.5 [95% confidence interval 1.1 to 5.9; P = .002]). Survivorship also differed significantly between the cohorts; at timepoints of 1.5 months, 5 months, 30 months, and 180 months, survivorship of the FT cohort was 79.4%, 67.6%, 54.4%, and 50.7%, respectively, compared with a survivorship of 65.9%, 52.3%, 25%, and 22.7% in the NoFT cohort (P = .002).

Conclusions

TKA PJI treated with DAIR should not be considered a simple procedure. Improved treatment success may be associated with subspecialty fellowship training in arthroplasty.

Traumaplasty: When and How to Perform Acute Arthroplasty for Fractures Around the Hip in the Elderly Patient

Acute fractures around the hip are prevalent injuries associated with potentially devastating outcomes. The growing utilization of arthroplasty for femoral neck fractures in the elderly is likely a result of improvements in reoperation rates and postoperative function. Compared to hemiarthroplasty, total hip arthroplasty is associated with a slight functional benefit that is unlikely noticeable for many patients, as well as minimal differences in complications and patient reported outcome measures. However, the evidence supporting cement use in femoral stem fixation is robust. Multiple high power randomized controlled trial-based studies indicate cement fixation brings more predictable outcomes and fewer reoperations. In the setting of acute acetabular fracture, total hip arthroplasty is a favorable approach for elderly patients and fracture patterns associated with increased risk of revision after open reduction and internal fixation. Variations in patient characteristics and fracture patterns demand careful consideration whenever selecting the optimal treatment. In fracture patient populations, comanagement is an important consideration when seeking to reduce complications and promote cost-effective quality care.

The influence of operation time for hip hemiarthroplasty on complication rates and mortality in patients with femoral neck fracture: a retrospective data analysis

BACKGROUND

The aim of the present study was to investigate the influence of various factors, in particular operation time, on mortality and complication rates in patients with femoral neck fractures who have undergone hip hemiarthroplasty (HHA) and to determine a cut-off value above which mortality and complication rates increase significantly.

METHODS

Cases of patients with femoral neck fracture treated with HHA between 1 January 2017 and 31 December 2023 were screened for eligibility. Multiple logistic regressions were calculated to determine which factors (patient age, experience of surgeon, patient sex, ASA score, time to surgery, operation time) influenced the incidence of complications and mortality. The exact cut-off value for complications and mortality was determined using the Youden index of the ROC curve (sensitivity vs. specificity) of logistic regression.

RESULTS

A total of 552 patients were considered eligible for this study. During the 90-day follow-up period after HHA, 50 deaths and 34 complications were recorded, giving a mortality rate of 9.1%, and a complication rate of 6.2%. Of the 34 complications recorded, 32.3% were infections, 14.7% dislocations, 20.7% trochanteric avulsions, 11.8% periprosthetic fractures, 11.8% nerve injuries, and 8.8% deep vein thrombosis. The odds ratio (OR) of a patient experiencing a complication is 2.2% higher for every minute increase in operation time (Exponential Beta - 1 = 0.022; p = 0.0363). The OR of a patient dying is 8.8% higher for each year increase in age (Exponential Beta - 1 = 0.088; p = 0.0007). When surgery was performed by a certified orthopaedic surgeon the mortality rate lowered by 61.5% in comparison to the surgery performed by a trainee (1 - Exponential Beta = 0.594; p = 0.0120). Male patients have a 168.7% higher OR for mortality than female patients (Exponential Beta - 1 = 1.687; p = 0.0017). Patients with an operation time of ≥ 86 min. have a 111.8% higher OR for mortality than patients with an operation time of < 86 min. (Exponential Beta - 1 = 1.118).

CONCLUSION

This retrospective data analysis found that the risk of a patient experiencing a complication was 2.2% higher for every minute increase in operation time. Patients with an operation time above the cut-off of 86 min had a 111.8% higher risk of mortality than those with an operation time below the cut-off. Other influencing factors that operators should be aware of include patient age, male sex, and operator experience.

Adult Reconstruction Surgeons Manage Patients With Higher Medical Complexities and Still Achieve Comparable Outcomes to Sports Medicine Surgeons Following Total Knee Arthroplasty

Background

Orthopaedic surgeons who are fellowship-trained in adult reconstruction (AR) specialize specifically in total joint arthroplasty, including total knee arthroplasty (TKA). However, TKA procedures are not only performed by AR surgeons. The purpose of this study was to compare the patient demographics and postoperative outcomes of patients who had a TKA procedure performed by an AR surgeon vs a sports medicine (SM) surgeon.

Methods

A retrospective cohort study was conducted using a national insurance database. Patients who underwent a primary elective TKA procedure by an AR surgeon (n = 56,570) and an SM surgeon (n = 72,888) were identified. Patient demographics, rates of joint complications within 2 years, and medical complications within 90 days postoperatively were compared using multivariable logistic regression.

Results

Compared to the cohort of patients undergoing TKA by SM surgeons, the patient cohort of AR surgeons had a higher mean Elixhauser comorbidity index (4.2 vs 4.0, P < .001), and had significantly higher rates of several comorbidities. Within 90 days, patients of AR surgeons demonstrated significantly lower rates of acute kidney injury and transfusions. When compared to patients of SM surgeons, patients of AR surgeons demonstrated significantly lower rate of manipulation under anesthesia or lysis of adhesions within 2 years. Rates of all other joint-related complications were statistically comparable between the 2 cohorts.

Conclusions

As a cohort, AR surgeons perform TKA on a higher-risk cohort of patients compared to sports medicine surgeons. Despite the higher-risk patient population, outcomes of TKA by AR surgeons appear equivalent compared to their SM colleagues.

Unveiling the Economic Toll of Surgical Learning Curve in Elderly Hip Fractures

Can the financial impact of implant choice during the learning curve of inexperienced surgeons in hip fracture surgery be quantified? Hip fractures in the elderly are a significant medical concern, often requiring surgical interventions performed by orthopedic surgery residents. As healthcare costs rise, exploring cost reduction opportunities within the healthcare system becomes crucial. In this prospective analysis, we examined the financial implications of implant choices encountered by residents during their learning curve in hip fracture surgery. Our study included 278 surgically treated pertrochanteric fractures using the same locking cephalomedullary nail. Data on patients, surgeons (including their experience and seniority), and all implants charged by the hospital were collected. This encompassed documentation of any nail-related equipment that was opened on the operating table and whether it was subsequently used by the end of the procedure. By calculating the number and cost of these implants, we assessed the financial burden associated with suboptimal choices made during the learning curve. Our findings revealed that in 16.18% of surgeries, instances of suboptimal implant utilization occurred, highlighting the complexities of the learning process. Importantly, the rate of these challenges was not influenced by surgeon seniority or patient characteristics. The mean additional cost per surgery was determined to be USD 65.69 ± 157.63 for surgeries with suboptimal implant utilization, compared to USD 56.55 ± 139.13 for surgeries without such challenges. Although there was a trend towards higher implant-related costs in resident-led surgeries, the difference did not reach statistical significance. These findings underscore the feasibility of enabling residents to autonomously perform intramedullary nailing surgeries, even without specialist supervision, while incurring minimal additional expenses during the learning curve. By acknowledging the financial implications associated with the learning curve in the management of hip fractures, we can strive to optimize healthcare costs, thus addressing an important aspect of this issue.

Total Hip Arthroplasty Learning Curves Based on Approach for New Fellowship-trained Surgeons

INTRODUCTION

There is concern that the direct anterior (DA) approach is associated with a steeper learning curve than the posterolateral (PL) approach in total hip arthroplasty (THA). The purpose of this study was to investigate if the learning curve is similar for newly trained arthroplasty fellowship-trained surgeons using the DA and PL approaches.

METHODS

The first 100 primary THA cases of six DA and PL fellowship-trained arthroplasty surgeons were identified and divided into 50 case cohorts. Demographics, indications for surgery, and 90-day Hip Society standardized complications were collected. Variables were analyzed using independent sample t tests, chi-square tests, or Fisher exact tests.

RESULTS

In total, there were 600 patients, and no notable differences were observed in revision surgeries, surgical complications, and total complications between the DA and PL groups. Both groups had lower revision surgery rates, surgical complications, and total complications during their second 50 cases. Higher revision surgeries, and surgical and total complication rates were observed among all surgeons during the first 50 cases.

DISCUSSION AND CONCLUSION

No differences were observed in the learning curve when comparing the DA and PL approach. With proper training, early-career surgeons can safely perform THA with similar complication rates regardless of the approach.

Complications of Hip Hemiarthroplasty

Hip hemiarthroplasty is a commonly performed orthopedic surgery, used to treat proximal femur fractures in the elderly population. Although hip hemiarthroplasty is frequently successful in addressing these injuries, complications can occur. Commonly seen complications include dislocation, periprosthetic fracture, acetabular erosion, and leg-length inequality. Less frequently seen complications include neurovascular injury and capsular interposition. This article presents a comprehensive review of the complications associated with the management of hip hemiarthroplasty. [Orthopedics. 2023;46(4):e199-e209.].

Comparison between Orthopaedic Trauma versus Arthroplasty Fellowship Training on Outcomes of Total Hip Arthroplasty for Femoral Neck Fracture

BACKGROUND

This study aimed to identify differences in patient characteristics, perioperative management methods, and outcomes for total hip arthroplasty (THA) for femoral neck fracture (FNF) when performed by orthopaedic surgeons who have arthroplasty versus orthopaedic trauma training.

METHODS

This study was a multicenter, retrospective review of 636 patients who underwent THA for FNF between 2010 and 2019. There were 373 patients who underwent THA by an arthroplasty surgeon, and 263 who underwent THA by an orthopaedic trauma surgeon. Comorbidities, management methods, and outcomes were compared between patients operated on by orthopaedic surgeons who had arthroplasty versus trauma training.

RESULTS

Arthroplasty-trained surgeons had shorter operative times (102 vs 128 minutes, P<0.0001) and utilized tranexamic acid more frequently than trauma-trained surgeons (48.8 vs 18.6%, P<0.0001). Orthopaedic trauma surgeons more frequently utilized an anterior approach. Patients of arthroplasty-trained surgeons had lower rates of complications including pulmonary embolism (1.6 vs 6.5%, P=0.0019) and myocardial infarction (1.6 vs 11.0%, P<0.0001). Similarly, patients of arthroplasty-trained surgeons were discharged faster (5.3 vs 7.9 days, P<0.0001) with greater ambulation capacity (92.2 vs 57.2 feet, P<0.0001). Dislocation, periprosthetic joint infection, and revision were similar between both groups. When adjusted for covariates, there was no difference in 90-day, 1-year, or 2-year mortality.

CONCLUSION

A THA performed for FNF by arthroplasty surgeons was associated with lower in-hospital morbidities and improved functional statuses at discharge. However, mortalities and complications after discharge were similar between both specialties when adjusted for confounding variables. Optimization of protocols may further improve outcomes for THA for FNF.

The Trauma Fellow's Perspective on Grit and Resilience and Its Role in Wellness

Purpose of Review

To describe the unique stressors of surgical training and fellowship and how grit and resilience influence trainee wellness.

Recent Findings

Surgical training is an intense, high-stress experience. For fellows-in-training, unique stressors are associated with this chapter of training, from financial pressors to the stress of job acquisition. Wellness is essential for surgical fellows, not just for the critical need for quality mental health of providers, but also for the patients who are also affected by provider burnout. There are various wellness programs that can be instituted nationally and institutionally to optimize fellow wellness, but one of the most high-yield foci for fellow wellness is focused mentorship, the key to assuring wellness and harnessing grit.

Summary

Surgical residency and fellowship are prodigiously demanding experiences, which mandate grit and resilience. It is imperative that widespread cultural and institutional changes take place to best support surgical trainees.

The National Provider Identifier Taxonomy: Does it Align With a Surgeon's Actual Clinical Practice?

INTRODUCTION

The taxonomy code(s) associated with each National Provider Identifier (NPI) entry should characterize the provider's role (e.g., physician) and any specialization (e.g., orthopedic surgery). While the intent of the taxonomy system was to monitor medical appropriateness and the expertise of care provided, this system is now being used by researchers to identify providers and their practices. It is unknown how accurate the taxonomy codes are in describing a provider's true specialization.

METHODS

Department websites of orthopedic surgery and general surgery from three large academic institutions were queried for practicing surgeons. The surgeon's specialty and subspeciality information listed was compared to the provider's taxonomy code(s) listed on the National Plan and Provider Enumeration System (NPPES). The match rate between these data sources was evaluated based on the specialty, subspecialty, and institution.

RESULTS

There were 295 surgeons (205 general surgery and 90 orthopedic surgery) and 24 relevant taxonomies (8 orthopedic and 16 general or plastic) for analysis. Of these, 294 surgeons (99%) selected their general specialty taxonomy correctly, while only 189 (64%) correctly chose an appropriate subspecialty. General surgeons correctly chose a subspecialty more often than orthopedic surgeons (70 versus 51%, P = 0.002). The institution did not affect either match rate, however there were some differences noted in subspecialty match rates inside individual departments.

CONCLUSIONS

In these institutions, the NPI taxonomy is not accurate for describing a surgeon's subspecialty or actual practice. Caution should be taken when utilizing this variable to describe a surgeon's subspecialization as our findings might apply in other groups.

Epidemiology and Management of Proximal Femoral Fractures in Italy between 2001 and 2016 in Older Adults: Analysis of the National Discharge Registry

This study aims to determine the annual incidence of proximal femoral fractures in Italy in the period between 2001 and 2016 among older adults, and to describe the trends in the clinical management of these cases. Data were retrieved from the National Hospital Discharge records issued by the Italian Ministry of Health and from the Italian Institute for Statistics. The number of hospitalizations increased between 2001 and 2016, while the age-adjusted yearly incidence decreased from 832.2 per 100,000 individuals to 706.2. The median age was 83 years (IQR 78-88) with a large majority of females (76.6%). The type of fracture varied with age in female subjects, with older women more frequently reporting pertrochanteric fractures. Therapeutic strategies for the different types of fracture depended on patients' age. During the study years, improvements in fracture classification and management strategies were observed, with a clear decreasing trend for non-operative solutions. In conclusion, the number of proximal femur fractures in older adults is growing, even if at a lower rate compared to population aging. The Italian surgical practice changed during the study period towards the implementation of the most recent guidelines.

Subspecialty Fellowship Training Is Not Associated With Better Outcomes in Fixation of Low-Energy Femoral Neck Fractures-An Analysis of the Fixation Using Alternative Implants for the Treatment of Hip Fractures Database

OBJECTIVES

To compare risk of reoperation for femoral neck fracture patients undergoing fixation with cancellous screws (CSs) or sliding hip screws based on surgeon fellowship (trauma-fellowship-trained vs. non-trauma-fellowship-trained).

DESIGN

Retrospective review of Fixation using Alternative Implants for the Treatment of Hip fractures data.

SETTING

Eighty-one centers across 8 countries.

PATIENTS/PARTICIPANTS

Eight hundred nineteen patients ≥50 years old with low-energy hip fractures requiring surgical fixation.

INTERVENTION

Patients were randomized to CS or sliding hip screw group in the initial dataset.

MAIN OUTCOME MEASUREMENTS

The primary outcome was risk of reoperation. Secondary outcomes included death, serious adverse events, radiographic healing, discharge disposition, and use of ambulatory devices postoperatively.

RESULTS

There was no difference in risk of reoperation between the 2 surgeon groups (P > 0.05). Patients treated by orthopaedic trauma surgeons were more likely to be overweight/obese and have major medical comorbidities (P < 0.05). There was a higher risk of serious adverse events, higher likelihood of radiographic healing, and higher odds of discharge to a facility for patients treated by trauma-fellowship-trained surgeons (P < 0.05).

CONCLUSIONS

Based on these data, risk of reoperation for low-energy femoral neck fracture fixation is equivalent regardless of fellowship training. The higher likelihood of radiographic healing noted in the trauma-trained group does not seem to have a major clinical implication because it did not affect risk of reoperation between the 2 groups. Patient-specific factors present preinjury, such as body habitus and medical comorbidities, may account for the lower odds of discharge to home and higher risk of postoperative medical complications for patients treated by orthopaedic trauma surgeons.

Conjoined tendon preserving posterior approach in hemiarthroplasty for femoral neck fractures: A prospective multicenter clinical study of 322 patients

PURPOSE

The posterior approach is widely used in femoral hemiarthroplasty. The major problem with this approach is the high risk of postoperative dislocation. A modified posterior approach, the conjoined tendon preserving posterior approach (CPP), was developed to reduce postoperative dislocations. The objective of this multicenter study was to evaluate the efficacy and safety of hemiarthroplasty performed using the CPP approach for femoral neck fractures.

METHODS

A total of 322 patients with femoral neck fracture, from 10 facilities, were prospectively studied. Bipolar hemiarthroplasty using the CPP approach was performed, using the same type of implants. Hip joint movement was not restricted following surgery, regardless of a patient's cognitive status. Final follow-up was performed 9.1 ± 1.5 months after surgery.

RESULTS

Hemiarthroplasty was undertaken in 320 patients using the CPP approach. The mean age, operative time, and intraoperative blood loss were 83.3 ± 7.4 years, 70.0 ± 22.7 min, and 134.8 ± 107.9 mL, respectively. No postoperative dislocations were observed during the study period. Intraoperative adverse events related to the hip joint included femoral fractures in five patients (1.6%) and trochanteric fractures in four patients (1.3%). Postoperative hip joint adverse events included a periprosthetic fracture in one patient (0.3%), deep infection in two patients (0.6%), and stem subsidence in one patient (0.3%). Postoperative deaths occurred in 23 patients (7.2%). One patient (0.3%) had a severe non-hip adverse event unrelated to surgery that prevented independent living, while five patients (1.6%) had a moderate non-hip adverse event that required treatment.

CONCLUSION

The CPP approach prevented postoperative dislocation following femoral hemiarthroplasty in elderly patients, with no CPP-associated specific adverse events.

Quality of fracture reduction is associated with patient survival at one year, but not 30 days, following trochanteric hip fracture fixation. A retrospective cohort study

INTRODUCTION

Few studies have been performed to evaluate the association between technical surgical factors and patient outcomes following hip fracture surgery. We performed a retrospective cohort study of elderly patients who had undergone fixation of trochanteric hip fractures using a sliding hip screw (SHS), with the aim of establishing whether there was a correlation between quality of fracture reduction and mortality at 30 days and one year.

PATIENTS AND METHODS

A retrospective cohort study was designed. Inclusion criteria were trochanteric (AO 31A1 or 31A2) fractures in patients aged ≥ 65 years, presenting <3 days after injury and fixed using an SHS. Fracture reduction was classified using the Baumgaertner Reduction Quality Criteria (BRQC). A validated predictor of mortality following hip fracture was used to stratify for confounding variables that might affect mortality. Multivariate logistic regression was used to explore the association between fracture reduction and mortality.

RESULTS

329 patients were identified (mean age 86, 27% male). 57% had a good reduction, 39% had a fair reduction and 4% had a poor reduction. As reduction grade deteriorated, predicted mortality increased (good reduction: 7.3%; fair reduction: 8.4%; poor reduction: 15.5%). Without adjustment for predicted mortality, there was a significant correlation between decreasing reduction grade and mortality at both time points (30-day: odds ratio 1.95, p = 0.049; one year: odds ratio 1.86, p = 0.003). When adjusted for predicted mortality, only one year mortality remained significant (30 day: odds ratio 1.61, p = 0.173; one year: odds ratio 1.62, p = 0.037).

CONCLUSION

Some, but not all, of the association between fracture reduction and mortality can be explained by predetermined predictors of a poor outcome. There remains, however, a correlation between poor fracture reduction and mortality at one year. Every effort must be made to achieve an anatomical reduction for these injuries, and trainees must be instructed in methods to achieve this.

The case for decreased surgeon-reported complications due to surgical volume and fellowship status in the treatment of geriatric hip fracture: An analysis of the ABOS database

Introduction

American orthopaedists are increasingly seeking fellowship sub-specialization. One proposed benefit of fellowship training is decrease in complications, however, few studies have investigated the rates of medical and surgical complications for hip fracture patients between orthopedists from different fellowship backgrounds. This study aims to investigate the effect of fellowship training and case volume on medical and surgical outcomes of patient following hip fracture surgical intervention.

Methods

1999–2016 American Board of Orthopedic Surgery (ABOS) Part II Examination Case List data were used to assess patients treated by trauma or adult reconstruction fellowship-trained orthopedists versus all-other orthopaedists. Rates of surgeon-reported medical and surgical adverse events were compared between the three surgeon cohorts. Using binary multivariate logistic regression to control of demographic factors, independent factors were evaluated for their effect on surgical complications.

Results

Data from 73,427 patients were assessed. An increasing number of hip fractures are being treated by trauma fellowship trained surgeons (9.43% in 1999–2004 to 60.92% in 2011–2016). In multivariate analysis, there was no significant difference in type of fellowship, however, surgeons with increased case volume saw significantly decreased odds of complications (16–30 cases: OR = 0.91; 95% CI: 0.85–0.97; p = 0.003; 31+ cases: OR = 0.68; 95% CI: 0.61–0.76; p<0.001). Femoral neck hip fractures were associated with increased odds of surgical complications.

Discussion

Despite minor differences in incidence of surgical complications between different fellowship trained orthopaedists, there is no major difference in overall risk of surgical complications for hip fracture patients based on fellowship status of early orthopaedic surgeons. However, case volume does significantly decrease the risk of surgical complications among these patients and may stand as a proxy for fellowship training. Fellows required to take hip fracture call as part of their training regardless of fellowship status exhibited decreased complication risk for hip fracture patients, thus highlighting the importance of additional training.

Association Between COVID-19 and Mortality in Hip Fracture Surgery in the National COVID Cohort Collaborative (N3C): A Retrospective Cohort Study

Background:

This study investigated the outcomes of coronavirus disease (COVID-19)-positive patients undergoing hip fracture surgery using a national database.

Methods:

This is a retrospective cohort study comparing hip fracture surgery outcomes between COVID-19 positive and negative matched cohorts from 46 sites in the United States. Patients aged 65 and older with hip fracture surgery between March 15 and December 31, 2020, were included. The main outcomes were 30-day all-cause mortality and all-cause mortality.

Results:

In this national study that included 3303 adults with hip fracture surgery, the 30-day mortality was 14.6% with COVID-19-positive versus 3.8% in COVID-19-negative, a notable difference. The all-cause mortality for hip fracture surgery was 27.0% in the COVID-19-positive group during the study period.

Dicussion:

We found higher incidence of all-cause mortality in patients with versus without diagnosis of COVID-19 after undergoing hip fracture surgery. The mortality in hip fracture surgery in this national analysis was lower than other local and regional reports. The medical community can use this information to guide the management of hip fracture patients with a diagnosis of COVID-19.

2021 John Charnley Award: A protocol-based strategy when using hemiarthroplasty or total hip arthroplasty for femoral neck fractures decreases mortality, length of stay, and complications

AIMS

While interdisciplinary protocols and expedited surgical treatment improve the management of hip fractures in the elderly, the impact of such interventions on patients specifically undergoing arthroplasty for a femoral neck fracture is not clear. We sought to evaluate the efficacy of an interdisciplinary protocol for the management of patients with a femoral neck fracture who are treated with an arthroplasty.

METHODS

In 2017, our institution introduced a standardized interdisciplinary hip fracture protocol. We retrospectively reviewed adult patients who underwent hemiarthroplasty (HA) or total hip arthroplasty (THA) for femoral neck fracture between July 2012 and March 2020, and compared patient characteristics and outcomes between those treated before and after the introduction of the protocol.

RESULTS

A total of 157 patients were treated before the introduction of the protocol (35 (22.3%) with a THA), and 114 patients were treated after its introduction (37 (32.5%) with a THA). The demographic details and medical comorbidities were similar in the two groups. Patients treated after the introduction of the protocol had a significantly reduced median time between admission and surgery (22.8 hours (interquartile range (IQR) 18.8 to 27.7) compared with 24.8 hours (IQR 18.4 to 43.3) (p = 0.042), and a trend towards a reduced mean time to surgery (24.1 hours (SD 10.7) compared with 46.5 hours (SD 165.0); p = 0.150), indicating reduction in outliers. Patients treated after the introduction of the protocol had a significantly decreased rate of major complications (4.4% vs 17.2%; p = 0.005), decreased median hospital length of stay in hospital (4.0 days vs 4.8 days; p = 0.008), increased rate of discharge home (26.3% vs 14.7%; p = 0.030), and decreased one-year mortality (14.7% vs 26.3%; p = 0.049). The 90-day readmission rate (18.2% vs 21.7%; p = 0.528) and 30-day mortality (3.7% vs 5.1%; p = 0.767) did not significantly differ. Patients who underwent HA were significantly older than those who underwent THA (82.1 years (SD 10.4) vs 71.1 years (SD 9.5); p < 0.001), more medically complex (mean Charlson Comorbidity Index 6.4 (SD 2.6) vs 4.1 (SD 2.2); p < 0.001), and more likely to develop delirium (8.5% vs 0%; p = 0.024).

CONCLUSION

The introduction of an interdisciplinary protocol for the management of elderly patients with a femoral neck fracture was associated with reduced time to surgery, length of stay, complications, and one-year mortality. Such interventions are critical in improving outcomes and reducing costs for an ageing population. Cite this article: Bone Joint J 2021;103-B(7 Supple B):3-8.

Comparative Analysis of Total Knee Arthroplasty Outcomes Between Arthroplasty and Nonarthroplasty Fellowship Trained Surgeons

Background

An adult reconstruction (AR) fellowship is designed to provide advanced training for a broad range of primary reconstructive and complex knee revision surgeries. This study aims to identify outcome differences between primary total knee arthroplasty (TKA) performed by AR fellowship-trained surgeons and non-AR (NAR) fellowship-trained surgeons.

Material and Methods

We retrospectively reviewed 7415 patients who underwent primary TKA from 2016 to 2020. Two cohorts were established based on whether the operation was performed by an AR or NAR fellowship-trained surgeon. Demographic, clinical data, and patient-reported outcome measures were collected at various time-points (preoperatively, 3 months, 1 year). Demographic differences were assessed with chi-square and independent sample t-tests. Primary outcomes were compared using multilinear regressions, controlling for demographic differences.

Results

AR surgeons performed 5194 (70%) cases while NAR surgeons performed 2221 (30%) cases. Surgical time (minutes) significantly differed between the 2 groups (101.26 vs 111.56; P < .001). Length of stay, 90-day all-cause readmissions, revisions, and all-cause emergency department visits did not statistically differ (P = .079, P = .978, P = .094, and P = .241, respectively). AR surgeons were more likely to discharge their patients home than NAR surgeons (P = .001). NAR group reported lower KOOS, JR scores at 3 months and 1 year (preop: 45.30 vs 45.79, P = .728; 3 months: 64.73 vs 59.47, P < .001; 1 year: 71.66 vs 69.56, P = .234); however, only 3-month scores statistically differed. Veterans RAND-12 Physical and Mental components scores (VR-12 PCS and MCS) were not statistically significant at any time-point between the cohorts. Delta-improvements preoperatively to 1 year in KOOS, JR (26.36 vs 23.77; P < .001) and VR-12 PCS (11.98 vs 10.62; P < .001) scores were significantly higher for the AR cohort but did not exceed the minimal clinically important difference.

Conclusion

This study demonstrates significantly shorter surgical times and greater improvements in KOOS, JR and VR-12 PCS scores associated with TKAs performed by AR fellowship-trained surgeons.

Who Did the Arthroplasty? Hip Fracture Surgery Reoperation Rates are Not Affected by Type of Training-An Analysis of the HEALTH Database

OBJECTIVES

This study compares outcomes for patients with displaced femoral neck fractures undergoing hemiarthroplasty (HA) or total hip arthroplasty (THA) by surgeons of different fellowship training.

DESIGN

Retrospective review of HEALTH trial data.

SETTING

Eighty clinical sites across 10 countries.

PATIENTS/PARTICIPANTS

One thousand four hundred forty-one patients ≥50 years with low-energy hip fractures requiring surgical intervention.

INTERVENTION

Patients were randomized to either HA or THA groups in the initial data set. Surgeons' fellowship training was ascertained retrospectively, and outcomes were compared.

MAIN OUTCOME MEASUREMENTS

The main outcome was an unplanned secondary procedure at 24 months. Secondary outcomes included death, serious adverse events, prosthetic joint infection (PJI), dislocation, discharge disposition, and use of ambulatory devices postoperatively.

RESULTS

There was a significantly higher risk of PJI in patients treated by surgeons without fellowship training in arthroplasty (P = 0.01), surgeons with unknown fellowship training (P = 0.03), and surgeons with no fellowship training (P = 0.02) than those treated by an arthroplasty-trained surgeon. There were significantly higher odds of being discharged to a facility rather than home in patients who underwent surgery by a surgeon with no fellowship training compared with arthroplasty-fellowship-trained surgeons (P = 0.03).

CONCLUSIONS

Arthroplasty for hip fracture can be performed by all orthopaedic surgeons with equivalent reoperation rates. Infection prevention strategies and use of "care pathways" by arthroplasty-fellowship-trained surgeons may account for the lower risk of PJI and higher rate of discharge to home. The authors advocate for the use of evidence-based infection prevention initiatives and standardized care pathways in this patient population.

The Impact of Arthroplasty Fellowship Training on Total Joint Arthroplasty: Comparison of Peri-Operative Metrics between Fellowship-Trained Surgeons and Non-Fellowship-Trained Surgeons

BACKGROUND

We sought to identify differences between total joint arthroplasties (TJAs) performed by adult reconstruction fellowship-trained surgeons (FT) than non-fellowship-trained surgeons (NFT).

METHODS

A single-institution database was utilized to identify patients who underwent elective TJA between 2016 and 2019.

RESULTS

In total, 16,882 TJAs were identified: 9111 total hip arthroplasties (THAs) and 7771 total knee arthroplasties (TKAs). Patients undergoing THA by FT surgeons were older (63.11 vs 61.84 years, P < .001), more likely to be white, insured by Medicare, and less likely to be active smokers (P < .0001). Both surgical time (90.03 vs 113.1 minutes, P < .0001) and mean length of stay (LOS) (1.85 vs 2.72 days, P < .0001) were significantly shorter for THAs performed by FT surgeons than NFT surgeons. A significantly greater percentage of patients were discharged home after THA by FT surgeons than NFT surgeons (88.7% vs 85.2%, P = .002). FT patients were quicker to mobilize with therapy and required 25% less opioids. TKAs performed by FT surgeons were associated with shorter surgical times (87.4 vs 94.92 minutes, P < .0001), LOS (2.62 vs 2.84 days, P < .0001), and nearly 19% less opioid requirement in the peri-operative period. In addition to higher Activity Measure for Post-Acute Care scores associated with FT surgeons after TKA, a significantly greater percentage of patients were discharged home after TKA by FT surgeons than NFT surgeons (83.97% vs 80.16%, P < .001).

CONCLUSION

For both THA and TKA, patients had significantly shorter surgical times, LOS, and required less opioids when their procedure was performed by FT surgeons compared to NTF surgeons. Patients who had their TJA performed by a FT surgeon achieved higher Activity Measure for Post-Acute Care scores and were discharged home more often than NFT surgeons. In an era of value-based care, more attention should be paid to the patient outcomes and financial implications associated with arthroplasty fellowship training.
