Neonatal Compartment Syndrome Secondary to a Failed Peripheral Inserted Central Catheter Insertion: A Case Report.

Introduction: Neonatal compartment syndrome is a rare phenomenon with a limited number of cases reported in the literature with varying etiologies. Current literature categorizes etiologies as either intrinsic or extrinsic. To the best of our knowledge, difficult delivery and delivery through vacuum are the only two iatrogenic etiologies that have been reported in the literature. Thus, this may be the first reported case of neonatal compartment syndrome secondary to a failed peripherally inserted central catheter (PICC) insertion. Case Report: We present a case of a pre-mature neonate with diffuse discoloration, paralysis, and loss of palpable pulses of the right upper extremity after a failed PICC insertion. The clinical features led to a diagnosis of compartment syndrome. Interventions were not carried out due to the pre-maturity and instability of the patient. The patient passed away at 38 days of age due to refractory hypotension and patent ductus arteriosus. Conclusion: We present a case of neonatal compartment syndrome caused by a previously unreported etiology, highlighting the current dearth of knowledge. Clinicians should be aware of the unique clinical presentation of neonatal compartment syndrome and maintain high suspicion even without an obvious etiology.

Operative Treatment of a Patient with a Pathological Fracture through a Large Non-ossifying Fibroma: A Case Report.

Introduction: Non-ossifying fibroma (NOF) is a common benign fibrogenic bone lesion commonly found in the metaphysis of long bones. While small NOFs are typically asymptomatic and left untreated, large NOFs are often associated with pathologic fractures that can be treated conservatively or operatively. To our knowledge, the NOF presented in this case report is one of the largest reported in the literature. Case Report: We present a case of a 12-year-old Hispanic female who presented to our institution after falling off a horse and landing on her right leg and wrist. Radiographs revealed a right distal femur fracture through an unusually large lytic bone lesion. The patient was treated with curettage, grafting, open reduction, and internal fixation, given the unstable and pathological nature of the fracture. Conclusion: This case substantiates the literature that large fractures through a NOF can be appropriately managed operatively. However, orthopedic surgeons should be aware of the risks of surgery, including infection, when considering operative management of patients who present with large unstable pathologic fractures through a NOF.

Orthopedic surgeon-scientist representation is low among National Institutes of Health grants for rotator cuff research.

Background: The purpose of this study is to characterize National Institutes of Health (NIH) funding for rotator cuff research and evaluate the impact of orthopedic surgeons on this portfolio. Methods: The NIH's Research Portfolio Online Reporting Tools Expenditures and Results database was queried for "rotator cuff repair" or "rotator cuff tear" from the 2011 to 2021 fiscal years. Compound annual growth rates were calculated and grants were categorized by basic, clinical, or translational research. Funding totals were compared by Principal Investigator (PI) and grant characteristics. Results: A total of 52 grants were awarded to 38 PIs between 2011 and 2021, totaling $40,156,859. Annual NIH funding for rotator cuff tear and rotator cuff repair increased by a Compound annual growth rate of 11.0% from 2011 to 2021, compared to 3.4% for the total NIH budget. Orthopedic surgeon-scientists received $9,208,212 (22.9%), most commonly through R01 (80.5%) and K08 (7.1%) mechanisms. No significant difference in funding was found by PI sex (P = .332), degree (P = .460), academic rank (P = .118), or researcher type (P = .227). Professors had a higher h-index than associate and assistant professors (P = .001). Orthopedic surgeon-scientists had a higher h-index (mean 36.3 ± 9.4) compared to clinician-scientists (mean 8.0 ± 1.4) and research-scientists (35.5 ± 40.7) (P = .044). Clinical topics receiving the highest funding were rehabilitation (23.9%), diagnosis, (22.3%) and surgical technique (14.8%). Orthopedic surgeon-scientists acquired funding for diagnosis (57.1%), rehabilitation (17.0%), and surgical technique (14.5%). Discussion: While NIH funding for rotator cuff research is growing, orthopedic surgeon representation is low. Future studies should evaluate barriers to obtaining funding for orthopedic surgeon-scientists.

Miscoding in the Nationwide Inpatient Sample Database Raises Questions About Validity for Arthroplasty Research.

BACKGROUND: The use of administrative databases in arthroplasty research has increased over the past decade. The Nationwide Inpatient Sample (NIS) is one of the first and most frequently used. Despite many published articles using this dataset, there exists no standardization resource accounting for the potential of biased results. The purpose of our study was to assess the amount of discordant data between clinically relevant variables and propose a standard for using this database in primary total hip arthroplasty (THA) and total knee arthroplasty (TKA). METHODS: An initial set of patients undergoing total joint arthroplasty were identified from the NIS between 2016 and 2019 using the International Classification of Diseases, 10th Revision, Procedure Coding System. All records with THA and TKA in any of the procedure variables (PR1-PR20) were included. A total of 63 relevant and consistent variables were selected for individual comparison including diagnosis-related group (1), elective (1), procedure codes (20), day of main procedure (1), and diagnosis codes (40). Descriptive statistics were used. A total of 3,562,819 patients were included in the initial set. RESULTS: Using diagnosis-related groups, 5.3% were revision surgeries, 4.7% were not elective, 2.3% did not have THA or TKA as their primary procedure for hospitalization, and 2.9% of THA and 9.7% of TKA were bilateral. A total of 6.2% of the surgeries were done day(s) before or after admission, and 10.8% of THA and 6.3% of TKA were missing an orthopedic diagnosis for admission. Many had multiple orthopedic diagnoses for admission, 3.2% of THA and 0.7% of TKA. Overall miscoding was 23.3%. CONCLUSIONS: Using the NIS without standardized data processing to study elective, unilateral, primary THA and TKA introduces major bias. A logical and stepwise approach to curate the data before analysis is proposed to improve research quality when using this database in hip and knee arthroplasty studies.

Subtrochanteric nonunion after intramedullary nailing due to pathological fracture: proximal femoral replacement as a salvage approach.

PURPOSE: To assess proximal femoral replacement as a treatment solution for nonunion of pathologic subtrochanteric fractures after cephalomedullary nailing in patients with pathological fracture and previously irradiated bone. METHODS: Retrospective review of five patients with pathological subtrochanteric femoral fractures that were treated with cephalomedullary nailing and developed a nonunion, which was revised with conversion to a proximal endoprosthetic replacement. RESULTS: All five patients had previously been treated with radiation. One patient had the latest follow-up at 2 months postoperatively. At that time, the patient was walking with a walker for assistance, with no evidence of hardware failure or loosening on imaging. The remaining four patients had the latest follow-up ranging from 9 to 20 months after surgery. At their latest follow-up, three of the four patients were ambulatory with no pain, using only a cane for assistance with longer distances. The other patient demonstrated pain in his affected thigh, utilizing a walker for assistance with ambulation at latest follow-up, but not requiring further surgical interventions. There were no hardware failures or implant loosening through the follow-up period. None of the patients required revision, and there were no postoperative complications observed at their last follow-up. CONCLUSIONS: In patients with pathological fractures in the subtrochanteric region that is treated with cephalomedullary nailing and developed a nonunion, treatment with conversion to a proximal femoral replacement with a mega prosthesis is a valuable treatment with good functional results and low risk for complications. LEVEL OF EVIDENCE: Therapeutic level IV.

Varying Complication Rates and Increased Costs in Technology-Assisted Total Hip Arthroplasty Versus Conventional Instrumentation in 1,372,300 Primary Total Hips.

BACKGROUND: The use of technology allows surgeons increased precision in component positioning in total hip arthroplasty (THA). The objective of this study was to compare (1) perioperative complications and (2) resource utilizations between robotic-assisted (RA) and computer-navigated (CN) versus conventional instrumenttaion (CI) THA. METHODS: A retrospective cohort study was performed using a large national database to identify patients undergoing unilateral, primary elective THA from January 1, 2016 to December 31, 2019 using RA, CN, or CI. There were 1,372,300 total patients identified and included RA (29,735), CN (28,480), and CI (1,314,085) THA. Demographics, complications, lengths of stay, dispositions, and costs were compared between the cohorts. Binary logistic regression analyses were performed. RESULTS: The use of RA THA led to lower rates of intraoperative fracture (0.22% versus 0.39%), delirium (0.1% versus 0.2%), postoperative anemia (14.4% versus 16.7%), higher myocardial infarction (0.13% versus 0.08%), renal failure (1.7% versus 1.6%), blood transfusion (2.0% versus 1.9%), and wound dehiscence (0.02% versus 0.01%) compared to CI THA. The use of CN led to lower rates of respiratory complication (0.5% versus 0.8%), renal failure (1.1% versus 1.6%), blood transfusion (1.3% versus 1.9%), and pulmonary embolism (0.02% versus 0.1%) compared to CI THA. Total costs were increased in RA ($17,729 versus $15,977) and CN ($22,529 versus $15,977). Lengths of hospital stay were decreased in RA (1.8 versus 1.9 days) and CN (1.7 versus 1.9 days). CONCLUSIONS: Perioperative complication rates vary in technology-assisted THA, with higher rates in RA THA and lower rates in CN THA, relative to CI THA. Both RA THA and CN THA were associated with more costs, shorter postoperative hospital stays, and higher rates of discharge home compared to CI THA.

Lower Perioperative Complication Rates and Shorter Lengths of Hospital Stay Associated With Technology-Assisted Total Knee Arthroplasty Versus Conventional Instrumentation in Primary Total Knee Arthroplasty.

BACKGROUND: The use of technology allows increased precision in component positioning in total knee arthroplasty (TKA). The objectives of this study were to compare (1) perioperative complications and (2) resource utilization between robotic-assisted (RA) and computer-navigated (CN) versus conventional (CI) TKA. METHODS: A retrospective cohort study was performed using a national database to identify patients undergoing unilateral, primary elective TKA from January 2016 to December 2019. A total of 2,174,685 patients were identified and included RA (69,445), CN (112,225), or CI (1,993,015) TKA. Demographics, complications, lengths of stay, dispositions, and costs were compared between the cohorts. Binary logistic regression analysis was performed. RESULTS: The RA TKA cohort had lower rates of intraoperative fracture (0.05 versus 0.08%, P < .05), respiratory complications (0.6 versus 1.1%, P < .05), renal failure (1.3 versus 1.7%, P < .05), delirium (0.1 versus 0.2%, P < .05), gastrointestinal complications (0.04 versus 0.09%, P < .05), postoperative anemia (8.9 versus 13.9%, P < .05), blood transfusion (0.4 versus 0.9%, P < .05), pulmonary embolism, and deep vein thrombosis (0.1 versus 0.2%, P < .05), and mortality (0.01 versus 0.02%, P < .05) compared to conventional TKA, though the cohort did have higher rates of myocardial infarction (0.09 versus 0.07%, P < .05). The CN cohort had lower rates of myocardial infarction (0.02 versus 0.07%, P < .05), respiratory complications (0.8 versus 1.1%, P < .05), renal failure (1.5 versus 1.7%, P < .05), blood transfusion (0.8 versus 0.9%, P < .05), pulmonary embolism (0.08 versus 0.2%, P < .05), and deep vein thrombosis (0.2 versus 0.2%, P < .05) over CI TKA. Total cost was increased in RA (16,190 versus $15,133, P < .05) and CN (17,448 versus $15,133, P < .05). However, the length of hospital stay was decreased in both RA (1.8 versus 2.2 days, P < .05) and CN (2.1 versus 2.2 days, P < .05). CONCLUSIONS: Technology-assisted TKA was associated with lower perioperative complication rates and faster recovery.

Safe Zones and Trajectory of Femoral Pin Placement in Robotic Total Knee Arthroplasty.

Background: Robotic-assisted total knee arthroplasty may result in array pin-related complications. Lack of knowledge on ideal pin placement results in varied insertion sites and trajectory, with unknown risks to surrounding neurovascular structures. Methods: This study included 10 lower-extremity magnetic resonance images. Images were subdivided into 6 zones of study. Zones consisted of a correlating axial image with femoral pin placement replicated by drawing a line angled 45° from the anterior to posterior reference in the anteromedial to posterolateral femoral quadrants. The distances from the pin paths to the neurovascular structures were measured. Results: Zone 2C demonstrated femoral pin trajectory an average of 14 mm from the femoral artery/vein. In Zone 2B, proximity increased to an average of 30 mm to the femoral artery and 29 mm to the femoral vein. At Zone 1A, the popliteal artery and vein were on average 22 mm from the femoral pin, while the common peroneal nerve was an average of 21 mm. Placing pins in Zone 1A poses a high risk of injury to the genicular arteries. Women demonstrated greater proximity to neurovascular structures than men in 66% of the sites (P < .05). Conclusions: This classification system for safe zones and trajectory of femoral pin placement in robotic-assisted total knee arthroplasty demonstrates that proximally, the profunda femoris and femoral artery/vein are at risk of injury, while distally, the genicular arteries, common peroneal nerve, and popliteal artery/vein are at risk. Caution should be exercised if femoral pins are inserted with an angle less than 45°, especially in women.

Subacromial balloon spacers for the treatment of irreparable rotator cuff tears: a review.

Massive irreparable rotator cuff tears (RCTs) are a commonly encountered orthopedic condition that can be difficult to treat. Several techniques have been described to manage these tears, with the implantable subacromial balloon spacer being one of the most recent. The device, which has only been approved for clinical use in the United States since 2021, functions by resisting the superior humeral head migration seen in the setting of massive RCTs and restoring normal shoulder biomechanics, as corroborated by cadaveric studies. However, results regarding clinical outcomes have been mixed to date, and further high-quality studies are needed to define the optimal use of the subacromial balloon spacer in the treatment of massive irreparable RCTs.

The Rate of Medial Ulnar Collateral Ligament Repair Is Increasing While Reconstruction Remains the Most Common Procedure Overall Among Early-Career Orthopaedic Surgeons.

Purpose: To determine the practice patterns and complication rates in medial ulnar collateral ligament (MUCL) repair versus reconstruction procedures performed by early-career orthopaedic surgeons each year between 2010 and 2020, stratified by fellowship training and concomitant procedures performed, during their 6-month American Board of Orthopaedic Surgery (ABOS) Case List collection period. Methods: The ABOS database was queried for MUCL reconstruction and MUCL repair procedures reported by ABOS Part II Oral Examination examinees from 2010 to 2020. Surgeon fellowship training background, patient demographics, procedural diagnosis codes, complications, and concomitant procedures were recorded for each case. Differences between overall procedure rates and the associated complications reported were examined. Data regarding the specific injury pathology and other patient-specific characteristics for each case were not available. Results: In total, 187 primary procedures performed to address isolated MUCL injuries were reported. Of those, 83% (n = 155) were reconstructions and 17% (n = 32) were repairs. The annual percentage of MUCL repair increased from 10% (1/10) in 2010 to 38% (8/21) in 2020 (linear regression; R2 = 0.56, P < .05). The cumulative complication rate for MUCL reconstruction (11.6%) was significantly lower than for MUCL repair (25%) from 2010 to 2020 (P < .05). This remained true among subsets of cases from Orthopaedic Sports Medicine, Shoulder & Elbow, and or Hand Surgery fellowship-trained examinees, although only statistically significant in the Hand Surgery subset. Reported complication rates were not significantly different among cases in which concurrent ulnar nerve neuroplasty and/or transposition or concurrent elbow arthroscopy were performed. Conclusions: Among cases reported by ABOS Part II Oral Examination examinees from 2010 to 2020, there was an increasing rate of MUCL repair whereas MUCL reconstruction remained more common overall. Interestingly, the overall complication rates were significantly lower for MUCL reconstruction than for MUCL repair both in isolation and when concurrent procedures were performed. Level of Evidence: Level III, retrospective cohort study.

Orthopedic approaches for bone sarcoma: A bibliometric review of the 50 most cited papers.

Background: Curative treatment of bone sarcoma is primarily based on operative management. The Orthopedic Oncology approach towards this disease has evolved greatly to the breakthrough in systemic treatment options as well as unique implant designs favoring limb salvage over amputations. The purpose of this study was to perform a bibliometric analysis of the top 50 most cited papers related to the orthopedic the approach to bone sarcomas. Methods: We queried the ISI Web of Knowledge database in July 2022. Keywords utilized were: ""Bone Sarcoma" OR "Osteosarcoma" OR "Ewing Sarcoma" OR "Chondrosarcoma" OR "Chordoma". The top 50 articles pertaining to the orthopedic approach to bone sarcoma were included for analysis and included manuscript title, authors, citation count, journal and publication year. Results: The mean number of citations are 187.06 (Range 125-400; SD 67.83). The average citations per year is 10.03 (Range 47.86-3.43; SD 8.05). Many articles were published from 2000 to 2009 (n = 20) and 1990-1999 (n = 13). The majority of the articles were published by institutions within the United States (n = 32). The most common level of evidence was level IV (n = 37). Majority of the articles focused on treatment outcome (n = 22). Conclusion: This study offers a comprehensive review of the most cited literature regarding orthopedic approaches to bony sarcomas. Modern treatment approaches for bone sarcoma has resulted in an increased focus within the literature on achieving disease free survival wide tissue margins. Understanding the trends of available studies allows for physicians and researchers to target and innovate future areas of study.

The Relative Citation Ratio: Evaluating a New Measure of Scientific Influence Among Academic Sports Medicine Surgeons.

Background: Objective measures of research influence are being increasingly utilized to evaluate and compare academic faculty. However, traditional bibliometrics, such as the Hirsch index and article citation count, are biased by time-dependent factors and are limited by a lack of field normalization. The relative citation ratio (RCR) is a new field- and time-normalized article-level metric developed by the National Institutes of Health (NIH). Purpose/Hypothesis: The purpose of this study was to evaluate the RCR among fellowship-trained academic sports medicine surgeons and to analyze physician factors associated with RCR values. We hypothesized that the mean RCR score for fellowship-trained academic sports medicine surgery faculty will fall above the NIH standard. Study Design: Cross-sectional study. Methods: A retrospective data analysis was performed using the iCite database for all fellowship-trained sports medicine surgery faculty associated with Accreditation Council for Graduate Medical Education-accredited orthopaedic surgery residency programs in December 2021. In eligible faculty, the mean RCR, weighted RCR, and total publication count were compared by sex, career duration, academic rank, and presence of additional degrees. A mean RCR value of 1.0 is the NIH-funded field-normalized standard. The data herein are presented as the median and interquartile range, in addition to the mean and standard deviation, to account for outliers of the mean and weighted RCR scores. Results: A total of 624 fellowship-trained sports medicine surgery faculty members from 160 orthopaedic surgery residency programs were included in the analysis. Overall, faculty produced impactful research, with a median RCR of 1.6 (interquartile range, 1.0-2.2) and a median weighted RCR of 19.3 (interquartile range, 5.1-69.3). Advanced academic rank and career longevity were associated with increased weighted RCR and total publication count. All subgroups analyzed had an RCR value >1.0. Conclusion: Study findings indicate that fellowship-trained academic sports medicine surgery faculty are highly productive and produce impactful research, as evidenced by the high median RCR value relative to the benchmark NIH RCR value of 1.0.

Analysis of Questions in Sections of the Orthopaedic In-Training Examination: A Scoping Review.

PURPOSE: The purpose of this review was to assess all available studies that analyzed the types of questions in individual sections of the Orthopaedic In-Training Examination, which may be used as a reference for residents studying for their examination. METHODS: Following the Providing Innovative Service Models and Assessment extension for Scoping Reviews guidelines, a systematic review was conducted on studies that report on sections or question categories of the Orthopaedic In-Training Examination using PubMed, MEDLINE, and Web of Science databases. Two reviewers and an arbitrator reviewed and extracted relevant data from 20 included studies which made up the systematic review. RESULTS: All 20 studies in the review reported the mean number of questions per section, with the highest coming from musculoskeletal trauma (18.9% to 19.0%). 18 studies reported the Buckwalter taxonomic classification; 42.0% of questions were T1, 18.2% were T2, and 39.5% were T3 with a wide range from section to section. Primary sources were nearly three times more likely to be cited when compared with textbook sources. There were 12 journals that were commonly cited with the most being the Journal of Bone and Joint Surgery: American Volume (17/18). DISCUSSION: This study accurately portrays the characteristics of each section of the Orthopaedic In-Training Examination over the past 10 years. These data suggest that orthopaedic residents may be inclined to focus on musculoskeletal trauma, topics related to clinical management, and primary journal sources for studying. In addition, residency programs may choose to focus on higher yield sources or material to prepare their residents for the examination.

The efficacy of patient specific instrumentation (PSI) in total hip arthroplasty (THA): A systematic review and meta-analysis.

Background: Patient-specific instrumentation (PSI) has been suggested to reduce improper component positioning, though the effectiveness of PSI in total hip arthroplasty (THA) remains inconclusive. The purpose of this study was to evaluate the radiographic parameters and clinical outcomes comparing PSI and standard instrumentation (SI). Methods: This systematic review and meta-analysis was conducted in accordance with the 2020 PRISMA statement and was registered on PROSPERO. PubMed, Embase, Scopus, Google Scholar, and ClinicalTrials.gov were searched for relevant studies pertaining to the use of PSI in THA. Inclusion criteria included PSI used in THA, PSI was directly compared to SI, and publication in English. Exclusion criteria included non-primary THA, review articles, abstracts, book chapters, and animal models. Results: 2,458 studies were initially identified, with 13 studies (677 THAs: 338 controls, 339 PSI) meeting all criteria. PSI was favored for the deviation from the preoperative plan for acetabular cup position for anteversion (p = 0.04) and inclination (p = 0.0002); risk of acetabular cup positioning outside the Lewinnek safe zone for anteversion (p = 0.005) and inclination (p < 0.0001); and postoperative Harris Hip Score (p = 0.0002). No significant differences were found for the deviation from the preoperative plan for femoral stem position for anteversion (p = 0.74) or varus/valgus (p = 0.15); intraoperative time (p = 0.55); or intraoperative blood loss (p = 0.62). Conclusion: The use of PSI in THA is effective in improving acetabular component positioning and postoperative functional outcomes, without increasing intraoperative time or blood loss, compared to SI.

Level of Evidence: 3.

Calcium pyrophosphate dihydrate crystals in a 9-year-old with osteomyelitis of the knee: A case report.

BACKGROUND: Calcium pyrophosphate dihydrate deposition disease (CPPD), or pseudogout, is an inflammatory arthritis common among elderly patients, but rarely seen in patients under the age of 40. In the rare cases presented of young patients with CPPD, genetic predisposition or related metabolic conditions were almost always identified. CASE SUMMARY: The authors report the case of a 9-year-old boy with no past medical history who presented with acute knee pain and swelling after a cat scratch injury 5 d prior. Synovial fluid analysis identified calcium pyrophosphate dihydrate crystals. Further MRI analysis identified osteomyelitis and a small soft tissue abscess. CONCLUSION: This case presents the extremely rare diagnostic finding of calcium pyrophosphate dihydrate crystals in a previously healthy pediatric patient. The presence of osteomyelitis presents a unique insight into the pathogenesis of these crystals in pediatric patients. More research needs to be done on the role of CPPD in pediatric arthritis and joint infection.

Sinus tarsi approach in high-risk patients with displaced intra-articular calcaneus fractures: A case series.

Purpose: Though research exists regarding calcaneal fractures, the treatment approach for displaced intra-articular calcaneal fractures (DIACF) remains controversial. The most common approach, the extensile lateral approach (ELA), for the treatment of DIACFs has high rates of wound complications reported. In contrast, the sinus tarsi approach (STA) is becoming more popular due to its minimally invasive technique. The objective of this retrospective study is to investigate the incidence of wound complications in high-risk patients with DIACF following operative fixation via the STA. Methods: Following IRB approval, a retrospective chart review was performed between 2007 and 2013 to assess high-risk patients for the presence of wound complications, including deep infections and delayed wound healing, following the use of STA for the management of DIACF's (n = 36). Demographics, risk factors, and secondary outcomes such as time to surgery were recorded. Results: Of the 36 high-risk patients included in our study, seven had post-operative complications following operative fixation via the STA. Specifically, four patients had delayed wound healing, and three developed deep infections. Time to surgery had the greatest negative effect on postoperative complications and was influenced by age, sex, and the presence of a concomitant injury. Conclusion: In conclusion, this study demonstrates that the STA is a viable option for high-risk patients with displaced intra-articular fractures. Additionally, time to surgery should be minimized, when possible, to reduce risks of post-operative complications, including infections and delayed wound healing.

The Most Influential Publications in Outpatient Total Joint Arthroplasty.

Background: Total joint replacements are some of the most common procedures performed by surgeons. There has been a recent increase to transition these procedures to the outpatient setting. Objective: Our study seeks to identify the most influential publications, in terms of total citations, regarding outpatient total hip and knee replacement surgeries. Methods: The database used to collect the data for this analysis was Clarivate Analytics Web of Science. The search query selected and used to collect data was: "outpatient or ambulatory," with a "Title" filter AND "total joint replacement" AND "total joint arthroplast*" with "Topic" filters. The papers returned were then sorted by total number of citations and exported to Google Sheets for further analysis. Results: The most cited publication was "Outpatient total knee arthroplasty with a minimally invasive technique," by Berger et al.. This was the oldest publication analyzed (2005), the most recent publication being published in 2020. The publications analyzed were cited a total number of 1,774 times and averaged 35.5 citations per year. The Journal with the most attributable publications was The Journal of Arthroplasty. Conclusion: This study provides a measure of the most cited articles on outpatient arthroplasty. Most literature on the topic were categorized as Clinical Science and Outcomes (50%), comprised level of evidence III (28%), were published in the Journal of Arthroplasty (54%) and came out of the United States (76%). Knowledge of these most influential articles allows for a foundation of understanding on a rapidly growing area of arthroplasty among clinicians.
