Nailing precision: a systematic review and meta-analysis of randomized controlled trials comparing piriformis and trochanteric entry points for femoral antegrade nailing.

INTRODUCTION: Entry point selection, a crucial aspect of femoral antegrade nailing, can impact nail fit and consequently fracture reduction. In adults, the standard entry portals used are the piriformis fossa and the tip of the greater trochanter. Previous systematic reviews comparing the two techniques have not been limited to Randomized Controlled Trials (RCTs) and have not consistently included the same available RCTs. MATERIALS AND METHODS: A systematic search of comparative studies regarding entry portal selection in femoral antegrade nailing was conducted on seven databases. Only Prospective RCTs comparing trochanteric and piriformis entry in the management of trochanteric or diaphyseal femur fractures were eligible for inclusion. RESULTS: Ultimately, only 6 RCTs were found eligible for inclusion. Five of the six included studies reported on operative time. The resulting mean difference (MD) illustrated a significant decrease in operative time by approximately 21.26 min (95% CI - 28.60 to - 13.92, p < 0.001) using trochanteric entry. Fluoroscopy exposure was reported on by four studies, however, only two studies were included in the analysis due to different reporting methods. Trochanteric entry used significantly less fluoroscopy than piriformis entry (MD -50.33 s, 95% CI - 84.441 to - 16.22, p = 0. 004). No significant difference in malalignment rates, delayed union rates, nonunion rates, pain scores, or complication rates was found. CONCLUSION: The significant differences found in operating time and fluoroscopy time align with those in other studies. While we were not able to pool the data on functional outcome scores, none of the included studies found a significant difference in scores by their last follow-up. Both approaches demonstrate comparable functional outcomes and safety profiles, indicating the choice of entry point should be at the discretion of the surgeon based on technique familiarity and fracture characteristics.

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.

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.

The impacts of anxiety and depression on outcomes in orthopaedic trauma surgery: a narrative review.

Introduction: The impact of anxiety and depression on outcomes in orthopaedic trauma surgery is a topic of growing research interest. Patients and methods: Orthopaedic trauma patients often experience high rates of psychiatric disorders, with anxiety and depression being the most prevalent. Mental health disorders have been shown to increase the risk of negative surgical outcomes and morbidity. This narrative review seeks to summarize the current literature surrounding the impacts of anxiety and depression on orthopaedic trauma surgery outcomes. Discussion: There is a bidirectional relationship between chronic pain and mental health disorders, involving overlapping brain regions and neurotransmitter pathways. Anxiety and depression have been identified as predictors of negative surgical outcomes in orthopaedic trauma patients. Screening tools like the Patient Health Questionnaire-9 (PHQ-9), Generalized Anxiety Disorder Screener-7 (GAD-7), and Medical Outcomes Study 36-item Short Form (SF-36) can assess mental health status and help tailor interventions. Psychological distress, chronic pain, and traumatic limb amputation are factors that contribute to adverse mental health outcomes in orthopaedic trauma patients. Opioid use for pain management is common in orthopaedic surgery, but it can worsen symptoms of depression and lead to dependency. Non-opioid pain management strategies may improve postoperative outcomes by reducing the impact of opioid-exacerbated depression. Conclusion: Mental health interventions, both preoperative and postoperative, are crucial in optimizing surgical outcomes and improving patient quality of life. Multidisciplinary approaches that address both physical and mental health are recommended for orthopaedic trauma patients. Further research is needed to develop effective interventions for improving mental health outcomes in this patient population.

The Use of Blocking Wires in Fibular Intramedullary Nailing of an Ankle Fracture with Hardware Failure: A Case Report.

A 24-year-old male, with a body mass index (BMI) of 31.7 and a previous open reduction and internal fixation (ORIF) of the left ankle seven years ago, presented to the emergency department with a peri-implant, comminuted fibula fracture with broken hardware and syndesmotic injury. The nature of the revision surgery made proper guidewire placement during fibular nailing difficult. Blocking wires assisted in ensuring proper guidewire placement. The patient was successfully managed with revision ORIF, fibular nailing, and syndesmotic fixation. Blocking wires are a helpful tool for achieving proper fracture alignment and stability during intramedullary nailing procedures and may be considered in fibular nailing situations.

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.

Influential literature regarding proximal junctional kyphosis: A bibliometric review.

Study design: Retrospective review. Objective: This bibliometric review summarizes the publication trends and critical information about the most cited Proximal Junction Kyphosis (PJK) articles. Background: Data: Proximal junctional kyphosis is frequently diagnosed after spinal fusion surgery. However, there continues to be heavy debate regarding the definition, incidence, risk factors, and treatment of this disorder. Methods: Nine hundred eleven articles were found when searching The Web of Science database with the keywords "Proximal junctional kyphosis" and "proximal junctional failure." The 200 top-cited articles were reviewed and screened to ensure PJK was discussed. The articles were filtered based on the highest to lowest number of citations, and the top 50 articles were chosen. Inclusion criteria included articles that contained a discussion of PJK and outcomes after surgery. Exclusion criteria included articles without mentioning PJK, or that studied non-human subjects. The 50 most cited articles were sorted by level of evidence and their classification for analysis. Results: The 50 most cited articles in this study were published a total of 6056 times. These articles were cited 71-413 times in the literature, with publications from 1994 to 2018. Most of the top 50 articles (64%) were published in the USA. Specifically, HSS and Washington University are the institutions with the most contributions to the publication of the most cited articles on PJK (n = 16). Lenke was the author that contributed to most publications in the top 50 articles on PJK. Conclusion: This study provides a framework for the most cited articles published on PJK. Most articles on this topic were in the category of clinical outcomes (36%) and were of a level of evidence III (46%). Most of the top-cited articles came from the journal Spine (68%) and were published in the USA (64%). These top-cited papers are essential to understanding this critical trending topic in spine surgery. Level of evidence: III.

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.

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.

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.

Defining tourniquetless total knee arthroplasty: A systematic review.

Introduction: Performing total knee arthroplasty (TKA) without the use of tourniquet is gaining popularity. However, performing a "tourniquetless TKA" has a variety of meanings regarding the timing and application of a tourniquet and associated techniques. The purpose of this systematic review was to evaluate the literature and more accurately define "tourniquetless TKA." Methods: A systematic review following PRISMA guidelines was performed of the PubMed, Web of Science, and Cochrane databases for articles published from 2016 to 2021. Inclusion criteria included papers that used "tourniquetless" or a similar term to describe their TKA procedure, original clinical studies, English language, and full-text studies. Results: A total of 1,096 studies were identified, of which 84 full text studies with 9,349 total patients were included. Overall, 17 (20.2%) of the studies performing tourniquetless TKA never applied a tourniquet, 17 (20.2%) applied a tourniquet but kept it deflated throughout the entire procedure, 2 (2.4%) applied a tourniquet and inflated during cementation only, and 48 (57.1%) did not specify. Ultimately, of the studies that did specify tourniquet use, only 17 studies (47.2%) truly never applied a tourniquet throughout the procedure. A review of 7 recommended techniques to control blood loss in tourniquetless TKA found that no one technique was performed in more than 10.6% of patients. Conclusion: Variation in the definition of tourniquetless TKA and the utilization of augmented techniques to control blood loss remains. We propose the terms "tourniquetless" for no tourniquet application, "tourniquet-available" for tourniquet applied but kept deflated throughout surgery, and "tourniquet-assisted" for tourniquet inflation during cementation only. These terms can help better differentiate the literature, guide surgeons as they transition to tourniquetless TKA, and assist in the development of more definitive protocols for tourniquetless TKA.

Characteristics and trends of the most cited papers in robotic assisted arthroplasty.

Purpose: To compile and analyze the top 50 most frequently cited articles published on robotic-assisted arthroplasty, allowing clinicians to effectively identify the most influential literature pertaining to this topic. Methods: Guidelines set by the Preferred Reporting Items for Systematic Reviews were used as the foundation for data collection and analysis. All papers pertaining to robotic-assisted arthroplasty were retrieved using the Scopus database. Data including: manuscript title, authors, total citation count, level of evidence, journal, publication year, and country of publication was extracted from a final list of articles. Results: The top 50 publications regarding robotic assisted arthroplasty were cited a total of 4530 times (including self-citations), with an average total of 91. The years with the most publications in the top 50 were: 2017, 2018, and 2019, producing 7, 6, and 5 papers, respectively. Only 4 papers in the top 50 were published prior to the year 2003. The most common level of evidence was level V, and the most common category was Clinical Outcomes (74%). The United States contributed half of the 50 articles, and Princess Grace Hospital and University of London were the most contributory institutions, each with 6 of the top 50 articles. Conclusion: This analysis provides a comprehensive review of the most cited and influential papers in robotic-assisted arthroplasty. Understanding these trends in the literature will ultimately pave the way for physicians and researchers to continue to innovate and research in a targeted manner as they gain an understanding of what has been studied and what remains inadequately explored. Level of evidence: 3.

Hip Arthroscopy Procedural Volume Is Low Among Graduating Orthopaedic Surgery Residents.

Purpose: The purpose of this study was to evaluate case volume and variability of hip arthroscopy exposure among graduating orthopaedic residents. Methods: The Accreditation Council for Graduate Medical Education (ACGME) surgical case log data from 2016 to 2020 for graduating United States orthopaedic surgery residents were assessed. Arthroscopy procedures of the pelvis/hip were identified. The average number of cases performed per resident was compared from 2016 to 2020 to determine the percent change in case volume. The 10th, 30th, 50th, and 90th percentiles of case volumes from 2016 to 2020 were presented to demonstrate case volume variability. Results: There was no change in the number of hip arthroscopy procedures between 2016 and 2020 [average: 8.4 ± 10 (range: 0 to 87) vs. 9.8 ± 12 (range: 0 to 101)] (P = .995). There was a wide variability in case volume among residents. The 90th percentile of residents performed 24 cases in 2020, compared to 2 cases in the 30th percentile and 0 cases amongst the 10th percentile of residents. Conclusions: Despite the growing popularity of hip arthroscopy, resident exposure to this highly technical procedure remains limited, with about one-third of residents performing 2 or less cases by graduation. Clinical Relevance: Understanding case volume and variability is important for orthopaedic surgery programs to ensure that graduating residents are gaining adequate exposure.
