Racial and Ethnic Disparities in Sports Medicine and the Importance of Diversity.

Within orthopedics surgery as a specialty, sports medicine is one of the least diverse surgical subspecialties. Differences in minority representation between patient and provider populations are thought to contribute to disparities in care, access, and outcomes.

The Majority of Black Orthopaedic Surgeons Report Experiencing Racial Microaggressions During Their Residency Training.

BACKGROUND: Orthopaedic surgery is the least-diverse surgical specialty based on race and ethnicity. To our knowledge, the impact of this lack of diversity on discriminatory or noninclusive experiences perceived by Black orthopaedic surgeons during their residency training has never been evaluated. Racial microaggressions were first defined in the 1970s as "subtle verbal, behavioral, and environmental indignities, whether intentional or unintentional, that communicate hostile, derogatory, or negative racial slights and insults to the target person or group." Although the term "microaggression" has long been established, more recently, as more workplaces aim to improve diversity, equity, and inclusion, it has entered the medical profession's lexicon as a means of describing the spectrum of racial discrimination, bias, and exclusion in the healthcare environment. QUESTION/PURPOSES: (1) What is the extent of discrimination that is perceived by Black orthopaedic surgeons during residency? (2) What subtypes of racial microaggressions (which encompasses racial discrimination, bias, and exclusion) do Black orthopaedic surgeons experience during residency training, and who are the most common initiators of these microaggressions? (3) What feedback statements could be perceived as racially biased to Black orthopaedic surgeons in residency training? (4) Are there gender differences in the reported types of racial microaggressions recalled by Black respondents during residency training? METHODS: An anonymous survey was administered between July 1, 2020, and September 1, 2020, to practicing orthopaedic surgeons, residents, and fellows in the J. Robert Gladden Orthopaedic Society database who self-identify as Black. There were 455 Black orthopaedic surgeons in practice and 140 Black orthopaedic residents or fellows in the database who met these criteria. Fifty-two percent (310 of 595) of participants responded. Fifty-three percent (243 of 455) were practicing surgeons and 48% (67 of 140) were current residents or fellows. Respondents reported their perception of discrimination in the residency workplace using a modified version of the single-item Perceived Occupational Discrimination Scale and were asked to recall any specific examples of experiences with racial discrimination, bias, or exclusion during their training. Examples were later categorized as different subtypes of racial microaggressions and were quantified through a descriptive analysis and compared by gender. RESULTS: Among survey respondents, 34% (106 of 310) perceived a lot of residency workplace discrimination, 44% (137 of 310) perceived some residency workplace discrimination, 18% (55 of 310) perceived a little residency workplace discrimination, and 4% (12 of 310) perceived no residency workplace discrimination. Categorized examples of racial microaggressions experienced in residency were commonly reported, including being confused for a nonphysician medical staff (nurse or physician's assistant) by 87% (271 of 310) of respondents or nonmedical staff (janitorial or dietary services) by 81% (250 of 310) of respondents. Racially explicit statements received during residency training were reported by 61% (190 of 310) of respondents. Thirty-eight percent (117 of 310) of such statements were reportedly made by patients and 18% (55 of 310) were reportedly made by attending faculty. Fifty percent (155 of 310) of respondents reported receiving at least one of nine potentially exclusionary or devaluing feedback statements during their residency training. Among those respondents, 87% (135 of 155) perceived at least one of the statements to be racially biased in its context. The three feedback statements that, when received, were most frequently perceived as racially biased in their context was that the respondent "matched at their program to fulfill a diversity quota" (94% [34 of 36]), the respondent was unfriendly compared with their peers (92% [24 of 26]), or that the respondent was "intimidating or makes those around him/her uncomfortable" (88% [51 of 58]). When compared by gender, Black women more frequently reported being mistaken for janitors and dietary services at 97% (63 of 65), compared with Black men at 77% (187 of 244; p < 0.01). In addition, Black women more frequently reported being mistaken as nurses or physician assistants (100% [65 of 65]) than Black men did (84% [205 of 244]) during orthopaedic residency training (p < 0.01). Black women also more frequently reported receiving potentially devaluing or exclusionary feedback statements during residency training. CONCLUSION: Perception of workplace discrimination during orthopaedic residency training is high (96%) among Black orthopaedic surgeons in the United States. Most respondents reported experiencing discrimination, bias, and exclusion that could be categorized as specific subtypes of racial microaggressions. Several different examples of racial microaggressions were more commonly reported by Black women. Certain feedback statements were frequently perceived as racially biased by recipients. CLINICAL RELEVANCE: To better understand barriers to the successful recruitment and retention of Black physicians in orthopaedics, the extent of racial discrimination, bias, and exclusion in residency training must be quantified. This study demonstrates that racial discrimination, bias, and exclusion during residency, wholly categorized as racial microaggressions, are frequently recalled by Black orthopaedic surgeons. A better understanding of the context of these experiences of Black trainees is a necessary starting point for the development of a more inclusive workplace training environment in orthopaedic surgery.

Comparison of a Novel Anatomic Technique and the Docking Technique for Medial Ulnar Collateral Ligament Reconstruction.

BACKGROUND: Current reconstruction techniques do not re-create the distal ulnar collateral ligament (UCL) insertion. Reconstructing the distal extension of the anterior band ulnar footprint may increase elbow stability and resistance against valgus stress after UCL reconstruction (UCLR). PURPOSE/HYPOTHESIS: The purpose was to test a new technique for UCLR, a modification of the docking technique, aimed at re-creating the distal ulnar footprint anatomy of the anterior band. We hypothesize that this novel "anatomic" technique will provide greater resistance to valgus stress after UCLR when compared with the docking technique. STUDY DESIGN: Descriptive laboratory study. METHODS: Eighteen unpaired cadaveric arms were dissected to capsuloligamentous elbow structures and potted. With use of a servohydraulic load frame, 5 Ncm of valgus stress was placed on the UCL-intact elbows at 30°, 60°, 90°, and 120° of flexion. UCLR was performed on each elbow, randomized to either the docking technique or the anatomic technique. After UCLR, the elbow was again tested at 30°, 60°, 90°, and 120° of flexion. Ulnohumeral joint gapping was calculated using a 3-dimensional motion capture system applied to markers attached to the ulna and humerus. Differences in gapping among the intact state and docking and anatomic techniques were compared using a 2-way analysis of variance with significance set to P < .05. RESULTS: There was no significant difference in gapping between the anatomic and docking technique groups regardless of elbow flexion angle. All reconstructed groups showed increased gapping relative to intact, but all increases were below the clinically relevant level of 1 mm. CONCLUSION: Ulnohumeral joint gapping and resistance to valgus stress were similar between the anatomic technique and the docking technique for UCLR. CLINICAL RELEVANCE: This study provides evidence that the anatomic technique is a viable alternative UCLR method as compared with the docking technique in a cadaveric model.

Perception of Racial and Intersectional Discrimination in the Workplace Is High Among Black Orthopaedic Surgeons: Results of a Survey of 274 Black Orthopaedic Surgeons in Practice.

INTRODUCTION: There are approximately 573 practicing Black orthopaedic surgeons in the United States, which represents 1.9% overall. The purpose of this study was to describe this underrepresented cohort within the field of orthopaedic surgery and to report their perception of occupational opportunity and workplace discrimination. METHODS: An anonymous survey was administered to 455 practicing orthopaedic surgeons who self-identify as Black. The 38-question electronic survey requested demographic and practice information and solicited perspectives on race and racial discrimination in current orthopaedic practices and general views regarding occupational opportunity and discrimination. RESULTS: The survey was completed by 274 Black orthopaedic surgeons (60%). Over 97% of respondents believe that Black orthopaedic surgeons in the United States face workplace discrimination. Most Black orthopaedic surgeons (94%) agreed that racial discrimination in the workplace is a problem but less than 20% agreed that the leaders of national orthopaedic organizations are trying sincerely to end it. Black female orthopaedic surgeons reported lower occupational opportunity and higher discrimination than Black male orthopaedic surgeons across all survey items. DISCUSSION: This study is the first to report on the workplace environment and the extent of discrimination experienced by Black surgeons, specifically Black orthopaedic surgeons in the United States. Most respondents, particularly female respondents, agreed that racial discrimination and diminished occupational opportunity are pervasive in the workplace and reported experiencing various racial microaggressions in practice.

Age and Racial Disparities in Telemedicine Utilization in an Academic Orthopedic Surgery Department.

Introduction: The COVID-19 pandemic has highlighted significant racial and age-related health disparities. In response to pandemic-related restrictions, orthopedic surgery departments have expanded telemedicine use. We analyzed data from a tertiary care institute during the pandemic to understand potential racial and age-based disparities in access to care and telemedicine utilization. Materials and Methods: Data on patient race and age, and numbers of telemedicine visits, in-person office visits, and types of telemedicine were extracted for time periods during and preceding the pandemic. We calculated odds ratios for visit occurrence and type across race and age groups. Results: Patients ages 27-54 were 1.3 (95% confidence interval [CI] 1.1-1.4, p < 0.01) and 1.2 (95% CI 1.0-1.3, p < 0.05) times more likely to be seen than patients <27 during the pandemic, versus the 2019 and 2020 controls. Patients 54-82 were 1.3 (95% CI 1.1-1.5, p < 0.001) times more likely to be seen than patients <27 during the pandemic versus the 2019 control. Patients 27-54, 54-82, and 82+, respectively, were 3.3 (95% CI 2.6-4.2, p < 1e-20), 3.5 (95% CI 2.8-4.4, p < 1e-24), and 1.9 (95% CI 1.1-3.4, p < 0.05) times more likely to be seen by telemedicine than patients <27. Among pandemic telemedicine appointments, Black patients were 1.5 (95% CI 1.2-1.9, p < 1e-3) times more likely to be seen by audio-only telemedicine than White patients, as compared with video telemedicine. Conclusions: Telemedicine access barriers must be reduced to ensure that disparities during the pandemic do not persist.

Why and Where to Move the Tibial Tubercle: Indications and Techniques for Tibial Tubercle Osteotomy.

Patellofemoral disorders including pain and instability are common orthopedic problems, particularly in the adolescent population. Patellofemoral pain is usually anterior, poorly localized, and diffuse. Because of its multifactorial etiology, patellofemoral pain can be clinically challenging to diagnose and manage. With regards to instability, predisposing factors include trochlear dysplasia, patella alta, patellar tilt, and an elevated tibial tuberosity and trochlea groove distance. Initially, nonoperative management is recommended to treat patellofemoral maladies such as overload, maltracking, and acute first-time dislocations. However, tibial tubercle transfer (TTT) is commonly used to address cases of symptomatic malalignment and overload and recurrent patellar instability. The tubercle can be translated in multiplanar directions to correct patellar height, maltracking associated with instability, and to offload chondral defects. A thorough understanding of the anatomy and biomechanics of the patellofemoral joint is essential for optimizing results after TTT. Individualizing the direction and degree of tubercle transfer on the basis of patient parameters is critical to producing successful long-term results after surgery. This article will review the indications for performing a TTT and highlight the various techniques.

Influence of tibial rotation on tibial tunnel position measurements using lateral fluoroscopy in anterior cruciate ligament reconstruction.

PURPOSE: The purpose of the current study was to evaluate the influence of internal and external knee rotation on tibial tunnel position measurements in anterior cruciate ligament reconstruction using the Amis and Jakob line. METHODS: Anatomic double bundle ACL reconstruction was performed in seven cadaveric knees. Afterwards, the knees were CT scanned, and 3D CT models were established. Utilizing these models, strict lateral and radiographs with the knees in 5°, 10°, and 20° of internal as well as external rotation were established. Using these radiographs, the positions of the anteromedial (AM) and posterolateral (PL) tibial tunnels were measured using the Amis and Jacob line. The tunnel positions of the strict lateral were compared to the rotated radiographs. To assess the inter- and intraobserver reliability, two independent observers measured the tunnel positions, and one observer measured twice. RESULTS: Significant differences for the AM tunnel position were observed if more than 10° of external or 20° of internal rotation were applied. For the PL tunnel position, no significant differences were found between the strict lateral and the rotated radiographs. Inter- and intraobserver reliability was good. CONCLUSIONS: The accuracy of the Amis and Jakob line is dependent on the degree of knee rotation and the position of the measured tunnel. Therefore, when using the Amis and Jakob line to determine the tibial tunnel position during surgery, attention should be paid to rotational alignment of lateral radiographs. However, the maximum rotation tested in the present study (20°) showed only a difference in tunnel position of 3.3 % compared to optimal rotational alignment. Thus, in most cases, the effects of minor malrotation on tunnel position measurement should be of minimal clinical significance.

HGF mediates the anti-inflammatory effects of PRP on injured tendons.

Platelet-rich plasma (PRP) containing hepatocyte growth factor (HGF) and other growth factors are widely used in orthopaedic/sports medicine to repair injured tendons. While PRP treatment is reported to decrease pain in patients with tendon injury, the mechanism of this effect is not clear. Tendon pain is often associated with tendon inflammation, and HGF is known to protect tissues from inflammatory damages. Therefore, we hypothesized that HGF in PRP causes the anti-inflammatory effects. To test this hypothesis, we performed in vitro experiments on rabbit tendon cells and in vivo experiments on a mouse Achilles tendon injury model. We found that addition of PRP or HGF decreased gene expression of COX-1, COX-2, and mPGES-1, induced by the treatment of tendon cells in vitro with IL-1ß. Further, the treatment of tendon cell cultures with HGF antibodies reduced the suppressive effects of PRP or HGF on IL-1ß-induced COX-1, COX-2, and mPGES-1 gene expressions. Treatment with PRP or HGF almost completely blocked the cellular production of PGE2 and the expression of COX proteins. Finally, injection of PRP or HGF into wounded mouse Achilles tendons in vivo decreased PGE2 production in the tendinous tissues. Injection of platelet-poor plasma (PPP) however, did not reduce PGE2 levels in the wounded tendons, but the injection of HGF antibody inhibited the effects of PRP and HGF. Further, injection of PRP or HGF also decreased COX-1 and COX-2 proteins. These results indicate that PRP exerts anti-inflammatory effects on injured tendons through HGF. This study provides basic scientific evidence to support the use of PRP to treat injured tendons because PRP can reduce inflammation and thereby reduce the associated pain caused by high levels of PGE2.

Improved nondominant hand performance on a laparoscopic virtual reality simulator after playing the Nintendo Wii.

BACKGROUND: Video games have been shown to improve eye-hand coordination, spatial visualization, manual dexterity, and rapid mental processing, which are important in the acquisition of laparoscopic skills. This study investigated the relationship between playing Nintendo(®) Wii™ and virtual reality (VR) laparoscopic surgery simulator performance. We hypothesized that playing the Wii would improve surgical skills performance on a VR laparoscopic simulator and hoped to elucidate which tasks, in particular, would be most beneficial for nondominant hand training. METHODS: This was a single-blinded, randomized, prospective study conducted with 23 student volunteers. VR laparoscopic skills were assessed at baseline on a Simbionix LapMentor™ Surgical Simulator (Simbionix Ltd., Israel) and after the gaming period of 2 weeks. Simulator performance metrics were compared between groups using nonparametric statistics and an alpha of 0.05. RESULTS: Compared with the control group, the Wii-playing group demonstrated greater improvement of six measures, including accuracy on the eye-hand coordination task (p = 0.04), faster completion time (p = 0.04), decreased number of left-handed movements (p = 0.03), decreased left handed total path length (p = 0.03), decreased total number of grasping attempts (p = 0.04), and improved left-handed economy of movement (p = 0.05) for the bimanual clipping and grasping task. When comparing the number of measures improved upon by the Wii-playing group and the control group for all three tasks, the Wii-playing group consistently outperformed the control group in 18 measures compared with the control group's improvement in 6. CONCLUSIONS: This study further characterizes the association between video game playing and surgical performance. Improvements following the intervention were made in the most basic of surgical skills, most notably with the nondominant hand, suggesting that short-term playing of the Wii could improve bimanual dexterity and expedite the acquisition of basic surgical skills.

Clinical grading of the pivot shift test correlates best with tibial acceleration.

PURPOSE: Recently, different measurement systems have been developed to quantitatively measure the pivot shift in vivo. These systems lack validation and a large inter-examiner variability for the manually performed pivot shift test exists. The purpose of this study was to perform objective measurements of the pivot shift using three different measurement devices and to examine the correlation of the measurements with clinical grading of the pivot shift. METHODS: A cadaver knee on a whole lower body specimen was prepared to display a high-grade pivot shift. The pivot shift tests were performed three times by 12 blinded expert surgeons using their preferred technique. Simultaneous data samplings were recorded using three different measurement devices: (1) electromagnetic tracking system using bone-attached and skin-fixed sensors, respectively, (2) triaxial accelerometer system, and (3) simple image analysis. The surgeons graded the knee clinically using pivot shift grades I-III. Correlations were calculated using the Spearman's rank correlation coefficient. RESULTS: The expert surgeons average clinical grading was 2.3 (SD ± 0.5). Clinical grading displayed best correlation with the acceleration of reduction as measured by electromagnetic tracking system with bone-attached sensors (r = 0.67, P < 0.05). Similar correlation coefficient was found for the acceleration of reduction (r = 0.58, P = 0.05) and the "jerk" component of acceleration (r = 0.61, P < 0.05) measured by means of the triaxial accelerometer system. CONCLUSION: The pivot shift can be quantified by several in vivo measurement devices. Best correlation with clinical grading was found with tibial acceleration parameters. Future studies will have to analyze how quantitative parameters can be utilized to standardize clinical grading of the pivot shift. LEVEL OF EVIDENCE: Diagnostic study, Level II.

Evaluation of the effects of platelet-rich plasma (PRP) therapy involved in the healing of sports-related soft tissue injuries.

Musculoskeletal injuries are the most common cause of severe long-term pain and physical disability, and affect hundreds of millions of people around the world. One of the most popular methods used to biologically enhance healing in the fields of orthopaedic surgery and sports medicine includes the use of autologous blood products, namely, platelet rich plasma (PRP). PRP is an autologous concentration of human platelets to supra-physiologic levels. At baseline levels, platelets function as a natural reservoir for growth factors including platelet-derived growth factor (PDGF), epidermal growth factor (EGF), transforming growth factor-beta 1 (TGF-ß1), vascular endothelial growth factor (VEGF), basic fibroblast growth factor (FGF), hepatocyte growth factor (HGF), and insulin-like growth factor (IGF-I). PRP is commonly used in orthopaedic practice to augment healing in sports-related injuries of skeletal muscle, tendons, and ligaments. Despite its pervasive use, the clinical efficacy of PrP therapy and varying mechanisms of action have yet to be established. Basic science research has revealed that PRP exerts is effects through many downstream events secondary to release of growth factors and other bioactive factors from its alpha granules. These effects may vary depending on the location of injury and the concentration of important growth factors involved in various soft tissue healing responses. This review focuses on the effects of PrP and its associated bioactive factors as elucidated in basic science research. Current findings in PRP basic science research, which have shed light on its proposed mechanisms of action, have opened doors for future areas of PrP research.

Individualized anatomic anterior cruciate ligament reconstruction.

Arthroscopic anterior cruciate ligament reconstruction (ACL-R) is a technique that continues to evolve. Good results have been established with respect to reducing anteroposterior laxity. However, these results have come into question because nonanatomic techniques have been ineffective at restoring knee kinematics and raised concerns that abnormal kinematics may impact long-term knee health. Anatomic ACL-R attempts to closely reproduce the patient's individual anatomic characteristics. Measurements of the patient's anatomy help determine graft choice and whether anatomic reconstruction should be performed with a single- or double-bundle technique. The bony landmarks and insertions of the anterior cruciate ligament (ACL) are preserved to assist with anatomic placement of both tibial and femoral tunnels. An anatomic single- or double-bundle reconstruction is performed with a goal of reproducing the characteristics of the native ACL. Long-term outcomes for anatomic ACL reconstruction are unknown. By individualizing ACL-R, we strive to reproduce the patient's native anatomy and restore knee kinematics to improve patient outcomes.
