Abstract
BACKGROUND Female sports participation continues to rise; however, inequalities between male and female athletes still exist in many areas and may extend into medical research. PURPOSE The purpose of this study was to (1) compare the number of published studies evaluating male versus female athletes in various sports and (2) identify which co-ed sports currently underrepresent female athletes in the sports medicine literature. STUDY DESIGN Systematic review; Level of evidence, 4. METHODS All nonreview research studies published from 2017 to 2021 in 6 top sports medicine journals were considered for inclusion. Sports medicine studies were included that isolated athletes, reported study outcomes specific to male and/or female patients, provided study outcomes for specific sports, and evaluated ≤3 different sports. The total number of studies reporting on male and/or female athletes were compared for all sports, and odds ratios (ORs) were calculated. Comparisons of study design, level of sports participation, outcomes assessed, and study quality were also made according to participant sex. RESULTS Overall, 669 studies were included the systematic review. Most studies isolated male athletes (70.7%), while 8.8% isolated female athletes and 20.5% included male and female athletes. Female athletes were more frequently studied in softball and volleyball, while male athletes were more commonly researched in baseball, soccer, American football, basketball, rugby, hockey, and Australian football. Notably, male athletes were largely favored in baseball/softball (91% vs 5%; OR = 18.2), rugby (72% vs 5%; OR = 14.4), soccer (65% vs 15%; OR = 4.3), and basketball (58% vs 18%; OR = 3.2). CONCLUSION Sports medicine research has favored the evaluation of male athletes in most sports, including the majority of co-ed sports. Potential reasons for this inequality of research evaluation include availability of public data and database data, financial and promotional incentives, a high percentage of male sports medicine clinicians and researchers, and sex biases in sport. While the causes of these differences are multifaceted, researchers should consider both sexes for study inclusion whenever possible, and journals should support a more balanced representation of research publications regarding male and female athletes.

Abstract
BACKGROUND Sex differences in sports medicine are well documented. However, no studies to date have reviewed the rate at which sex is reported and analyzed in the athlete-specific orthopaedic sports medicine literature. PURPOSE To determine the rates of reporting and analyzing patient sex in athlete-specific sports medicine literature. STUDY DESIGN Systematic review; Level of evidence, 4. METHODS Articles published by the 3 journals of the AOSSM (American Journal of Sports Medicine [AJSM], Orthopaedic Journal of Sports Medicine, and Sports Health: A Multidisciplinary Approach) between 2017 and 2021 were considered for inclusion. Original sports medicine research studies that isolated athletes were included. Studies that isolated sports that are predominantly single sex at the college and/or professional levels (football, baseball, softball, and wrestling) were excluded. RESULTS Of the 5140 publications screened, 559 met the inclusion criteria. In total, 93.9% of all studies reported patient sex, and 34.7% of all studies analyzed patient sex. However, 143 studies only included males and 50 studies only included females (n = 193). When excluding these single-sex studies, analysis of the remaining 366 studies found that the rate of sex-specific analysis increased to 53.0%. Rates of reporting patient sex did not significantly differ by journal or by year. Similarly, rates of analyzing patient sex did not differ by year, but Sports Health analyzed sex the most frequently, and AJSM analyzed sex the least frequently (P = .002). Studies that isolated college (84.1%), youth (66.7%), or recreational (52.6%) athletes analyzed sex at or above the overall rate of 53.0%, but studies of elite athletes (35.7%) tended to analyze sex less frequently. CONCLUSION Patient sex is well reported in the athlete-specific sports medicine literature (93.9% of included studies reported sex), demonstrating that most studies include sex as a demographic variable. However, patient sex was analyzed only in 53.0% of studies that included both male and female patients. Given that athlete-specific sex differences are known to exist within the field of sports medicine, many studies that could benefit from using patient sex as a variable for analysis likely fail to do so.

Abstract
Background Elbow capsular release can be performed arthroscopically or through an open method to improve range of motion (ROM). However, it is unclear how frequently patients require an open capsular release after unsatisfactory results from an arthroscopic release. Purpose/Hypothesis The purpose of this study was to determine the percentage of patients who underwent an arthroscopic elbow release for loss of motion who then required a repeat elbow capsular release or other subsequent surgery on the same elbow. It was hypothesized that patients who underwent arthroscopic elbow release would rarely (<5%) require a subsequent elbow release. Study Design Case series; Level of evidence, 4. Methods Patients who underwent arthroscopic elbow capsular release from January 1, 2010, to December 31, 2019, were identified by chart review and procedure code. Demographic parameters, pre- and postoperative ROM, and surgical history were collected by chart review. Follow-up data included patient satisfaction and the Timmerman-Andrews (TA) elbow score. Data were compared between patients who did and those who did not require subsequent elbow surgery. Results Overall, of 140 study patients (116 male, 24 female; mean age, 49.6 years), 18 (12.9%) required subsequent surgery, including 6 capsular releases (4.3%; 1 open and 5 arthroscopic). The most common follow-up procedure was ulnar nerve releases/transpositions (n = 7). Total arc of elbow motion (flexion to extension) improved by a mean of 51.4°. The mean TA score was 76.5 ± 20.4 at a mean of 5.25 years postoperatively. Mean satisfaction score was 77.6 ± 26.3. In this study, 82.4% of patients stated that their symptoms either improved or resolved completely. Patients who required subsequent surgery had a significantly lower preoperative total arc of elbow motion versus those who did not require subsequent surgery (P = .046). There was no difference between the groups in symptom resolution, satisfaction, ROM, or TA score (P ≥ .279 for all). Conclusion After arthroscopic elbow release, <5% of patients required a repeat elbow capsular release, 12.9% required some form of follow-up elbow surgery, and 4.3% had a new injury of the elbow. Overall, patients saw improvement in elbow ROM, but many still had residual symptoms from their underlying disease after arthroscopic elbow capsular release.

Abstract
Background Bone-patellar tendon-bone (BTB) and hamstring autografts are the most common grafts used for anterior cruciate ligament (ACL) reconstruction. Patient preferences should be accounted for as a part of shared decision making. Purpose/Hypothesis The purpose of this study was to perform a discrete choice experiment that evaluated patient preferences toward ACL autografts. We hypothesized that there would be no difference in patient preferences between groups. Study Design Cross-sectional study. Methods Patients aged 18 to 25 years who underwent shoulder arthroscopy at a single institution between 2013 and 2019 were included in the study as a proxy for healthy controls. Patients with a history of ACL tear were excluded. A discrete choice experiment was developed from a literature search and used the following data points as they pertain to BTB or hamstring autograft: risk of developing a significant complication, return-to-play rate, risk of anterior knee pain with kneeling, and risk of additional surgery due to graft failure. Included patients completed a custom survey in which they were asked to choose between "surgery A" (hamstring) and "surgery B" (BTB). Results A total of 107 participants were included in the analysis. Of these participants, 39 (36.5%) chose surgery A (hamstring) and 68 (63.6%) chose surgery B (BTB). When comparing the hamstring group with the BTB group, there was no significant difference in age, sex, body mass index, race, level of education, or employment status. However, 80.5% of self-reported athletes preferred BTB (P = .008). When controlling for age, sex, and body mass index, patients in the BTB group were more likely to rate return to sport (risk ratio [RR] = 1.49 [95% CI, 1.18-1.98]; P = .001) and the risk of requiring additional surgery due to graft failure (RR = 1.26 [95% CI, 1.02-1.58]; P = .037) as highly important. Conversely, they were less likely than patients in the hamstring group to rate pain while kneeling (RR = 0.65 [95% CI, 0.98-1.05]; P < .001) and complication risk (RR = 0.75 [95% CI, 0.59-0.94]; P = .013) as important. Conclusion The study hypothesis was rejected, as patient values did affect ACL graft choice preference. Utilizing patient-selected values in a quantifiable way can benefit the shared decision-making process before ACL reconstruction.

Abstract
» Scapular dyskinesis is an alteration of normal scapular kinematics. It is essential that each patient be evaluated holistically and that sport-related factors be taken into account. » The presentation of scapular dyskinesis may be highly variable depending on the underlying etiology or associated pathology, but the onset of symptoms is often gradual. » Sport-specific literature on scapular dyskinesis is most commonly reported in the context of baseball, swimming, and tennis. Treatment is most often conservative and involves physical therapy directed at the scapular stabilizers.

Abstract
BACKGROUND Previous studies have shown that the depth of cement penetration and the presence of radiolucent lines (RLLs) correspond with the risk of aseptic loosening in total knee arthroplasty, while others have found a correlation between the viscosity of the cement and the depth of cement penetration. We compared cement marketed as high-viscosity cement (HVC) with one marketed by the same manufacturer as low-viscosity cement (LVC). We hypothesized that no significant difference would be found in depth of penetration or presence of RLLs between the two cohorts. METHODS The HVC (n = 50) and LVC cohorts (n = 50) were gathered from two sequential series of primary total knee arthroplasties using the same implants and cementing techniques. Depth of cement penetration and presence of RLL were measured in four tibial zones and were compared between cohorts. RESULTS There were no cases of aseptic loosening in either cohort at a mean of 29 months. Mean maximum cement penetration in 3 of the 4 zones was >3 mm with both cements. There was no significant difference in maximum penetration in any zone between the two cements. There were fewer tibial radiolucencies with HVC than LVC. CONCLUSION These findings suggest that the marketing description of HVC or LVC is not necessarily a factor in cement penetration. The term high viscosity should not be used as a descriptor of cement that reaches dough phase more quickly, but rather cement that has a higher viscosity at its dough phase when it is typically applied.

Abstract
Restoration of coronary blood flow after a heart attack can cause reperfusion injury potentially leading to impaired cardiac function, adverse tissue remodeling and heart failure. Iron is an essential biometal that may have a pathologic role in this process. There is a clinical need for a precise noninvasive method to detect iron for risk stratification of patients and therapy evaluation. Here, we report that magnetic susceptibility imaging in a large animal model shows an infarct paramagnetic shift associated with duration of coronary artery occlusion and the presence of iron. Iron validation techniques used include histology, immunohistochemistry, spectrometry and spectroscopy. Further mRNA analysis shows upregulation of ferritin and heme oxygenase. While conventional imaging corroborates the findings of iron deposition, magnetic susceptibility imaging has improved sensitivity to iron and mitigates confounding factors such as edema and fibrosis. Myocardial infarction patients receiving reperfusion therapy show magnetic susceptibility changes associated with hypokinetic myocardial wall motion and microvascular obstruction, demonstrating potential for clinical translation.
