RESUMO
PURPOSE: Multi-stranded hamstring-tendon autografts have been widely used for anterior cruciate ligament reconstruction (ACLR) surgeries. Recently, smaller diameter hamstring autografts have been linked with the risk of failure or graft rupture. However, there is limited evidence concerning the optimal diameter of the hamstring autografts for ACLR. The current systematic review and meta-analysis analysed the association of ACLR failure with the diameter of hamstring autografts. METHODS: A systematic search of three major scientific databases (Pubmed, EMBASE, and Cochrane library) was conducted to identify studies that presented ACLR failure-related outcomes with different diameters of hamstring autografts. The pooled data from the included studies were analysed to investigate the association between ACLR failure and the cut-off diameters of 6, 7, 8, and 9 mm. Subgroup analyses based on the level of evidence and follow-up duration were also performed at each cut-off diameter. RESULTS: Of the 2282 studies screened, 16 reported failure rates with hamstring autografts of different diameters, 15 of which were included in the meta-analysis. A graft diameter ≥ 7 mm was associated with significantly lower ACLR failure rates than a graft diameter < 7 mm (p = 0.005), based on pooled data of 19,799 cases. Age < 20 years and higher physical activity were associated with significantly higher ACLR failure rates. CONCLUSION: The current systematic review suggests that the hamstring graft diameter for ACLR should be more than 7 mm considering the significantly higher failure rates with graft diameters less than 7 mm. LEVEL OF EVIDENCE: Level IV.

OBJECTIVES: Low-molecular weight heparin (LMWH) has been approved for treatment of deep venous thrombosis and venous thromboembolism which are associated with cancer. The efficacy and safety of apixaban in management of acute deep venous thrombosis associated with active malignancy is still an unresolved issue. The aim of our study is to evaluate the efficacy and safety of apixaban in patients with acute deep venous thrombosis and active malignancy compared with weight adjusted subcutaneous LMWH. METHODS: Of 138 randomized patients, 100 patients with active malignancy presenting with acute deep venous thrombosis and still treated with chemotherapy were assigned to either oral apixaban therapy or subcutaneous low-molecular weight heparin (enoxaparin) through randomized clinical study in 1:1 ratio. All patients were followed up to six months. The primary end point was major bleeding, while secondary end points were recurrent deep venous thrombosis or venous thromboembolism, minor or non-fatal bleeding and mortality related to massive pulmonary embolism. RESULTS: Both groups were matched regarding their baseline demographic, clinical and laboratory characteristics. We had 84 patients with metastatic cancer (stage 4). The most prevalent type of malignancy was cancer colon (42% of cases). There was no significant difference between both groups regarding the incidence of primary and secondary end points. There were no reported mortality cases related to massive pulmonary embolism in both groups. CONCLUSION: In this limited study, there was no difference in the major bleeding, recurrent deep venous thrombosis or minor bleeding in patients with active malignancy when treated with either apixaban or LMWH.Trial registration: ClinicalTrials.gov (NCT04462003).

PURPOSE: To examine the association of self-esteem with the body mass index (BMI), perceived body image (BI), and desired BI of college-age Saudi females. METHODS: A cross-sectional study was conducted with 907 randomly selected females using a multistage stratified cluster sampling technique. Self-esteem and BI were assessed using the Rosenberg Self-Esteem Scale and Stunkard Figure Rating Scale, respectively. RESULTS: The prevalence of low self-esteem was only 6.1% among college females; however, this percentage was higher (9.8%) among overweight or obese participants. The total self-esteem scores showed significant negative correlations with actual BMI and perceived BI, but not with desired BI. Meanwhile, multivariate analyses revealed significant differences in total self-esteem scores according to obesity/overweight status and perceived BI group, but not desired BI group. CONCLUSION: Despite the high prevalence of overweight and obesity in Saudi Arabia, few Saudi college females have low self-esteem. In addition, body weight, BMI, perceived BI, and the BMI corresponding to the perceived BI all significantly differed between females with low self-esteem and those with normal self-esteem. LEVEL OF EVIDENCE: Level V, cross-sectional descriptive study.

PURPOSE: To quantitatively evaluate the rate, type, and level of contamination of anterior cruciate ligament (ACL) hamstring autografts after harvesting and preparation or dropping onto the operating room (OR) floor. METHODS: Two hamstring autograft specimens were prospectively retrieved from each graft in a consecutive series of 50 patients undergoing primary isolated ACL reconstruction (100 specimens total). One specimen was retrieved immediately after harvesting and dropped onto the OR floor (dropped group). The other was retrieved just after graft implantation and before fixation (control group). Each specimen was incubated for aerobic and anaerobic growth, and the number of colony-forming units (CFU)/g was measured. Patients' clinical course was monitored for signs of surgical site infection (SSI). RESULTS: The control and dropped groups had positive culture rates of 11/50 (22%) and 16/50 (32%), respectively, with no significant difference between groups (n.s.). The most common organism in the control group was Staphylococcus epidermidis (45.5%) followed by S. aureus (36.4%). In the dropped group, the most common organism was S. epidermidis (31.3%) followed by Bacillus species (25%). The median (range) CFU/g among positive specimens in the dropped and control groups was 65 (8-150) and 10 (2-60), respectively (P = 0.0003). No patient developed postoperative SSI. CONCLUSION: Intraoperative hamstring autograft contamination rates were high. Hence, routine prophylactic decontamination of all hamstring autografts after harvesting and preparation and before implantation is recommended. LEVEL OF EVIDENCE: Controlled laboratory study.

RESUMO
Psoriasis, a chronic inflammatory skin condition, and metabolic disorders, such as obesity, diabetes, and dyslipidemia, have long been recognized as distinct clinical entities. However, emerging evidence suggests a complex bidirectional relationship between these seemingly unrelated conditions. Psoriasis is characterized by an accelerated skin cell turnover, resulting in the formation of erythematous plaques with silvery scales. Metabolic disorders, on the other hand, encompass a range of conditions associated with abnormal metabolic processes, including insulin resistance, dyslipidemia, and chronic low-grade inflammation. It is intriguing to note that psoriasis is commonly associated with several metabolic comorbidities, with a higher prevalence observed in individuals with obesity, type 2 diabetes, and metabolic syndrome. Mounting evidence suggests that chronic inflammation plays a pivotal role in both psoriasis and metabolic disorders. Shared inflammatory mediators, such as tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6), and C-reactive protein (CRP), have been implicated in the pathogenesis of both conditions. Moreover, adipose tissue-derived hormones, known as adipokines, including leptin and adiponectin, exert modulatory effects on immune responses and may contribute to the link between psoriasis and metabolic abnormalities. Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, a comprehensive search across databases identified 16 eligible studies (1975-2023), totaling 6,623,379 participants. Inclusion criteria encompassed peer-reviewed observational studies focusing on adults and specified outcomes. Data extraction, quality assessment (Newcastle-Ottawa scale (NOS)), meta-analyses, and heterogeneity evaluations were conducted using rigorous methods. Psoriasis displayed a significant association with diabetes mellitus (DM, 18% increased incidence), hypertension (HTN, 35%), hyperlipidemia (19%), and obesity (25%). Substantial heterogeneity was observed in meta-analyses, particularly for DM. The NOS indicated varied study quality, with some studies categorized as a high or moderate risk of bias.
RESUMO
BACKGROUND: The COVID-19 vaccine has been available and well acceptable among the Saudi population since its introduction in 2020; however, concerns still remain regarding the confidence of doctors in giving such vaccines. RESEARCH QUESTION: How confident are physicians in the Kingdom of Saudi Arabia about giving counseling and advice for patients regarding COVID-19 disease and COVID-19 vaccines? OBJECTIVE: To determine how confident Saudi Arabian doctors are in their ability to advise patients on the COVID-19 illness and COVID-19 vaccines. AIM: To assist the health authorities in the Kingdom of Saudi Arabia in developing and implementing programs to improve doctors' skills and knowledge in giving advice to patients about the COVID-19 vaccine. METHOD: The research employed an online cross-sectional study methodology to gather insights from doctors employed at hospitals, healthcare centers, and clinics across the Kingdom of Saudi Arabia. The inclusion criteria encompassed doctors actively engaged in healthcare settings, while the exclusion criteria were applied to those who had never encountered COVID-19 patients and those who declined participation in the study. RESULTS: It was found that doctors were confident that there's a potential for adverse effects that are not yet seen in vaccine trials. Further results showed that primary health care doctors are more confident about the common side effects associated with the approved vaccines. CONCLUSION: Most doctors were confident about the vaccine, yet they also know that there are some hidden side effects that are not yet discovered. Since patients trusted doctors as the main source of information about the vaccine, the study provided evidence to emphasize the rule of doctors as a reliable source of information.
RESUMO
INTRODUCTION: Lateral opening wedge high tibial osteotomy is a rarely employed surgical technique used for the treatment of lateral knee pain and degeneration in the setting of genu valgum. There exists little evidence of the suitability of this procedure for patients requiring osteotomies with a small correction. MATERIALS AND METHODS: A case series of 23 patients (24 knees) undergoing lateral opening wedge high tibial osteotomy with a minimum follow-up of 2 years was performed between 2002 and 2008. A surgical technique avoiding the need for fibular osteotomy is described. Adverse events, patient-reported outcomes and radiographic measures of alignment were assessed at baseline, at 6 months postoperatively, and at time of final follow-up. A subgroup of 12 patients also underwent 3D gait analysis at the same time points. RESULTS: The mean follow-up was 52 months (±20.4). Statistically and clinically significant improvements were identified in the lower extremity functional scale [mean change (95%CI) = 10 (2.4, 17.6)], and in the knee injury and osteoarthritis outcome score [mean change (95%CI) = 10.9 (0.5, 21.4)]. Mechanical axis changed from 2.4 ± 2.4° valgus to 0 ± 2.6° varus (p<0.001), anatomical axis from 6.9 ± 2.8° to 4.7 ± 2.5° valgus (p < 0.001), with weight-bearing line offset changing from 60.2 ± 11.4% to 49.5 ± 12.4% (p < 0.001). Change in lateral tibial slope, from 6.5 ± 2.2° to 7.5 ± 2.3°, was very small and not statistically significant (n.s.). The peak knee adduction moment during gait significantly increased [mean change (95%CI) = 0.72%BW*Ht (0.42, 1.02), suggesting a medial shift in dynamic knee joint load. Two patients underwent total knee arthroplasty during the study period. CONCLUSIONS: Lateral opening wedge high tibial osteotomy is a viable surgical option for patients with lateral knee pain and valgus malalignment requiring small degrees of correction. LEVEL OF EVIDENCE: IV.

RESUMO
BACKGROUND: Portal positioning in arthroscopic anterior cruciate ligament reconstruction is critical in facilitating the drilling of the femoral tunnel. However, the traditional approach has limitations. A modified inferior anteromedial portal was developed. Therefore, this study aims to compare the modified and conventional far anteromedial portals for femoral tunnel drilling, assessing factors such as tunnel length, inclination, iatrogenic chondral injury risk, and blowout. MATERIAL AND METHODS: Patients scheduled for hamstring autograft-based anatomical single-bundle arthroscopic anterior cruciate ligament reconstruction were divided into two groups: modified and far anteromedial groups. Primary outcomes include differences in femoral tunnel length intraoperatively, tunnel inclination on anteroposterior radiographs, and exit location on lateral radiographs. Secondary outcomes encompass tunnel-related complications and reconstruction failures. To identify potential risk factors for shorter tunnel lengths and posterior exits, regression analysis was conducted. RESULTS: Tunnel parameters of 234 patients were analyzed. In the modified portal group, femoral tunnel length and inclination were significantly higher, with tunnels exhibiting a more anterior exit position (p < 0.05). A higher body mass index exerted a negative influence on tunnel length and inclination. However, obese patients in the modified portal group had longer tunnels, increased inclination, and a lower risk of posterior exit. Only a few tunnel-related complications were observed in the far anteromedial group. CONCLUSION: The modified portal allowed better control of tunnel length and inclination, ensuring a nonposterior femoral tunnel exit, making it beneficial for obese patients.
RESUMO
BACKGROUND: While female participation has improved in several surgical specialties over time globally, no such increase has been observed in orthopaedic surgery over the past decades. The potential barriers to female participation are likely present from the beginning of medical education. Therefore, this study assessed the apparent lag in equal representation among men and women in orthopaedic surgery in the Kingdom of Saudi Arabia. METHODS: This cross-sectional study used a questionnaire survey to investigate medical students' and interns' perceptions of women participating in orthopaedic surgery, their subspeciality preferences, and barriers preventing them from pursuing an orthopaedic career. The responses were analysed to understand general perceptions, gender-based differences, impact of clinical experiential learning, and exposure to orthopaedic surgery. RESULTS: Approximately 565 medical students (49% females, 51% males) participated in the survey. Only 17% of students (11% females, 23% males) considered orthopaedic surgery as their future career option. While 31% of female and 17% of male students disagreed with the concept of female-appropriate orthopaedic subspecialties, most of the remaining male and female students perceived paediatric orthopaedics as a female-appropriate subspecialty. Concerning equal representation of women, gender bias and lack of a strong physique were the most frequently selected barriers by female and male students, respectively. Patient preference for male orthopaedicians, gender discrimination, social and family commitments, and need for physical strength were all perceived as barriers for women in orthopaedics. Overall, clinical experience and orthopaedic exposure did not significantly improve the likelihood of female students in choosing orthopaedic surgery as a career. CONCLUSIONS: The bias against women in orthopaedic careers is prevalent among medical students early in their academic years. Clinical experience and exposure to orthopaedic surgery should be improved to make a significant impact on female participation in orthopaedic careers. Career building efforts in terms of improved career opportunities, career counselling, flexible working hours, social and family related adjustments and implementation of mentorship/research/fellowship programmes for females are needed to reduce gender discrimination and improve female orthopaedic participation. Furthermore, process improvements may yield greater flexibility for women pursuing the challenging field while accommodating other barriers faced by women in orthopaedic surgery.

BACKGROUND: Little is known about the impact of hypothyroidism and its contribution to learning difficulties and academic performance in college-age students. OBJECTIVE: The objective is toassess the frequency of hypothyroidism and its associations with academic performance in college-age students. METHODS: A cross-sectional study included 395 students studying across various Jeddah universities and selected by non-probability convenient sampling. Students self-answered the survey using Google Forms. The survey included demographic data, thyroid data, academic achievement as measured by overall grade point average (GPA), and student persistence as measured by academic failure and delay. RESULTS: Three hundred ninety-five students were included, their median age was 23 years (17-33), 96 were males (24.3%) and 299 were females (75.7%). Their median GPA was 4 (2.76-4). Thirty-two students (8.1%) had been treated for hypothyroidism and eight students (25.8%) were non-compliant with therapy. Odds of hypothyroidism increased among females (OR 3.33, 95% CI: 0.99-10.78, p=0.048), older age (OR 2.60, 95% CI: 1.33-5.77, p=0.009), those with a positive family history of thyroid illnesses (OR 5.49, 95% CI: 2.30-13.07, p<0.001), and those with academic failure (OR 3.31, 95% CI: 1.43-7.30, p=0.003) and academic delay (OR 2.83, 95% CI: 1.14-7.05, p=0.020). There was no significant association between hypothyroidism and GPA (OR 2.42, 95% CI: 0.83-7.77, P=0.092). CONCLUSION: Hypothyroidism was prevalent among college students (8%), especially among older females. Hypothyroidism was associated with difficult student persistence, but this association did not reflect on their overall academic achievement. Incompliance with thyroid replacement therapy may be a common issue among hypothyroid patients. Further studies should focus on specific tests of the cognitive function of different learning domains and the role of treatment.
RESUMO
Background To provide effective oral health care to patients and healthy individuals, it is critical to recognize prevalent myths. Most myths cause patients to follow the wrong protocol in dentistry, which can make treatment difficult for the dentist. This study aimed to assess dental myths among the Saudi Arabian population in Riyadh. Methodology A descriptive cross-sectional questionnaire survey was conducted among Riyadh adults between August and October 2021. Saudi nationals aged 18-65 living in Riyadh without cognitive, hearing, or vision impairments and with limited or no trouble interpreting the questionnaire were surveyed. Only participants who consented to participate in the study were included. JMP Pro 15.2.0 was used to evaluate survey data. Frequency and percentage distributions were used for dependent and independent variables. The chi-square test evaluated the statistical significance of the variables, with a p-value of 0.05 being considered statistically significant. Results A total of 433 participants completed the survey. Half of the sample (50%) were aged 18-28; 50% were men; and 75% had a college degree. Higher-educated men and women did better on the survey. In particular, 80% of the participants believed "teething causes fever." "Placing a (pain killer) tablet on a tooth reduces pain" was believed by 34.40% of the participants, and 26% thought pregnant women should not get dental work. Lastly, 79% of the participants believed that "infants obtain calcium from their mother's teeth and bone." Most sources of these pieces of information were online (62.60%). Conclusions Nearly half of the participants believe in dental health myths, and as a result, people follow unhealthy practices. This results in long-term health consequences. The government and health professionals must prevent the spread of such misconceptions. In this regard, dental health education may be helpful. Most of this study's crucial findings are consistent with those of prior studies, indicating its accuracy.
RESUMO
Current evidence indicates that undergraduate medical students display deficits in musculoskeletal physical examination skills (MPES). While various instructional methods are recommended for teaching clinical skills, effective methods for teaching MPES have not been established. This study compared the effectiveness of a multimodal teaching approach incorporating video-based learning, interactive small-group teaching, hands-on practicing, peer-assisted learning, formative assessment, and constructive feedback with traditional bedside teaching in developing undergraduate orthopedic MPES. Participants were 151 fifth-year medical students divided into two groups. One group received multimodal teaching, and the other received traditional bedside teaching. In both groups, the participants learned how to physically examine the knee and shoulder. The primary outcome was objective structured clinical examination (OSCE) scores, while the secondary outcomes included teaching sessions' total durations, facilitator's demonstration time, participants' practice time, and proportion of students with passing checklist scores and global ratings-based assessments for the two teaching approaches. The multimodal teaching group had significantly higher OSCE scores (checklist scores, global ratings, and passing rates; p = 0.02, 0.02, 0.01, respectively) than the comparison group. Individual OSCE component assessments showed significant improvements in the special musculoskeletal physical examination test. The overall duration and amount of participants' hands-on time were significantly longer for the multimodal than for the traditional bedside teaching group (p = 0.01 and 0.01, respectively), and the facilitator's demonstration time was significantly shorter (p = 0.01). The multimodal learner-centered teaching approach evaluated in this study was effective for teaching MPES. It appeared to maximize learner engagement through enhancing interactions and providing increased time to engage in hands-on practice. This teaching approach improved MPES levels, maximized teaching efficiency for scenarios with limited instruction time and resources, and enhanced competency of undergraduate medical students in performing special musculoskeletal physical examinations compared to traditional bedside teaching.

BACKGROUND: The increase in the enrollment of orthopedic surgery residents in multiple fellowship programs has gained considerable interest. Different factors may determine the specialty and number of fellowships trainees enroll in. This study aimed to elucidate these factors and determinants among orthopedic trainees. METHODS: This is a descriptive cross-sectional study, which was conducted among orthopedic surgical trainees (residency and fellowship training programs) in Saudi Arabia, between March 2021 and May 2021. The data were obtained through an online anonymous questionnaire aiming to clarify the most influential factors that determine the number of fellowships trainees choose, as well as to compare the choice of single fellowships with those of multiple ones. RESULTS: Two hundred and fifty orthopedic trainees (201 (80%) males and 49 (20%) females) completed the survey. Among them, 216 (86%) and 34 (14%) were residents and fellows, respectively, and 81% (n = 203) of the trainees preferred multiple fellowship training, and 22% (n = 47) preferred a single fellowship specialty. Notably, the male trainees preferred multiple fellowships to a single one (85% vs. 62%, p-value = 0.001), while the female trainees preferred single fellowships to multiple ones (38% vs. 15%, p-value = 0.001). The expected rate of income (17% vs. 9%), job opportunities in the private sector (17% vs. 9%), and availability and guarantee of jobs (33% vs. 23%) were the most significant factors that influenced the choices of the participants toward enrolling in multiple fellowships (p-values = 0.001, 0.001, and 0.004, respectively). CONCLUSIONS: The study demonstrated that most of the orthopedic trainees in Saudi Arabia prefer the pursuits of multiple fellowship programs. Further, the female trainees preferred single fellowships, whereas the male ones preferred multiple fellowships. The main influencing factors for pursuing multiple fellowships were determined to be private job opportunities, financial gains, and job guarantees.

Objective: Understanding gender-based preferences and factors influencing fellowship and subspecialty choice might help maximize gender diversity in orthopedic surgery. This study aims to identify the differences between male and female orthopedic trainees' future career plans. It also examines the factors and determinants that influence selection of fellowship specialties in Saudi Arabia. Methods: This cross-sectional multicenter study recruited orthopedic surgical trainees from multiple training centers. The survey was completed by 270 participants; 20 residents were excluded because they were unsure of their future career interests or preferred fellowships in general orthopedic practice. The participants were either postgraduate orthopedic residents or fellows who already enrolled in postgraduate residency and/or fellowship training program. A total of 201 (80% of 250 participants) were male and 49 (20%) were female. Results: The orthopedic subspecialities and fellowship preferences and their influencing factors varied considerably across genders. Pediatric orthopedics and hand and upper extremity were top sub-specialties preferences among women while arthroscopy and sports medicine, arthroplasty, and trauma were the top preferences among men. Women preferred to practice single subspeciality while men preferred to do multiple fellowships and practiced different orthopedic subspecialities. The expected income, private-sector job opportunities, and hospital needs were the most significant factors influencing subspecialty and future career preferences among men while personal interest and social and family commitments were the most influential factors for women. Conclusions: This study addresses the knowledge gap regarding gender-based subspecialty preferences and the factors influencing them. The results can inform strategy development for addressing women's needs and interests in orthopedic surgery as well as the shortages of orthopedic surgeons in some subspecialties. Furthermore, these data may assist directors of training centers in analyzing expected future demands on fellowship training programs and addressing the training gap in all subspecialties and career counseling.
RESUMO
Purpose: The Mini Clinical Evaluation Exercise (mini-CEX) is a brief and direct observational assessment of trainee-patient interactions that helps to assess several clinical domains. There is limited evidence of mini-CEX implementation in orthopedics and undergraduate perceptions toward such an approach. This study investigated the perception of mini-CEX among undergraduate medical students through a questionnaire-based survey in an orthopedic outpatient setting. Patients and Methods: Undergraduate medical students completing their orthopedic clinical posting were invited to participate in an anonymous, self-administered questionnaire written in English to evaluate their perceptions toward mini-CEX implementation in the orthopedic outpatient setting for the 2016-2017 academic session. The questionnaire comprised 28 closed-ended questions with a five-point Likert rating-scale, and five open-ended questions. The survey responses were analyzed for reliability, validity, and quantitative and qualitative analyses. Results: A total of 350 students completed the questionnaire; the questionnaire was proven to be valid and reliable. The closed-ended questions were designed to assess the knowledge of the mini-CEX as an assessment tool. The participants demonstrated a satisfactory understanding of the mini-CEX methodology, purpose, clarity, comprehensiveness, and as a self-assessment tool for undergraduate medical students. Instructor support for the implementation of mini-CEX appeared inadequate and was rated with non-confidence among most students. Most participants appreciated better clinical skills, which was reflected through improvements in clinical exam preparation, the Objective Structured Clinical Examination, and clinical judgment. Conclusion: Undergraduate medical students perceived the mini-CEX as an effective tool for clinical teaching in an outpatient orthopedic setting. However, most students indicated suboptimal instructor involvement in the teaching and assessment process; this raises concerns regarding inadequate direct observation and limited feedback for student performance. Additional measures are needed to ensure high quality clinical encounters, teacher training, integration with other assessment tools, and standardized coverage mini-CEX implementation in orthopedics.
RESUMO
Introduction: Video-based learning has gained prominence in medical education and, more recently, in musculoskeletal teaching. This study investigated medical students' perceptions of the effectiveness of online video-based learning for musculoskeletal physical examination skills. Methods: For one academic year, undergraduate medical students were instructed online through video-based learning before bedside teaching about the physical examination of knee and shoulder joints. At the end of the course, the students participated in a survey to assess their perceptions of the online video-based learning module using a pre-validated questionnaire. The questionnaire consisted of closed-ended and open-ended questions. The closed-ended question responses were assessed using a Likert scale; the open-ended responses were analyzed qualitatively. Results: In total, 242 out of 310 students who participated in the online video-based learning responded to the survey. Most students found the teaching approach to be satisfactory and preferable to traditional teaching methods. However, they also felt that these modules could not replace hands-on practice. The most helpful aspects of the training modules were a better understanding of the specific tests, technique, and sequence of administering the physical examination. Perceived limitations included the inadequately addressed theoretical basis of the physical examination and the special tests, the need for more time to explain clinical anatomy, and the practical implications of the positive special tests. Conclusion: Undergraduate medical students perceive VBL as helpful for MPES learning. The positive aspects of the VBL approach in teaching MPES are that it is comprehensive, easily accessible, offers standardized teaching, save times, and it includes demonstrations of special tests, examination techniques, and the sequence and organization of the clinical examination. The main perceived limitations were lack of content regarding clinical reasoning and the anatomical basis of the clinical tests.
RESUMO
Introduction: Despite numerous articles on intraoperative contamination in total knee arthroplasty (TKA) procedures, the available data on tissue contamination are scarce and mainly based on evaluating bacteriological swabs. Methods: Two hundred and forty specimens, divided between bone and soft tissue, were obtained from 40 consecutive unilateral primaries TKAs. The specimens were evaluated for aerobic and anaerobic bacterial growth. Colony-forming units/gram (CFU/g) were calculated on the contaminated specimens to determine the level of contamination. Results: The contamination rate in intraoperative specimens was 15% during TKA. The contamination level had a mean of 10.6 and a median of 5, ranging from 1-70 CFU/g. The most common contaminating organisms in all samples were Staphylococcus aureus (38.9%) and Staphylococcus epidermidis (30.6%). No clinical infections were detected in TKAs in the follow-up period. Conclusion: The contamination rate during TKA is relatively high, despite the practice of standard preventive measures. Contamination levels, measured by CFU/g, are considered low when compared to the infection threshold of 105 reported in the literature. However, contamination should not be underestimated due to the presence of foreign bodies (implants), which are known to significantly lower this threshold. Level of evidence IV; case series .
Introdução: Apesar dos inúmeros artigos sobre a contaminação intraoperatória em procedimentos de artroplastia total do joelho (ATJ), os dados disponíveis sobre a contaminação tecidual são escassos e baseiam-se principalmente na avaliação de swabs bacteriológicos. Métodos: Duzentos e quarenta espécimes, divididos entre ossos e tecidos moles, foram obtidos de 40 ATJ primárias unilaterais consecutivas. Os exemplares foram avaliados quanto ao crescimento bacteriano aeróbio e anaeróbio. As unidades formadoras de colônias/grama (UFC/g) foram calculadas nas amostras contaminadas para determinar o nível de contaminação. Resultados: A taxa de contaminação em espécimes intraoperatórios foi de 15% durante a ATJ. O nível de contaminação teve uma média de 10,6 e uma mediana de 5 variando de 1-70 UFC/g. Os organismos contaminantes mais comuns em todas as amostras foram Staphylococcus aureus (38,9%) e Staphylococcus epidermidis (30,6%). Nenhuma infecção clínica foi detectada nas ATJ durante o período de acompanhamento. Conclusão: A taxa de contaminação durante a ATJ é relativamente alta, apesar da prática de medidas preventivas padrão. Os níveis de contaminação, medidos por UFC/g, são considerados baixos quando comparados ao limiar de infecção de 105, relatado na literatura. No entanto, a contaminação não deve ser negligenciada devido à presença de corpos estranhos (implantes) que são conhecidos por reduzir significativamente esse limiar. Nível de evidência IV; series de casos.
RESUMO
Background: Sports medicine is one of the most popular orthopaedic specialties, with more fellowship applicants than in any other subspecialty of orthopaedics. Purpose: To investigate the factors influencing orthopaedic trainees to complete their fellowships and subsequently subspecialize in sports medicine in Saudi Arabia, as well as to compare the motivational factors of trainees planning to pursue sports medicine versus other orthopaedic specialties. Study Design: Cross-sectional study. Methods: An online anonymous questionnaire was distributed to 400 orthopaedic surgical trainees from 44 training centers (residency and fellowship training programs) across Saudi Arabia. The questionnaire identified trainees planning to select sports medicine as their career and the most influential factors affecting their choice; items exploring the influential factors were answered on a 5-point Likert-type scale. A comparison of responses was performed with candidates aiming to pursue other orthopaedic specialties. The chi-square or Fisher exact test was used to compare demographic parameters and the percentage of "agree" and "strongly agree" responses between trainees opting for sports medicine fellowships and those choosing other fellowships. Results: Of the 400 potential participants, 250 orthopaedic trainees (response rate, 63%) completed the survey (201 [80%] male and 49 [20%] female). Sports medicine was the most coveted specialty among trainees, with 70 (28%) participants opting for it as their career choice. The most prominent factors for the decision included disease prognosis and surgical outcomes (90%), personal interest (87%), experience during residency training (83%), type of surgical skills (81%), disease pathology and patient population (77%), expected workload and lifestyle (73%), role model or mentor (70%), and patient volume and variety of cases (67%). Significant differences compared with trainees who preferred other orthopaedic specialties included role model/mentor impact (70% vs 54%), expected rate of income (60% vs 47%), and private sector job opportunities (64% vs 45%) (P = .025, .034, and .020, respectively). Conclusion: Study findings indicated that a significant percentage of orthopaedic trainees in Saudi Arabia choose to specialize in sports medicine. Role model/mentorship, private sector job opportunities, and expected rate of income were the most influential when compared with the motivations of trainees not choosing sports medicine.
