Effect of anteromedial portal location on femoral tunnel inclination, length, and location in hamstring autograft-based single-bundle anterior cruciate ligament reconstruction: a prospective study.

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.

Representation of women in orthopaedic surgery: perception of barriers among undergraduate medical students in Saudi Arabia.

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.

Factors Influencing Sports Medicine as a Career Choice Among Orthopaedic Trainees in Saudi Arabia.

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.

Perception and Satisfaction of Undergraduate Medical Students of the Mini Clinical Evaluation Exercise Implementation in Orthopedic Outpatient Setting.

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.

Fellowship and future career plans for orthopedic trainees: gender-based differences in influencing factors.

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.

A structured multimodal teaching approach enhancing musculoskeletal physical examination skills among undergraduate medical students.

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.

INTRAOPERATIVE EVALUATION AND LEVEL OF CONTAMINATION DURING TOTAL KNEE ARTHROPLASTY.

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.

Concurrent Research Around Meniscus: A Bibliometric Analysis and Review of the Top Fifty Cited Papers.

Purpose: The knowledge regarding meniscus has vastly evolved over the past few decades. The meniscus's intact, injured, and repaired status can affect other joint structures, i.e., ligaments, articular surfaces, and overall biomechanics of the knee joint. Due to available evidence's extensiveness, it is challenging to determine the most influential topics and the emerging trends in concurrent meniscus research. This study aims to identify the top fifty cited papers in meniscus research and concurrent knee issues and analyse their characteristics. Methods: A comprehensive search was conducted on the Thompson Reuters Web of Science database to prepare a list of top fifty cited articles that included original articles and review articles concerning meniscus. The included articles were analysed for the source journal, investigating institution, country of the corresponding author, year of publication, total citations, annual citation rate, and a qualitative review. Results: The search strategy resulted in 6768 original articles and 453 review articles. The top fifty cited articles were published from 1969 to 2014 and belonged to 14 journal sources. There were 43 original articles and seven review articles. The average citations per article were 417.4 and the average citations per paper per year were 22.6. Besides the meniscus, a general interest in the clinical assessment scores, anterior cruciate ligament, long-term osteoarthritis, and cartilage was observed. Conclusion: Most of the research concerning meniscus relates to the importance of meniscus preservation, the link between meniscus injuries and concomitant anterior cruciate ligament and chondral injuries, and its role in long-term gonarthrosis. The western countries have contributed the maximum to the top-cited evidence concerning meniscus. The meniscus repair and transplantation techniques have recently gained importance and need further research to qualify for the top-cited evidence.

Undergraduate Medical Students' Perceptions of an Online Audio-Visual-Based Module for Teaching Musculoskeletal Physical Examination Skills.

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.

Trends in the pursuit of multiple orthopedic surgery fellowships among orthopedic trainees in Saudi Arabia.

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.

Hamstring graft diameter above 7 mm has a lower risk of failure following anterior cruciate ligament reconstruction.

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.

Intraoperative evaluation and level of contamination during total knee arthroplasty / Avaliação e nível de contaminação intra-operatória durante a artroplastia total do joelho

Novel type of medial meniscus ramp lesion: a case report and surgical technique.

Meniscal ramp lesions have been reported in 9-24% of patients who underwent anterior cruciate ligament reconstruction (ACLR). We report a rare type of double medial meniscus ramp lesion in in a 26-year-old male soccer player who presented with persistent knee instability and an inability to return to sports after a successful ACLR due to unaddressed and untreated ramp lesions. To the best of our knowledge, this is the first reported case of a double ramp lesion, with tears occurring in two separate locations: one tear at the meniscosynovial junction and associated with meniscotibial ligament disruption; and a second, more posteriorly located at the meniscocapsular junction and associated with meniscocapsular attachment disruption. It was found to be very unstable upon arthroscopic assessment and was clinically associated with persistent knee instability even after ACLR, thus necessitating surgical repair to restore knee kinematics.

Confidence level, challenges, and obstacles faced by orthopedic residents in obtaining informed consent.

OBJECTIVES: The objective is to evaluate the opinions of orthopedic residents on current practices, experiences, training, confidence level, difficulties, and challenges faced when obtaining informed consent. DESIGN: This is a cross-sectional, multi-center, and questionnaire-based study. SETTING: The study was done in forty-four training centers across Saudi Arabia. PARTICIPANTS: In total, 313 orthopedic residents participated. MATERIAL AND METHODS: The web-based questionnaire examined the perceptions of residents regarding practices, experience, training, difficulties, and challenges surrounding the obtention of informed consent, as well as residents' confidence in obtaining informed consent for different orthopedic situations and eight common orthopedic procedures. RESULTS: Most residents were allowed to obtain consent independently for all emergency, trauma, primary, and revision cases at their institution (92.7%). Only 33.5% of the residents received formal training and teaching on obtaining informed consent, with 67.1% having believed that they needed more training. Only 4.2% of the residents routinely disclosed all essential information of informed consent to patients. Inadequate knowledge (86.3%) and communication barriers (84.7%) were the most reported difficulties. Generally, 77.3% of the residents described their confidence level in obtaining informed consent as good or adequate, and 33.9% were confident to discuss all key components of the informed consent. Residents' confidence level to independently obtain informed consent decreased with procedure complexity. Receiving formal training, senior level (postgraduate year (PGY) 4 and 5), and being frequently involved in obtaining informed consent correlated with increased confidence level. CONCLUSION: Many residents incompletely disclosed key information upon obtaining informed consent and reported lacking confidence in their ability to perform the procedure in their daily practices. To improve patient care and residents' performance and overcome these difficulties and challenges, institutions should develop effective strategies to standardize the informed consent process, provide formal training for obtaining informed consent, and provide supervision for residents during obtention of informed consent.

Prevalence of knee injuries among male college students in Riyadh, Kingdom of Saudi Arabia.

BACKGROUND: The knee is considered the most common injured joint between young sport participants. However, there is lack of proper prevalence estimation in our population. The purpose of this study was to identify the prevalence of knee injuries among male college students and to observe the demographic data associated with it. Our secondary objective was to evaluate the awareness and knowledge about these injuries. METHODS: This is a cross-sectional study. A survey was distributed to collect the data among male college students, King Saud University, Riyadh, Saudi Arabia. Out of 688 students who participated and completed the questionnaire, a total of 482 were considered valid and met the inclusion criteria. Data were analyzed using Statistical Package for Social Sciences (SPSS). RESULTS: The overall prevalence of knee injury was 23.2% (n = 112). Most of them injured during sport activities especially soccer and 68.7% involved in a non-contact mechanism of injury. Among those who went to a hospital mostly were diagnosed as contusion (31.4%) then as meniscus tear, ACL, and collateral ligament injury, respectively. Majority was treated conservatively and only 10.7% needed surgery surprisingly. There was no statistically significant difference between those who are injured and whether they were warmed up and stretched or not (P = 0.619). Low level of knowledge about knee injuries was noticed among the participants 57.7%. CONCLUSION: Our study has highlighted the high prevalence of knee injuries and the need to raise the level of awareness and knowledge about these injuries in our population. Soccer was the most common sport associated with knee injuries; most of these injuries were treated conservatively.

Associations of self-esteem with body mass index and body image among Saudi college-age females.

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.

Hamstring autografts are associated with a high rate of contamination in anterior cruciate ligament reconstruction.

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.

Late reconstruction of the patellar tendon in rheumatoid arthritis using bone-patellar tendon-bone allograft.

INTRODUCTION: chronic patellar tendon rupture is rare and its incidence and prevalence are unknown. Furthermore, the data about late reconstruction of the patellar tendon in rheumatoid arthritis is limited. Such condition, if not managed properly, can substantially affect the patient's activities of daily living. CASE PRESENTATION: We report a case of chronic patellar tendon rupture in a 49 years old lady who has been suffering from rheumatoid arthritis for over 20 years. She presented with an inability to extend the right knee which started suddenly a year and a half ago without any history of trauma. She underwent reconstruction of the patellar tendon using a massive BTB allograft. Three years after surgery, the patient had an active range of motion between -20 and 120° and was walking normally without any external support. DISCUSSION: When the primary repair of the patellar tendon is not possible, it is necessary to either repair with autologous augmentation or use a graft to reconstruct the tendon. We believe autografts may not be suitable in the presence of rheumatoid arthritis since the disease is associated with excessive levels of collagenase that could contribute to the degeneration of the tendons. CONCLUSION: Late patellar tendon reconstruction in rheumatoid arthritis is a challenging procedure, and we believe it is best performed using an allograft to achieve the desired outcome.
