Publication Knee Iliotibial Band Z-Plasty Lengthening and Bursectomy Technique(2022) Vaisman, Alex; Guiloff, Rodrigo; Andreani, DomingoMultiple surgical techniques have been described to treat refractory iliotibial band syndrome. However, there is lacking evidence demonstrating superiority of one technique over the other and limited audiovisual resources. Most surgical procedures aim to release the iliotibial band; nevertheless, few focus on reducing concomitant inflammation. The present article illustrates a Z-plasty lengthening technique associated with local bursectomy for treating iliotibial band syndrome refractory to conservative treatment.Publication Over 50% of self-reported burnout among Latin American orthopaedic surgeons: A cross-sectional survey on prevalence and risk factors(2023) Vaisman, Alex; Guiloff, Rodrigo; Contreras, Martín; Casas, Juan; Calvo, Rafael; Figueroa, DavidObjective: Assess the prevalence of self-reported burnout and identify risk and protective factors based on demographic and life quality aspects, among Latin American orthopaedic surgeons. Methods: This study employed a cross-sectional analytical design. An original design survey was developed using multiple-choice and Likert-scale questions to gather self-reported burnout, demographic, work-related, social, personal, and mood-related data. The survey was electronically distributed to the Chilean Orthopaedic Surgery Society and the Latin American Society of Arthroscopy, Knee Surgery, and Sports Medicine members. Statistical analysis included Chi-square and Fisher's exact tests to determine associations between self-reported burnout and other variables. Subsequently, a multivariate logistic regression was carried out to identify key risk and protective factors (p < 0.05). Results: The survey's response rate was 20 % (n = 358) out of the 1779 invitations that were sent. The most representative age range was 41-60 years (50 %) and 94 % were men. Of those surveyed, 50 % reported a burnout episode more than once per year, 60 % depersonalization when treating patients at least yearly, 13 % anhedonia, 11 % a depressive mood more than half of the month or almost every day, and 61 % weariness at the end of a working day. Burnout was statistically associated with age under 40 years old (p = 0.012), fewer years as a specialist (p = 0.037), fear of lawsuits (p < 0.001), a non-healthy diet (p = 0.003), non-doing recreational activities (p = 0.004), depersonalization when treating their patients (p < 0.001), weariness (p < 0.001), anhedonia (p < 0.001), depressive mood (p < 0.001), and career dissatisfaction (p < 0.001). The logistic regression demonstrated that fear of lawsuits (p < 0.001), weariness at the end of a workday (p = 0.016), and anhedonia (p = 0.019) were those variables with stronger direct associations with self-reported burnout. A healthy diet was the strongest protective variable (p < 0.001). Conclusion: Over 50 % of the Latin American orthopaedic surgeons who participated in the survey reported experiencing burnout episodes more than once a year, along with depersonalization when treating their patients at least once a year. Additionally, nearly 10 % of respondents experienced weekly depressive symptoms. Among the noteworthy risk factors for self-reported burnout were fear of lawsuits, weariness at the end of the workday, and anhedonia. Conversely, maintaining a healthy diet emerged as the most potent protective factorPublication Virtual reality training is associated with high satisfaction and self-perceived surgical confidence in anterior cruciate ligament reconstruction: Experience from an orthopedic residency pilot study(2026) Guiloff, Rodrigo; Pino, Ernesto; Armijo-Rivera, Soledad; Cabrolier, Jorge; Schulmeyer, Juan; Radkievich, Ruben; Vaisman, Alex; Rafael, Calvo; Figueroa, DavidIntroduction/objective: Virtual reality (VR) is increasingly used in surgical education by enabling risk-free, immersive, and independent training. As orthopedic surgery residency programs increasingly integrate VR-based simulation, evidence regarding trainee satisfaction and self-perceived confidence remains scarce. This study aims to evaluate orthopedic surgery residents' satisfaction and self-perceived confidence following VR-based simulation training (VRT) in anterior cruciate ligament reconstruction (ACLR). The hypothesis is that VRT would result in high satisfaction and improve confidence in performing the procedure. Methods: A cross-sectional pilot study was conducted on 12 orthopedic surgery residents (4 per postgraduate year) from a three-year residency program. Residents with prior VR-based ACLR simulation experience were excluded. Each participant completed two VRT sessions using PrecisionOS software on the Oculus Quest 2 headset, practicing the inside-out ACLR technique. Pre- and post-training assessments included a validated five-point Likert scale and the net promoter score (NPS) to measure satisfaction and self-perceived confidence. Results: Eleven residents (91.7%) completed the study. Overall satisfaction with VRT was high, with most participants rating the experience as "agree" or "strongly agree" across all learning dimensions. The second session showed higher median satisfaction scores in five of six items. Participants valued VR training to improve procedural understanding, facilitate content application, and reinforce skills through immersive, tutor-independent learning. Overall, all sections achieved positive NPS values exceeding 40 (41-73), highlighting that VR training was an engaging way to learn. Third-year residents reported the greatest improvement regarding self-perceived confidence in executing the procedure, particularly to perform as the primary surgeon. First- and second-year residents showed increased confidence in assisting the procedure. Conclusion: This pilot study suggests that VR-based ACLR training is well accepted by orthopedic surgery residents and provides a highly satisfactory and immersive learning experience. Residents reported improved understanding of procedural steps and increased self-perceived confidence, with senior residents benefiting most in relation to the primary surgeon role and junior residents reporting greater confidence in assisting in the procedure. These findings support the feasibility and acceptability of VR simulation as a self-directed educational tool within orthopedic residency training programs
