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 Cross-cultural adaptation and validation of the KOOS, JR questionnaire for assessing knee osteoarthritis in Spanish-speaking patients(2023) Guiloff, Rodrigo; Iñiguez, Magaly; Prado, Tomás; Figueroa, Francisco; Olavarría, Nicolás; Carrasco, Eduardo; Ergas, Enrique; Salgado, Martín; Lyman, StephenPurpose The present study aims to translate, adapt and validate a Spanish version of the Knee Injury and OsteoarthritisOutcome Score, Joint Replacement (KOOS, JR), including a reliability and validity analysis in patients with knee osteoar-thritis (OA).Methods This study conducted a prospective validation study following the six stages of the “Guidelines for the Process ofCross-Cultural Adaptation of Self-Report Measures”. Psychometric testing was conducted in patients with knee osteoarthritis.Subjects answered the Spanish KOOS, JR (S-KOOS, JR) and a validated Spanish Oxford Knee Score (S-OKS). Retest wasconducted at 10 days. Acceptability, floor and ceiling effect, internal consistency (Cronbach’s α), reproducibility (mixed-effect model coefficient [MEMC]) and construct validity (Spearman’s correlation; p = 0.05) were assessed.Results Forty-one patients (mean age: 65.6 ± 5.39; 48.8% female) participated in the study. All patients (100%) answeredboth scores during the first assessment and 38 (92.7%) during the second assessment. All patient-reported outcomes measureswere answered completely (100%). The S-KOOS, JR resulted in 100% acceptability when answered. There were no ceilingor floor effects detected. The Cronbach’s α for the S-KOOS, JR was 0.927 and its MEMC was 0.852 (CI 95% 0.636–1.078).The Spearman’s correlation between the S-KOOS, JR and the S-OKS was 0.711 (CI 0.345–0.608; p < 0.001) and 0.870 (CI0.444–0.651; p < 0.001) for the first and second assessments, respectively.Conclusion The S-KOOS, JR has very high internal consistency and reproducibility, with a high correlation with the S-OKS;it is a reliable and valid instrument for characterising Spanish-speaking patients suffering from knee OA.Level of evidence IV.
