    4 Domain Sports PROM en español: adaptación transcultural en la población chilena y análisis de confiabilidad
    (2024) Figueroa, David; Guiloff, Rodrigo; Figueroa, Francisco; Stocker, Esteban; Rocha, Sergio
    Antecedentes y objetivo: Las medidas de resultado reportadas por el paciente (PROM) son herramientas de interés creciente en la población deportiva. El propósito de este estudio fue realizar la adaptación transcultural y análisis de confiabilidad del 4-Domain Sports Patient-Reported Outcome Measure (4DSP) al español. Métodos: Se ejecutó un protocolo de adaptación transcultural en seis etapas para obtener la versión en español del 4DSP (S-4DSP). Posteriormente, se aplicó el cuestionario a una población de 108 deportistas posoperados de reconstrucción de ligamento cruzado anterior (RLCA). Se aplicó nuevamente el cuestionario luego de 30 días. Se evaluó la aceptabilidad, efecto piso y techo, consistencia interna (alfa de Cronbach) y reproducibilidad (correlación intraclase). Resultados: La S-4DSP fue respondida completamente por 108 participantes (edad media 34 ± 10,75, 26% mujeres) alcanzando una aceptabilidad de 100%. No se detectó efecto piso. El análisis estadístico entregó un alfa de Cronbach global para el cuestionario de 0,65, y desagregado por dominios de 0,88, 0,72, 0,27, 0,68 para el primer, segundo, tercer y cuarto dominio, respectivamente. El estudio de correlación intraclase alcanzó un máximo de 0,94 y un mínimo de 0,48 en la primera y quinta preguntas, respectivamente. Conclusión:El S-4DSP es una herramienta confiable y útil para evaluar deportistas de habla hispana posterior a una RLCA. Abstract Background: Patient-Reported Outcome Measures (PROMs) are tools of increasing interest in the sports population. The purpose of this study was to perform the cross-cultural adaptation and reliability analysis of the 4 Domain Sports Patient-Reported Outcome Measure (4 DSP) into Spanish. Methods: A six-stage cross-cultural adaptation protocol was executed to obtain the Spanish version of the 4 DSP (S-4DSP). Subsequently, the questionnaire was administered to a population of 108 postoperative athletes with ACL (Anterior Cruciate Ligament) injuries. The questionnaire was administered again after 30 days. Acceptability, floor and ceiling effects, internal consistency (Cronbach's alpha), and reproducibility (Intraclass Correlation) were evaluated. Results: The S-4DSP was fully completed by 108 participants (mean age 34 ± 10.75, 26% women), achieving 100% acceptability. No floor effect was detected. The statistical analysis yielded a global Cronbach's alpha for the questionnaire of 0.65, and domain-specific alphas of 0.88, 0.72, 0.27, and 0.68 for the first, second, third, and fourth domains, respectively. The Intraclass Correlation test reached a maximum of 0.94 and a minimum of 0.48 for the first and fifth questions, respectively. Conclusions: The S-4DSP is a reliable and useful tool for evaluating Spanish-speaking athletes after ACL reconstruction.

    Specific considerations in female patients with patellar instability: current concepts
    (Figueroa F, Guiloff R, Bolton S, Figueroa D, Tapasvi S, Stocker E. Specific considerations in female patients with patellar instability: current concepts. J ISAKOS. 2024 Jun;9(3):457-463. doi: 10.1016/j.jisako.2024.03.014, 2024) Figueroa, Francisco; Guiloff, Rodrigo; Bolton, Sarah; Figueroa, David; Tapasvi, Sachin; Stocker, Esteban
    Prior literature suggests that patellofemoral instability (PFI) is significantly more prevalent in women than in men. This higher prevalence is commonly attributed to anatomical differences between sexes, particularly with patellofemoral alignment. These differences encompass a higher rate of trochlear dysplasia (TD), patella alta, an increased Q angle, and soft tissue imbalances. In recent years, worse outcomes have been reported in female patients after patellofemoral stabilization surgery using medial patellofemoral ligament reconstruction (MPFLr) alone or in combination with a tibial tubercle osteotomy (TTO), for this reason an "à la carte" plan (addressing the individuals anatomical risk factors) could be more appropriate for female patients.
