Publication Age influences the efficacy of osteochondral autograft transfer: Promising results for patients under 40(2024) Figueroa, Francisco; Figueroa, David; Calvo, Rafael; Stocker, Esteban; Itriago, Minerva; Nuñez, MarilauraBackground: Previous research using osteochondral autograft transfer (OAT) has shown poorer outcomes with increasing patient age. The aim of this article is to evaluate a cohort of patients that received an OAT and to correlate their clinical results with their age at procedure. Methods: Patients that underwent an OAT to treat an osteochondral (OC) lesion with a minimum 24-month follow-up were included. Patients were categorized into two groups based on their age at procedure (<40 years and ≥40 years). Postoperatively, each patient completed the Knee injury and Osteoarthritis Outcome Score (KOOS), International Knee Documentation Committee (IKDC), and Lysholm scales. Results: 51 patients were included (35<40 years, 16≥40 years). Mean follow-up was 4.2 years (2-7). For patients<40 years, IKDC averaged 80.8 (SD 15.9) versus 71.2 (SD 19.4) in ≥40 years (p=0.03). For patients <40 years, Lysholm averaged 85.9 (SD 10.8) versus 77.0 (SD 21.6) in ≥40 years (p=0.02). For patients<40 years, KOOS averaged 78.3 (SD 11.8) versus 68.9 (SD 18.5) in ≥40 years (p=0.01). There was a 100% sensibility in identifying all the patients with a poor IKDC and Lysholm from 34 years old (AUC 0.76 and 0.8). Conclusions: OAT has better outcomes in patients younger than 40 years compared to patients older than 40 years. Based on the prognostic capacity of age, the ideal candidate for an OAT is a patient younger than 34 years old.Publication 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, SergioAntecedentes 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.Publication 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, EstebanPrior 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.
