Resumen INTRODUCCIÓN: La gonartrosis es una causa frecuente de dolor crónico y discapacidad en adultos mayores. Los factores psicosociales, como el estrés percibido, pueden influir en la limitación funcional y la evolución clínica de la enfermedad. OBJETIVO: Determinar la relación entre el nivel de estrés percibido y el grado de limitación funcional en pacientes con gonartrosis adscritos a una unidad de medicina familiar. MATERIAL Y MÉTODOS: Estudio observacional, analítico y transversal en pacientes con gonartrosis atendidos en la UMF No. 92 del IMSS. Se aplicó la escala de Estrés Percibido PSS-14 y el índice algofuncional de Lequesne. Se utilizó estadística descriptiva e inferencial mediante chi cuadrada de Pearson. RESULTADOS: Se identificó una asociación estadísticamente significativa entre niveles elevados de estrés percibido y mayor grado de limitación funcional (χ²=7.703; p=0.011).CONCLUSIONES: El estrés percibido se asocia con mayor limitación funcional en pacientes con gonartrosis, lo que refuerza la necesidad de un abordaje integral en el primer nivel de atención. Abstract INTRODUCTION: Gonarthrosis is a common cause of chronic pain and disability in older adults. Psychosocial factors, such as perceived stress, may influence functional limitation and the clinical course of the disease. OBJECTIVE: To determine the relationship between the level of perceived stress and the degree of functional limitation in patients with gonarthrosis affiliated with a family medicine unit. MATERIALS AND METHODS: An observational, analytical, cross-sectional study was conducted in patients with gonarthrosis treated at Family Medicine Unit No. 92 of the Mexican Social Security Institute (IMSS). The Perceived Stress Scale (PSS-14) and the Lequesne algofunctional index were applied. Descriptive and inferential statistical analyses were performed using Pearson’s chi-square test. RESULTS: A statistically significant association was identified between high levels of perceived stress and greater functional limitation (χ² = 7.703; p = 0.011). CONCLUSIONS: Perceived stress is associated with greater functional limitation in patients with gonarthrosis, reinforcing the need for a comprehensive approach at the primary care level.
