Comparación entre el grado de dolor y presencia de limitación funcional con el grado de severidad según la escala radiológica de Kellgren y Lawrence en los pacientes con gonartrosis intervenidos de artroplastia total de rodilla en el Hospital Teodoro Maldonado Carbo desde enero de 2019 a diciembre de 2020.

Abstract

Introduction: Gonarthrosis or knee osteoarthritis is the most common type of osteoarthritis in the adult population and causes degenerative, muscular and biomechanical changes in the joint causing pain, stiffness, crepitus and decreased functional status of the individual. Objective: To compare the degree of pain and presence of functional limitation with the degree of severity according to the Kellgren and Lawrence radiological scale in patients with gonarthrosis who underwent total knee arthroplasty at the Teodoro Maldonado Carbo Hospital from January 2019 to December 2020. Materials and methods: Observational, retrospective, cross-sectional and analytical study. We obtained the data through the review of medical records of a population of 210 patients with gonarthrosis. Results: The degree of pain was moderate in 113 cases (53.8%) and severe in 94 (44.8%), while 194 patients presented functional limitation (92.4%). The severity of gonarthrosis according to the Kellgren and Lawrence radiological scale was grade IV in 160 (76.2%), III in 44 (21%) and II in 6 patients (2.9%). An association between the degree of pain and the degree of severity of gonarthrosis was confirmed (p= 0.001), in the same way, between the presence of functional limitation and degree of severity of gonarthrosis (p= 0.009). Conclusions: Severe knee pain was associated with a moderate to severe degree (grades III and IV) according to the Kellgren and Lawrence radiological scale. Likewise, patients scheduled to undergo total knee arthroplasty who presented functional limitation also showed a higher degree (IV) of radiographic severity.
