Validación y correlación ultrasonido diagnóstico lesiones de rodilla. Pacientes adultos con trauma deportivo. Hospital José Carrasco Arteaga. Cuenca 2019

Abstract

a. Background: Sports activities have increased as a lifestyle improvement, but also sports trauma injuries, which could be in any joint, the knee being the most frequent target, so an early diagnosis is necessary to minimize complications and disabilities. b. Objective: the validity and correlation of ultrasound in the diagnosis of knee injuries in adult patients with sports trauma who attended the José Carrasco Arteaga Hospital was determined. Cuenca 2019. c. Methods: was a validation study of diagnostic tests determining the effectiveness and correlation of ultrasound compared with nuclear magnetic resonance, during January 2019 to August 2020. The sample was representative, based on sensitivity of 98%, specificity 88%, prevalence of knee injuries 45.5 %, accuracy 5%, confidence level 95%. A questionnaire validated in a pilot plan was used and the analysis was performed using EPI software v.4.1, Excel, SPSS v 2.1. d. Expected results: Lesions are more frequent between 36 and 58 years old, predominantly males. Joint effusion (92,4%), intracapsular and extracapsular ligament injuries (23%), bursitis and meniscopathies (19%) were identified by ultrasound. By magnetic resonance, they were intra and extracapsular ligament injuries (31,7%), joint effusion (22,9%) and meniscopathy (22,1%). Ultrasound showed sensitivity for tendinopathies (87,32%), extracapsular injury (87,9%) and joint effusion (95,36%); specificity for tendinopathy (93,6%), intracapsular lesion (94,25%). Positive predictive value for meniscopathy (94,17%), joint effusion (91,43%) and tendinopathy (90,51%) and negative predictive value for tendinopathy (91,35%) and extracapsular injuries (84,68%)
