Abstract

CLINICAL, FUNCTIONAL AND RADIOLOGICAL FACTORS RELATED TO KNEE PAIN IN GONARTHROSIS."Background. Gonarthrosis is a progressive and degenerative disease of the knee joint, which is associated with chronic pain, progressive loss of functionality, leading to a decrease in quality of life and limitation in the activities of daily living.Objective. Identify the correlation between the clinical, functional, and radiological factors associated with knee pain in patients with gonarthrosis.Material and methods. An observational, descriptive, prospective, and transversal study was conducted including patients who fulfilled the inclusion criteria at Physical and Rehabilitation Medicine Unity No.1 with gonarthrosis to identify the clinical, functional, and radiological factors associated with knee pain in patients with gonarthrosis.Results. 24 patients were recruited, 75% women (n=18) and 25% male (n=6), the mean age was 56 years old (SD=8.70), mean evolution time was 12.9 months (SD=27.8). Most affected knee was the left side with a 45.8% (n=11). Knee severity accordingly with Kellgren-Lawrence system for grade 1 was, 33.3% (n= 8), grade 2, 50% (n=12), grade 3, 12.5% (n=3) and grade 4, 4.2% (n=1). The pain presentation percentage according to Visual Analog Scale (VAS) for mild pain was, 8.3% (n=2), moderate pain, 33.3% (n=8), and severe pain, 58.3% (n=14). The mean punctuation of the WOMAC index was 51.4 (DE=20.3). The Time Up and Go Test (TUGT) percentage for independent mobility was,16.7% (n=4), mostly independent 70.8% (n=17) and reduced mobility, 12.5% (n=3).A significative correlation was found between pain according to VAS and evolution time (p=0.039), TUGT (p= 0.018) and WOMAC index (p=0.009). Conclusion.Evolution time, performance in the TUGT and WOMAC index scoring are related with presence of knee pain in patients with gonarthrosis.
