- Abstract
Introduction. Patellar tendinopathy (PT), common in athletes, poses a challenging diagnosis. Thermal assessment by infrared thermography (IRT) and grey-level co-occurrence matrix (GLCM) analysis of infrared images could help in the identification and characterisation of this pathology. Objectives. To evaluate thermal and textural changes in athletes with unilateral PT versus asymptomatic athletes, and to analyse their correlation with symptomatology and functionality. Methods. In this cross-sectional study we worked with a group of athletes with unilateral PT (n=27) and a group of asymptomatic athletes (n=27). Infrared images of the patellar tendons of both groups were recorded and the symptomatology and functionality of the knees were quantified using the VISA-P questionnaire. Thermal symmetry between patellar tendons and GLCM of the infrared images was analysed and finally correlated with the results of the VISA-P questionnaire. Results. As expected, the thermal difference between knees in the PT group was larger than in the control group, with an effect size of 0.79. No correlation was observed between temperature and the VISA-P scale (rxy= -0.162, p= 0.242, R2= 0.03). In relation to GLCM, the PT group showed a higher textural correlation (effect size 0.85) and a lower homogeneity (effect size of 0.47) than the control group. A significant correlation was only observed for the textural correlation in inverse and weak correlation (rho= -0.276, p= 0.013, R2= 0.18). Conclusions. The analysis of thermal symmetry and GLCM on thermal images of patellar tendons could be used as an aid in the diagnosis and clinical follow-up of patients with TR, despite not having found a correlation with knee pain and functionality measured with VISA-P scale.
