Fatores preditores de qualidade de vida após reconstrução do ligamento cruzado anterior

Abstract

The present study was conducted to verify the predictive factors of Quality of Life (QoL) after Anterior Cruciate Ligament Reconstruction (ACLR). In the single open prospective cohort study we aimed to understand if body structure (graft type, injury according to dominance and concomitant injury), body function (self-reported function scales, muscle strength symmetry index, Agonist/antagonist ratio and postural stability), activity and participation (hop tests and self-reported function scales), personal factors (gender, age, weight, height, body mass index, postoperative time and psychological factors) and environmental factors (contact injury) can predict the QoL in individuals undergoing ACLR and followed for two years after the initial evaluation. In total, 85 participants with an average of 11 months of ACLR were assessment (August 2018 to July 2019) and they were followed up from July 2020 to December 2021. They filled out an online form at follow-up. At baseline and follow-up, QoL was assessed using ACL- QoL; knee functional status, using International Knee Documentation Committee Subjective Knee (IKDC) and Global Rating Scale (GRS); psychological readiness, using Anterior Cruciate Ligament Return to Sport after Injury Scale (ACL-RSI); kinesiophobia, using Tampa Scale for Kinesiophobia (TSK-17); knee strength, using isokinetic dynamometer (Biodex Multi-Joint System Pro Biodex Medical System, Shirley, New York); performance, using single-leg hop tests; and postural stability, using Biodex Balance System. Multiple linear regression analyses were performed to verify the predictors of the ACL-QoL score at follow-up. Contact injury, higher hamstring symmetry index predicted better ACL-QOL score. Non-dominant limb injury, higher level of kinesiophobia, longer postoperative time at baseline and higher agonist/antagonist ratio predicted worse ACL-QOL score. Kinesiophobia, muscle strength and injury-related factors were predictors of QoL in patients with ACLR and followed up two to two and a half years after the return to sport assessment. Understanding the factors that predict QoL in patients undergoing ACLR may enable the implementation of therapeutic strategies that optimize clinical results in this population. Therapeutic strategies that optimize clinical results in this population can be implemented.
