The Neuromatrix Theory of Pain and Transactional Theory of Stress and Coping: Improving Understanding of Pain Catastrophizing in Individuals With ACL Reconstruction and Knee Osteoarthritis.

Individuals with anterior cruciate ligament reconstruction and early knee osteoarthritis symptoms commonly exhibit psychological impairments, such as pain catastrophizing. Pain catastrophizing is a negative cognitive–affective response to anticipated or actual pain and has been linked to greater pain intensity and decreased function in this population. However, an examination of the neuromatrix theory of pain and the transactional theory of stress and coping may help to explain the development and consequences of pain catastrophizing in individuals with anterior cruciate ligament reconstruction and early knee osteoarthritis symptoms. Exploration of these theoretical models will help clinicians better understand the impact of pain catastrophizing on post-injury outcomes, as well as help to identify intervention strategies to address maladaptive psychological responses and improve outcomes for individuals with anterior cruciate ligament reconstruction and early knee osteoarthritis symptoms.
