<imgsrc=”” border=”0″ align=”left” alt=”image”>The study aimed to explore the prognostic value of fear-avoidance beliefs (FABs) on postoperative pain and back-specific function for patients with lumbar degenerative disk disease (LDDD). FABs have been proven to be a predictorof pain and disability for patients with low back pain. However, whether FABs are a predictor of surgical outcomes for LDDD is a matter of debate. PubMed, Cochrane library, EMBASE, and EBSCO were searched for eligible cohort studies or secondary analyses of randomized controlled trials. Fixed-effect meta-analysis models were used to estimate odds ratios (OR) because of absent or low heterogeneity (I² 12 months). Clinicians are advised to initiate targeted interventions for patients with FABs at different stages after surgery. Due to the limited number and low quality of included studies, the results of this meta-analysis should be interpreted with caution.
