ABSTRACT
Quantitative Sensory Testing (QST) can be useful to identify high-risk patients for the development of chronic postsurgical pain (CPSP). This systematic review aims to assess if presurgical sensory sensitivity measured using QST is associated with acute and CPSP after total joint arthroplasty.A systematic search was performed in Sep/2020 in PubMed, EMBASE, Web of Science and Scopus, using terms related to total joint arthroplasty and QST. Prospective studies were included if they reported an association between presurgical QST and postsurgical pain in adults with osteoarthritis undergoing primary unilateral total joint arthroplasty.From 2994 identified studies, 18 met the inclusion criteria (1869 patients). Total knee arthroplasty was the most common surgery (16 studies) and pressure pain threshold (PPT) was the most common test (11 studies), followed by dynamic measures (9 studies). Postsurgical pain was assessed at acute (5 studies), subacute (2 studies) and chronic (13 studies) time points. Risk of bias was assessed using the Quality in Prognosis Studies Tool, and evaluated as low-to-moderate in most domains. Fourteen studies reported at least one statistically significant association between QST and pain (acute: 4 studies, subacute: 1 study, chronic: 9 studies). PPT was associated with postsurgical pain in 6 studies (out of 11, 55%), heat pain threshold in 2 (out of 6, 33%), conditioned pain modulation in 1 (out of 6, 17%) and temporal summation of pain in 5 (out of 8, 63%). The predictive role of presurgical QST for post-arthroplasty pain remains unclear, mainly due to heterogeneous methodologies and inconsistent results.
