Abstract: OBJECTIVE:To investigate whether pre-operative Quantitative Sensory Testing (QST) can identify patients who experience persistent post-operative knee pain following Total Knee Replacement (TKR). DATA SOURCES:PubMed, EMBASE, CINAHL, EBSCO and grey literature. STUDY SELECTION:1056 studies were retrieved. The title and abstracts were screened by two independent reviewers, of which 45 were retrieved for full text analysis and 16 studies were included. Studies of any design were included if they recruited adults who underwent TKR; completed any component of the German Research Network on Neuropathic Pain QST or conditioned pain modulation testing preoperatively and assessed post-surgical joint pain using a self-reported outcome measure at a minimum of three months post TKR. DATA EXTRACTION:Data was independently extracted by two researchers. Disagreements were resolved through consensus. The extracted data was recorded in a predefined spreadsheet. Domains included demographic data, type and site of QST, pain outcome measure, follow up duration, statistical methods and associative data. Two independent reviewers assessed the quality of studies using Quality in Prognosis risk of bias tool and the certainty of evidence using the GRADE framework. DATA SYNTHESIS:Sixteen cohort studies met the eligibility criteria (n = 2051 patients). Data was analysed narratively because of the heterogeneity across the QST procedures (mechanical and thermal detection and pain thresholds, conditioned pain modulation and temporal summation of pain), measures of reporting pain (Western Ontario and McMaster Universities Osteoarthritis Index, visual analogue scale and numeric pain rating score) and follow up time points (3 to 18 months). CONCLUSIONS:Due to the heterogeneity and low-moderate quality studies included, it remains unclear whether QST can identify patients who are likely to experience persistent postoperative joint pain following TKR.
