OBJECTIVE: To study the variation of skin temperature values (deltaT) on operative site, of reactive C protein (RCP) and of hemosedimentation speed (HSS) in patients submitted to primary knee total arthroplasty (KTA), in an attempt to establish a correlation among its curves over time. MATERIALS AND METHODS: This prospective clinical study evaluated 29 patients followed up during 12 weeks, with measurements of skin temperature in both knees and RCP and HSS serum dosages. RESULTS: After comparing the variables tested (deltaT, RCP and HSS), no statistical correlation was observed for both the Pearson’s test (parametric test) and the Spearman’s test (non-parametric test) among variables. Skin temperature variation follows a different pattern from that observed both for RCP and for HSS, with no correlation among curves. A standard curve was established for the three variables, and a statistically significant reduction was seen in RCP and HSS values from pre- to post-operative period. CONCLUSION: No correlation was observed between skin temperature and HSS and RCP levels in patients submitted to uncomplicated primary KTA.
