Intra-Articular Analgesia and Steroid Reduce Pain Sensitivity in Knee OA Patients: An Interventional Cohort Study
Figure 3
Mean manual PPTs (95% CI, at tests 1, 2, and 3; at test 4) at the knee (filled circles) and the contralateral arm (control site—open triangles) before (baseline tests 1 and 2), immediately after (test 3), and two weeks after (test 4) the injection of lidocaine and glucocorticosteroid. PPT was significantly increased at the knee immediately after (test 3) () and two weeks after (test 4) (), but not at the control site (), compared with baseline 2 (test 2).
