Intra-Articular Analgesia and Steroid Reduce Pain Sensitivity in Knee OA Patients: An Interventional Cohort Study
Figure 2
Mean computer-controlled PPTs (95% CI, at tests 1, 2, and 3, at test 4) on the infrapatellar fat pad (a), vastus lateralis (b), and tibialis anterior (c) before (baseline tests 1 and 2), immediately after (test 3), and two weeks after (test 4) the injection of lidocaine and glucocorticosteroid. PPTs were significantly increased at all three test sites compared with baseline 2 (test 2) () immediately after (test 3) and further significantly increased two weeks after (test 4) the injection compared to immediately after the injection (test 3) on the infrapatellar fat pad () and tibialis anterior (), but not at vastus lateralis ().
