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 ( ).
