In this study, each knee was marked with a grid of eight squares, and 40 lines of micro-focused ultrasound were applied to each square, or 320 lines to each knee. The Abstract (line 6, page 225) and the Methods (line 5, column 2, page 226) incorrectly state that 480 lines of micro-focused ultrasound were applied to each knee.
