“…No change in the expression of Col 1 and Col 3, Col fiber structure, and arrangement were seen. In another long-term study, one longitudinal incision significantly increased tendon cross-sectional area from day 0 (16 ± 2 mm 2 ) to day 84 (26 ± 6 mm 2 ) and peaked at day 21 (36 ± 12 mm 2 ) [ 155 ]. Ultrasonography showed that tendon lesions increased from 21increased form 21 days–84 days and peaked at 42 days.…”
