Right now, five scenes were playing simultaneously in Yan Feifan's mind, replaying footage of Dr. Chen Yu treating different patients' injuries at high speed.
In all five scenes, Mrs. Chen's expression was focused, but there was nothing particularly remarkable or unique about the way she handled the procedures.
But Yan Feifan knew that was only on the surface.
Tendons heal slowly and are under high tension. This means the severed ends must be sutured together perfectly, leaving no gaps or misalignment.
Furthermore, the contact surfaces of the suture must not be wrinkled. Wrinkles could lead to keloid scarring, which might result in chronic pain.
For these reasons, the technical demands of tendon suturing are exceptionally high.
There was also the fact that a sutured tendon needs to be immobilized in a cast for at least two to three weeks, preventing external forces from disrupting the healing process.
Adhesions could easily form during this recovery period.
