Tendon adhesions, once a therapeutic challenge, have been treated more satisfactorily, but the correct approach must be mastered, otherwise the treatment outcome will be difficult to ascertain. The current systematic treatment method includes in place preoperative preparation, mature intraoperative muscle-tendon separation techniques and postoperative professional functional training. Professor Chang Li has applied high-precision non-invasive surgical operation techniques to tendon surgery on the premise of perfecting the current systematic treatment methods, and explored the characteristics of high-precision non-invasive surgical operation techniques of less bleeding, anti-swelling, anti-pain, anti-adhesion, and fast recovery, together with perfect preoperative preparation and well-designed postoperative functional training program, which has raised the postoperative effect of tendon adhesions to a new standard and made the flexion and extension of fingers The postoperative results of tendon adhesions were raised to a new standard, resulting in greater and more flexible finger flexion and extension, and satisfactory and positive treatment results were achieved.
