COMPLICATIONS
Shoulder surgery involves multiple muscles and ligaments. Patients undergoing ARCR experience more pain after surgery than those who undergo other shoulder arthroscopy procedures.The concept of perioperative ERAS was introduced by Danish surgeon Henrik Kehlet in 1990.Nerve block techniques modify the generation of responses to stress by modulating or inhibiting the transmission of noxious afferent signals during surgery.The results of the current study show that group A had the longest LOS whereas group C had the shortest LOS, which is consistent with previous findings.Postoperative pain induces the stress response in the body and delays postoperative recovery, thus affecting functional recovery. However, Tirefort et alThe CMS score was adopted by the European Society for Surgery of the Shoulder and the Elbow as a standardized scale for the assessment of shoulder function and is now used worldwide.Shoulder swelling and stiffness are common complications in the early postoperative periodPrevention of shoulder stiffness requires early and standardized rehabilitation.This study has some limitations. Firstly, it had a small sample size and was conducted at a single center, which may have introduced bias. Further studies should be conducted at multiple centers in order to facilitate more scientific and accurate conclusions. Furthermore, the length of the follow-up period was short; the longest follow-up period was only 3 months. In the future, the follow-up period should be extended to facilitate observation of long-term efficacy.
