肩关节镜患者术后发生慢性疼痛的危险因素OA

Objective To explore the characteristics of postoperative pain after shoulder arthroscopy and its associated risk factors for chronicity.Methods The data of patients who underwent orthopedic shoulder arthroscopic surgery at the First Medical Cen-ter of PLA General Hospital from January to December 2021 were retrospectively analyzed.General patient data and surgery-related in-formation were collected,and resting pain was assessed preoperatively,1 day and 3 days after surgery,and 3 months after surgery u-sing the Numerical Pain Score(NRS).Surgery-induced pain that was secondary to acute postoperative pain and lasted longer than 3 months was defined as postoperative chronic pain.Logistic Regression was used to analyze the correlations between age,gender,body mass index(BMI),preoperative diagnosis,duration of disease,surgical method,degree of preoperative and 3-day resting pain,num-ber of shoulder structures involved in the procedure,and number of surgeries and factors and postoperative chronic pain.Results A total of 300 patients(170 males and 130 females)were included in this study.There were no statistically significant differences in pre-operative resting pain among different groups at postoperative days 1 and 3,or at 3 months(F=1.609,P=0.194).The NRS score at 3 months after surgery was significantly lower than that before surgery,1 day,and 3 days after surgery(P<0.05).Age≥50 years,SLAP injury,biceps long head muscle resection or repair surgery,3-day postoperative resting pain≥5 points,number of surgeries≥2,and duration of disease≥12 months were significantly associated with the occurrence of postoperative chronic pain(P<0.05).Conclusions Age≥50 years,SLAP injury,biceps long head muscle resection or repair surgery,postoperative resting pain degree at 3 days,number of surgeries and duration of disease are associated risk factors for postoperative chronic pain.
