To explore the effects of Honghua Huayu Decoction assisted shoulder arthroscopic surgery on shoulder joint function and pain in patients with rotator cuff injuries.Methods:A total of 67 patients with rotator cuff injuries admitted to，Cangzhou Hospital of Integrated Traditional Chinese and Western Medicine from January 2016 to January 2018 were selected，and divided into the control group (n＝33) and treatment group (n＝34) according to random number table method.Both 2 groups underwent shoulder arthroscopic rotator cuff reconstruction surgery，and control group received conventional western medicine after surgery.The affected part of patients in treatment group was fumigated with Honghua Huayu Decoction at 2 weeks after surgery on the basis of control group，which was fumigated with 4 weeks.The clinical efficacy in 2 groups after 6 weeks surgery was counted.The situation of joint function and pain in 2 groups before and after surgery were evaluated and compared.Results:The clinical total effective rate in treatment group 6 weeks after surgery was 88.24%，which was higher than that 63.64% in control group (P<0.05).Compared with pre-surgery，the pain，shoulder joint function，active forward flexion，anteflexion power and subjective satisfaction scores from 4 weeks to 6 weeks after surgery increased (P<0.05).Treatment group was significantly higher than control group (P<0.05).Compared with pre-surgery，the angle of anteflexion，rear protraction，internal rotation and extorsion increased significantly 6 weeks after surgery in 2 groups (P<0.05)，and treatment group was significantly higher than control group (P<0.05).The joint of VAS scores 2 weeks to 6 weeks after surgery decreased in 2 groups (P<0.05)，and treatment group was significantly lower than control group 4 weeks，6 weeks after surgery compared with pre-surgery (P<0.05).Conclusion:Honghua Huayu Decoction assisted shoulder arthroscopic surgery can significantly improve the joint function of patients with rotator cuff injuries，alleviate joint pain.The efficacy is significantly better than that of conventional western medicine，which is worthy of clinical application.
