Effects of arthroscopic rotator cuff repair on shoulder joint function and bone density of the greater tubercle of humerus in patients with rotator cuff tear and osteoporosis
Objective To investigate the effects of shoulder arthroscopic rotator cuff repair on shoulder joint function and bone density of the greater tubercle of humerus in patients with rotator cuff tear(RCT)and osteoporosis(OP).Methods One hundred RCT patients with OP admitted to our hospital from January 2022 to January 2023 were retrospectively selected as research objects.All were divided into open surgery group(n = 49)and shoulder arthroscopic group(n = 51)according to treatment methods.Surgical time,intraoperative blood loss,length of hospitalization,shoulder joint function preoperatively and 6 months postoperatively[American Society for Shoulder-Elbow Surgery(ASES)score,Constant shoulder joint function(Constant)score],humeral greater tubercle bone density,trauma quantitative indicators preoperatively and 3 days postoperatively[interleukin-6(IL-6),C-reactive protein(CRP)],and the incidence of surgical complications were compared between the two groups.Results Intraoperative blood loss was less in the shoulder arthroscopy group than that in the open surgery group[(27.88±5.36)vs.(52.49±6.95)];the length of hospitalization was shorter in the shoulder arthroscopy group than that in the open surgery group[(7.67±1.30)vs.(12.52±2.17)];the differences were statistically significant(P<0.05).There was no significant difference in the operative time between the two groups(P>0.05).Six months postoperatively,the ASES score was higher in the shoulder arthroscopy group[(78.21±8.34)vs.(67.08±7.69)],and the Constant score was higher in the shoulder arthroscopy group than that in the open surgery group[(76.59±8.17)vs.(68.23±7.51)];the differences were statistically significant(P<0.05).There was no statistically significant difference in the bone density of the humeral tuberosity 6 months postoperatively between the two groups(P>0.05).Three days after surgery,serum IL-6 levels were lower in the shoulder arthroscopy group than that in the open surgery group[(13.55±5.18)vs.(19.72±6.47)];the serum CRP levels were lower in the shoulder arthroscopy group than in the open surgery group[(12.64±3.51)vs.(17.22±4.38)];the differences were statistically significant(P<0.05).Complications occurred in 3 cases in the shoulder arthroscopy group(5.88%)and 8 cases in the open surgery group(20.41%).Complication rate in the shoulder arthroscopy group was lower than that in the open surgery group,and the differences were statistically significant(P<0.05).Conclusions Arthroscopy rotator cuff repair in RCT patients with OP has advantages in reducing intraoperative blood loss,reducing surgical trauma,decreasing the occurrence of complications,shortening hospitalization time,and improving shoulder function,with less effect on the density of the greater tuberosity of the humerus.
