Assessment of the effect of biological polysaccharide colloidal solution to prevent re-adhesion after arthroscopic lysis of frozen shoulder

Objective To investigate the effect of joint irrigation with biological polysaccharide colloidal solution on pain and the rehabilitation process in patients, after arthroscopic lysis of frozen shoulder. Methods From March 2016 to November 2018, 68 patients with frozen shoulder were enrolled and randomly divided into two groups of 34 participants each:The observation and the control groups, respectively. Arthroscopic lysis was performed in both groups. In the observation group, the articular cavity was irrigated with biological polysaccharide colloidal solution after arthroscopic lysis. In the control group, only arthroscopic lysis was performed without the drug irrigation. The average follow-up period of the participants was 7.3 months. Visual analogue scale (VAS) score, American Shoulder and Elbow Surgeons (ASES) shoulder score, and University of California at Los Angeles (UCLA) shoulder score were used for evaluation before surgery and 6 months after surgery. The data of both groups were compared to assess the effect of the drug. Results All cases were followed-up. The comparative study of clinical data before surgery and 6 months after surgery, showed that VAS score in the observation group had decreased from (8.1±0.5) points before surgery to (0.9±0.4) points (t=65.564, P<0.05), while that, in the control group, had decreased from (8.3±0.4) points before surgery to (1.0±0.2) points(t=95.183, P<0.05). ASES score in the observation group had improved from (55.4±4.5) points before surgery to (93.3±2.6) points(t=42.522, P<0.05), while that in the control group had improved from (57.1±4.2) points before surgery to (82.5±3.1) points(t=28.372, P<0.05). UCLA score in the observation group had improved from (13.5±2.2) points before surgery to (30.3±1.6) points(t=36.012, P<0.05), while that, of the control group had improved from (12.9±2.4) points before surgery to (27.4±2.1) points(t=26.514, P<0.05). The differences in data before and after surgery between the two groups were statistically significant. Six months after surgery, there was no statistically significant difference in VAS score between the two groups (t=-1.304, P>0.05). The ASES score in the observation group was superior to that in the control group, with statistically significant difference (t=15.565, P<0.05). The UCLA score in the observation group was superior to that in the control group, with statistically significant difference (t=6.405, P<0.05). Conclusion Compared with conventional arthroscopic lysis surgery, irrigation with biological polysaccharide colloidal solution can effectively improve the shoulder joint function after surgery and prevent joint re-adhesion, and therefore it is worthy of clinical application.
