To investigate the clinical efficacy of arthroscopic capsular release and postoperative intra-articular infusion of cocktail combined with tranexamic acid (TXA) in the treatment of patients with frozen shoulder.
A total of 85 middle-aged and older patients with frozen shoulder who underwent arthroscopic capsular release and received intra-articular infusion of TXA alone (
Postoperative length of hospital stay was significantly shorter in the cocktail + TXA and cocktail groups than that in the TXA group. Postoperative drainage volume was significantly higher in the cocktail group compared with TXA + cocktail group (P < 0.05). At 1 day and 1 week after surgery, pain was more pronounced in the TXA group, which was significantly relieved in the cocktail and the cocktail + TXA groups (P < 0.05). Pain was significantly relieved in all the three groups at 1 and 3 months after surgery. Significant functional improvement of the shoulder was achieved in all three groups at 1 week after surgery, the improvement was apparent in the cocktail + TXA groups (P < 0.05), followed by the cocktail group. At 1 month after surgery, patients in the cocktail + TXA groups obtained excellent functional recovery of the shoulder joint. At 3 months after surgery, patients in all the three groups both obtained good recovery of the shoulder joint function, and the recovery was apparent in the cocktail + TXA groups (P < 0.05).
Arthroscopic capsular release and postoperative intra-articular infusion of cocktail combined with TXA has good safety and efficacy in the treatment of middle-age and older patients with frozen shoulder, which can reduce postoperative pain and intra-articular bleeding, promote early postoperative functional exercises and accelerate early postoperative recovery.
