Effect of Intra-articular Injection of Ropivacaine on Postoperative Analgesia and Local Inflammation of Patellar Fracture
This paper analyse the effect of intra-articular injection of ropivacaine on postoperative analgesia and local inflammation of patellar fracture. The 120 patients were divided into four groups, A, B, C and D, with 30 cases in each group. All patients were treated with arthroscopic minimally invasive surgery. In group A, B, C and D, saline was used in group A, and 0.25%, 0.375% and 0.5% ropivacaine was injected into articular cavity in group B, C and D, respectively. The pain scores, levels of inflammatory factors, activity and incidence of adverse reactions were compared between the two groups. Compared with the other three groups, group D had significant data advantages in terms of postoperative pain at different time points, and the difference was significant (P < 0.05); group B and C had significant data advantages in terms of pain score at different time points after operation compared with group A, and the difference was significant (P < 0.05). At 2 hours after operation, the indexes of inflammatory factors in four groups were significantly improved, the data difference was not prominent, and the comparison results were meaningless (P > 0.05); at 24 hours after operation, the indexes of inflammatory factors in B, C and D groups were significantly better than those in A group, and the data in D group were significantly superior to those in the other three groups. The results were significant (P < 0.05). There was no significant difference in the range of motion between the two groups before operation (P > 0.05). The range of motion in group B, C and D after operation was significantly better than that in group B, C and D, with significant difference in data (P < 0.05). There was no significant difference in the incidence of adverse reactions between the four groups (P > 0.05). Ropivacaine intra-articular injection has a prominent effect on pain relief and local inflammation after patellar fracture surgery. It can effectively alleviate knee pain and inflammation, promote patients to participate in rehabilitation training of joint function better, improve the quality of prognosis and life. It is worth promoting.
