The influence of denervation therapy on knee joint function and the pain situation of patients with knee osteoarthritis complicated with cartilage injury

Objective: This study aimed to analyze the influence of denervation therapy on knee joint function and the pain situation of patients with knee osteoarthritis complicated with cartilage injury. Methods: 100 patients with knee osteoarthritis complicated with cartilage injury were selected for a retrospective analysis. According to the treatment method they received, the patients were divided into 2 groups, with 50 patients in the control group receiving arthroscopic knee debridement and 50 patients in the observation group receiving arthroscopic knee debridement combined with denervation therapy. We compared the therapeutic effects, their Lysholm ScoringStandards and Visual Analogue Scale (VAS) scores, and their complications. Results: The scores for knee joint function in the observation group were much higher than the scores in the control group at 6 months and 12 months after the operations (P<0.05). (2) The excellent rate of treatment in the observation group was higher than it was in the control group (X-2 =10.714, P<0.05). The VAS scores of the observation group were much lower than those of the control group at 1 month, 3 months, 6 months, and 12 months after the operations (P<0.05). The two groups showed no significant differences in their rates of the occurrence of complications (X-2 =0.344, P>0.05). Conclusion: Arthroscopic knee debridement combined with denervation therapy has an obvious therapeutic effect on knee osteoarthritis complicated with cartilage injury, which can improve knee joint function, relieve the degree of pain, reduce the rate of the occurrence of complications, and thus effectively promote patients' postoperative recovery.
