目的

探讨射频消融术对类风湿关节炎患者膝关节功能改善的临床效果。

方法

回顾性分析选择2023年3月至2023年11月江苏大学附属医院收治的68例类风湿关节炎膝关节疼痛患者作为研究对象,其中男性19例,女性49例;年龄30~78岁[(54.3±10.3)岁]。根据研究对象是否行射频消融术分为对照组和消融组,每组各34例。对照组行口服药物镇痛;消融组行膝神经射频消融术。两组患者均进行基础抗风湿治疗。记录并比较两组患者治疗前后的疼痛数字评分(NRS)、Lysholm膝关节评分。记录并比较治疗前与治疗后第6个月两组患者类风湿因子(RF)和抗环瓜氨酸肽抗体(CCP)水平变化。

结果

两组随访6个月,所有患者均获随访。治疗前,两组患者间各项指标差异无统计学意义(P>0.05);治疗后,NRS、Lysholm膝关节评分均优于各组治疗前(P<0.05)。治疗后NRS、Lysholm膝关节评分、临床效果,消融组优于对照组(P<0.05)。RF、CCP水平,治疗前后两组患者间差异无统计学意义(P>0.05),各组治疗前与治疗后第6个月比较差异无统计学意义(P>0.05)。

结论

膝神经射频消融术较口服药物镇痛,对膝关节疼痛与功能有明显改善作用,且不影响类风湿病情变化。

Objective

To explore the clinical effect of radiofrequency ablation on knee joint pain and function improvement in patients with rheumatoid arthritis.

Methods

A total of 68 patients (19 males, 49 females) with knee pain secondary to rheumatoid arthritis (mean age, 54.3±10.3 years; range, 30~78 years) were consecutively enrolled from March to November 2023 at the Affiliated Hospital of Jiangsu University. Patients were randomized using a random number table into a control group (n=34) receiving oral analgesic medication and the RFA group (n=34) undergoing genicular nerve radiofrequency ablation. All patients continued to receive standardized background antirheumatic therapy. Pain intensity and knee function were assessed using the Numerical Rating Scale (NRS) and the Lysholm Knee Scoring Scale, respectively. Outcomes were evaluated before treatment and after the intervention, followed by between-group comparisons. Clinical efficacy was further assessed. Serum rheumatoid factor (RF) and anti-cyclic citrullinated peptide (CCP) antibody levels were measured at baseline and at 6 months post-treatment.

Results

All participants completed the 6-month follow-up. No statistically significant differences were observed in baseline characteristics or outcome measures between the two groups (P>0.05). Post-treatment assessments revealed significant within-group improvements in NRS and Lysholm scores (P<0.05). Between-group comparisons demonstrated that the RFA group exhibited significantly greater reductions in pain scores, more pronounced improvements in knee function, and higher clinical efficacy than the control group (P<0.05). RF and CCP levels did not differ significantly either between groups or within groups when comparing baseline with 6-month post-treatment values.

Conclusion

Genicular nerve radiofrequency ablation confers superior analgesic and functional benefits compared with oral analgesic therapy in patients with rheumatoid arthritis-related knee pain, without exerting measurable effects on serologic markers of disease activity.
