刺骨术治疗膝骨关节炎临床观察

目的 观察刺骨术治疗膝骨关节炎（knee osteoarthritis，KOA）的临床疗效和安全性。方法 共纳入30例KOA患者，应用刺骨术治疗。于治疗前、治疗后1周及治疗后4周，分别采用WOMAC量表对患者膝关节的疼痛、僵硬及关节功能进行评定。结果 治疗后1周，患膝的疼痛、僵硬及关节功能评分均较治疗前明显降低（P＜0.01）；与治疗后1周比较，治疗后4周，3项评分均又明显降低（P＜0.01）。整个研究期间30例患者均未出现任何并发症。结论 刺骨术可改善KOA患者膝关节的疼痛症状和关节功能，是一种安全有效的治疗方法。

Clinical Efficacy of Bone Decompression Needle in Treatment of Knee Osteoarthritis

Objective To evaluate the clinical efficacy and safety of bone decompression needle in the treatment of knee osteoarthritis (KOA). Methods This study included 30 KOA patients who were treated with the bone decompression needle. Before treatment and at one and four weeks after treatment, the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) was used to assess pain, stiffness, and function of the knee joint. Results These patients had significantly reduced WOMAC scores for pain, stiffness, and function of the knee joint at one week after treatment (P<0.01), and the three scores were further reduced from one to four weeks after treatment (P<0.01). None of the 30 patients developed complications during the study period. Conclusion For patients with KOA, the bone decompression needle can relieve the pain and improve the function of knee joint, and it is a safe and effective therapy.
