This study is the first to evaluate whether continuous cryotherapy can relieve pain soon after total hip arthroplasty (THA). Patients who had undergone THA for osteoarthritis were divided into 2 prospective, randomized groups: the cryotherapy group was fitted with a computer-controlled cooling device for 4 days, and the control group was not. The pain scores measured on a visual analog scale between days 1 and 4 following surgery were significantly lower for the cryotherapy group than for the control group. Furthermore, postoperative analgesic use by the cryotherapy group was significantly lower than by the control group. The results of this study support the potential benefit of a cold compressive device for pain reduction during the postoperative recovery of patients undergoing THA.
本研究首次评估了持续冷冻疗法能否在全髋关节置换术（THA）后迅速缓解疼痛。因骨关节炎接受THA的患者被分为2个前瞻性随机组：冷冻疗法组配备计算机控制的冷却装置4天，对照组则未配备。术后第1天至第4天使用视觉模拟量表测量的疼痛评分，冷冻疗法组显著低于对照组。此外，冷冻疗法组术后镇痛药的使用量也显著低于对照组。本研究结果支持了在接受THA患者的术后恢复过程中，使用冷压缩装置减轻疼痛的潜在益处。
