Abstract：
UNASSIGNED: This study aims to systematically compare the efficacy of two distinct approaches that is limb occlusion pressure (LOP) and systolic blood pressure (SBP) in determining the optimal tourniquet pressure for primary total knee arthroplasty. The overarching goal is to identify the method that yields superior outcomes in minimizing post-operative thigh pain while simultaneously reducing complications in our patient population.
UNASSIGNED: 311 patients scheduled for primary total knee replacement (TKR) were randomized in two groups. Group A (LOP) had 154 patients and group B had 157 patients. In group A, LOP was determined for all patients. After adding the safety margin, the tourniquet pressure was determined which was kept during the procedure. By adding 150 mm Hg to SBP in group B, the tourniquet inflation pressure was ascertained. Postoperatively, thigh pain was evaluated from day 1 to day 3 and at 6 weeks.
UNASSIGNED: The average tourniquet pressure in group A patients having thigh circumference between 40 and 50 cm was 223.8 mm + - 19.8 mm Hg and in group B it was 262.1 + - 15.9 mm Hg (P < .01). Patients having thigh circumference between 51 and 60 cm had average tourniquet pressure of 240.07 + - 20.1 mm Hg in group A and 264.5 + - 17.4 mm Hg in group B (P < .01). The average tourniquet pressure for patients with thigh circumference more than 60 cm was 296 + /15.3 mm Hg in group A and 267.3 + /19.2 mm Hg in group B (P < 0.01).
UNASSIGNED: Tourniquet pressure determination based on the limb occlusion pressure (LOP) method provide less postoperative thigh pain and better range of motion.
UNASSIGNED: Optimizing Tourniquet Pressure in Primary Total Knee Replacement: Limb Occlusion Pressure vs Systolic blood pressure method to minimize thigh pain.

摘要：
■本研究旨在系统地比较两种不同方法的疗效，即肢体闭塞压（LOP）和收缩压（SBP），以确定初次全膝关节置换术的最佳止血带压力。总体目标是确定一种方法，该方法可在最大程度地减少术后大腿疼痛，同时减少我们患者人群的并发症。
■311例初次全膝关节置换术（TKR）患者随机分为两组。A组（LOP）有154例患者，B组有157例患者。在A组中,确定所有患者的LOP。添加安全裕度后，确定止血带压力，该压力在手术过程中保持不变。通过在B组中增加150mmHg到SBP，确定了止血带充气压力。术后,从第1天到第3天和第6周评估大腿疼痛。
■大腿围在40至50cm之间的A组患者的平均止血带压力为223.8mm-19.8mmHg，而B组为262.1-15.9mmHg（P<.01）。大腿围在51至60cm之间的患者，A组的平均止血带压力为240.07-20.1mmHg，B组的平均止血带压力为264.5-17.4mmHg（P<0.01）。大腿围大于60cm患者的平均止血带压力A组为296+/15.3mmHg,B组为267.3+/19.2mmHg(P<0.01)。
■基于肢体闭塞压力（LOP）方法的止血带压力测定可提供更少的术后大腿疼痛和更好的运动范围。
■在初次全膝关节置换术中优化止血带压力：肢体阻塞压力与收缩压方法，以最大程度地减少大腿疼痛。
