Total knee arthroplasty is used to treat end-stage knee osteoarthritis with great results. Tourniquet use has become popular over the years because of its various benefits, but the literature regarding functional outcomes, pain and rehabilitation and comparison between tourniquet use and improvement cement penetration and overall improve fixation is limited. The authors proposed a hypothesis that cementation quality, and clinical outcomes can be influenced by tourniquet technique.
Fifty patients were allocated randomly in two groups: (1) tourniquet was inflated throughout all the procedure and (2) only during skin incision and cementation. Radiolucent lines were analyzed by two and independent examiners, using the The Knee Society Roentgenographic Evaluation and Scoring System. The functional scores used were the Oxford knee score and improvement in visual pain scale (VAS).
After a mean follow-up period of 2.4 ± 0.2 years, no difference was observed regarding partial use of tourniquet in the cementation quality (p value > 0.05). There was no difference between groups regarding gender, age, knee side, Visual VAS, Oxford Score, total range-of-motion (ROM), knee extension and knee flexion (p value > 0.05).
No difference was attained regarding functional outcomes and cementation quality regarding two different tourniquet protocols.
全膝关节置换术被用于治疗终末期膝骨关节炎，疗效显著。多年来，由于其诸多益处，止血带的使用变得越来越流行，但关于止血带使用对功能结果、疼痛和康复的影响，以及与止血带使用和改善水泥渗透以及整体改善固定的比较的文献有限。作者提出了一个假设，即 固定质量和临床结果可能会受到止血带技术的影响。
将 50 名患者随机分配到两组：（1）止血带在整个手术过程中充气；（2）仅在皮肤切开和水泥固定时充气。使用膝关节学会放射学评估和评分系统，由两名独立的检查者分析透明线。使用的功能评分是牛津膝关节评分和视觉疼痛量表（VAS）的改善。
平均随访 2.4±0.2 年后，在水泥固定质量方面，部分使用止血带没有差异（p 值>0.05）。两组之间在性别、年龄、膝关节侧、视觉 VAS、牛津评分、总活动范围（ROM）、膝关节伸展和膝关节屈曲方面没有差异（p 值>0.05）。
两种不同的止血带方案在功能结果和水泥固定质量方面没有差异。
