Ninety-nine ankle sprains were arbitrarily divided into a control (54 patients) and a study (45 patients) group. Both groups were treated with elevation, ice compression wraps crutches, and early mobilization. In addition, the study group underwent ankle joint aspiration and local injection of the involved ligaments with 4-10 cc of 1% xylocaine. The difference between recovery times in the control group (mean, 10.7 days) and in the study group (mean, 4.4 days) reached statistical significance at p less than 0.001 by Wilcoxon two-sample test. Because there are inherent risks in this treatment, it is not recommended for all patients. However, for those requiring early remission of symptoms to allow early return to pre-injury activities, this treatment is suggested by the author.
99例踝关节扭伤患者被随机分为对照组（54例）和研究组（45例）。两组均采用抬高患肢、冰敷、弹力绷带包扎、使用拐杖以及早期活动等治疗方法。此外，研究组还接受了踝关节穿刺抽吸，并向损伤的韧带局部注射4 - 10毫升1%的利多卡因。通过威尔科克森两样本检验，对照组（平均恢复时间为10.7天）和研究组（平均恢复时间为4.4天）恢复时间的差异在p值小于0.001时具有统计学意义。由于这种治疗存在内在风险，因此并非适用于所有患者。然而，对于那些需要症状早日缓解以便早日恢复伤前活动的患者，作者建议采用这种治疗方法。
