We hypothesized that the use of a graduated medical elastic thigh compression stocking for 14 days after total knee arthroplasty would reduce swelling by 2 cm and reduce pain among patients with a BMI ≥30 kg/m. The aim of this pilot study was to provide preliminary data and information about feasibility. The specified objectives were to investigate: 1) the level of post-surgical swelling and, 2) the level of post-surgical pain, 14 days after surgery.
In a randomized controlled pilot study, 44 patients were allocated to a graduated medical elastic thigh compression stocking or standard treatment for 14 days after total knee arthroplasty. Outcome measures were knee, calf, and ankle swelling and pain. Study feasibility included acceptable rates of written consent and compliance with the use of the compression stocking. Data was analyzed using two-sample t-test for equality of mean.
Overall, 68.8% of eligible patients gave written consent to participate in the study and 41.2% complied with use of the graduated medical elastic thigh compression stocking for 14 days post-surgery. No significant difference was found between the groups regarding knee, calf and ankle swelling or pain.
Knee swelling was reduced in both groups after 14 days, but was slightly more in the intervention group. The result is not statistically significant but indicates that a graduated medical elastic thigh compression stocking may have a positive effect on reduction of swelling after total knee arthroplasty. Initiating a larger scale randomized controlled study to determine effectiveness requires a higher level of compliance.
我们假设在全膝关节置换术后 14 天内使用梯度式医用弹性大腿压缩袜会使 BMI≥30kg/m2的患者肿胀减少 2cm，并减轻疼痛。本研究的目的是提供初步数据和可行性信息。具体目标是调查：1）手术后肿胀程度，以及 2）手术后 14 天的疼痛程度。
在一项随机对照的初步研究中，44 名患者被分配到梯度式医用弹性大腿压缩袜组或标准治疗组，在全膝关节置换术后 14 天内使用。测量指标为膝关节、小腿和踝关节肿胀和疼痛。研究可行性包括书面同意书的接受率和对压缩袜使用的依从性。数据使用两样本 t 检验进行分析。
总体而言，68.8%的合格患者书面同意参与研究，41.2%的患者遵守使用梯度式医用弹性大腿压缩袜 14 天的规定。两组间膝关节、小腿和踝关节肿胀或疼痛无显著差异。
两组患者在 14 天后膝关节肿胀均减轻，但干预组略多。结果无统计学意义，但表明梯度式医用弹性大腿压缩袜可能对全膝关节置换术后减轻肿胀有积极作用。要确定有效性，需要更高水平的依从性，才能开展更大规模的随机对照研究。
