摘要

目的：本研究的主要目的是根据单腿跳跃测试（SLH）的肢体对称性指数（LSI），评估动态韧带内稳定（DIS）手术后膝关节功能表现与健康对照组相比，在最短随访1年内的非劣势。此外，还对单腿三跳测试（SLTH）和侧跳测试（SH）的功能表现、本体感觉和主观结果进行了评估：方法：将 45 名 DIS 患者与健康对照组进行 1 对 1 配对。功能表现通过LSI和SLH、SLTH和SH的绝对值进行评估。通过关节位置感（JPS）测试和国际膝关节文献委员会（IKDC）评分来评估运动感觉：结果：根据SLH和SLTH的平均LSI（分别为97.6% vs. 99.6%和97.5% vs. 100.6%），证实DIS后的功能表现与健康对照组相比没有劣势，而SH的平均LSI（分别为98.8% vs. 100.0%）没有得到证实。SLH和SLTH的绝对值无明显差异，而DIS组的SH绝对值明显更高（p = 0.01）。与对照组相比，DIS 组的 JPS 绝对角度误差明显更高（p = 0.01）。DIS 组的 IKDC 评分中位数（92，IQR 85-95）明显低于对照组（100，IQR 99-100），P 结论：DIS 组的 IKDC 评分中位数（92，IQR 85-95）明显低于对照组（100，IQR 99-100）：总之，根据SLH和SLTH，DIS后的功能表现证实不劣于健康对照组，但SH未经证实：证据等级：三级。

Successful ACL repair by dynamic intraligamentary stabilisation is non-inferior in functional performance and worse in proprioception compared to healthy controls in a case-matched study

Purpose

The primary aim of this study was to assess non-inferiority in functional performance of the knee after dynamic intraligamentary stabilisation (DIS) surgery at a minimal follow-up of 1 year compared to healthy controls, based on limb symmetry index (LSI) of the single leg hop test (SLH). Additionally, functional performance based on the single leg triple hop test (SLTH) and side hop test (SH), proprioception and subjective outcome were evaluated.

Methods

A total of 45 DIS patients were 1-to-1 matched to a healthy control. Functional performance was evaluated by LSI and absolute values on the SLH, SLTH and SH. Proprioception was assessed by joint position sense (JPS) test and International Knee Documentation Committee (IKDC) scores were obtained.

Results

Non-inferiority in functional performance after DIS compared to healthy controls was confirmed based on the mean LSI of the SLH and SLTH (97.6% vs. 99.6% and 97.5% vs. 100.6%, respectively) and non-confirmed on the SH (98.8% vs. 100.0%, respectively). No significant differences were found in absolute value of the SLH and SLTH and a significantly higher absolute value of the SH was found in the DIS group (p = 0.01). JPS absolute angular error was significantly higher in the DIS group compared to the control group (p = 0.01). The median IKDC score of the DIS group was significantly lower (92, IQR 85–95) than the control group (100, IQR 99–100), p < 0.001.

Conclusions

In conclusion, functional performance after DIS was confirmed non-inferior compared to healthy controls based on the SLH and SLTH, although non-confirmed on the SH.
