在健康个体中，Rolimeter、KLT、KiRA 和 KT-1000 关节测径器在前胫骨膝关节平移测量中的评估显示出可接受的内部评估者可靠性，但较差的外部评估者可靠性。

The evaluation of Rolimeter, KLT, KiRA and KT-1000 arthrometer in healthy individuals shows acceptable intra-rater but poor inter-rater reliability in the measurement of anterior tibial knee translation.

Abstract

PURPOSE

To assess measurement equivalence, inter- and intra-rater reliability, standard error of measurements (SEM) and false positive measurements (FPM) of four different knee arthrometers (KLT,Karl Storz; KiRA, I + ; KT-1000 MEDmetric Corp; Rolimeter, Aircast) in healthy patients.

METHODS

Four different investigators (two advanced (AR) and two beginners (BR)) examined 12 participants with healthy knees at two time points with regards to anterior tibial translation (ATT) and side-to-side difference (SSD). Test equivalence was assessed using the TOST (two-one-sided t test) procedure with ± 1 mm equivalence boundaries. Intraclass correlation coefficients (ICCs) were calculated using two-way mixed effects models. Furthermore, false positive-(SSD > 3 mm) and SEMs were assessed.

RESULTS

A total of 2304 Lachman Tests were performed. Between-rater SSDs were equivalent between AR and BR raters for the Rolimeter only. Inter-rater ICC values (SSD, ATT) were graded as "poor" to "moderate" for all devices. Equivalent test-retest results were observed for all raters using the Rolimeter, KLT and KT-1000, whereas measurement consistency with KiRA was given in the advanced examiners group only. Intra-rater ICC values (Range: SSD, ATT) were graded as "poor" to "moderate" for SSD values and "moderate" to "good" for ATT. SEMs were lowest for the Rolimeter and highest for KiRA. FPM were never obtained with the Rolimeter (0%), twice (2.1%) with the KT-1000, three times (3.1%) with the KLT and 33 times (34.4%) using KiRA.

CONCLUSION

There is acceptable intra-rater but poor inter-rater reliability with all tested arthrometers. Measures of knee laxity are comparable between Rolimeter, KLT and KT-1000 but higher for KiRA. Clinically, the present study shows that repeated arthrometry measurements should always be performed by the same investigators.

摘要

目的

评估四种不同膝关节测角计（KLT，Karl Storz；KiRA，I+；KT-1000 MEDmetric 公司；Rolimeter，Aircast）在健康患者中的测量等效性、组内和组间可靠性、测量标准误差（SEM）和假阳性测量（FPM）。

方法

四名不同的研究者（两名高级（AR）和两名初级（BR））在两个时间点检查了 12 名健康膝关节患者的胫骨前移（ATT）和侧间差异（SSD）。使用 TOST（双单侧 t 检验）程序评估测试等效性，采用±1mm 的等效边界。使用双向混合效应模型计算组内相关系数（ICC）。此外，还评估了假阳性（SSD＞3mm）和 SEM。

结果

共进行了 2304 次 Lachman 测试。仅 Rolimeter 的 AR 和 BR 评估者之间 SSD 的组间差异是等效的。所有设备的 SSD 和 ATT 的 ICC 值（SSD、ATT）均评定为“差”至“中”。Rolimeter、KLT 和 KT-1000 所有评估者的测试-再测试结果均等效，而 KiRA 仅在高级检查者组中给出了测量一致性。SSD 值的 ICC 值（范围：SSD、ATT）评定为“差”至“中”，ATT 的 ICC 值评定为“中”至“好”。Rolimeter 的 SEM 最低，KiRA 的 SEM 最高。Rolimeter 的 FPM 从未出现（0%），KT-1000 出现两次（2.1%），KLT 出现三次（3.1%），KiRA 出现 33 次（34.4%）。
