To assess the relationship between the KiRA triaxial accelerometer and the KT-1000 measurements in the intact, anterior cruciate ligament (ACL) deficient, and ACL reconstructed knee joint for the quantification of the Lachman test. Moreover, the intra- and inter-examiner repeatability of the KiRA device will be determined. It was hypothesized that the side-to-side difference of the anterior tibial translation as measured by the KiRA device would be equivalent to the one measured by the KT-1000 during the Lachman test.
Sixty patients were divided into three groups and have been prospectively included in the present study. Group_A composed of 20 patients with a diagnosis of an isolated ACL tear. Group_B composed of 20 patients who underwent ACL reconstruction with a Single-Bundle Lateral Plasty (SBLP) technique with at least 20 years of follow-up. Group_C was the control group and included 20 patients with no history of ACL lesion. Lachman test has been performed at manual-maximum load on both sides, the involved and the contralateral and analyzed with the two different devices.
The KiRA device in terms of side-to-side difference resulted not statistically different from the measurement of the KT-1000 arthrometer for the three study groups (n.s): Group_A: (4 ± 2 mm KiRA, 4 ± 2 mm KT1000), Group_B: (4 ± 2 mm KiRA, 4 ± 2 mm KT-1000), Group_C: (4 ± 2 mm KiRA, 4 ± 2 mm KT-1000), an excellent intra- (ICC = 0.88-0.89) and inter-examiner (ICC = 0.79) agreement was found for KiRA measurements.
The KiRA (I+, Italy) device offers a valid method to quantify the Lacham test.

评估 KiRA 三轴加速度计与 KT-1000 在完整、前交叉韧带（ACL）缺失和 ACL 重建膝关节中的测量值之间的关系，以定量测量 Lachman 试验。此外，还将确定 KiRA 设备的内部和外部检查者的可重复性。假设 KiRA 设备测量的胫骨前移的侧间差异将等同于 Lachman 试验中 KT-1000 测量的差异。
将 60 名患者分为三组，并前瞻性纳入本研究。A 组由 20 名诊断为 ACL 撕裂的患者组成。B 组由 20 名接受 ACL 重建的患者组成，采用单束外侧成形术（SBLP）技术，随访时间至少 20 年。C 组为对照组，包括 20 名无 ACL 损伤病史的患者。在双侧手动最大负荷下进行 Lachman 试验，对受累侧和对侧进行分析，使用两种不同的设备进行分析。
KiRA 设备在三个研究组中（n.s）的侧间差异与 KT-1000 关节计的测量值无统计学差异：A 组：（4±2mm KiRA，4±2mm KT1000），B 组：（4±2mm KiRA，4±2mm KT-1000），C 组：（4±2mm KiRA，4±2mm KT-1000），KiRA 测量的内部（ICC=0.88-0.89）和外部检查者（ICC=0.79）的一致性均极好。
KiRA（I+，意大利）设备提供了一种有效的方法来定量测量 Lacham 试验。
