简要总结
Anterior cruciate ligament (ACL) tear is frequent, but the diagnosis of partial tears is difficult. Standard MRI may be used but is of limited diagnostic value. The present study aimed to evaluate the diagnostic interest of dynamic knee laxity measurement coupled to MRI for the diagnosis of ACL tear.

研究组 & 干预措施
laxIRM
Patients will have dynamic knee laxity measurement coupled to MRI for the diagnosis of ACL tear
干预措施: LaxIRM (Device)
结局指标
主要结局
Anterior tibial translation (ATT) measurement
时间窗: 1 year after the baseline MRI-scan
Time Frame : 1 year after the baseline MRI-scan a follow-up MRI is performed if the patient did not had surgery. ATT is calculated as the difference between the distance from the tangent to the condyle to the tangent to the posterior aspect of the tibial plateau in the stress position and in resting conditions. ATT is measured for the medial and the lateral compartment respectively and the final ATT is the average of medial and lateral ATT.
次要结局
- Degree of laxity(1 year after the baseline MRI-scan)
- Femorotibial rotation (FTR) value(1 year after the baseline MRI-scan)
