- Scientific TitleIn vivo analysis of tibial rotation after anatomical versus trans-tibial anterior cruciate ligament reconstruction surgery.
- ACRONYM
- hypothesisTheoretically the anatomical reconstruction technique might give better results in rotational stability due to a more anatomical placement of the ACL-graft. Though it is difficult to test this correlating to functional outcome, because in current literature there seems to be no significant difference between both surgical techniques. Moreover, statically performed anterolateral rotational instability tests do not reproduce the forces loaded onto an in vivo anterior cruciate ligament. Through in vivo kinematic 3D- gait analysis, we aim to measure statistically and clinically significant differences in tibial rotational excursion when patients perform several motor tasks.

- InterventionsThe transtibial ACL reconstruction. In this technique the orientation of the femoral tunnel depends on the orientation of the tibial tunnel, because the femoral tunnel is created through the tibial tunnel. In this way a non-anatomical reconstruction is performed.

The anatomical ACL reconstruction aims to better restore this rotational stability by placing an extra anteromedial arthroscopy portal through which the femoral tunnel can be reamed more laterally and more diagonally oriented, hereby placing the graft in a more anatomical orientation similar to the native ACL.
- Primary outcomeOur first outcome of interest will be the tibial rotation excursion. This is the graph which we can draw from our gait analysis system which measures the position of the tibia in relation to that of the femur and allows us to see the angle of rotation.
- Secondary outcomeAdditionally, we keep track of our patients' well-being and satisfaction using several questionnaires. We will use questionnaires and clinical tests that have been recommended by the Nederlandse Orthopaedische Vereniging (NOV):
1. Knee Injury and Osteoarthritis Outcome score (KOOS) (Questionnaire);
2. International Knee Documentation Committee (IKDC) (Questionnaire);
3. Tegner sports activity score (Questionnaire);
4. Lachman Test (Clinical Test);
5. Anterior Drawer Test (Clinical Test);
6. Pivot Shift Test (Clinical Test).
We will also take several other values into account that the VICON system generates automatically when we perform our 3D gait analysis:
1. Dynamic EMG Measurement;
2. Knee moments;
3. Foot approach angle.
- TimepointsOn the Gait-lab test day participants will be required to come to the Maastricht University Movement Laboratory. On this day they will follow the regimen described below.

Test day Schedule:
1. Physical examination (5-10 minutes);
2. EMG placement and maximum force determination (10-15 minutes);
3. Skin marker placement (5-10 minutes);
4. Skin marker calibration (5-10 minutes);
5. Vicon Gait analysis (10 minutes);
6. Questionaires (10-20 minutes).
Total time 35-55 (47-75) minutes

- Brief summaryExperiments dealing with the rotational stability after an ACL reconstruction have not been performed in vivo or were performed under static conditions. Although static rotational stability testing is currently the standard, many studies have shown that static stability tests are often incapable of correlating with functional outcome following anterior cruciate ligament-reconstruction-surgery. Through in vivo testing in dynamic weight bearing knees we expect to get a better view of the actual rotational pivoting forces in the knee.

Participants will be recruted by Dr P Deckers (MD) from the Dep. of Orthopedic surgery Atrium MC in Heerlen, Dr P Emans (MD, PhD) from the Dep. of Orthopedic surgery AZM in Maatricht and Dr EJP Jansen (MD, PhD) from the Dep. of Orthopedic surgery Orbis MC in Sittard-Geleen.
