Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Our research is to evaluate the position and length of femoral tunnel, and to examine whether knee stability and clinical functional outcomes are better while using two-portal or three-portal technique .

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Arthroscopic anterior cruciate ligament (ACL) reconstruction is one of the most often performed orthopedic surgeries . Restoration of normal anatomy after ACL reconstruction is related to achieve better function and a satisfactory long-term outcomes. The principles for anatomical ACL reconstruction are to functionally reestablish the ACL to its native dimensions, collagen orientation and insertion sites . The basis for the completion of these principles lies in the correct identification of the insertion sites. The conventional 2-portal technique uses the anterolateral portal as the viewing portal and the anteromedial portal as the working portal. the 3-portal technique allows interchangeable use of the portals as a viewing and working portals depending on the specific task that is being performed. The internal joint anatomy, as soft tissue remnants and bony landmarks, should guide the placement of the portals in ACL anatomical reconstruction and that each of the portals has a specific role during ACL anatomical reconstruction . So does the improved visualization through 3-portal technique compared to 2-portal technique have an impact on femoral tunnel position ?

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

2 portal group

The conventional 2-portal technique uses the anterolateral portal as the viewing portal and the anteromedial portal as the working portal

CT

Intervention Type RADIATION

3D CT scan have been used to evaluate the tunnels location after ACL reconstruction, as they can provide excellent perspective of the tunnel aperture, good visualization of bony structure and shape of the intercondylar notch, that preclude the use of a conventional 2-dimensional CT scan for measurement of the ACL tunnels location

3 portal group

the 3-portal technique allows interchangeable use of the portals as a viewing and working portals depending on the specific task that is being performed

CT

Intervention Type RADIATION

3D CT scan have been used to evaluate the tunnels location after ACL reconstruction, as they can provide excellent perspective of the tunnel aperture, good visualization of bony structure and shape of the intercondylar notch, that preclude the use of a conventional 2-dimensional CT scan for measurement of the ACL tunnels location
