Official title
Anatomical Transportal ACL Reconstruction : Effect of Using 2 or 3 Portal Technique on Femoral Tunnel Position
Overview
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
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 ?
Interventions
- Radiation CT
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
Primary outcome measures
- Ct evaluation [Time frame: 1 day after surgery]
Secondary outcome measures (1)
- Clinical Examination & Functional scores [Time frame: at least 2 years after surgery]
