To describe the "three-portal technique for anatomical ACL single- or double-bundle reconstruction" and the arthroscopic viewing improvement provided by this technique.
A "high" anterolateral portal was placed 1 cm lateral to the patellar tendon and the most inferior portion of the portal at the level of the inferior pole of the patella. A "central" portal was placed using a spinal needle under arthroscopic visualization following the orientation of the previous ACL fibers. An accessory medial portal was also placed using a spinal needle respecting a 2-mm distance to the medial femoral condyle.
The "high" anterolateral portal permitted a broad and unobstructed view of the ACL tibial attachment. The "central" portal allowed a straightforward view of the ACL femoral remnant and bony landmarks in the intercondylar notch. The accessory medial portal enabled to reach the femoral native insertion site of the ACL.
The three-portal technique provides a proper view of the soft tissue remnants and bony landmarks facilitating an anatomical positioning of the graft.
描述“三入口技术在解剖 ACL 单束或双束重建中的应用”以及该技术提供的关节镜观察改善效果。
在前交叉韧带纤维的走向引导下,在髌腱外侧 1 厘米处和髌骨关节面下最下方位置建立一个“高位”前外侧入口(high anterolateral portal)。使用关节镜可视化技术,通过一根脊柱针在中心建立一个“中央”入口(central portal)。另外,通过一根脊柱针,距内侧股骨髁 2 毫米的位置建立一个辅助内侧入口(accessory medial portal)。
“高位”前外侧入口(high anterolateral portal)可提供宽阔且无阻碍的 ACL 胫骨附着处视野。“中央”入口(central portal)可直视 ACL 股骨残端和髁间窝内的骨性标志。辅助内侧入口(accessory medial portal)可到达 ACL 的股骨原始插入点。
三入口技术可提供软组织残端和骨性标志的适当视野,有助于移植的解剖定位。
