Lecture: ACL Fixation Technique and Preference


Early failure of ACL reconstruction happens due to the failure of ACL fixation. Thus, fixation in ACL reconstruction should be selected properly. Bone patella tendon bone (BPTB) graft stands for gold standard graft for long time. An interference screw has been developed and stays as a standard for fixation for BPTB graft. Proper techniques including, selection of the design and size of the screw also nondivergent insertion should be properly planned in order to get the good fixation. Hamstring graft has gained a high popularity in the past decade. The popular fixation of hamstring graft on the femoral side is a cortical fixation. In the case of short femoral tunnel, a modified technique has been proposed to solve to problem. Using adjustable loop fixation or interference screw help to resolve the problem.

Lecture: Medial side injury in multiple knee ligament injury


Multiple ligament knee injuries have complex pathologies that resulted from traumatic knee dislocations. Both clinical examination and radiographic evaluation are mandatory to diagnose and identify all injured structures. There are mix reports of good clinical outcomes on acute repair and early reconstruction. Reconstruction of medial side is challenging due to the nature of anatomy which none of the graft can replicate a band like structure that provides the stability for the knee. We advocate that every injured knee should be carefully examined and investigated to find the proper cases for acute repairing to avoid late reconstruction especially those who have persistent medial joint line opening on the plain x-ray, valgus stress test positive in full extension and severe soft tissue injury on the medial side. For the case with MRI demonstrates an entrapped or floating MCL, it should be reduced and fixed to its original anatomic attachment. In the case of irreparable or chronic case, we recommend using the remnant to tighten up the knee for example advancement of superficial MCL will tighten up for the valgus restrain and rewrapping of POL toward the front also secure posteromedial corner. After the attempt the repairing but still do not able to get the proper stability then reconstruction is a procedure to augment the repair site. In the setting of these complex reconstructions, there are several technical aspects that require consideration to ensure concise and efficient treatment of these injuries. Graft choice, sequence of reconstruction, tunnel position and orientation, and graft tensioning all pose surgical challenges, and require dedicated preoperative preparation and planning.
