The Modified Universiti Kebangsaan Malaysia Internal Bracing (MUIB) Autograft (Multi-Ligament) is a specialized ligament reconstruction construct designed to enhance the early biomechanical stability of multi-ligament knee reconstruction, particularly in complex injuries involving the Anterior Cruciate Ligament (ACL), Posterior Cruciate Ligament (PCL), and/or other stabilizing ligaments of the knee. Using the patient’s own autologous tendon tissue, such as hamstring, quadriceps, patellar tendon, or other suitable tendon grafts, the technique incorporates high-strength synthetic internal bracing alongside the biological grafts to provide additional mechanical reinforcement across the reconstructed ligaments.
A key feature of the MUIB Autograft is the integration of biological autograft tissue with an internal bracing system for multi-ligament reconstruction. This hybrid construct allows the reconstructed ligaments to benefit from the biological advantages of the patient's own tissue while providing additional mechanical support during the early postoperative period. The internal brace functions as a load-sharing reinforcement structure, helping to protect the autografts from excessive strain and maintaining construct stability while biological healing, graft incorporation, and ligamentization take place.
The MUIB Autograft (Multi-Ligament) is intended to address the increased mechanical demands and complexity associated with reconstructing multiple injured knee ligaments. By providing additional reinforcement to the reconstructed ligament(s), the construct is intended to reduce the risk of early graft elongation and excessive postoperative laxity, particularly during the initial rehabilitation phase when the biological grafts may not yet have achieved full structural integration. The additional mechanical support may facilitate a more controlled rehabilitation pathway while preserving the biological advantages of autologous tissue.
The primary target users are orthopedic surgeons performing multi-ligament knee reconstructions who require a reinforced autograft construct with enhanced early mechanical stability. The principal beneficiaries are patients with complex multi-ligament knee injuries who require reconstruction of two or more ligaments and may benefit from the use of their own biological tissue. The MUIB Autograft therefore combines the biological advantages of autologous tissue with the mechanical reinforcement of internal bracing to address the increased stability requirements of multi-ligament reconstruction and support restoration of knee stability and function.
