Proximal Tibia Tumour Resection and Neo Patellar Tendon Reconstruction with Hamstring Tendon

Description

This video tutorial presents a comprehensive overview of a surgical procedure for proximal tibia tumor resection and neo patellar tendon reconstruction using harvested hamstring tendons. It begins with an introduction and surgical planning, highlighting the importance of radiographs and MRI for accurate tumor resection length. The patient is positioned supine to optimize access, followed by the step of making a medial incision to visualize the surgical area. The procedure proceeds with the detachment of the patellar tendon to maintain soft tissue integrity. The hamstring tendons, semitendinosus and gracilis, are harvested and braided for reconstruction of the extensor mechanism. A tumor resection is performed based on MRI findings, ensuring a safe margin for complete removal of malignant tissue. Reconstruction of the bony defect is executed using a modular proximal tibia mega prosthesis, and the neo patellar tendon is reconstructed and attached to the implant. Additionally, the medial gastrocnemius muscle is harvested to enhance the protection of the new tendon and implant. After securing the prosthesis, the soft tissues are closed in layers, and post-operative care is discussed, including knee bracing and rehabilitation protocols for recovery.
