Tendon-to-bone fixation is the process of securely attaching a tendon or ligament graft to bone using devices such as bone tunnels, suture anchors, interference screws, cortical buttons, and suspensory fixation systems until biological healing occurs. Successful repair depends on both strong initial mechanical fixation and gradual tendon-to-bone biological incorporation at the enthesis. The choice of fixation method varies according to the procedure, tendon quality, bone quality, and biomechanical demands, with common applications including rotator cuff repair, ACL reconstruction, biceps tenodesis, patellar tendon repair, and Achilles tendon repair. Each fixation technique has unique advantages, indications, and potential complications such as anchor pullout, graft slippage, tunnel widening, and tendon-suture failure. Understanding the biomechanics, healing biology, implant selection, and rehabilitation principles is essential for optimizing surgical outcomes and long-term function.
