What fixation techniques are available for ACL grafts?

• A. Metal plates and screws only
• B. Interference screws, staples, and sutures through bones
• C. Only sutures tied over screw posts
• D. Cement fixation and bone grafting

Answer: (B)

The fixation techniques for ACL grafts primarily involve the use of interference screws, staples, and sutures through bones, which are all designed to provide strong and reliable attachment of the graft to the bone. Interference screws are commonly used in ACL reconstruction because they allow for compression of the graft against the bone tunnel, facilitating healing by promoting osseointegration. The use of staples can provide additional fixation, especially in certain surgical approaches. Sutures threaded through the bone help to secure the graft as well, ensuring it remains stable during the critical healing period. Other fixation methods, such as metal plates and screws or cement fixation and bone grafting, are not standard practices for ACL graft fixation. While sutures tied over screw posts can be a form of securing grafts, they do not encompass the variety of techniques available, making the specified methods in the correct answer the most comprehensive and commonly utilized in modern ACL reconstructive surgery.
