[New Technique of Anterior Cruciate Ligament Reconstruction Using Hamstrings - the Surgical Instrumentation Set]

Area of Science:

• Orthopedic Surgery
• Biomedical Engineering
• Sports Medicine

Context:

• Anterior cruciate ligament (ACL) reconstruction success relies on graft fixation, surgical technique, and surgeon experience.
• Hamstring (HS) tendon grafts require specific fixation methods within the bone tunnel, differing from Bone-Tendon-Bone (BTB) grafts.
• Existing methods for HS graft fixation present challenges in achieving optimal stability and precise placement.

Purpose:

• To present the development and evaluation of a novel instrumentation set for ACL reconstruction utilizing hamstring tendons.
• To detail the construction, methodology, and surgical application of the new instrumentation system.
• To assess the surgical outcomes and technical advantages of the developed instrumentation set.

Summary:

• The developed instrumentation set facilitates ACL reconstruction with four-strand HS grafts, employing a unique femoral screw with an eyelet and a tibial interference screw.
• The system allows for graft fixation via femoral screw insertion through the tibial tunnel and intra-articular space, verified by a measuring gauge.
• Key advantages include simplified instrumentation, secure graft fixation, precise positioning of the interference screw, and the ability for post-insertion graft tensioning.

Impact:

• The new instrumentation set simplifies the surgical technique for ACL reconstruction with HS tendons, reducing potential errors and operative time to approximately 30 minutes.
• The system's user-friendliness and logical procedural steps contribute to enhanced surgical efficiency and safety.
• No major complications or technical errors were reported, indicating the set's efficacy and reliability in clinical practice.
