Arthroscopic ACL Revision Surgery

Revision ACL procedures require meticulous planning due to the altered anatomy from the first reconstruction. Surgeons must carefully assess several key factors:

• Condition of the previous graft: Understanding whether failure was caused by trauma, poor healing, or technical errors.
• Bone tunnel position: Incorrect tunnels from the earlier surgery can create abnormal knee mechanics and must be corrected.
• Tissue quality: Scar tissue, weakened ligaments, or compromised bone structure may complicate the procedure.
• Additional injuries: Meniscus tears, cartilage loss, or secondary ligament injuries often require simultaneous repair.

1. Detailed Assessment
   The revision process begins with a thorough evaluation. Physical examination, X-rays, and MRI scans help determine the cause of failure, tunnel placement, and the overall joint condition.
2. Pre-Operative Planning
   A personalized surgical plan is created. In some cases, a staged approach is needed—for example, bone grafting may be done first to fill old tunnels before proceeding with the revision reconstruction.
3. Graft Selection
   Options include:
   • Autograft: The patient’s own tissue, often hamstring, peroneous  or patellar tendon.
   • Allograft: Donor tissue, carefully processed for safety and strength.
     The choice depends on activity level, stability requirements, and tissue quality.
4. Arthroscopic Reconstruction
   Through small incisions, the surgeon removes the failed graft and any remaining hardware. New tunnels are drilled in anatomically correct positions, and the new graft is secured using fixation devices such as screws or buttons.
5. Additional Repairs
   Meniscus or cartilage damage, if present, is repaired arthroscopically during the same procedure. This ensures comprehensive treatment and long-term stability.

Rehabilitation after arthroscopic ACL revision surgery is typically longer and more cautious than after a primary reconstruction. Patients can expect:

• Initial Protection: A knee brace and crutches are used to safeguard the new graft.
• Gradual Weight-Bearing: Progress depends on graft integrity and any additional procedures performed.
• Structured Physiotherapy: Focused on regaining range of motion, rebuilding quadriceps and hamstring strength, and restoring balance.
• Return to Sports: Usually after 9–12 months, though some patients may require more time depending on healing and adherence to rehabilitation.

The outcome of arthroscopic ACL revision surgery depends on the cause of initial failure, graft quality, surgical precision, and patient commitment to rehabilitation. While results can be excellent, it is important to recognize that the knee may not fully return to its pre-injury condition. Long-term success relies on disciplined rehabilitation, lifestyle modifications, and preventive care to protect the reconstructed ligament.

Arthroscopic ACL (Anterior Cruciate Ligament) revision surgery in Chennai offers a minimally invasive yet highly effective solution for failed or re-injured ACL reconstructions. Using advanced techniques, precise surgical planning, and a structured rehabilitation program, patients can successfully regain knee stability, restore full mobility, and confidently return to their active lifestyles with improved long-term joint function.
