Revision ACL surgery is a procedure performed to repair a previously failed anterior cruciate ligament (ACL) reconstruction. It is estimated that around 10% of ACL reconstructions fail within 10 years. The main reasons for ACL reconstruction failure include technical issues with the original surgery, untreated secondary instabilities, traumatic reinjuries, and biologic issues. Revision ACL surgery is a more complex procedure compared to the primary reconstruction, requiring a thorough evaluation of the previous surgery, alignment, secondary restraints, and graft size and placement. The success rates for ACL revision surgery are approximately 75%, and the rehabilitation process may take longer than the primary surgery.

Key Takeaways:

• Revision ACL surgery is performed to address a failed ACL reconstruction.
• About 10% of ACL reconstructions fail within 10 years.
• The main reasons for ACL reconstruction failure include technical issues, untreated instabilities, reinjuries, and biologic issues.
• Revision ACL surgery is a more complex procedure and requires a thorough evaluation.

Timing and Indications for Revision ACL Surgery

The timing for revision ACL surgery is determined based on several factors, including the patient’s symptoms, stability, desired activity level, and imaging findings. It is crucial to undergo a thorough evaluation to accurately assess the need for a revision surgery.

Indications for revision ACL surgery include:

• Recurrent instability or persistent symptoms despite extensive rehabilitation
• Presence of knee instability during physical examination
• Desire to return to cutting and pivoting sports
• Presence of other knee injuries that may affect the outcome of the revision surgery

By carefully considering these indications, surgeons can identify patients who would benefit from revision ACL surgery and determine the appropriate timing for the procedure.

Evaluating the Patient’s Symptoms and Stability

During the evaluation process, the surgeon will assess the patient’s symptoms, such as recurrent instability, pain, and functional limitations. The surgical team will also evaluate the stability of the knee joint to determine if there is any residual laxity or abnormal movement.

If the patient experiences recurrent instability despite completing an extensive rehabilitation program, revision ACL surgery may be recommended to address the underlying issues that led to the failure of the initial reconstruction.

Imaging Findings and Desired Activity Level

Imaging studies, such as magnetic resonance imaging (MRI), and CT scans can provide valuable information about the condition of the previous ACL reconstruction, the presence of concurrent injuries, and the size and placement of the graft.

The desired activity level of the patient is another critical factor to consider. If the patient wishes to return to high-impact activities, cutting, pivoting sports, or professions that require knee stability, revision ACL surgery may be necessary to achieve these goals.

Reasons for ACL Reconstruction Failure

The success of an ACL reconstruction surgery depends on several factors, and unfortunately, failures can occur. Understanding the reasons for ACL reconstruction failure is crucial in planning a revision surgery and improving the outcome for patients. The most common causes of ACL reconstruction failure include:

1. Technical errors: Technical errors during the original surgery, such as misplaced graft reconstruction tunnels, can contribute to the failure of the ACL reconstruction. These errors can result in improper graft placement or inadequate stabilization of the knee joint.
2. Untreated secondary instabilities: Secondary instabilities, such as posterolateral corner injuries or meniscal root detachments, that were not addressed during the initial surgery can lead to ACL reconstruction failure. These secondary issues can affect the stability of the knee and the success of the reconstructed ACL.
3. Traumatic reinjuries: Traumatic reinjuries to the knee, particularly during high-impact or pivoting activities, can cause the reconstructed ACL to fail. These reinjuries can disrupt the healing process or damage the graft.
4. Biologic issues: Biologic issues, such as problems with graft incorporation or an early return to high-level activities, can contribute to ACL reconstruction failure. Insufficient graft healing, abnormal tissue response, or excessive stress on the reconstructed knee can hinder the success of the surgery.

Identifying the specific cause of ACL reconstruction failure is essential for developing an effective treatment plan for revision ACL surgery. By addressing the underlying issues, surgeons can improve the chances of a successful revision surgery and help patients regain stability and function in their knee.

Evaluating the Need for Revision ACL Surgery

When considering revision ACL surgery, a thorough evaluation is essential to assess the need for the procedure. This evaluation involves a comprehensive assessment of the patient’s symptoms, physical examination, and imaging studies.

To evaluate the position and size of the previous ACL reconstruction graft tunnels, imaging techniques such as long leg alignment x-rays, varus/valgus stress x-rays, Rosenberg view, and MRI scans are commonly used. These imaging studies provide valuable information about the status of the meniscus and articular cartilage, as well as the presence of any concurrent knee injuries.

In addition to imaging, a thorough physical examination is necessary to assess secondary restraints and knee stability. The surgeon will evaluate the patient’s range of motion, joint stability, and any signs of instability or pain.

It is important to note that the evaluation process for revision ACL surgery may be more extensive compared to the initial ACL reconstruction. This is because the surgeon needs to carefully assess the reasons for the previous surgery’s failure and determine the most appropriate course of action.

As the evaluation process for revision ACL surgery is crucial in determining the appropriate course of action, patients can expect their surgeon to conduct a thorough assessment to ensure the best possible outcome.

Surgical Techniques for Revision ACL Reconstruction

When it comes to revision ACL reconstruction, there are several surgical techniques that can be employed. The choice of technique depends on various factors, including the patient’s age, activity level, and the condition of the remaining tissue. Here are some of the surgical options commonly used:

1. Autograft Options:

Autografts involve using the patient’s own tissue for the ACL reconstruction. The most commonly used autografts for revision surgery include:

• Patellar Tendon: This is a strong graft option that provides stability and durability.
• Quadriceps Tendon: The quadriceps tendon can be used as an alternative to the patellar tendon, especially in patients with previous patellar tendon graft.
• Hamstring Tendon: Harvesting hamstring tendons can be effective, especially in patients who have not used their hamstring tendons in previous surgeries.

2. Allograft Options:

Allografts involve using tissue from a donor to reconstruct the ACL. This can be a viable option for patients who do not have suitable autograft tissue available or prefer not to use their own tissue. Common allograft options include:

• Achilles Tendon: The Achilles tendon offers good strength and is often used as an allograft option.
• Hamstring Tendon: Allografts from the hamstring tendon can also be used in revision ACL reconstruction.

3. Bone Grafting:

In some cases, bone grafting may be necessary before proceeding with the revision ACL reconstruction. Bone grafting involves filling the previous graft tunnels with bone to provide a stable foundation for the new graft. This technique helps to improve the chances of a successful revision surgery.

4. Additional Procedures:

During revision ACL surgery, additional procedures may be performed to address concurrent knee injuries or complications. These procedures can include meniscal repairs or reconstructions to restore knee stability and function.

It is important to consult with an experienced orthopedic surgeon who can assess your specific case and recommend the most appropriate surgical technique for your revision ACL reconstruction.

Often extra stabilising procedures are incorporated to help give better stability eg Anterolateral ligament reconstruction, which is dione at the same time.

The rehabilitation after revision surgery is also often slower than after standard ACL surgery, with crutches being used for longer and sometimes a brace also.

Recovery and Rehabilitation After Revision ACL Surgery
