What is double-bundle ACL reconstruction?
The double-bundle procedure requires two additional bone tunnels to accommodate a second graft and one additional incision. The surgical procedure may take slightly longer, although surgeons performing this procedure routinely can perform it in a similar manner to a single bundle ACL reconstruction.
Is the ACL a double-bundle ligament?
The ACL has two bundles, anteromedial and posterolateral, the names given from the tibial insertion site.
What are the 2 bundles of the ACL?
The anterior cruciate ligament (ACL) consists of two major fiber bundles, namely the anteromedial and posterolateral bundle. When the knee is extended, the posterolateral bundle (PL) is tight and the anteromedial (AM) bundle is moderately lax.
What is single bundle and double-bundle ACL reconstruction?
In single-bundle reconstruction, one of these bundles is restored whereas in double-bundle reconstruction, both are restored. Double-bundle reconstruction may give greater knee stability but is more technically demanding and invasive than single-bundle reconstruction.
What is the best ACL surgery for athletes?
Patellar Tendon It is the graft with the longest track record and is consider by many to be the “gold-standard” for ACL reconstruction. In most circumstances this is the graft recommended for professional athletes and in any young active individual.
Which screw is better for ACL surgery?
BACKGROUND: Graft fixation during anterior cruciate ligament (ACL) reconstruction can be achieved with use of either bioabsorbable screws or metal screws. Although bioabsorbable screws and metal screws have similar fixation strengths, bioabsorbable screws eliminate the need for removal.
What is single-bundle ACL reconstruction?
Procedure: Anatomic Single-Bundle ACL Reconstruction. Surgical reconstruction of the ACL using a single autograft quadriceps tendon with a bone block. The free end of the graft is not split. The bone block is placed in a single femoral tunnel located in the center of the femoral ACL insertion site.
What is a single-bundle ACL?
Just as the term indicates, single-bundle is a piece of tendon taken from elsewhere around the knee (usually patellar tendon or hamstrings) and used to replace the deficient ACL. A double-bundle graft is more likely made from hamstring material.
Which ACL bundle is tight in extension?
posterolateral bundle
The anterior cruciate ligament (ACL) consists of two major fiber bundles, namely the anteromedial and posterolateral bundle. When the knee is extended, the posterolateral bundle (PL) is tight and the anteromedial (AM) bundle is moderately lax.
Which bundle of the ACL is bigger?
anteromedial bundle
The anterior cruciate ligament (ACL) consists of 2 bundles: a slightly larger anteromedial bundle and a posterolateral bundle, named according to their relative tibial insertion sites. Both bundles are crucial to knee stability.
What is the most successful ACL surgery?
The patellar tendon graft (PTG) has always been the gold standard for anterior cruciate ligament (ACL) reconstruction.
Which ACL graft is strongest?
The strongest option is the BTB graft. The graft incorporates more solid into the bone due to the bone plugs on either end of the tendon. However, BTB grafts have been known to have the slowest recovery time when it comes to meeting rehab milestones and returning to sport.
How long do ACL screws last?
However, the evidence on the use of biodegradable interference screws in anterior cruciate ligament (ACL) reconstruction is still scarce. Although the screws promise to degrade within approximately 12-24 months after surgery, several cases have been reported in which this did not happen [1, 10, 15].
Do all ACL surgeries require screws?
Abstract. BACKGROUND: Graft fixation during anterior cruciate ligament (ACL) reconstruction can be achieved with use of either bioabsorbable screws or metal screws. Although bioabsorbable screws and metal screws have similar fixation strengths, bioabsorbable screws eliminate the need for removal.
Can you have ACL surgery on both knees?
There were no major complications in either group. Both groups had strong, stable knees after ACL reconstruction. The cost analysis of bilateral surgery showed a large costs savings to patients with injured ACLs in both knees. Doing bilateral surgery cost 7,500 dollars less for each patient.
Which bundle is more protected when the knee is extended?
While the anteromedial bundle is the primary restraint against anterior tibial translation, the posterolateral bundle tends to stabilize the knee near full extension, particularly against rotatory loads.
What are the top 4 choices for ACL grafts?
The main options available consist of allografts and autografts, which include patellar tendon, hamstring tendon, and quadriceps tendon autografts.
Which ACL reconstruction method is best?
The patellar tendon graft (PTG) has always been the gold standard for anterior cruciate ligament (ACL) reconstruction. Yet, most orthopedic surgeons prefer hamstring grafts for younger athletes and cadaver grafts for older patients.
What is the weakest ACL graft?
The graft complex is actually at its weakest at around the 6 week post operative mark.
What is a double bundle ACL surgery?
The double-bundle procedure requires two additional bone tunnels to accommodate a second graft and one additional incision. The surgical procedure may take slightly longer, although surgeons performing this procedure routinely can perform it in a similar manner to a single bundle ACL reconstruction.
What is involved in ACL reconstruction?
Reconstruction of the ligament should focus on restoration of the native functional and anatomical properties and should take the size, shape and orientation of the ACL into account.
When can a single bundle procedure be performed as a double bundle?
When indications and contraindications for the technique used are based on native anatomical characteristics, either a single-bundle or a double-bundle procedure can be performed according to the same double-bundle concept. Publication types Review MeSH terms
How many bundles of fibers are in the ACL?
The ligament itself is made of thousands of individual fibers, that together form the ACL. Some of these fibers are organized into distinct bundles. The normal ACL has two primary bundles of fibers. These bundles are positioned closely together, in some patients with normal ACLs it can be difficult to discern distinct bundles.
