Recent advancements in orthopaedic surgical techniques have introduced avant-garde solutions to enhance outcomes for patients undergoing ACL reconstruction. One such innovation is the use of an internal brace to provide support to the reconstructed ligament during the healing process.
This article addresses common questions about using an internal brace for ACL reconstruction to help patients better understand its applications, risks, and long-term benefits.
Is the internal brace suitable for all ACL injuries?
The internal brace is most effective in cases where the ACL injury is acute and the ligament quality is sufficient to support augmentation. It is also indicated for patients who engage in physically demanding activities that place significant stress on the knee, such as professional athletes.
Your orthopaedic knee surgeon will evaluate the specifics of your injury and your individual circumstances, including age, activity level, and overall knee health before determining whether this technique is suitable for you.
What is involved in the internal brace technique in ACL reconstruction?
The internal brace is a synthetic ligament augmentation system designed to work alongside the natural graft used in ACL reconstruction, facilitating a quicker return to activities while maintaining the integrity of the reconstructed ligament.
During the surgery, the damaged ACL is either removed or repaired, depending on the injury's specifics. A graft, typically harvested from your hamstring or patellar tendon, is prepared and secured to replace the torn ligament.
The internal brace is then anchored at both ends, often using small bioabsorbable screws, alongside the graft. This dual-support system will ensure the knee is stabilised during the early stages of healing, reducing the risk of re-injury.
Are there any risks associated with using an internal brace?
As with any surgical intervention, there are potential risks associated with using an internal brace in ACL reconstruction. However, the risks are generally considered low.
One possible risk is irritation or discomfort caused by the internal brace’s fixation points. Although rare, some patients may experience localised inflammation or pain at the anchoring sites.
Other general surgical risks, such as infection, bleeding, or stiffness in the knee joint, apply to the surgery but aren’t specific to the internal brace itself.
How does the internal brace affect the long-term durability of the ACL reconstruction?
One of the significant advantages of using an internal brace in ACL reconstruction is its potential to enhance the long-term durability of the reconstructed ligament. By offloading stress from the graft, the internal brace allows the biological tissue to heal more effectively and reduces the likelihood of graft failure.
Studies have also shown that the internal brace can help maintain knee stability even during high-impact activities. Furthermore, the internal brace acts as a safety net in cases where the graft may otherwise be at risk of re-tearing.
In the long term, patients who undergo ACL reconstruction with an internal brace often report higher levels of confidence in their knee’s stability, which translates to improved performance in physical activities and a lower risk of secondary injuries.
