What is ACL Preserving Total Knee Replacement?
ACL preserving total knee replacement is an advanced surgery performed to replace a damaged knee joint with a prosthesis while preserving the anterior cruciate ligament (ACL). The ACL is a crucial ligament that runs diagonally across the front of the knee and provides rotational knee stability.
Indication for ACL Preserving Total Knee Replacement
ACL preserving total knee replacement offers better knee movement and stability for patients who wish to continue active lifestyles. This procedure allows patients to continue to play sports, which requires bending, twisting, and making abrupt changes in direction.
Advantages of ACL Preserving Total Knee Replacement
Traditionally, surgery for total knee replacement involved removing the anterior cruciate ligament (ACL) even if it was healthy. However, due to the loss of the ACL, some patients experience knee instability. ACL preserving during surgery can improve knee function and strength after total knee replacement. The advantages of ACL preservation include:
- Good range of motion
- Better functioning of the implant
- Prolongs the life of the implant
- Gives a natural feel to the knee
How do you prepare for ACL Preserving Total Knee Replacement?
Your doctor may order some blood tests before the surgery. Please inform your doctor about the various medications you are taking, as they may have to be stopped for a few days before surgery. It would be best if you also had someone take you home after surgery and help you with daily activities for a few days.
