What is ACL Preserving Total Knee Replacement?
ACL preserving total knee replacement is an advanced surgery performed by Dr. Jeffrey DeClaire to replace a damaged knee joint with a prosthesis while preserving the anterior cruciate ligament. It 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
This procedure offers better knee movement and stability for patients who wish to continue active lifestyles. It 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 even if it was healthy. However, due to the loss of the ACL, some patients experience knee instability. This surgery can improve knee function and strength after total knee replacement. The advantages 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?
Dr. DeClaire may order some blood tests before the surgery. Please inform our team 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.
New Implants for ACL Preserving Total Knee Replacement
Dr. DeClaire will select one of the new implant designs that facilitate the replacement of the damaged part of your knee without removing the ACL.
How is ACL Preserving Total Knee Replacement Performed?
- At Michigan Knee Institute we use advanced imaging techniques to prepare a specific plan based on your knee’s alignment and anatomy.
- General anesthesia or spinal anesthesia is given.
- A small incision is made at the front of your knee.
- Removal of the damaged part of the bone, taking care to retain the ligament.
- Specialized cutting guides are used to prepare the bone for the placement of an implant.
- The implant is carefully placed, and your surgeon checks for the correct movement of your knee.
- The incision is closed and covered with a surgical dressing.
Recovery after ACL Preserving Total Knee Replacement
Physical therapy, recommended by Dr. DeClaire, will be initiated on the same day as the surgery. Starting with passive range of motion exercises, progressing to active range of motion and knee strengthening exercises. You should be able to return to routine activities in 4-6 months.
Risks of ACL Preserving Total Knee Replacement
ACL preserving total knee replacement is a very safe procedure. However, there is a minimal risk of complications that include but are not limited to infection, bleeding, delayed healing, and failure of the implant.
