ACL Reconstruction

(figure 1)

 

The ACL (Anterior Cruciate Ligament) is one of the four main ligaments in the knee (figure 1). The ACL provides rotational stability and support to help prevent unnatural movement in the joint. High impact activities that feature rapid, twisting movements place extreme forces on the knees, which can lead to injury. Basketball, football, and skiing are common activities that can tear or damage an ACL, resulting in a loss of stability in the knee. ACL reconstruction is the most common form of treatment for patients who require the use of a stable knee for athletic sports, walking, or other low-impact activities


The Procedure
To reconstruct your ACL, Dr. LaDouceur uses the Bone Mulch™ Screw and WasherLoc™ Device (figure 1). These implants potentially enable
Dr. LaDouceur to reconstruct an extremely strong ACL, which may enable you to return to your active sports and recreational activities.
Typically, there are two options available when reconstructing the ACL. The new ligament material (graft) can be taken from one of your own tendons (autograft), or the graft can be taken from a tendon in the knee of a tissue donor (allograft).
The reconstruction is performed arthroscopically, which uses tiny incisions to insert surgical tools and cameras into the knee joint. A small tunnel is drilled into the femur (thighbone) and tibia (shinbone). The graft is then fed into the tunnel, looped over the Arthrotek® Bone Mulch™ Screw, and attached to the tibia using the Arthrotek® WasherLoc™ Device. The entire procedure usually requires 1–2 hours to complete and is performed while you are under anesthesia.

Joint Replacement and You
Each year, 43 million Americans are affected by arthritis. Osteoarthritis and rheumatoid arthritis are the two most common forms, which destroy the lubricating tissue found at the ends of all moving bones. This tissue, called cartilage, helps the joints to move freely and painlessly. However, when the cartilage is destroyed, bone painfully rubs against bone. To relieve the pain, surgeons can use implants that resurface or replace the damaged bone to restore movement and function. The joints most often replaced are the hips, knees, and shoulders.

Knee Replacement

Dr. LaDouceur performs knee replacement using the Ascent® knee system. The technique of knee replacement uses implants to resurface damaged bone and cartilage at the end of the thighbone and the top of the shinbone. Total knee implants are designed to enable you to regain function in your knee. Stair climbing, rising from a seat, and walking can be restored, while pain can be significantly decreased or completely eliminated. In Dr. LaDouceur’s hands, the Ascent® knee can help you return to a more active lifestyle.


Hip Replacement

Dr. LaDouceur performs hip replacement surgery using press-fit implants. Press-fit implants, unlike cemented implants, are designed to allow bone tissue to grow into the implant’s porous coating. This process is called bony in-growth and can potentially provide an extremely stable joint replacement for increased longevity and decreased pain.
Press-fit hip implants are made from titanium alloy.
Titanium alloy is also more flexible than other implant alloys, which helps transfer stress to your thighbone. The ability of your implant to
efficiently transfer normal weight-bearing stress to your thighbone can potentially increase your implant’s stability and longevity.


Shoulder Replacement


The Bio-Modular® total shoulder replacement uses modular components that allow Dr. LaDouceur to select the most appropriately sized implant. This option may enable him to better re-create the normal length of your humerus (upper arm bone), which is important in tensioning the soft tissues and providing maximum postoperative function.

Knee Replacements Designed for Women

As Boomers are aging, they are more frequently seeking relief from joint pain that is no longer manageable with over the counter medications, rest and heating pads.  Many are getting their knee, hip, or shoulder joints replaced. Some estimates indicate nearly 300,000 who undergo knee replacement surgery this year alone will be women.

The anatomy of a woman’s knee is very different from a man’s. Today, there is an implant company (Zimmer), which offers an enhanced joint technology –gender specific knee joint replacement –especially designed for a woman’s small frame. 

“This new knee was developed to be shaped and sized to fit the female anatomy,” Dr. LaDouceur said.  “Equally important, the gender series doubles the number of size options available, which allows for a better fit in all patients regardless of gender.”  There have been instances where the “female” knee has fit better in a male patient and vice versa.  The new gender specific joint accommodates the smaller female anatomy because it is thinner in profile, allows for natural movement and features a contour shape to provide a more precise fit for the narrower anatomy of a woman’s knee.

The goal of any joint replacement surgery is to improve an individual’s quality of life.  This includes alleviating pain, restoring mobility and improving function.  Along with the development of these new implants, there have also been improvements in instrumentation which permits a less invasive surgical technique.  All of these advancements typically result in smaller incisions, shorter hospital stays and quicker recovery.

If you are experiencing joint pain that is no longer relieved with home remedies, it might be time to consult a physician to get a full evaluation of the source of the pain and to determine if joint replacement surgery will give back the possibility to live life without pain. 

“Choosing joint replacement surgery is a highly individualized decision,” said Dr. LaDouceur.  “Patients, particularly younger or more active patients, need to weigh the advantages and disadvantages of having surgery.”  Dr. LaDouceur said the decision point often comes when pain and diminished quality of life become unacceptable and that threshold is different for each patient.

Patients report significantly less pain after surgery than before, and, in most cases, patients experience a markedly improved level of mobility compared to their preoperative condition. Many total joint patients suffer from other medical problems such as high blood pressure, heart disease and diabetes. The combination of pain reduction and improved mobility allow these patients to be involved in a regular exercise program, which has been shown to help reduce the risks of these other problems. “I have a number of patients that have been able to reduce or eliminate some medications as a direct consequence of joint replacement,” Dr. LaDouceur stated.

Studies show that regardless of which implant is used, about 90 percent of knee replacement surgeries are successful.  As implant design and materials improve, some studies suggest that 80 percent of replacements may last up to 20 years.
