Tissue grafts often used to repair torn ACL

July 26th — admin

I’m going to have an ACL repair using my own patellar tendon as the graft. What can you tell me about this kind of graft?

There are many different kinds of tissue grafts that can be used to repair a torn or ruptured anterior cruciate ligament (ACL). The bone-patellar tendon-bone (BPTB) is called the “gold standard.” It’s used the most with the best results.

The graft is made up of the middle third of the patellar tendon and a piece of bone on either end. The bone is taken at one end from the kneecap and at the other end from the lower leg bone (tibia).

This graft works well because the patellar tendon has a high strength and stiffness. The bone plugs make it possible to get a good solid hold with screws to keep it in place. The graft seems to take hold quickly.

There are a few problems with the BPTB. Some patients have pain and swelling where the graft is taken from. It can be very difficult to kneel. Other patients report numbness, most likely caused by damage to a branch of the saphenous nerve. Loss of quadriceps muscle strength and even fracture of the patella are also possible problems.

The best way to rehab a knee after ACL reconstruction surgery

May 21st — admin

What’s the best way to rehab my knee after an ACL reconstruction?

Most doctors will send you to a physical therapist who can guide you through this process. Exercises at the beginning of rehab are different from what your knee can handle later. The goal is to get as much motion back as possible without damaging the knee any further.

The healing graft is under increased strain when the knee is in the fully extended position. Closed kinetic chain exercises with the foot on the floor or other surface strain the ACL less when the hip is bent. An example of this activity would be the mini-squats often prescribed in the early phase of rehab.

High demand exercises such as the lunge can be done when the squat is deemed safe to do after ACL repair. Then comes the step-up, step-down, and sit to stand exercises. These can all done on one leg. Each one puts about the same amount of strain on the healing graft.

Is a return to sports six months after ACL reconstruction possible?

May 18th — admin

I’m scheduled to have an ACL reconstruction in two weeks. The doctor thinks I can get back to playing sports within six months. Will I have my full function by then?

There are many parts to recovery after ACL reconstruction. Rehab can move forward quickly if there aren’t any complications and the joint is mechanically stable. Your doctor and your physical therapist will help you know when the time is right to start each phase of your rehab program.

Studies show the joint’s sense of position, called proprioception, comes back slowly over the first nine to 12 months. Most rehab programs focus on balance and proprioception during this time. Strength training and flexibility are also important.

Agility training to restore functional stability comes in later phases of rehab. You probably won’t be 100 percent at six months but if all goes well, you’ll be safe to resume sports. Follow your doctor’s advice carefully for the best long-term results.

The best way to prevent ACL injuries

May 14th — admin

What’s the best way to prevent ACL injuries?

The jury is still out on this one. We can give you the results so far. Studies show balance and strength training are important. Flexibility is also a key feature in prevention programs. Training in all three of these areas is advised for the ankle, knee, and hip.

Single-leg balance drills have been shown to decrease knee injuries in female athletes. Forward and backward motion of the joint is improved with these exercises. Side-to-side motion is not as likely to change.

The results of studies so far suggest preseason training works well for athletes at risk for ACL injury. This includes female athletes with increased forward joint motion of the tibia (lower leg) against the femur (upper leg). Team training is good, but preventing injury works best by looking at each player’s needs and providing individual training.

Losee maneuver can detect ACL injury

March 24th — admin

What is the “Losee maneuver?” I’ve heard it can be used to detect a torn anterior cruciate ligament.

Dr. Ron Losee from Ennis, Montana, was the first to describe a test for ACL instability. It was called the Losee maneuver for many years. Now it’s sometimes referred to as the “pivot-shift” test.

When the test is done, the patient is asked, “Is this how your knee feels when it gives out?” The doctor doesn’t always feel a change in the knee during the test, so the patient’s report is important.

A positive pivot-shift may be a sign that surgery is needed to repair the torn ligament. There is a device that measures laxity between the two knees (a KT-2000). The results of one test usually aren’t enough to tell which patients need an operation. Tests like the pivot-shift, along with several others, are still important.

Surgery preferred for double-ligament knee injury

December 29th — admin

I frequently read in sports journals about the two main ligaments in the knee. I understand the anterior cruciate ligament is the one that’s most often injured. Is it possible to tear both ligaments at the same time?

Yes. High-velocity or high-energy accidents in contact sports can cause damage to both ligaments in the knee. This can also happen in car accidents if the knee impacts the dashboard. Injuring both ligaments makes the knee very unstable. This causes problems walking and using the knee.

With this much damage, surgery is the preferred treatment. The surgeon will repair as much as possible at one time, but these are time-consuming operations. Sometimes a second surgery is needed to finish the repair. The first and most important surgery is to repair the posterior cruciate ligament and surrounding structures. These must be repaired at the same time because these tissues work together to help stabilize the knee.

Is postponing surgery for torn ACL the right move?

December 15th — admin

I recently tore the anterior cruciate ligament in my right knee. The doctor told me I need surgery to repair the tear, but he seems to be in no hurry to operate. Shouldn’t this kind of surgery be done right away?

Your doctor may be waiting for the inflammation to calm down. When a ligament is torn or partially torn, the body responds immediately to help the healing process. Sometimes this results in a lot of swelling in the area, with a loss of knee motion.

Your doctor may have you start a physical therapy program before surgery. Physical therapy is used to help reduce pain and swelling and improve knee motion and strength. Once the initial healing reaction has calmed down and you have your motion back, surgery can be scheduled. Research shows improved results when ACL surgery is postponed until these goals are achieved.

Knee surgery vs. physical therapy for torn ACL

December 7th — admin

My skiing buddy and I both had knee injuries in competition last month. It turns out we had the same injury–a torn anterior cruciate ligament. He went on to have knee surgery. My doctor said my knee will get better with physical therapy. Shouldn’t I have the same treatment as my friend?

Not necessarily. It’s likely your friend’s ACL was severely damaged. Your doctor may have determined that your ligament was only mildly torn or stretched out. In that case, physical therapy treatments can be used to help improve your knee function.

Your doctor and physical therapist will watch to see if you get full knee motion and strength. If your pain and swelling go away and your knee feels stable and strong, you may be able to return to competition without knee surgery.

Feeling unsteady after knee surgery? This may be why.

December 2nd — admin

Six months ago, my doctor reconstructed my torn ACL using a piece of the tendon and bone from below my kneecap. I completed physical therapy and still feel like the knee isn’t going to hold me. My doctor says the surgery was a success and the knee is as “tight,” if not tighter, than before my injury. If that’s the case, why do I feel so unsteady on the leg?

There are several tests physicians use to check the integrity or strength of the repaired ligament. One of these is the pivot-shift test, in which the doctor applies pressure to the lower leg just below the knee. A “tight” joint will not shift or move with this test.

Your sense that the leg is not steady or stable enough to hold you may be caused by muscle weakness. When the replacement tissue for the torn ligament is taken from below the kneecap, the quadriceps muscle on the front of the thigh may lose strength. You may need some additional strengthening exercises. Contact your physical therapist for a follow-up evaluation.

What is ACL Reconstruction Surgery?

September 14th — admin
What is ACL reconstruction surgery? Where does the “reconstruction” come from?

 
The anterior cruciate ligament–or ACL–is a major stabilizer of the knee joint. When this ligament is torn, the original, damaged tendon is removed, and the knee is reconstructed with new tissue. Typically, surgeons cut a strip from the patellar tendon (below the knee) to replace the ACL. Or they may use tissue from one of the hamstring tendons along the inside of the thigh. Screws are used to attach the new tissue in the exact location of the original tendon. This procedure is typically successful. In a recent study of 200 patients, no significant medical complications developed from ACL reconstructions using the patellar tendon. In fact, 96 to 98 percent of patients said they would choose this surgery if they had to go back and do it again.
