What are the activity limits after rotator cuff surgery?

July 30th — admin

I’m in the early weeks of recovery from surgery for a rotator cuff tear. Just how much activity can the repair take? I’d like to know what are the limits.

Each surgical repair is different based on a few factors. First is the size of the tear and the method used to repair it. Second is the timing. You mentioned being in the early weeks of recovery. The amount of load the repair can handle increases as the tissue heals. In the first six weeks the load limits are much less than after six to eight weeks.

For example the load on the repair is much less with forward flexion of the arm compared to other shoulder movements. Passive motion (someone else moves the arm) versus active movement (you move the arm) has different load limits.

Your surgeon should have given you some idea of the limits both in terms of motion and lifting. Sometimes patients don’t realize the paperwork they take home with them has this information in it. Read everything given to you. Contact your surgeon directly if you don’t find what you are looking for.

Surgery on torn ACL may be needed to protect the joint

July 29th — admin

My 21-year old daughter hurt her knee when she slipped and fell on some ice. The doctor says the ACL is torn and she needs surgery to protect the joint. Protect it from what?

There are some studies that show patients are at greater risk for knee re-injury after anterior cruciate ligament (ACL) tears if the damage isn’t repaired. The most common injuries later are meniscus and joint cartilage tears.

If the joint cartilage is damaged, the bone underneath is unprotected. Wear and tear can cause damage to the bone. Painful arthritis can develop much later.

A recent study of over 6,000 adults confirmed these beliefs. Patients who didn’t have an ACL repair and opted for conservative care were twice as likely to injure the meniscus later and 30 percent more likely to damage the joint cartilage.

Careful monitoring needed for hip dysplasia

July 28th — admin

I just came back from the doctor’s where I found out I have hip dysplasia. My hip started hurting about six months ago and the X-rays showed this deformity. How often does this happen, and what does it mean in the long-run?

Developmental hip dysplasia (DDH) is probably present at birth or occurs during development in the early years. A change in the normal anatomy results in a shallow hip socket. The angle or tilt of the femur (thigh bone) and rotation of the femoral shaft (long part of the bone) are also different from normal. The patient is at increased risk of partial dislocation called subluxation or even full dislocation.

According to at least one study, this condition occurs in about five to 13 percent of the adult population. The person may not even know it’s there until pain sends him or her to the doctor for an X-ray.

There is some evidence that dysplastic hips have an uneven load across the joint. The cartilage on the surface of the joint can get damaged directly. Abnormal stresses on the soft tissues supporting the joint can lead to wear and tear of ligaments and cartilage.

Damage to the cartilage around the rim of the socket changes the pressure inside the joint. Synovial fluid that lubricates the joint may leak out adding to the wearing away of the cartilage.

No one is quite sure if these changes always occur or how long it takes before they result in arthritis. One study from Denmark reported no adverse changes even after 10 years of untreated DDH. It may be best to treat the hip conservatively but keep contact with your doctor. Any change in symptoms should be re-evaluated sooner than later to prevent excessive damage.

No shoulder surgery needed for teenage football player

July 27th — admin

My 17-year old son separated his shoulder playing football. The doctors say ‘no surgery’ just rest and let it heal on its own. Could he get back to playing football sooner with an operation?

There are lots of problems with operations trying to repair the AC (acromioclavicular) joint. In fact more than 60 different ways to surgically repair the AC joint have been tried.

Wires and screws don’t seem to hold. They break or move causing problems. Sutures to hold the joint together don’t seem strong enough. Many times the joint starts to move apart again.

Surgery isn’t an option unless the person doesn’t recover with conservative care or the injury is so severe an operation is the only way to treat it.

If your son follows his doctor’s instructions he should heal in two to six weeks. Rehab should be completed before resuming football to prevent re-injury.

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.

Can you get arthritis in a joint replacement?

July 23rd — admin

Have you ever heard of getting arthritis in a joint replacement? That’s what my doctor tells me is causing my hip pain. How is that possible?

Prosthetic arthritis is a very real condition. It is caused by erosion or damage to the joint cartilage. This type of problem occurs with a joint implant called a unipolar hemiarthroplasty.

The unipolar implant is one of the first type of partial hip replacements designed. It replaces the round head of the femur (thigh bone). It has a stem attached to it that goes down inside the shaft of the femur to hold it in place.

Younger, more active patients are more likely to develop this kind of problem. The implant moving inside the hip socket chips away small pieces of bone and cartilage leading to cartilage erosion also known as prosthetic arthritis.

A newer type of implant was made to try and avoid this problem. It’s called the bipolar prosthesis. Besides the femoral implant, a plastic-lined, metal cup is inserted into the patient’s own natural acetabulum (hip socket). Instead of just the femoral head moving in the acetabulum (unipolar implant), the bipolar allows for two points of motion. The femoral head moves and rotates inside the cup and the cup moves and rotates inside the acetabulum.

The bipolar hemiarthroplasty is more expensive but recommended for active patients younger than 65.

MRI or MRA to diagnose rotator cuff tear?

July 22nd — admin

I’m going to be seeing the doctor for a shoulder exam. I’m pretty sure I have a torn rotator cuff. Should I ask for an MRI?

Your surgeon will know the best tests to order based on your history and the examination. MRIs give good contrast of the soft tissues. It’s an ideal way to see inside the joint without actually opening it up.

MRIs are only 84 to 96 percent accurate in finding rotator cuff tears (RCT). Magnetic Resonance Arthrography (MRA) may be a better choice if a RCT is suspected.

MRA uses the natural fluid in the joint as a way to look for “holes” in the capsule from a RCT. A contrasting agent is injected into the joint. Any fluid that shows up outside the capsule must have moved through the defect.

MRA isn’t available everywhere. Ask your surgeon if it’s available in your area and if it’s recommended for your situation.

Do you need resurfacing before knee joint replacement?

July 21st — admin

What is selective resurfacing? I know it has something to do with knee joint replacements.

The knee joint consists of three parts: the knee cap (patella), the femur (thigh bone), and the tibia (lower leg bone). A knee joint replacement is done when arthritic changes cause pain, swelling, and loss of knee function.

Arthritic changes occur inside the knee joint as well as behind the patella. The patella may need to be resurfaced for a successful joint replacement. This means a metal or plastic backing is added to the patella. This helps it ride smoothly over the other parts of the implant when the knee moves.

Not every patient needs patellar resurfacing. Doctors decide whether or not to do this when they look at the back of the patella during the operation. The doctor looks at the shape of the patella and the condition of the cartilage when making this decision.

Selective resurfacing refers to the fact that not all patients have the patella resurfaced, only those who need it based on the surgeon’s exam.

Snapping hip syndrome affects this ballerina

July 20th — admin

Whenever I lift my leg straight up in front or to the side, I feel (and I think I can hear) a snapping sound. It doesn’t hurt but it’s very annoying. I’m taking a ballet class and we use this movement often. What can cause this problem?

You may be experiencing a condition called snapping hip syndrome. In medical terms it’s called external coxa saltans. The sound is caused by the iliotibial band (ITB) sliding over a part of the hipbone called the greater trochanter.

The ITB is a long piece of fascia (a thick layer of connective tissue) attached at the top to a hip muscle. It goes from the hip all the way down to the outside edge of the knee.

In between the ITB and the greater trochanter is a small, round cushion called the trochanteric bursa. As the ITB rubs over the greater trochanter, the bursa tries to cushion the friction. But repeated snapping back and forth can cause inflammation of the bursa called bursitis. When bursitis occurs the patient has both snapping and pain.

The first step may be to ask your dance instructor to watch how you are doing the barre or floor exercises that cause snapping. There may be an acceptable way to change your form. Stretching the ITB may also help. Doing something now before a painful response begins is always a good idea!

No advice from friends on total shoulder replacement surgery

July 19th — admin

When I had my knee replaced many of my friends had already had this same operation. They gave me lots of advice and information. Now I’m getting ready for a shoulder replacement. I can’t find even one friend or relative who’s had this surgery. Are folks who have this done happy with the results?

It’s true that the number of hip and knee replacements far out pace the number of shoulder replacements. The number of shoulder replacements is increasing every year. Last year more than 10,000 were done in the United States.

Long-term studies 20 years down the road aren’t available yet. But short- to mid-term results are in. Most patients have a good result with decreased pain and improved movement. These two results also mean better function and higher quality of life for most people.

As with any surgery, problems can occur. In a small number of patients blood clots, infection, or fracture can cause death or delay recovery. The risk of technical difficulties is greater with shoulder replacement surgery compared to hip and knee.

Overall, patients report improved quality-of-life with a shoulder replacement. If they had to do it over again, they would have the same operation.
