Obesity a factor in failed knee replacements

My brother-in-law is very overweight. His knees are bad but he refuses to lose weight. He says he’ll just have them replaced when they wear out. Is it really that simple?

The rising cost of health care has taken “simple” out of almost every picture today. Obesity is linked with degenerative disease of the hips and knees. A high body weight is also linked to a poor result after the joints are replaced.

A recent study at The Good Samaritan Hospital in Baltimore, Maryland compared total knee replacements (TKRs) in obese and nonobese adults. The patients all got the same joint implant (one that has been used successfully for many years).

Results were reviewed after five years. Being overweight had a negative impact on the success rate of TKRs. More implants failed in the obese group than in the nonobese group. Obese patients with failed implants had lower satisfaction rates.

There are improved medical treatments for obesity today. Encourage your brother-in-law to see his doctor and find out what are his options. He may be able to at least improve his health before his knees wear out and he faces the risks of surgery.

One leg shorter than other as a result of hip replacement?

A year ago I had a total hip replacement. I did all my exercises and I’m almost back to normal. There is one problem. It feels like that leg is longer than my other leg. Is this possible or am I just imagining it?

You may be quite right. In a small number of patients after total hip replacement the leg either is longer or seems longer. An X-ray and exam are needed to find out for sure.

If the leg is truly longer than the other one, the doctor will see this on X-ray. Sometimes this can happen because of the implant. Usually the patient has pain along the outside of the hip or around the incision. The pelvis drops on the short side to make up the difference. A shoe lift may be all that’s needed.

If the legs are truly equal in length on X-ray then the problem is considered called a functional leg length difference. This means the soft tissues around the hip are tight or off-balance pulling the leg up or down. In these cases physical therapy may be helpful. An aggressive program of stretching and/or strengthening may restore limb length and function.

Make an appointment today with your orthopedic surgeon for a follow-up visit. This kind of problem should be addressed sooner than later.

Partial vs. total shoulder replacement

I have severe pain and limited motion in my left shoulder. My problems all come from arthritis. My doctor thinks I should have a partial shoulder replacement. If the arthritis gets worse I can always have a total replacement later. Does it really work that way?
Many doctors hold to this idea. A recent review of the studies on partial (hemiarthroplasty) versus total shoulder replacements might call that plan into question.

Some studies show that even with a hemiarthroplasty the surface of the shoulder socket continues to wear down and deteriorate. Then when it’s time to convert to a total shoulder, there isn’t enough good, solid bone for the implant.

On the other hand, starting with a total shoulder arthroplasty (TSA) leaves the patient with no place to go if problems occur. There isn’t a good replacement for the replacement.

Overall the studies done comparing hemiarthroplasty to a TSA show the TSA gives patients better function over a longer period of time. More studies are needed to fully compare these two treatment options.

Exercising on your own after total knee replacement surgery

I had a total knee replacement six months ago. After physical therapy in the hospital, I had more therapy at home. Now I’m doing my own exercises everyday. How long should I keep this up?

It might be time for a follow-up visit with your doctor or therapist. Tests of motion, strength, balance, and coordination can guide you. Patients exercising on their own can still show major weakness even years after a total knee replacement. This can put you at risk for falls and other injuries.

Every person is different and has his or her own unique needs for rehab after joint replacement. A closer look at what you’re doing and how you doing can lead to an answer to your question.

It’s likely that some form of exercise will be advised. Regular exercise and physical activity has been shown to keep joints healthy, even joints already affected by arthritis. Make it worth your while to exercise. Find out what’s best for you in this phase of your recovery.

Could soccer playing wear out my hip?

I’m 45-years old and need a hip replacement because of arthritis. I played soccer from the time I was in pre-school all the way through college. Even as an adult I played on coed rec teams. Could the soccer playing wear my hip out?

Playing soccer may not be the issue. Studies show it’s the sports injuries players get that increase the risk of osteoarthritis. Ankle and knee injuries are common among soccer players. Since these two joints are in a direct line-up with the hip, it makes sense that such injuries can lead to arthritis later.

Another risk factor for injury and thus arthritis is left-leg dominance. At this point we know more about what isn’t a risk than what is. In studies of soccer players ages 12 to 18, there was no apparent increase in risk of injury linked with body size or type, balance, strength, or flexibility. Preseason play didn’t seem to make a difference either.

Is it ever too late for surgery to repair torn rotator cuff?

I have a large rotator cuff tear in my left shoulder. I’ve been putting off surgery and trying everything else first. I’m ready to throw the towel in and have the surgery. How do you know when it’s too late for an operation to help?

There’s nothing wrong with trying conservative care before going for a rotator cuff repair. In some cases, anti-inflammatory drugs help. In other cases, cortisone injections or physical therapy can make a difference.

But for patients who still have pain, loss of motion, and reduced function, surgery may be the best option. Many patients put it off for months and even years. They still report a good result after the operation.

New methods using arthroscopic surgery and tiny incisions have changed the results of this operation. Even full-thickness tears or tendons that have retracted far away from the place where they normally attach can have a good outcome.

Source of knee pain best discovered by MRI

I am only 48 years old, but I have severe knee pain from years of running marathons and participating in triathlons. The first doctor I saw took an X-ray and said there’s some narrowing of the joint space, but nothing to worry about. Would an MRI (magnetic resonance imaging) show anything else the X-ray didn’t show?

For years doctors have used X-rays to help diagnose osteoarthritis (OA). Recently, researchers have started to call this practice into question. An X-ray reading of the joint may not be valid in predicting pain and function. In other words, the joint looks fine but the pain is very limiting all the same.

More and more doctors are using MRIs to find OA. MRIs can image cartilage and soft tissues. The more the doctor knows about the soft tissues involved, the more direct and specific treatment can be.

Ask your doctor about having an MRI. You may be a good candidate.

MRA more accurate than MRI for ddetermining cause of hip pain

What is magnetic resonance arthrography (MRA)? I’ve heard of MRI but not MRA. My doctor wants me to have an MRA to help figure out what’s wrong with my hip.

Magnetic resonance imaging (MRI) and magnetic resonance arthrography (MRA) are very similar tools. MRA is basically MRI for the joints. It is more accurate in detecting joint problems. MRI can confirm there’s a problem in the joint. MRA shows exactly what is the abnormality.

CT scans work well for bone lesions around the hip. CT scan shows places where the bone might have a tumor, abnormal anatomy, or necrosis (dead cells).

If you ever need surgery on the hip, advanced imaging studies of this type are very important. The more details the surgeon can see ahead of time, the better the surgical plan with no (or very few) last minute surprises.

Shoulder pain caused by bone spurs

What is calcific tendinitis? My mother had an X-ray and this is what they found that’s causing her shoulder pain.

Calcific tendinitis or bone spurs occur when calcium deposits around the shoulder cause pain. The deposits occur most often in the supraspinatus tendon that goes across the top of the shoulder.

The pain is unrelated to shoulder position or activity. Adults between the ages of 30 and 50 are affected most often.

It’s not clear what causes this problem. Scientists aren’t sure if it’s an inflammatory response or caused by tendon injury. Many people have calcific tendinitis without any symptoms.

Others have severe pain made worse by even the slightest shoulder movement. The size of the deposit doesn’t seem to predict the amount of pain.

Is a nerve block safe for total knee replacement surgery?

I’m going to have a total knee replacement next week. The doctor asked me if I want a nerve block before the operation to help stop the pain after the operation. What are the chances of ending up with permanent nerve damage from this?

It’s possible but not likely. Studies show permanent nerve damage after nerve blocks is very low. In fact when nerve damage occurs, most patients recover completely within three months’ time. Minor long-term problems can occur such as mild muscle weakness or a small patch of numbness.

Ask your doctor what his or her experience has been using nerve blocks. Find out what other problems can occur and how often this happens. Consider the benefits of a preoperative nerve block: less pain and less use of morphine or other painkillers after the operation.

Studies show a single-injection femoral nerve block is a simple and safe way to reduce pain after total knee replacement.
