How old is too old for a total knee replacement?

February 19, 2010 — admin

My 92-year old mother has severe knee arthritis. It seems to me she could sure benefit from a knee replacement. Is she too old?

Maybe not! A recent study from Mayo Clinic reports good results for adults over age 90 getting their first total knee replacement (TKR). They also report on patients ages 90 to 102 who had a repair or replacement of a previous TKR.

Doctors are expecting to see more and more adults in their 90s (and older) outliving the TKR put in when they were in their 70s. Likewise, as more people live longer, first timers in need of a joint replacement may show up in their 90s.

Is Grandma too old for total hip replacement?

February 5, 2010 — admin

My 83-year old grandma is going to have a total hip replacement. We’re all worried that she’s too old for this. What do you think?

Americans are living longer and in better health. This means they are more likely to need a major joint replacement as they reach their 80s. Joint replacements are available for the shoulder, hip, or knee.

These operations do put older adults at increased risk of problems.

Studies of 80-year old (and older) adults compared to younger adults show there is an increase in the number of serious problems that occur. But the overall rate is low, and it’s more likely to happen in elderly patients with other health problems.

Results should be good if your grandmother is in good health and the doctor has approved the surgery.

Knee surgery video reveals lots of tools in use, but how?

February 3, 2010 — admin

I had some pretty fancy surgery done last week inside my knee joint. The doctor gave me a video of the entire operation. What I can’t figure out is how they got all those tools I saw on the video inside my knee. What can you tell me?

It sounds like your surgeon used an arthroscope to enter the joint. This long, slender tool pokes through the skin and tissue right into the knee joint. A tiny TV camera on the end allows the physician to see inside the joint.

There’s a special part of the arthroscope called a cannula. The cannula can be a rigid or flexible tube. It’s used to drain fluid or guide other instruments into the joint.

New tools have been made for arthroscopic surgery. There are forceps, shavers, measuring rods, and even tiny drills that can pass through the cannula. Once inside, the doctor uses special foot pedals and hand held devices to guide the camera and operate the tools. Frayed tissue can be shaved smooth. Torn cartilage can be sewn or glued back down. Bone chips can be removed and so on.

You can watch a total knee replacement surgery and get more information on Dr. Zehr’s Web site.

Will I be able to climb stairs after my total knee replacement?

January 21, 2010 — admin

I had a total knee replacement five months ago. I can walk just fine, but I still can’t climb the two stairs in front of my house. Will I ever be able to do this?

Stair climbing is a difficult skill for many people who have had total knee replacement. This is true even one year after surgery. After surgery, the support from leg muscles is only one-third of the strength and force needed to climb stairs.

Bring your concern to your doctor’s attention. A physical therapist can help you begin an exercise program specifically designed to assist you with stairs. If you saw a physical therapist during your recovery from surgery, do not hesitate to contact the therapist and request additional services.

Did I waste $2,000 on a CPM machine? Does it help after knee replacement?

September 1, 2009 — admin
Last year I spent $2,000 purchasing a continuous passive motion machine to use after a total knee replacement. I was planning to resell it. Now I find out the latest studies say it doesn’t work. What’s this all about?

 
Continuous passive motion (CPM) was first used in the 1980s when a well-known orthopedic surgeon did some studies with it to help joints heal after fractures. It’s use after total knee replacement has been debated for years.

Some studies show CPM helps patients get more motion back faster. Others say it doesn’t make a difference. Some studies show a shorter hospital stay for patients using CPM. Others don’t show any difference at all.

Researchers suggest different study designs and methods of research may explain these varied results. For example, in one study the CPM was only used for 24 hours after the operation. Another study used it for three hours twice a day for five days.

Sample size (the number of patients in the study) can make a difference in results, too. Smaller studies may not be as valid as larger studies. Finally surgery has improved over the years making the use of CPM less necessary. Patients are already able to move freely after the operation with fewer muscles cut and less swelling. They don’t need a machine to passively bend and straighten the knee for them.
