New Knees Have Her Living Life to the Max!

"Dr Zehr did a bilateral knee replacement on me Feb. 15, 2010. We laughed and I told him I would be his poster child! Well, I just wanted to let you know that I have just been named North Carolina's Senior Female Tennis Player of the Year (2013).  

 

I am 69 years old (the rest of my body----not my knees).

Also, this coming September, I plan to ride my 1936 Indian Scout Motorcycle 4100 miles (from Daytona Beach, Florida to Tacoma, Washington) on the Cannonball Endurance Run - crossing the country in 16 days in an effort to raise money for the Colon Cancer Alliance (I am a colon cancer survivor).


I
will be 70, my motorcycle 78!

Life is good and I thank
Dr. Zehr for giving me a renewed chance to keep living it to the max!"

Headshot of Robert J. Zehr, MDSo many of you have encouraging, humorous and very inspiring stories to tell about your life after surgery by ZCO! I want to take a moment to thank you for replying to this newsletter with your testimonies or sending them to our office. We are constantly updating our website with them and adding to our "Wall of Fame" which is a continuous looping slideshow playing on large wall-mounted flat screen TVs in our lobby. And we feature one such story in each newsletter.

This month I want to share two aspects of Dottie Mattern's experience. She tells you in her own words (see the left column) about her successful surgical outcome for knee replacement. She also talks about her upcoming challenge ride this fall to raise money for colon cancer research. 

I get to know my patients quite well...but even I was surprised to see photos of some of Dottie's adventures - camel riding, bungee jumping, playing baseball with some famous folks and playing championship tennis. Some of them BKR (before knee replacement), some AKR (after knee replacement). Visit her Cannonball website and see for yourself. I'm sure you'll join me in saying "Ride, Dottie, Ride!"


Warm regards (and good luck Dottie!), 

Robert J. Zehr, M.D.

How to Prevent "Housemaid's Knee" 

     

Have you ever wakened to discover that the top of your knee is red, swollen and warm to the touch? If so, you are not alone. Most of those afflicted are people who are required to work on their knees, such as plumbers, roofers, carpet layers, and garden workers, or athletes who participate in a sport that commonly results in direct blows to the knee. This condition can also result from a motor vehicle accident, a fall, or other trauma to the knee and can be problematic for people who are obese, or who have rheumatoid arthritis and gout.

 

Often referred to in relation to the cause (i.e. "housemaid's knee") the condition is prepatellar bursitis.

 

The knee is surrounded by three major bursa sacs, which are closed sacs of fluid that serve to reduce friction between body tissues as they rub over one another. The prepatellar bursa is located at the tip of the knee over the kneecap. When it becomes inflamed, it commonly leads to rapid swelling on the front of the kneecap, skin that is tender and warm to the touch, and pain, most acutely with motion.

 

If you experience this condition, contact us immediately. The inflammation can rapidly become infected, making treatment more complicated. In rare cases, cellulitis, a bacterial infection of the skin and tissues below the skin, can develop which, if not properly treated, can occasionally spread to the bloodstream and cause a serious bacterial infection of the bloodstream and lymph nodes.

 

In fact, how your prepatellar bursitis is treated will depend on whether or not an infection is involved. If there is no infection, the condition can be treated with ice compresses, rest and anti-inflammatory and pain medications as needed. Often we will remove (or aspirate) the bursa fluid with a needle and syringe both to provide some relief and to obtain a sample to culture for the presence of bacteria. We may also require x-rays of the knee in order to rule out other structural causes of the inflammation. Occasionally, particularly extreme swelling can be treated with an injection of cortisone into the swollen bursa.

 

On the other hand, if the aspirated fluid is found to contain infection-causing bacteria, antibiotics will be administered, in many cases intravenously. As a precautionary measure, we may prescribe a regimen of antibiotics prior to receiving the lab results on the aspirated fluid. Several aspirations of the knee may be required in order to remove the infected fluid. Less commonly, surgical drainage and removal of the infected bursa sac may be necessary. 


While prepatellar bursitis is not uncommon, there are certain steps that can be taken to prevent its occurrence or recurrence. If you are going to be working on your knees for an extended period, or if you participate in contact sports that may result in trauma to the knees or legs, wear knee pads. Rest your knees on a regular basis and stretch your legs; alternatively, reduce the amount of time spent on your knees by switching activities after a time. Applying ice and elevating your legs after an extended period of time on your knees or following a leg intensive workout can also go a long way to reduce the risk of prepatellar bursitis.
