Total Knee Replacement

What is arthritis?
 

There are a few types of arthritis, the most common of which is osteoarthritis.  Osteoarthritis is a "wear and tear" disease of joints in which the cartilage wears out over time.  The cartilage is the cushion of the joints between the bones.  When the cartilage wears out the space between the bones decreases until the joint is "bone-on-bone".  This is the case for the x-ray examples above on the left hand side for a knee.

 

Arthritis can be treated with a few different modalities before surgery is indicated.  Anti-inflammatory medications (NSAIDs), physical therapy or a home exercise program, injections, weight loss, and activity modification should be tried first before surgery.  If these treatment modalities are not working to help a patient achieve the quality of life they desire then joint replacement is often the next step.    

What is involved with total knee replacement surgery?
 

Total knee replacement involves making an incision over the front of the joint and cutting the ends of the femur and tibia bones to get rid of the arthritic portions.  Cutting guides are then used to shape the bones to fit the implants.  The ligaments on the sides of the knee are then tested until the tension on both sides is about equal, this is called "balancing" the knee and helps to improve the longevity of the implants.  The last step involves cementing the components into place.  

 

The recovery process for total knee replacement is often a little more difficult than a total hip replacement.  More rehab is required postoperatively to make sure the knee doesn't become stiff.

Patient Testimonials

"I talked with over four orthopedic surgeons and their staff before selecting the surgeon for my knee replacement. I am pleased I chose Dr. Weidner. He is an excellent Surgeon. His PA, Ms. Richardson, spent over 30 minutes on the phone talking to me about things as the best use of pain medicine, excellent staff. Dr. Weidner uses the latest technology as robotics wisely. He is very willing to talk and work with me as the patient. I highly recommend Dr. Weidner."

"Dr. Weidner replaced my right hip and after one year replaced the left hip. I send my heartfelt gratitude, thank you for everything you have done for me. It is wonderful not to walk around in pain anymore. Not many people have a chance to say they have as great of doctor as I do."

"Dr. Weidner was referred to me by another doctor who was unable to address the issue with my knee after it became infected from an initial surgery (not done by Dr. Weidner). At the very first visit, Dr. Weidner was personable & took the time to answer my questions unlike most docs who rush you in/out. Every visit thereafter, Dr. Weidner's calm & positive approach left me feeling confident that I would finally have use of my knee. To date, I am farther along than I have ever been. Awesome doc"

"Dr. Weidner is great he has done 3 knee surgeries on me and I wouldn’t want any other doctor. He listen to what you have to say and works with you until he finds a solution."

"I highly recommend Dr. Weidner. Fell on the ice and required knee surgery. Excellent results and speedy recovery. He explained all aspects of surgery and how to best care for the knee. He is an excellent surgeon with a very caring attitude. Follows up to ensure everything is progressing as expected. Recently had an issue with rotor cuff and he once again demonstrated his professional competence through alternative options to prevent a worsening condition. Outstanding professional."

"Dr. Weidner is a great doctor. Takes the time to talk to you and really does care. Had a left hip replacement earlier this year and in spite of my age and physical condition, it was relatively pain free shortly thereafter. Hip works great. He's going to do my other hip in a couple of months. No worries here. I should add that the office is very nice and all of the assistants are very courteous and responsive."

"The best ever... the man is an artist!!! I've had 2 surgery procedures done, and both effective!!"
