Anterior hip replacement

Direct anterior total hip replacement is a minimally invasive technique for total hip replacement surgery allowing for less pain and a quicker recovery.  Anterior total hip replacement is a great procedure to relieve the hip pain from hip arthritis and is one of the most successful surgeries in all of medicine. 

Robotic partial knee replacement Mako
Robotic MAKOplasty® Partial Knee Replacement

Also known as a unicompartmental arthroplasty, partial knee replacement can be a very successful procedure for the right patient with arthritis in only one part of the knee.  It can be done with robotic assistance (MAKOplasty®) to allow for more precise alignment of the components.

Robotic MAKOplasty® Total Knee Replacement

Total knee replacement is done much more commonly than partial knee replacement.  It involves replacing the entire knee with metal and plastic parts to relieve the knee pain associated with severe knee arthritis. It can now be performed with robotic-arm assistance (MAKOplasty®) for more precision and quicker recovery.

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!!"
