Dr. Zachary Weidner, M.D.

Dr. Weidner is a board certified fellowship trained orthopedic surgeon with a subspeciality focus in hip and knee joint replacements.  He has a particular interest in minimally invasive and muscle sparing joint replacement surgery.  One of his focuses is using the direct anterior approach for hip replacement using the specialized orthopedic Hana ® operating table.  This procedure allows for a quicker recovery with less pain and lower risk of dislocation compared to more traditional methods of hip replacement.  It also allows for x-ray confirmation of the implants during the surgery to ensure accurate recreation of the normal hip biomechanics and an opportunity to check the patient's leg lengths before leaving the operating room.  He also specializes in robotic-assisted partial and total knee replacements (MAKOplasty®) which can allow for more precise component implantation and early return to function. Mako total knee replacement surgery is a new technology available that has a chance to change the game regarding knee replacement surgery to improve outcomes and lessen pain. 


Dr. Weidner is a native of Pittsburgh, PA and received his B.A. in mathematical economics from Brown University where he graduated Magna Cum Laude.  He went on to earn his medical degree from the University of Pennsylvania School of Medicine in Philadelphia before completing his orthopedic surgery residency at Mount Sinai St. Luke's Roosevelt Hospital Center in New York City.  Upon completion of his residency he pursued one extra year of subspeciality training in hip and knee replacement surgery at the Anderson Orthopaedic Clinic.  He is proud to have scored in the 94th percentile on Part I of the American Board of Orthopaedic Surgeons examination.  He loves to spend time outside with his two young children and wife when not at work.

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!!"
