Platelet-Rich Plasma Injections (PRP)

In recent years doctors have learned that the body has the ability to heal itself. Platelet-rich plasma (PRP) injections have the potential to use the body's natural growth factors to create a healing environment for certain orthopedic conditions. PRP injections are different from cortisone & steroid injections which do not have any healing potential and instead work as anti-inflammatories to mask the pain.


PRP injections are a new treatment option still being studied. They have been shown to be most effective for chronic tendinitis conditions such as rotator cuff tendinitis, achilles tendinits, tennis elbow, and patellar tendinitis. There is also some evidence they can help for patients suffering from knee arthritis as well.  


Once your doctor believes you are a good candidate to benefit from a PRP injection you will need a second appointment to perform the procedure. At the procedure appointment your blood will be drawn in the office and placed in a centrifuge to separate the platelet rich portion of your blood which has the greatest amount of healing growth factors. This portion of your blood is then injected back into your body at the site which is causing you pain to try to activate a healing response. The injection can cause some discomfort for a few days but should not require any time missed from work and patients can usually continue with most of their normal activities. 




PRP injections are unfortunately usually not covered by insurance (though patients may want to call their insurance companies to ask prior to the procedure). Our office is offering these injections at a cost to the patient of $650 per injection.

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!!"
