I had a full knee replacement on my left knee in 2015 with Dr. Hajnik, and a full knee replacement on my right knee in 2016. I cannot express enough how happy I am with the outcome, and how incredible Dr. Hajnik was throughout the process of both replacements. HIs consultation for the months leading up to the replacement was thorough and professional, and his diagnosis and counsel was incredibly valuable and reassuring. The attention to detail w/prep, surgery, and post surgery was AAA+.
