"Dr Kronick always takes time to listen to me. We set out a plan concerning my right knee that I need to implement."
  • February 15, 2024
"He was right on time, listened to my questions, got clarification where needed, did the exam and gave me my instructions. Brief but thorough. I haven’t seen him in a few years, he’s a very good doctor"

"Dr Kronick has been my lifesaver! After being in a horrific accident in 2002, he has helped me through my body aging changes. He removed a lot of old hardware that put me back together and then he replaced both knees., the latest TKR Oct 2023"

"I was referred to Dr Kronick for soreness in a knee that I had replaced 3 years ago (that Dr now retired). I’ve had 1 visit with Dr Kronick and he was excellent. Thorough, patient and explained everything as he diagnosed the situation. I will be returning for follow up in a few months, as we wait to see if the problem clears up. I appreciate him discussing taking a conservative approach rather than recommending surgical correction near term. "

"If someone told you that their knee doctor was very experienced, knowledgeable, kind and patient, and that they have the utmost confidence that this doctor is the right choice for a successful fix, they would be talking about Dr. John Kronick. And they would be right."
  • January 4, 2024
"Dr. Kronick performed a two stage revision. I am so grateful that he found I had a staph infection, in my prior knee replacement, eradicated it and gave me a new knee which is beyond perfect now. He is the most caring and compassionate doctor I have ever had. Dr. Kronick tackles complex knee replacements that most other orthopedic surgeons aren’t willing to take on. He basically gave me a new lease on life. I highly recommend him, as I have had many knee surgeries, and he is the best."
  • November 28, 2023
"Doctor Kronick is very professional. I trust him completely and he did an awesome job with my knee replacement."
  • November 17, 2023
" Professionalism on a personal level. Major surgery of any kind can be physically and mentally stressful. Conversations with Doctor Kronick regarding operation procedures, recovery potential, and pain relief show confidence of successful orthopedic surgery experience. I believe in this confidence. Confirmed on many accounts of previous patients who's live's have been ever changed! " New Hip..New Life" Wether a hip, shoulder, knee, or other orthopedic surgery, there is NO SUBSTITUTE for experience! Make the right choice first so you won't have to do it again. Dr. John Kronick is the right choice for any of your orthopedic needs. Sincerely Confident, Greg Linn "

"Dr Kronick is a superior surgeon who performed a complete reconstruction of my right hip two years ago. His pre-surgery evaluation was complete, the surgery was completed on a very timely basis and his post-surgery follow up (including superior PT routines) was flawless. I just had my two-year check up and I am happy to report that everything is still working very well."
