Everyone at the clinic was very kind. Dr Molloy is certainly my "hero" in replacing my right knee. I have scheduled to have my left knee replaced on December 11th. I am so anxious to have this done. The right knee feels so good. My experience with Dr. Molly and his entire staff is excellent

Reviewed on Sep 24, 2019

My left knee was very sore and I wanted to get a "shot" in that knee to provide some comfort until my December 11th surgery. The Physician assistant Dr. Bill talked to Dr. Molloy and they both agreed to give me a shot in the left knee. That certain did the trick. Today I am without pain in that knee. So anxious to have the left knee replaced.

My visit with Dr Molloy was one of the best experiences I have had with the Cleveland Clinic. He took his time with me, answered all my questions, discussed options for further treatment down the road, what to do and how to handle situations if they arise. I was totally comfortable and pleased with my visit! Was difficult to get an appointment but after meeting him I now know why everyone wants to see him! He's worth the wait!!!
