Dr. Mollloy and staff are very kind and courteous. On 5/29/2020 I came in to have my right knee replaced. I had my left knee replaced on 3/18/2020. While under anesthesia on 5/29/2020 my left knee was manipulated without a doctor examining It see If It was necessary. As a result my left knee felt worse than It did before the manipulation and I have pain where I had no pain before the manipulation No explanation was given as to why this happened. Dr. Malloy encouraged me to keep up the exercises. He Is a great surgeon and kind man and despite this misstep I would recommend him .

Dr Molloy is awesome!! I've recommended him to several people already for their orthopedic surgeries!

Reviewed on Aug 17, 2021

I tried to see Dr. Molloy earlier than the 3 1/2 months after surgery that he had initially set up, but was told that despite my `Drop Foot' and related concerns he had no interest in seeing me before then. I felt that just a personal call to reassure me would have been very nice.

Reviewed on Aug 17, 2021

I sincerely wish that I could have given a better report, but the hospital experience was marred by the nurse's error and the fact the Dr. Molloy had no time to speak to me personally following my frightening experience of 'foot drop,' left me feeling anxious and afraid. A phone call from him would have made all the difference .
