Dr. Sloan serves as the Director of Robotics in Orthopedic Surgery at Emerson Health, where he leads the advancement of robotic-assisted joint replacement techniques.

He practices at Orthopedic Affiliates in Concord, Massachusetts, where he was the first fellowship-trained joint replacement surgeon to bring advanced surgical techniques from Boston to the Emerson Hospital community.

In addition to primary joint replacement, Dr. Sloan has introduced specialized expertise in:

• Treatment of joint replacement infections
• Revision (redo) hip and knee replacement surgery
• Periprosthetic fractures (fractures around joint implants)

This has allowed patients in the region to access complex, high-level orthopedic care locally—without needing to travel into Boston.

Excellent Doctor & Surgeon! VERY EXCELLENT DOCTOR AND SURGEON!!! I honestly have nothing negative to say about Dr. Sloan. My husband’s hip replacement went extremely well, and he is recovering very nicely right now! We are very grateful for the excellent care he received. ❤️ I normally don’t write reviews, but this time I feel like I have to address something because it has happened more than once. Even before my husband’s hip replacement surgery, we waited forever for a call back from his Medical Assistant regarding information we were supposed to receive or things Dr. Sloan requested. Unfortunately, we never received a call back, and at the time, we let it go. After the surgery and his follow-up appointment, my husband was supposed to receive another call from the Medical Assistant with information Dr. Sloan wanted him to have. We called several times over the course of weeks and left multiple messages, but again, we never received a call back. My husband eventually had to drive directly to the office just to get the information he needed. So, please, do your job, dear Medical Assistant. Communication and follow-up are very important, especially when it involves a patient recovering from surgery. I am also a Medical Assistant, so I understand how this works and how important it is to follow up with patients. Again, Dr. Sloan is an excellent doctor and surgeon, and we are extremely happy with my husband’s surgery and recovery. This review is specifically about the lack of communication and follow-up from the Medical Assistant.

A-fib interaction with hip replacement I had a great experience with Dr. Sloane and his team, and my new hip is great: no pain, more range of motion. The only negative aspect of the entire experience was that 4 days after my surgery, my previously diagnosed mild A-fib suddenly became much more active, acting up every evening as opposed to the less than once per week prior to surgery. I consulted with my cardiologist, wore a heart monitor for two weeks, and the A-fib calmed down eventually. My physical therapist told me that there is a strong association of A-fib activity following hip replacement surgery. The PT said people with A-fib should be told about that risk when deciding whether to do hip replacement, and then again when they are scheduled for hip replacement, so they won't be taken by surprise as I was. That makes sense to me.

Dr Sloan is an excellent surgeon. All of my questions both before and after the surgery were answered. The surgical procedure was fully explained and I was given a clear picture of what to expect after the hip replacement was done. All of this information was very helpful in speeding up my recovery.

Outstanding Orthopedic Surgeon Dr. Sloan performed a TKR (right knee) on March 11, 2026 at Emerson Hospital. This was my second TKR/TKA (left previously done in 2014), but my first with Dr. Sloan.Similar to many reviewers, I did my research and chose Dr. Sloan, and couldn't be more pleased with my choice.The difference between my two TKRs is remarkable; the 2014 procedure (not at Emerson) was an ordeal. Dr. Sloan's entire process, from pre-op testing, to discharge on the same day as my procedure, was a pleasant experience.I'm not a young man. I will turn 80 soon. Yet, I had 100 degrees of motion one day after surgery, was walking without a cane by day 4, and never had a need to take an opioid for pain.Thank you, Dr. Sloan!

Excellent experience having a total knee replacement by Dr. Sloan. Every question was answered and all details were taken care of by him and his staff. I had repeatedly heard wonderful recommendations from other patients as well as medical personnel, while having the various tests & scans done. My day surgery went as planned and my recovery has been amazing!

Great experience all around I had my left knee replaced after many years of pain from self-inflicted sports injuries. The entire staff from pre-surgery, surgery post-op and the medical office could not have been better. I was very nervous about this and they listened and made me feel at-ease. I'm happy to say I'm 2 months in recovery, walking pain-free again and looking forward to getting back my former active lifestyle - perhaps without the basketball and football this time around.

Fantastic Experience Dr. Sloan did my recent left hip replacement surgery. He was thorough in his explanations, kind in his approach and most importantly highly skilled in the actual procedure. This was an anterior replacement and the healing process was much better with less pain than my other hip replacement done posterior (by a different surgeon).

I went to my 1 year follow up appt. for my anterior hip replacement at the Highlands Common satellite clinic. I checked in and within 2/3 minutes was getting xrays and brought to the room to wait for Dr. Sloan. Immediately, Denise came in for the preliminary questions and exam. When she was done, Dr. Sloan came in, without delay, to show and discuss the xray and give the good news that all was well. I was out and in my car within 20-25 minutes. Overall, Dr. Sloan and his team are top notch and I can not recommend this practice any higher than I have since the start of this experience. A+ rating

I had a total knee replacement performed by Dr. Sloan three months ago, and I couldn’t be happier with the results. I’m now pain-free and have regained full range of motion, which has truly transformed my quality of life. Dr. Sloan took the time to answer all my questions and address my concerns with patience and clarity. I highly recommend Dr. Sloan for anyone considering knee replacement surgery!
