Alejandro Gonzalez Della Valle, MD

"I had partial knee replacement (arthritis) in January 2026. Dr Della Valle did a great job. Everything he told me to expect has come true including the timing for achieving certain rehab goals. He has a very calming and reassuring presence about him. Uber professional. I entered the surgery confident and have been extremely happy with the results. I would highly recommend Dr Della Valle to others."

"I recently had total hip replacement surgery performed by Dr. Della Valle at HSS, and cannot thank him, the care team, and the entire HSS staff enough for their exceptional care. From the very beginning--pre-surgery consultations including physical therapy, a thorough medical evaluation, and imaging--every step was handled with professionalism, compassion, and support. The pre-surgery and day of surgery teams were amazing in preparing me and making me feel comfortable with the process. This being my first ever surgery I was nervous to say the least. Dr. Della Valle and his team are truly outstanding. My recovery through the 5-week follow-up has been smooth and as expected. I all but 100% back to doing the activities I want to do. If you need hip replacement surgery, I cannot recommend Dr. Della Valle and HSS strongly enough. They are amazing!"

"This is the second time I have gone to Dr. Dallas Valle for a replacement. This time was a knee replacement. I am 8 weeks out and doing the same things that I was doing before surgery. I'm not in pain. Dr Della Valle is amazing and HSS is like a country club down to the gourmet food. His staff is also amazing. Shout out to Crystal This is the best place for replacements."
