Dr Khanuja is caring, professional and supportive. We had a conversation about my knees and with my X-rays taken during my visit in the late fall of 2024, and he showed why my knees were overloaded with arthritis and the distance between my bones in my left left were narrowing. He had reviewed those concerns at my last visit, but it was helpful to the XRsys again and learn more fully in this follow up visit. I am to return in 6 months as he is watching me closely in case of any changes in my knees.

Dr.K is outstanding! Ski instructors at Liberty Mountain try to always try to get him. He did my R knee 3 years ago. I'm 76 and have been teaching skiing for the past 27 years. We worked on the timing and I was able to rehab in time for the next season! Now we need to make a new plan for my L knee. He recommended PT and a follow up appt. In 3 months! Works for me!!!.
