This review is on Dr. P. Kang who did my total knee replacement 6/3/2014. I had an appt. in Nov. 2014, after Dr. Kang performed complete knee replacement. I Complained of swelling and pain, was told that was normal. Made Appt. for the end of Feb. 2015. In January 2015, I called and left 3 messages on assistant's phone asking to see him , pain, swelling, and knee making crackling sound when opening and closing. My calls went unreturned. Went to Dr. Crovetti had arthroscopic surgery to clean up scar tissue and am now I am in process of having the surgery redone. This has been a terrible year and a half. Al Ghilarducci 11-16-15
