My name is Manit, 53 years old from Chiengmai. The symptom started with there was a noise from the kneecap when I walked. It hurt when I walked up and down the stairs; I took the medicine on my own. Later, I took the medicine prescribed by the doctors I went to visit. The pain was not relieved. I learned from my friend who got the surgery from Dr. Somsak. It was a successful one, with good result so I decided to consult with him. Dr. somsak explained to me the cause of the pain. Moreover, the method to cure it. When I compared with those methods that I studied I then decided to take the treatment since it is the method that save time, take less timer to recover and less pain. The Doctor said that it is the MHTO procedure not the total kneecap replacement. After the surgery my knee is still my own knee not artificial knee Now the pain is almost all gone. For me I think MHTO surgery it is the best choice.
