In the afternoon of January 22nd, Xiangtan Central Hospital started its fifth video meeting with MATAT. On the meeting, MATAT invited Dr. Dabby Dan, a renowned Orthopedic Surgeon and the Head of the Israeli Hip and Knee Society, to introduce the alignment in clinic practices. Tang Xinqiao, the vice president of the hospital, who is also an orthopedics specialist, key members of orthopedics department, and medical students attended the meeting.

For orthopedic surgery such as joint replacement, the effect of "alignment" (that is, the positional relationship between the broken ends of the bones) is a more important part of the whole treatment process. In the video lecture, Dr. Dan elaborated the comparison between mechanical alignment and kinematic alignment and showed some real cases. In the discussion part, Dr. Dan answered several questions on "patella replacement" and "distal femoral osteotomy" in response to audience.

Tang Xinqiao said, “some medical concepts such as‘respect the nature of patients’ put forward by Dr. Dan in the lecture are very innovative and enlightening to us. This lecture has further broadened our horizons. "
