Director Gao didn't know how to explain, any further explanation would only muddle things more.
Fortunately, Xu Zhiliang helped him out unwittingly, noting that the patient for this knee joint replacement surgery had rheumatoid arthritis.
Xu Zhiliang asked Zhang Lin and the second and third assistants at the operating table to observe the pannus, a layer of new blood vessels that forms on the synovial surface of the knee joint, causing the cartilage to be completely invaded. Pathological granulation tissue and fibrous tissue form adhesions, causing the knee joint to become fibrous ankylosis due to adhesions.
The wall of the operating room had an electronic screen, which the graduate students and standard training students viewing from the bottom huddled around to see.
The assistants on the table also adjusted their positions to get a good view and observe the internal changes of a typical rheumatoid arthritis patient's knee joint.
