In recent papers he was focusing on the following fields of study:

Kai Nan An mainly focuses on Anatomy, Tendon, Surgery, Orthodontics and Biomedical engineering. His study connects Weight-bearing and Anatomy. His Tendon study incorporates themes from Ultimate tensile strength, Stromal cell, Carpal tunnel syndrome, Carpal tunnel and Bone marrow.

His research integrates issues of Saline and Hyaluronic acid in his study of Surgery. His research on Orthodontics also deals with topics like

  • Range of motion which connect with Muscle stiffness,
  • Thumb, which have a strong connection to Kinematics. His studies in Cadaver integrate themes in fields like Pulley and Elbow.

Between 2012 and 2021, his most popular works were:

  • Validation of shear wave elastography in skeletal muscle. (268 citations)
  • Ultrasound elastography: the new frontier in direct measurement of muscle stiffness. (151 citations)
  • The stabilizing mechanism of the Latarjet procedure: a cadaveric study. (140 citations)

In his most recent research, the most cited papers focused on:

  • Surgery
  • Internal medicine
  • Orthopedic surgery

Kai Nan An spends much of his time researching Tendon, Anatomy, Surgery, Cadaveric spasm and Biomedical engineering. His Tendon research includes themes of Ultimate tensile strength, Ligament, Carpal tunnel syndrome, Rotator cuff and Bone marrow. His Anatomy research integrates issues from Weight-bearing and Ultrasound.

The various areas that Kai Nan An examines in his Surgery study include Hyaluronic acid and Histology. His studies deal with areas such as Orthodontics, Bone plate, Torsion, Cadaver and Shoulders as well as Cadaveric spasm. In his research on the topic of Orthodontics, Muscle stiffness is strongly related with Range of motion.
