Moon Jong Chang

For patients considering knee surgery, one detail matters: the clinic’s orthopaedic leadership is associated with a 16,000-case knee surgery experience, including work published on Total Knee Arthroplasty outcomes. Moon Jong Chang is a specialist at the clinic, where knee care is organized from diagnosis through surgery and rehabilitation. The clinic’s knee program emphasizes deciding carefully whether surgery is needed now or whether another treatment option fits better. It also connects operative care to recovery planning, including a 51-bed inpatient rehabilitation unit and a long-term “Well-Ageing” system addressing nutrition, immunity, and mental health. Chang’s career arc began in 1992 as a resident at Seoul National University Hospital, and his orthopaedic practice spans about 25 years. His training includes a Clinical Fellowship at the Joint Replacement Center in Louisville, a Sports Medicine fellowship at Johns Hopkins School of Medicine, and a Research Fellowship in Biomedical Engineering at Johns Hopkins University. Alongside clinical work, he held academic appointments including Assistant Professor at Hallym University College of Medicine and Professor of Orthopaedic Surgery at Seoul National University College of Medicine.
