About Maximilian Peter Forssten

Dr. Forssten graduated medical school at Karolinska Institute in Stockholm, Sweden (2020). After working as a junior doctor in the Department of Orthopedic Surgery, he undertook a joint research and medical internship at Orebro University Hospital (2020). Upon completion, Dr. Forssten accepted a position as a resident in the Department of Orthopedic Surgery at Orebro University Hospital (2022).

Dr. Forssten is currently enrolled as a PhD-student in surgical sciences at Orebro University where he is researching preoperative risk assessment and the role of frailty in the management of hip fracture patients under Associate Professor Shahin Mohseni.
