Telerehabilitation of Patients after Knee Surgery

About the project

Knee joint prosthesisMusculoskeletal pain, such as osteoarthritis of the knee, is the most common cause and the second largest contributor to “global disability”. In the past 20 years, the incidence of symptomatic arthritis of the knee has doubled among women and tripled among men and is expected to increase significantly in the future due to longer life expectancy and increased BMI. At the same time, the total number of operations with artificial knee (total knee replacement = TKR) is expected to increase by almost 700% by 2030.

Studies in many countries have unanimously concluded that up to 20% of knee patients have persistent pain following surgery. Hence, there has been an international focus on identifying the most optimal non-surgical type of treatment before any potential operation and to identify the most optimal rehabilitation following surgery. The purpose of this research project is to develop and test a tele-rehabilitation program that uses sensor technology for knee surgery patients following surgery.

The perspective is to be able to offer patients home exercise that can be performed more successfully on the patient’s own terms in their daily life, at lower cost, by a greater number of patients and with higher levels of compliance and intensity. The project will be reported to the North Jutland Regional Ethics Committee, the Danish Data Protection Agency and conducted according to the Declaration of Helsinki.

Participating in the clinical study are the Department of Orthopaedic Surgery and the Orthopaedic Research Unit of Aalborg University Hospital.

User-driven innovation

The telerehabilitation program will be developed in collaboration with patients, health professionals and researchers.

Target group

Patients who have undergone a knee operation and who reside in North Jutland.
