Knee Osteoarthritis, Prehabilitation
Conditions
Brief summary
Knee arthrosis has a high prevalence. Non-surgical treatment, such as exercise, is the first choice of treatment. However, most patients end up having a surgical procedure such as total knee arthroplasty. Following surgery with total knee replacement as much as 20% of patients report to not be satisfied with the results. It is noteworthy that this level of dissatisfaction has persisted over the last decades despite formidable progress in surgical methods and technology. Leg strength prior to surgery is associated with faster recovery post operatively, which may influence satisfaction. The investigators aim is to implement a period of strength training prior to surgery to evaluate if training prior to surgery may reduce the level of dissatisfaction post operatively.
