Brief summary
Health professions need to prepare for the large increase in the number of older people with OA requiring health services including TJA surgery. Older age and poor physical function influences the postoperative prognosis of TJA. At discharge from hospital after TJA, studies have shown that gait speed can be severely impaired among older patients. The investigators hypothesize that an exercise program of 6-12 weeks will be beneficial for patients that are undergoing TJA.
Detailed description
More than 300.000 Norwegians above 20 years of age have osteoarthritis (OA) . There has been a significant increase in the prevalence of OA over the decades. In the United States knee OA affects 19% of adults aged 45 years or older. OA is associated with an extensive high economic and personal burden, largely attributable to the effects of disability, comorbid disease, and the expense of treatment. Given the aging population, the number of total joint arthroplasty procedures (TJA) for hip and knee is likely to increase substantially. In light of poor physical function prior to surgery among older patients and the likelihood of an added decrease during hospitalization and risk of poorer outcome after surgery, it is hypothesised that prehabilitation (preoperative exercise) would improve outcomes after surgery, however evidence for its efficacy is still lacking

| Change in aerobic capacity | 1 week before intervention, directly after intervention as well as 6 and 12 weeks after TJA-surgery | 6 min walk test |
| Change in transitional ambulation | Change measure: Baseline, within one week after intervention, 6 weeks after intervention, 3 months after intervention, 6 months after intervention and 12 months after intervention | Timed-up and go Test (TUG) |
| Change in pain measured with numeric rating scale (NRS) | Change measure: Baseline, within one week after intervention, 6 weeks after intervention and 3 months after intervention | NRS - Single score, low score indicates low pain, high score indicated high levels of pain |
| Length of stay in hospital | From date of hospital admission until the date of hospital discharge, assessed up to 12 months | Number of days |
| Change in the ability to climb stairs | Change measure: Baseline, within one week after intervention, 6 weeks after intervention, 3 months after intervention, 6 months after intervention and 12 months after intervention | Stair-climb test. Timed performance from start to stop |
| Change in Health Status measured with EuroQol-5 dimensions (EQ-5D) | Change measure: Baseline, within one week after intervention, 6 weeks after intervention, 3 months after intervention, 6 months after intervention and 12 months after intervention | EQ-5D, five dimensions of health scored from 1-5, with 1 being no problem and 2-5 indicate increasing problem (higher score = increase in problem) |
