Description of intervention(s) / exposure
All participants received standard post-operative ward physiotherapy as clinically determined by the treating physiotherapist for the first three days post-operatively. Throughout the intervention stage of the trial, from Day 4 to discharge, all participants continued to receive one ward physiotherapy treatment each day, following the standard orthopaedic clinical pathway used at the hospital. The experimental treatment was in addition to usual care. From Day 4 after surgery, participants completed one of the two aquatic treatment programs each day until discharge. All treatments were one-on-one individual physiotherapy treatment sessions to standardise intervention between the groups and also to allow close monitoring of the physiological response to immersion in the early days after surgery. The aquatic physiotherapy intervention consisted of exercises in 30% weight-bearing (chest deep water) focusing on strength using speed of movement as well as functional activities such as step ups and squats, walking forwards, backwards and sideways, balance exercises and open-chain strengthening exercises using equipment for increased resistance eg flippers. The water exercise program was undertaken in 10% weight-bearing (neck-deep water) at a slow speed and involved exercises such as marching and single-leg standing on the non-operated leg, walking forwards and general upper limb strengthening exercises. The number of additional physiotherapy treatments was recorded for all participants and on average, participants received 3.5 additional treatments while in hospital. Each treatment session lasted 40 minutes and the average length of stay was 7.5 days. The primary end-point of the trial was Day 14. After discharge home from the acute hospital and having completed the Day 14 assessments, participants were free to undertake whatever, if any, post-operative physiotherapy they chose.

Comparator / control treatment
All participants received standard post-operative ward physiotherapy as clinically determined by the treating physiotherapist for the first three days post-operatively. Throughout the intervention stage of the trial, from Day 4 to discharge, all participants continued to receive one ward physiotherapy treatment each day, following the standard orthopaedic clinical pathway used at the hospital. The control group received a second ward physiotherapy treatment each day from Day 4 until discharge. All treatments in the ward were one-on-one individual physiotherapy treatment sessions to standardise intervention between the groups.The additional ward treatment was a second session of the same exercises and included strength and range of motion exercises in supine and standing as well as mobility/gait re-education. The number of additional physiotherapy treatments was recorded for all participants and on average, participants received 3.5 additional treatments while in hospital. Each treatment session lasted 40 minutes and the average length of stay was 7 days. The primary end-point of the trial was Day 14. After discharge home from the acute hospital and having completed the Day 14 assessments, participants were free to undertake whatever, if any, post-operative physiotherapy they chose.

Summary
Brief summary
No studies to our knowledge have been published on the use of aquatic physiotherapy from Day 4 post-operatively after THR or TKR surgery. This randomised controlled trial was therefore undertaken to investigate whether inpatient aquatic physiotherapy from Day 4 in addition to usual ward physiotherapy improved early functional recovery more than non-specific water exercise or additional ward physiotherapy. The primary endpoint of the trial was Day 14. Considering the usual level of activity in healthy older people, rehabilitation to optimal function after joint replacement is usually the aim of physiotherapy. Reduced strength and gait dysfunction can persist for many months after joint replacement. If return to normal function and activity is the goal of physiotherapy intervention after joint replacement surgery, follow-up beyond the early post-acute phase is important to understand the longer term impact of early rehabilitation. Participants were therefore followed up for six months after surgery to more thoroughly gauge functional recovery.
