About

Knee osteoarthritis (OA) is a common, chronic, and costly condition, and patients with advanced knee OA and severe disability often require a total knee replacement (TKR) surgery. In Singapore, after TKR surgery, nearly all patients who are home discharged are referred to hospital-based outpatient rehabilitation. Although outpatient rehabilitation attendance is associated with better functional outcomes, access to rehabilitation care is limited as outpatient rehabilitation is costly and inconvenient for patients and their caregivers, resulting in suboptimal adherence. A tele-monitored home-based exercise program provides the best access to rehabilitation care and is a potential alternative for the majority of patients who do not require intensive "hands-on" rehabilitation therapy.

The primary aim of this non-inferiority randomized controlled trial is to compare patient functional outcomes and cost-effectiveness of an innovative tele-monitored rehabilitation program versus that of currently standard, hospital-based outpatient rehabilitation program among patients post TKR.

Full description

Study Hypotheses

Primary hypothesis: A 10-week home-based exercise program, combined with tele-monitoring of functional outcomes, will not be inferior to an 10-week hospital-based rehabilitation at 3 and at 6 months after total knee replacement (TKR) in improving physical function (fast gait speed).

Secondary hypothesis 1: A 10-week home-based exercise program, combined with tele-monitoring of functional outcomes, will not be inferior to a 10-week hospital-based rehabilitation at 3 and at 6 months after TKR in improving knee pain, physical impairments, and health-related quality of life.

Secondary hypothesis 2: A 10-week tele-monitored home-based exercise program will be more cost-effective than the 10-week hospital-based rehabilitation in total TKR-related costs

Approach and Methods

This will be an assessor-blinded, parallel design, non-inferiority randomised controlled trial, with assessments preoperatively(baseline), 3 months, and 6 months after total knee replacement surgery. The protocol conforms to the CONSORT guidelines for non-inferiority randomized controlled trials. Post TKR, all participants will undergo daily inpatient rehabilitation. At discharge, they will be given a standard booklet with advice on ice therapy and home exercises to be performed. Two weeks post TKR, randomization will occur and participants will be randomised to receive either the telemonitored home exercise program or the hospital-based rehabilitation program.
