Study summary

The goal of this clinical trial is to determine if rehabilitation delivered by telehealth works as well as rehabilitation delivered in person at a clinic, for people recovering from total knee replacement surgery. The main question it aims to answer is:

  • Does rehabilitation by video call lead to knee-related quality of life that is just as good as rehabilitation completed in person at a clinic?

Researchers will compare a telehealth group to a clinic group to see if telehealth rehabilitation works as well as in-person rehabilitation.

Participants will:

  • Take part in 9 rehabilitation sessions over 6 weeks, either by video call from home or in person at a clinic
  • Follow a home exercise program using an online app
  • Answer questions about their knee and daily activities before surgery, and again at 7 weeks, 6 months, and 12 months after surgery
  • Have their knee movement and physical abilities, such as walking speed and climbing stairs, measured by a therapist before surgery, and again at 7 weeks, and 12 months after surgery
Read the detailed description

This randomised controlled, single-blinded, non-inferiority trial compared telehealth-delivered versus clinic-based (in-person) early-stage rehabilitation following primary total knee arthroplasty (TKA).

Following written informed consent and pre-operative baseline assessment, participants were randomised to either a Telerehabilitation or Clinic group using a computer-generated sequence, with allocation concealed by an independent researcher. The primary outcome assessor remained blinded to group allocation throughout the study.

Both groups received an identical rehabilitation protocol comprising nine supervised sessions delivered over a 6-week post-operative period (twice weekly for the first three weeks, followed by once weekly for a further three weeks), commencing 4-7 days after surgery. Each session lasted approximately 30 minutes and was delivered by Accredited Exercise Physiologists. Sessions addressed pain and swelling management, safe and progressive ambulation, activities of daily living, review and progression of a structured Home Exercise Program (HEP), and monitoring of knee range of motion.

The Clinic group attended sessions in person at a single private rehabilitation clinic. The Telerehabilitation group received the same sessions remotely via a telehealth platform (Coviu, Sydney, Australia). Both groups were provided the HEP through an online exercise-delivery platform (Physitrack, Physitrack Ltd., London, UK), which included video-based exercise demonstrations, adherence monitoring, and secure patient-provider messaging. HEP frequency and intensity were progressively modified over the 6-week program according to individual pain tolerance, knee range of motion progression, and treating therapist judgement.

Outcome assessments were conducted pre-operatively and at 7 weeks (following completion of the rehabilitation intervention), and at 6 and 12 months post-surgery. All in-person clinical assessments were conducted by a single therapist who remained blinded to group allocation.

The study hypothesis was that telerehabilitation would be non-inferior to clinic-based rehabilitation with respect to the primary outcome measure, with no clinically meaningful differences expected between groups in secondary patient-reported outcomes, active knee range of motion, or objective measures of lower-limb function.

Sample size was calculated to detect non-inferiority at the 7-week timepoint, using a non-inferiority margin of 10 points (based on the published minimal clinically important difference for the primary outcome measure), an assumed standard deviation of 12.5 points, an alpha level of 0.05, and 90% power. This yielded a requirement of 42 participants per group, increased to 54 per group (108 total) to allow for an anticipated 25% loss to follow-up. Both intention-to-treat and as-treated analyses were performed in accordance with CONSORT guidelines for non-inferiority trials.

Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
