Impact of Exercise Access on Physio Outcomes Post Knee Replacement (KEMTAI) 40 Exercise-Based

Not yet recruiting
Clinical Trial NCT07502040 (KEMTAI) is an interventional study for Knee Arthroplasty, Total and is currently not yet recruiting. Enrollment is planned to begin on March 31, 2026 and continue until the study accrues 40 participants. Led by Hull University Teaching Hospitals NHS Trust, this study is expected to complete by November 28, 2026. The latest data from ClinicalTrials.gov was last updated on March 30, 2026.
Brief Summary
To stay strong, patients should do some strength training at least twice a week. However arthritic pain can limit walking and activity. The wait for knee surgery can be long, which can lead to loss of muscle strength. Patients who need a new knee joint tend to be older. If older people do not exercise and become weak, they tire easily, and may take longer to recover after surgery. Patients recover faster after having...Show More

Participant Group/ArmIntervention/Treatment
ExperimentalKemtai Digital App
A randomised group of twenty patients will be granted access to the Kemtai digital App (the experimental arm) which provides an identical exercise prescription to the comparator (NHS standard of care intervention) but supports the patient through the exercise with tracking and real time (via AI) advice on corrective exercise techniques.

Active ComparatorNHS Standard of Care
A randomised group of twenty patients will be provided the NHS standard of care which is a paper based handout illustrating the exercises and the prescription to be done before and after surgery.

Primary Outcome Measures
Outcome MeasureMeasure DescriptionTime Frame
Length of stay in hospital
Number of hours between time of surgery and time of discharge
From time of surgery to the time of discharge from hospital, up to 52 weeks.
Number of post operative physiotherapy contacts
This measure is a count of the number of times that the participant has a documented contact with a physiotherapist after surgery. This may be in person or via telephone or video call, and may take place in hospital or after discharge from hospital after surgery.
From operation to 6 weeks post operation, up to 52 weeks.
Secondary Outcome Measures
Outcome MeasureMeasure DescriptionTime Frame
Oxford knee scale
The Oxford Knee Score (OKS) is a validated 12-question patient survey used to assess pain and functional limitations in patients with knee arthritis. Scores range from 0-48, with lower score indicating more pain and functional limitations.
From enrolment to six weeks post surgery
EQ5DL- a health-related quality of life tool.
The EQ5DL is a well validated quality of life measure. The scoring is 1-5 across each domain (mobility, self-care, usual activities, pain/discomfort and anxiety/depression) with a higher number indicating worse quality of life in each domain. Scoring: Results in a 5-digit code (e.g., 11111 for excellent quality of life and 5,5,5,5,5 for the worst quality of life
From enrolment to six weeks post surgery, up to 52 weeks.
Visual analogue scale
Includes a visual analogue scale (0-100) for patients to rate their health "today". A higher score is indicates better health.
From enrolment to six weeks post surgery

Eligibility Criteria

Eligible Ages
Adult, Older Adult
Minimum Age
18 Years
Eligible Sexes
All
  1. Adults aged ≥18 years.
  2. Referred to Hull University Teaching Hospitals NHS Trust t for Knee Arthroplasty at either Castle Hill Hospital or Goole District Hospital and has access to pre operative resources offered by the joint school physiotherapists.
  3. Has access to a device which is compatible with the operational requirements of the Kemtai programme.
  4. Able to give informed consent.

• Significant comorbid physical or mental illness considered by the investigator to either: prevent engagement in modified exercise; impair the participants ability to follow instructions place the participant at undue risk during exercise training adversely affect the recovery or rehabilitation trajectory

  • Patients already involved in an exercise or rehabilitation study will be excluded from this study.
  • Unwilling or unable to consent or complete study measures.
  • Has insufficient understanding of English or the languages that are supported by the Kemtai programme and does not have someone who can translate.
  • Is a prisoner
  • Has had a total hip replacement within the previous 6 months.
  • Is attending for revision of a previous knee replacement
  • Is having a knee replacement due to a tumour
  • Lacks visual acuity sufficient to follow stimuli on monitor or has someone who can give necessary verbal prompts
