The trial is looking for adults booked for a first, planned total knee replacement who show signs of depression on a questionnaire. It tests a group talking-therapy workshop called Acceptance and Commitment Therapy before surgery.

Age
18 Years to 100 Years
Sex
All sexes can join.
Disease stage
People scheduled for routine primary elective total knee replacement (TKA), a first planned knee replacement.
Earlier treatment
People currently having any other "talking therapy" cannot join.
Biomarker or test result
A score of 10 or more on the Depression part of the DASS-21 questionnaire before surgery.

Main reasons for not taking part

  • Planned revision surgery, partial (uni-compartmental) knee replacement, or replacement of both knees.
  • No mobile phone for text messages, or no way to answer online questionnaires.
  • Surgery date moved by 3 months or more, earlier or later.
  • Further bone or joint surgery planned in the next 3 months.
  • Not attending the pre-operative education class, or unable to follow the trial schedule.

About the trial

What the trial wants to find out

Regarding psychosocial factors and outcomes in total knee arthroplasty (TKA), most of the current literature and the investigators' previous work suggest that depression, anxiety and pre-operative pain strongly predict worse outcomes following TKA. Despite some conflicting evidence, on the whole, the current literature suggests that psychological intervention in TKA patients could help to improve outcomes. In recent years, Acceptance and Commitment Therapy (ACT) has been receiving more attention as it may be more effective than the more traditional cognitive behavioural therapy in treating older people with chronic pain. ACT includes a combination of acceptance and mindfulness methods along with activation and behaviour change methods.

Read full original descriptionShow less

There have been several studies examining ACT in patients undergoing orthopaedic surgery. These studies have found that attending a pre-operative ACT workshop and receiving text messages reinforcing ACT can reduce use of pain medication, reduce post-operative pain and improve function following surgery. There are also two study protocols published which plan to investigate ACT in TKA patients but the findings of these studies are yet to be reported.

In this feasibility study, the investigators propose to investigate the acceptability and feasibility of a pre-operative ACT workshop in TKA patients considered to be at risk of poorer outcome based on a depression score. If found to be acceptable and feasible to both patients and those who will deliver the ACT sessions, a larger study will be performed.

The 2 groups in the trial

  • Acceptance and Commitment Therapy (ACT)Treatment being tested

    Patients will attend a half-day virtual pre-operative ACT group workshop delivered by physiotherapists. Intervention group patients will also receive booster post-operative ACT text messages once a week for 6 weeks and a telephone follow-up with a physiotherapist at 6-8 weeks. The workshop, text messages and follow-up with a physiotherapist will be in addition to standard care.

    Treatment: Acceptance and Commitment Therapy

  • ControlNo study treatment, for comparison

    Patients in the control group will receive standard care; All patients should attend a 1-hour face-to-face group pre-operative education class. Patients in either group will have access to a helpline where they can speak to a nurse to discuss any problems or concerns. All patients will also receive a follow-up phone call from a nurse within 5 days of discharge to check their progress and will attend a 6-12 week follow-up clinic with their surgeon.
