Description of intervention(s) / exposure
PACT group: Participants will attend 3 additional one-to-one sessions at their local physiotherapy outpatient department pre-operatively of 60 mins, 30 mins and 30 mins duration respectively over a 3 month period, with appointments 6 weeks apart.
The fourth session of 20 mins duration will occur during their inpatient stay when the physiotherapist will attend to them in the ward setting. All physiotherapists conducting the intervention will have more than 3 years experience in musculoskeletal physiotherapy. They will also receive 16 hours training in the ACT method generally through an accredited ACT training provider. In addition, they will engage in 1 day of trial specific training in PACT, which will be provided by psychologists and physiotherapists experienced in developing and using the PACT method, and will be supported with a therapist training manual. All participants will be supplied with a patient manual, which supports the approach taken during the individual sessions. 'The initial session will include a thorough clinical assessment, and ongoing discussion between the therapist and participant to identify key values of the participant, linking these to behaviour goals around physical activity, action planning, identification of barriers and facilitators and prescription of one specific strength exercise. The strength exercise will target knee extensor and hip abductor strength, and the exact exercise and resistance will be personalised by the therapist based on an 8-10RM prescription.
Review sessions will explore progress made with regards to behavioural goals, exploring barriers/facilitators, goal review, and progression of exercises. All sessions will be conducted with a therapeutic stance aligned with Acceptance and Commitment Therapy principles as equal, respectful, empathetic and positive. Participants in this group will also receive the usual care treatment. All sessions will be recorded and assessed by the supervising clinical psychologist for intervention fidelity, including adherence and competence, using a standardised checklist developed a priori. Participating therapists will undergo monthly supervision sessions with the supervising psychologists in person or via videoconferencing.

Comparator / control treatment
All participants will receive usual care, which is attending a face-to-face one hour education class for patients and carers regarding the joint replacement pathway 3 months before surgery. It describes the surgical procedure, health professionals involved at all stages of the knee replacement surgery pathway, information regarding 1-2 relevant exercises used post-operatively, and expectations for recovery in the inpatient and outpatient stages. They will also receive a usual care patient handbook which provides the same information in a written format which is the resource used in standard care at Blacktown Mt Druitt Hospitals. This will be conducted by a physiotherapist with 2 or more years experience who is familiar with local joint replacement pathway procedures, in the local physiotherapy department.

Statistical methods / analysis
This is a mixed methods pilot randomized controlled trial.
Categorical baseline variables will be summarized with percentages. Continuous baseline variables will be summarized dependent on their distribution: normally distributed variables will be summarized using mean, standard deviation and 95% confidence interval, non-normally distributed variables will be summarized using median and interquartile range.
Safety of the PACT intervention will be assessed by three quantitative methods: psychological health outcomes before and after the PACT intervention before TKA surgery is performed, length of stay and complications after TKA surgery for the first 6 months.
Feasibility of the PACT intervention will be assessed by quantitative and qualitative methods. Quantitative methods will examine recruitment rates, time for sufficient participant recruitment, retention rates, attendance at appointments, and intervention fidelity. Qualitative methods will explore feasibility, enablers and barriers to the intervention from a therapist and participant perspective.
Acceptability of the PACT intervention will be assessed by both quantitative and qualitative methods. Qualitative methods will include analysis of treatment credibility scores, patient reported outcome measures and physical performance measures. Qualitative methods will explore acceptability of the intervention and training from a therapist and participant perspective.
We aim to recruit 51 people to our pilot study. This is adequate to test the safety, acceptability and effectiveness of the PACT intervention and of performing a randomised controlled trial at these sites, allow for any learning effects in the therapists administering the novel PACT intervention, and allow adequate randomisation with stratification. This will also provide sufficient data regarding estimate of effect size and variation for the treatment group which will inform a fully powered randomised controlled trial in the future. We are particularly interested in the effect of treatment on the outcomes of hospital length of stay and complications, but consideration of other outcomes will guide their use in a future, fully powered randomised controlled trial.

Summary
Brief summary
This study is the first to test a new physiotherapy approach to preparing for knee replacement surgery. This new approach is called PACT- Physiotherapy informed by Acceptance and Commitment Therapy. This is a method often used by psychologists to help people experiencing a range of issues that affect their mental health. This study is a pilot study, testing the new approach in 51 people and assessing results from a patient, therapist and hospital perspective before we use this approach in a larger study or in clinical practice.
