Targeted Rehabilitation to Improve Outcome After Knee Replacement- A Physiotherapy Study

The TRIO-physio study is looking at how well patients with osteoarthritis recover after knee replacement surgery (also known as Total Knee Arthroplasty (TKA)). Currently around 20% of patients are not satisfied after TKA. This project will look to find out if the research team can identify patients who will not recover well at an earlier stage, so that these patients can be helped sooner.

The study will try to determine if doing intense physiotherapy with patients who are not doing well at the first review (6 weeks after their operation) can improve how well they have recovered at one year.

About this study

The study is a randomised controlled trial comparing the effect of intensive physiotherapy compared to current standard of care therapy, targeted to patients performing poorly at 6 weeks following total knee replacement.

All patients will be made aware of the study pre-operatively at the recruiting centres. Prior to surgery they will complete the routine pre-operative outcome assessment questionnaires (Oxford Knee Score and EQ-5D) as part of the national PROMS program and then undergo the local standard total knee replacement and immediate post-operative care pathway.

All patients will be routinely reviewed 6 weeks post-operatively by the usual clinical teams. At this review the Oxford Knee Score will again be assessed. Those patients who report a score of 26 or less (on the 0-48 OKS scoring system), which is defined as poor by the Kalairajah classification (Kalairajah, 2005), will be approached to consent. If consent is given and the patient is eligible to enter the trial, randomisation into one of the following groups will occur: to standard care (encompassing a one off physiotherapy review, 6 weeks of home exercise prescription and final review) or to an interventional arm, where 18 sessions of structured physiotherapy will be administered over a 6 week period, where 6 of these sessions will be 'contact sessions' performed under the supervision of the physiotherapist.

All trial participants will be reviewed immediately post intervention (i.e. at 14 weeks post operation) and then by postal questionnaire at 26 and 52 weeks post-operation.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Undergoing primary total knee arthroplasty for osteoarthritis.
  • Defined poor outcome (Oxford Knee Score less than or equal to 26) at first post-op review (6 weeks).
  • Patients are able to consent and willing to comply with the study protocol

Exclusion criteria

  • Patients undergoing revision knee arthroplasty or fully constrained knee arthroplasty
  • Knee replacement for a diagnosis other than osteoarthritis
  • Patients unable to attend the study physiotherapy intervention centre
  • Procedures done purely for pain relief (such as for patients with no walking capacity)
  • Patients already receiving ongoing structured post-operative exercise rehabilitation

Treatment and study plan

Intensive physiotherapy

Procedure

Participants will visit hospital for physiotherapy sessions once a week for 6 weeks in addition to completing prescribed exercises twice a week at home on their own.

Home physiotherapy exercises

Other

Patients will be asked to complete prescribed exercises at home on their own 3 times a week for 6 weeks.

Primary outcomes

  1. Oxford Knee Score

    Time frame: 52 weeks post-operation

    Primary analysis will be 52 week outcome (Oxford Knee Score) in the enhanced physiotherapy intervention group compared to the current standard of care physiotherapy treatment group.

Secondary outcomes

  1. Patient satisfaction

    Time frame: 52 weeks post-operation

    Assess patient satisfaction with knee arthroplasty. Assessed with a specific patient satisfaction question:

    Are you satisfied with your knee replacement? (Possible responses: very satisfied, satisfied, dissatisfied, very dissatisfied) Specific satisfaction with pain relief and functional ability will also be assessed. 4 additional sub-questions relating to facets of satisfaction:

    • "How well did the surgery relieve the pain in your affected joint?"
    • "How well did the surgery increase your ability to perform regular activities?"
    • "How well did the surgery allow you to perform heavy work or sport activities?"
    • "How well did the surgery meet your expectations?"

    (Possible answers: excellently, very well, well, fairly, poorly)

  2. Knee function

    Time frame: week 8 and week 14

    Assess the actual physical function of the patient as a result of the differing physiotherapy interventions. Timed-get-up-and-go-test, assessed prior to (8-weeks post op) and following 6 week physiotherapy protocol (14 weeks post-op).

  3. Cost effectiveness

    Time frame: 52 weeks post

    To evaluate the cost effectiveness of enhanced targeted physiotherapy.
