Welcome to PROP-OA


Due to COVID-19 (Coronavirus), recruitment of patients to the PROP OA trial has been paused until further notice and Keele Clinical Trials Unit is operating remotely.

  • If you had an appointment scheduled at a PROP OA clinic, this has now been cancelled. We will get back in touch once we are able to continue with the trial.
  • If you have already attended an appointment in which you were allocated a treatment, you will continue to remain in the trial. Please continue to follow the advice given to you by your physiotherapist during your last PROP OA appointment. You may not receive follow-up questionnaires in the post. Instead, Keele CTU may call you to ask you these questions over the telephone.
  • If you agreed to consent to further contact, a member of the trial team may call you about the possibility of taking part in an interview, which would be completed over the telephone.

If you have any urgent queries regarding the trial, or the treatment that you have received as part of the trial, please call the Keele CTU emergency number on 07733 110413 and quote PROP OA.

If you have any non-urgent queries regarding the trial, please call the PROP OA study team at Keele CTU on Freephone 0800 130 3419 and leave a voicemail message. These messages are checked regularly and your call will be returned as soon as possible.

We apologise for any inconvenience caused during this challenging time and thank you for your understanding.
