The study has been designed to evaluate the clinical efficacy of PRP in acute ATR in terms of mechanical muscle-tendon function. 214 patients will be recruited to be randomly allocated to receive either PRP injection into the ATR gap or an imitation (placebo) injection. A cast, splint or boot is the current standard treatment.
The patient will receive the study/placebo treatment and will then participate in telephone follow-ups at weeks 4, 7 and 13 and attend for a 24 week follow-up in clinic, arranged by the recruiting site. The primary outcome is a Heel-rise Endurance Test at the 24 week follow-up appointment in clinic. An extended follow-up will be performed at 2 years after treatment, in which participants are requested to complete a questionnaire either by post or telephone.
Patients are identified in the outpatient trauma or orthopaedic clinic in a minimum of 15 hospitals across the UK. Recruitment began in July 2015 and will continue for 24 months or until the recruitment target of 214 participants is met. It is anticipated that each site will recruit a minimum of 1 patient per month.
PATH-2 is an academic clinical research study sponsored by Oxford University and is led by Professor Keith Willett, Professor of Orthopaedic Trauma Surgery. Project funding was awarded by the Efficacy and Mechanism Evaluation (EME) Programme and is funded by the Medical Research Council (MRC) and managed by the National Institute for Health Research (NIHR) on behalf of the MRC-NIHR partnership.
