Description of intervention(s) / exposure
This study will aim to answer the question of whether single LR-PRP injection for gluteal tendinopathy results in long term radiological improvement in imaging abnormalities to the tendons.
This will be a single-centre trial conducted as a follow up of a double-blind randomised control trial.
The subjects will be drawn from the double-blind randomised control trial along with those who were in the open labelled extension to the trial, who had a pre-study MRI.
Participants will be asked to give consent for researchers to access pre and post-treatment MRI scans. For those who have not had a post-treatment MRI, they will be asked to have an MRI scan performed. There will be no requirement for participants to attend for visits (other than to have an MRI if needed).
A radiologist will assess pre and post treatments MRI scans using a grading system. The radiologist will be blinded to the identity of the patient and to which post-trial MRI relates to which pre-trial MRI. Once the imaging has been scored statistical analysis will be used to determine whether the changes are significant. This is anticipated to be completed over a 9 month period.

Diagnosis / Prognosis
Comparator / control treatment
Pre treatment MRIs will be compared to post treatments MRIs in two groups - one who has had leucocyte-rich PRP ( LR-PRP) and the control group who has had a corticosteroid injection
Control group
Active

Outcomes
Primary outcome [1] 307011 0
The primary outcome measure will be the MHIP Score. This grading system has 5 components which contribute to the composite score. The degree of trochanteric bursitis is scored from 0-4, the tendon pathology from 0-5, muscle atrophic changes from 0-4, Cortical irregularity from 0-3 and Bone marrow oedema from 0-1 with a total score ranging from 0-17. Scores will be measured at baseline and 2 years
Timepoint [1] 307011 0
2 years post treatment
Secondary outcome [1] 353815 0
Secondary outcome: stratifying variables (responder vs non responder) correlation between Melbourne MHIP MRI tendon Grading system scores at baseline and 2 years Responders will be determined by the Relative Effect per Patient of > 0.2 (based on Huber and OMERACT-OARSI criteria)

2 years
Secondary outcome [2] 353907 0
Secondary outcome: stratifying variables (responder vs non responder) correlation between Melbourne MHIP MRI tendon Grading system scores at baseline and 2 years Responders will be determined by a Patient Acceptable Symptomatic State score (PASS Score) of >74 on the MHHS
Timepoint [2] 353907 0
2 years post treatment

Statistical methods / analysis
The sample size is expected to be 44 subjects. This is the number of RCT patients with pre-intervention MRI in the LR-PRP and crossover groups.
The data collected will be analysed using STATA statistical package. Significance will be p >0.05. Standard t-tests will be performed at each timepoint for comparison between groups.
