COVID-19 studies are our top priority. For all other studies, we recommend commencing the registration process concurrently with your ethics submission and allowing at least 8 weeks for registration to be completed from date of first submission as we are experiencing 4 week turn-around time in review of submissions and resubmissions. We currently do not have the capacity to expedite reviews.

Note also there are additional delays to review of updates. We appreciate your patience.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Study type
Description of intervention(s) / exposure
A single platelet-rich plasma (PRP) injection (Biomet Biologics), injected intra-tendonously. This will be performed only once during the trial. Patents receiving the PRP procedure will have 55 mls of blood taken. The blood is placed in a balanced centrifuge and spun for 15 minutes. The resulting 7 mL (approx) of platelet-rich plasma is then injected.
Intervention code [1] 285393 0
Treatment: Other
Comparator / control treatment
A single injection of Celestone Chronodose (cortisone), 5.7ml as a single dose, injected intra-tendonously. Patients receiving the Cortisone treatment will have 55 mls blood taken.
Control group

Primary outcome [1] 287653 0
Change from baseline in Modified Harris Hip Score, assessing patient ratings of hip function, pain and activity.
Timepoint [1] 287653 0
12 weeks post-intervention
Secondary outcome [1] 298585 0
Safety - occurrence of adverse events. Patients will be asked about possible adverse events at each patient follow-up, and also encouraged to report them to the investigators at any time during the trial. No adverse events have been pre-specified as likely.
Timepoint [1] 298585 0
Throughout the trial, in particular at each patient follow-up. Patients will be asked about possible adverse events, and also encouraged to report them to the investigators at any time during the trial. Follow-up of patients will take place 2 weeks, 6 weeks, 3 months and 12 months post-treatment. Total planned trial duration is 12 months.

Minimum age
18 Years
Maximum age
80 Years
Both males and females
Can healthy volunteers participate?

Study design
Purpose of the study
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Allocation is concealed. All subjects will have blood taken. This will be spun to yield the PRP, or the blood is discarded depending on the allocation. The PRP or Cortisone will be presented concealed.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Randomisation sequence was generated with PROC PLAN (SAS procedure). Block randomisation was used.
Masking / blinding
Blinded (masking used)
Who is / are masked / blinded?

Brief summary
The trial's main purpose is to test the effectiveness of platelet-rich plasma (PRP) injections in patients who have painful gluteal tendonopathies. The trial aims to see if PRP use in patients who have gluteal tendonopathies reduces pain and improves functional levels at 12 weeks follow-up, compared to cortisone injection. No data exist on the use of PRP in gluteal tendonopathies. A small, uncontrolled study carried out by the investigators showed promising results. Therefore we want to study the use of PRP injections in patients with gluteal tendonopathy prospectively, in a double-blind randomised, controlled trial.
