Plain English summary of protocol

Background and study aims
Steroid injection is a common treatment for musculoskeletal diseases. However, its effectiveness in functional ankle instability (FAI, a floppy loose ankle) is still controversial. The aim of this study is to find out whether a steroid and local anesthetic injection into the ankle improves ankle function more than health education.

Who can participate?
Patients aged 18 to 50 years with FAI

What does the study involve?
Participants are divided into two groups: the steroid group receives a steroid and local anesthetic injection, and the saline group receives a saline injection. For both groups, the follow-up is at 4, 8 and 12 weeks later.

What are the possible benefits and risks of participating?
Possible benefits include improvement in ankle function, and risks may include injection site infection and local soft tissue damage.

Where is the study run from?
Huashan Hospital, Fudan University (China)

When is the study starting and how long is it expected to run for?
January 2022 to January 2023

Who is funding the study?
National Natural Science Foundation of China

InterventionCurrent interventions as of 07/02/2023:

Randomization process: Patients are randomly assigned to two groups by an independent physician by choosing one of two sealed opaque envelopes. The allocation is performed by an independent researcher without knowing the treatment details.

Participants are divided into two groups: the steroid group receives an intra-articular steroid and local anesthetic injection (a mixture of 1 ml of 40 mg/ml triamcinolone and 2 ml 2% lidocaine) immediately after the baseline measurement, and the saline group receives a saline injection immediately after baseline measurement.

For both groups, the follow-up is at 4, 8 and 12 weeks after baseline measurement.

Previous interventions:

Randomization process: Patients are randomly assigned to Group A, B or C by an independent physician by choosing one of three sealed opaque envelopes containing letters A to C, reflecting the three groups, respectively. The allocation is performed by an independent researcher without knowing the treatment details.

Participants are divided into three groups: group A receives health education, group B receives an intra-articular steroid and local anesthetic injection (a mixture of 1 ml of 40 mg/ml triamcinolone and 2 ml 2% lidocaine) immediately after the baseline measurement, and group C receives a saline injection immediately after baseline measurement.

For all three groups, the follow-up is at 4, 8 and 12 weeks after baseline measurement.
