Knee Steroid Injection and Blood Sugar Signatur

Study Purpose

A prospective, observational study assessing the relationship between HbA1c level and the post-injection blood glucose signature. Participants will be non-diabetic, pre-diabetic, non-insulin dependent and insulin dependent type 2 diabetic patients who will be receiving a knee steroid injection. All of them will be consented a week prior to the injection, when the CGM sensor will be applied to the back of the upper arm. This will be removed a week after the injection. KOOS survey as well as VAS will be administered. Adverse events (e.g., change in medication or hospitalization) will be monitored throughout the study.

Recruitment Criteria

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.

An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.

Searching Both is inclusive of interventional and observational studies.

Trial Details

Trial ID:

This trial id was obtained from, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.


Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.
