Knee Steroid Injection and Blood Sugar Signatur

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.
