NCT04082533

Brief Summary

In this study, total knee replacement patients will be determined to be stiff or non-stiff preoperatively. Stiffness designation is determined by preoperative range of motion (if flexion is \< 100 degrees, or extension lag is \> 10 degrees). The stiff and non-stiff groups will both be randomized to two groups to receive either intravenous hydrocortisone or a placebo at 3 intervals postoperatively. Patients will be followed up with in hospital and via the phone on postoperative day (POD) 1 and 2, as well as 6 weeks, 6 months, 1 year, and 2 years postoperatively. Patients will also have blood drawn preoperatively in the OR, on POD1, at their 6 week followup, and at their 1 and 2 year follow ups. This blood will be processed and analyzed.

Study Arms (4)

Stiffness Intravenous Hydrocortisone

ACTIVE COMPARATOR

Total knee replacement patients with preoperative knee stiffness (defined as flexion \< 100 degrees or extension lag \> 10 degrees) receive 3 doses of 100mg intravenous hydrocortisone every 8 hours. The first dose is given in the holding area approximately 2 hours prior to first incision.

Drug: Hydrocortisone

Stiffness Intravenous Placebo

PLACEBO COMPARATOR

Total knee replacement patients with preoperative knee stiffness (defined as flexion \< 100 degrees or extension lag \> 10 degrees) receive 3 doses of matched volume diluent every 8 hours. The first dose is given in the holding area approximately 2 hours prior to first incision.

Drug: Dextrose 5% in water (D5W)

Non-stiff Intravenous Hydrocortisone

ACTIVE COMPARATOR

Total knee replacement patients without preoperative knee stiffness (defined as flexion \< 100 degrees or extension lag \> 10 degrees) receive 3 doses of 100mg intravenous hydrocortisone every 8 hours. The first dose is given in the holding area approximately 2 hours prior to first incision.

Drug: Hydrocortisone

Non-stiff Intravenous placebo

PLACEBO COMPARATOR

Total knee replacement patients without preoperative knee stiffness (defined as flexion \< 100 degrees or extension lag \> 10 degrees) receive 3 doses of matched volume diluent every 8 hours. The first dose is given in the holding area approximately 2 hours prior to first incision.

Drug: Dextrose 5% in water (D5W)

Interventions

Patients will be receiving 100 mg intravenous hydrocortisone every 8 hours, starting in the holding area roughly 2 hours prior to first incision.

Non-stiff Intravenous HydrocortisoneStiffness Intravenous Hydrocortisone

Patients will be receiving a matched volume of D5W every 8 hours, starting in the holding area roughly 2 hours prior to first incision.
