NCT06936709

Brief Summary

This study is a prospective, randomized, double-blinded, placebo-controlled study of the drug colchicine in the acute postoperative period for patients who are undergoing a total knee arthroplasty (TKA). Patients aged 18 years or older who are undergoing TKA will be invited to participate in the study. The primary endpoint of this study is to determine if colchicine, an anti-inflammatory medication commonly used for gout attacks, will decrease the postoperative pain of patients undergoing elective TKA.

Outcome Measures

Primary Outcomes (1)

  • Postoperative VAS pain score

    Subjects will receive a post-operative pain journal upon hospital discharge on postoperative day 0. The journal will include three time points (morning, midday, and bedtime) in which they will record a VAS pain score ranging from 0-10 for post-operative days 1-3. 0 being no pain, 10 being the worst pain they have ever experienced.

    From postoperative day 0 through postoperative day 4.

Secondary Outcomes (5)

  • Daily Opioid Usage

    From postoperative day 0 through postoperative day 3.

  • Postoperative KOOS-JR Score

    From postoperative day 0 through postoperative week 12.

  • Postoperative Knee Flexion

    Postoperative day 0 through postoperative week 12.

  • 90 day postoperative complications

    Postoperative day 0 to postoperative day 90

  • Colchicine Related Side Effects

    Postoperative day 0 through postoperative day 3.

Study Arms (3)

Colchicine Loading Dose Only

EXPERIMENTAL

Patients in this arm will receive 1.8 mg of colchicine on postoperative day 0. This dosage aligns with standard of care loading dose for acute gout attacks. This will be a one time dosage of colchicine. On postoperative days 1-3, patients will take placebo dextrose pills twice daily.

Drug: Colchicine 1.8 mg (loading dose) + Dextrose Oral Placebo

Colchicine Loading Dose + Maintenance Dose

EXPERIMENTAL

Patients in this arm will receive a 1.8 mg loading dose of colchicine on postoperative day 0. They will then take a 0.6 mg maintenance dose twice daily on postoperative days 1-3. This dosage of colchicine in this arm models standard of care dosing for acute gout attacks.

Drug: Colchicine 1.8 mg + 0.6 mg

Placebo Group

PLACEBO COMPARATOR

Patients in this arm will receive a placebo dextrose pill on postoperative day 0. They will then take a placebo dextrose pill twice daily on postoperative days 1-3.

Drug: Dextrose Oral Placebo

Interventions

This intervention will be used for individuals in arm A of the study who will receive a loading dose of colchicine (1.8 mg) on postoperative day 0, and will then be given placebo oral dextrose pills to take twice daily on postoperative days 1-3

Colchicine Loading Dose Only

This intervention is will be given to patients in arm B of the study who will receive a loading dose of colchicine (1.8 mg) on postoperative day 0, followed by a maintenance does of colchicine (0.6 mg) to be taken twice daily on postoperative days 1-3.

Colchicine Loading Dose + Maintenance Dose

This intervention will be for patients in arm C, the placebo arm. These patients will receive oral dextrose pills to be taken once on postoperative day 0, and twice daily on postoperative days 1-3.
