Brief summary

The purpose of this study is to determine if ceftriaxone administered postoperatively via intravenous injection reduces postoperative visual analog scale (VAS) pain scores and narcotic consumption in patients undergoing knee arthroscopy for a cartilage or meniscal injury.

Detailed description

Arthroscopic surgery for cartilage and meniscus injuries are some of the most common orthopaedic procedures currently performed. Post-surgical pain is initiated through an inflammatory response to surgery. The pain response leads to sleep disruption and a further increase in pain and additional sleep disruption. Opioid medications are often used after surgery to treat pain despite the side effect profile. These medications also contribute to poor sleep quality and duration. Early pain and narcotic use can be controlled by mitigating the effects of post-surgical inflammation. Ceftriaxone is a readily available antibiotic and may have the desirable anti-inflammatory and analgesic effects, but without the side effects caused by other medications. Since it is highly selective in its inhibition, ceftriaxone is an excellent candidate for reducing immediate post-operative pain and heightened inflammatory response. By doing this study, the investigators hope to learn about the anti-inflammatory effectiveness of the antibiotic ceftriaxone. Ceftriaxone has been shown to inhibit a key enzyme in the post-operative inflammatory process and has been safely used for treatment of infections for years. The investigators would like to gather information about whether ceftriaxone helps reduce pain and inflammation after surgery. Participation in this research will last about 2 months.

QUADRUPLE (Subject, Caregiver, Investigator, Outcomes Assessor)

Masking description

One group will receive an intravenous dose of ceftriaxone and the other will receive an intravenous dose of lidocaine in saline. The syringes will be blinded to ensure that both the investigator administering the injection and the patient will be blinded to the group assignment.

Intervention model description

After providing informed consent, patients undergoing arthroscopy of the knee for meniscal or cartilage injuries will be randomized into one of two groups. At the time of surgery, while the patient is under anesthesia, one group will receive a single intravenous dose of 1 gram of ceftriaxone and the other will receive a single intravenous dose of 1% lidocaine in saline.

Design outcomes

Primary

MeasureTime frameDescription
Change in Visual Analog Scale (VAS) Pain ScorePre-operative, 2 months post-operativeThe Visual analog scale scores range from 0 to 10 with greater scores indicative of greater pain.
Change in RU SATED ScorePre-operative, 2 months post-operativeThe Regularity, Sleep Quality, Alertness, Timing, Efficiency, Duration scale for sleep (RU SATED) ranges from 0 to 30, with higher scores indicating better sleep health.
Post-operative Narcotic Use5-12 days post-operativePost-operative narcotic use will be monitored with self-reported medication consumption at the first post-operative visit, which will take place 5-12 days post-operative. The milligrams of morphine equivalent (MME) will be calculated based on patient responses with greater MME indicative of increased postoperative use of narcotic pain medications.
