Opioid Use After Knee Arthroscopy in Adolescent Patients: A Prospective Evaluation.

Background: There is a relative paucity of literature on how to best treat postoperative pain after knee arthroscopy in the adolescent population.

Purpose: To evaluate the use of opioid medication after knee arthroscopy in adolescent patients.

Study Design: Case series; Level of evidence, 4.

Methods: We prospectively enrolled 50 patients aged 10 to 18 years who underwent 1 of the following procedures: diagnostic arthroscopy; plica excision; loose body removal; debridement; chondroplasty; meniscal repair; and/or partial meniscectomy. Patients already taking chronic pain medication and those undergoing revision knee arthroscopy, ligamentous reconstruction, or bony osteotomy procedures were excluded. Postoperatively, the patients were prescribed 15 tablets of hydrocodone/acetaminophen (5 mg/325 mg) every 6 hours as needed for pain. The patients were given a diary to record the number of postoperative opioid pills taken, days the pills were taken, pain level, and nonopioid pills taken. The data were collected and used to identify the mean number of opioid pills needed as well as the number of days opioid medication was needed postoperatively.

Results: Of the 50 enrolled patients, 35 patients adequately completed the diary and were included in the study. The mean age in this cohort was 14.2 years. The total number of pills taken ranged from 0 to 14, with an overall mean of 5.41. Therefore, on average, patients utilized 36% of their postoperative prescriptions. In our cohort, 74.3% of patients had stopped taking opioids by postoperative day 3, with a mean of 3.8 pills, and 97.1% of patients had stopped taking opioids by postoperative day, 5 with a mean of 5.3 pills. No postoperative refills of opioid medication were necessary.

Conclusion: After knee arthroscopy, the adolescents in our study consumed a mean of 5.41 opioid pills postoperatively, and over 97% of patients stopped opioid use by postoperative day 5. The results of this study should help in guiding physicians to avoid overprescribing opioid medication while treating postoperative pain after knee arthroscopy in this vulnerable patient population.
