Pain catastrophizing is associated with increased physical disability in patients with anterior knee pain.

INTRODUCTION: The traditional nociceptive approach to pain identifies the mind and body as functionally separate. However, the biopsychosocial model accounts for the impact of social, psychological and physical factors on the patient experience. The purpose of this study was to determine the relationship between diagnosis, physical disability, and psychological distress among patients with anterior knee pain-one of the most common complaints in an orthopedic clinic. METHODS: This was a single-center, cross-sectional study. Patients presenting for initial evaluation of knee pain completed the Pain Catastrophizing Scale, Kujala Anterior Knee Pain Scale, and SF-12 questionnaires. Statistical analysis was performed using SPSS Version 24. RESULTS: 207 patients, 108 (52.2%) females and 99 (47.8%) males, with a mean age 44.5 ± 15.4 years were enrolled. The osteoarthritis cohort had the highest pain catastrophizing score (17 ± 14.5), lowest Kujala score (48.3 ± 18.1), lowest SF-12 PCS (37.5 ± 8.3), and lowest SF-12 MCS (50.8 ± 11.0). Across all diagnoses, there was a statistically significant negative correlation between the total Pain Catastrophizing Score (PCS) and the Kujala, SF-12 Physical, and SF-12 Mental Component Scores. Bivariate and multivariate analysis demonstrated a correlation between PCS and duration of symptoms and African-Americans. The Kujala and SF-12 PCS demonstrated a statistically significant correlation with age, smoking, and the Asian Indian ethnicity. The SF-12 MCS showed a significant relationship with the Asian Indian ethnicity. Bivariate analysis also showed a statistically significant relationship between the SF-12 PCS and the SF-12 MCS. CONCLUSION: Knee pain patients presenting to an orthopedic sports medicine clinic demonstrate diminished physical quality of life and psychological reserves. This study determined an association between catastrophizing behavior and other patient reported outcomes measuring pain, physical distress, quality of life and mental/emotional well-being. To optimize patient outcomes, psychological domain should be managed contemporaneously to orthopedic pathology.

The Utility of Oral Nonsteroidal Anti-inflammatory Drugs Compared With Standard Opioids Following Arthroscopic Meniscectomy: A Prospective Observational Study.

PURPOSE: To evaluate the efficacy of oral nonsteroidal anti-inflammatory drugs (NSAIDs) as the primary postoperative pain medication compared with standard oral opioids following arthroscopic partial meniscectomy. METHODS: This was a single-center, prospective, nonrandomized, comparative observational study. Patients ages 18 to 65 years who were indicated for arthroscopic meniscectomy were included. Postoperatively, patients were prescribed 1 of 2 analgesic regimens: (1) ibuprofen (600 mg every 6-8 hours as needed) and 10 tablets of oxycodone/acetaminophen (5/325 mg as needed for breakthrough pain) or (2) 30 to 40 tablets oxycodone/acetaminophen (5/325 mg every 6 hours as needed). Subjects completed questionnaires at 8 hours, 24 hours, 48 hours, and 1 week after surgery, which included medication usage, visual analog scale pain score, incidence of adverse events, and patient satisfaction. RESULTS: Sixty-eight patients with mean age 51.2 years (±10.4 years) were enrolled between October 2016 and February 2017. Enrollment in the opioid group continued until 30 patients were enrolled in the NSAID group, and at final analysis there were 28 patients in the NSAID group and 40 in the opioid group. There were no significant differences in sex, visual analog scale pain score, or patient satisfaction between the 2 groups at any time point. Patients in the opioid group had a significantly higher mean opioid consumption on postoperative day 1 (1.1 vs 0.5 tablets, P < .03) and postoperative days 3 to 7 (2.6 vs 0.5 tablets, P < .02) compared with NSAID group patients. There was a trend toward greater total (1 week) opioid usage (4.7 vs 2.0 tablets) in the opioid group; however, this was not statistically significant (P < .08). Fifty-three percent of opioid group patients independently chose to forego their opioid medication for an over-the-counter NSAID and/or acetaminophen instead. No patients requested a medication refill. CONCLUSIONS: We found no significant difference in pain control, satisfaction, and total 1-week opioid use between patients prescribed NSAIDs with opioids and those prescribed opioids alone. All patients used only limited amounts of opioids to control postoperative pain, suggesting we are currently overprescribing opioids after arthroscopic partial meniscectomy. LEVEL OF EVIDENCE: Level II, prospective comparative study.

Acute pulmonary embolism after arthroscopic glenoid labral repair and subacromial decompression: case report and review of the literature.

This report describes the case of a 29 year-old female with a history of polycystic ovary syndrome (PCOS) and on combined oral contraceptives who presents with an acute, CT confirmed pulmonary embolus of the right lower lobe, one week following arthroscopic labral repair of the right shoulder. This patient's relevant risk factors including obesity, oral contraceptive use, PCOS, and surgical positioning are discussed. Literature surrounding venous thromboembolism (VTE) following shoulder arthroscopy is also reviewed.

Type IV hypersensitivity reactions following Dermabond adhesive utilization in knee surgery: A Report of Three Cases.

​We retrospectively reviewed the records of 3 patients (3 knees) with a delayed type hypersensitivity reaction following Dermabond exposure after an orthopaedic knee procedure. Delayed hypersensitivity reactions are mediated by CD4+ helper T cells. The use of skin adhesives in place of traditional sutures is increasing in popularity given Dermabond's potential benefits of decreased wound infection rate and better wound approximation. However, hypersensitivity reactions to the cyanoacrylate material in Dermabond have been described. Differentiating hypersensitivity reactions from post-operative infections is important as septic arthritis is a potentially devastating complication. This case series presents the challenge of properly diagnosing and managing hypersensitivity reactions. Consultation with allergists and dermatologists may be appropriate for ascertaining the nature of the surgical site complication and proper management. The recommended management of hypersensitivity-type reactions is a course of topical steroids and infection work up if needed.
