Low Tensile Strength Suture With Transosseous Tunnels and Suture Anchors 5 mm in Diameter or Greater Are Associated With Higher Failure Rates in Primary Patellar Tendon Repair.

Purpose: To determine the rate of and risk factors for clinical failure and return to military duty following primary patellar tendon repair with either transosseous trunnel repair or suture anchor repair. Methods: The Military Health System Data Repository (MDR) was queried to identify all adult patients undergoing surgical treatment of a patellar tendon rupture in the Military Health System from 2014 to 2018. Patients who underwent either transosseous tunnel repair or suture anchor repair were included. Health records were examined to collect additional data. Univariate analysis and multivariate logistic regression models were used to determine independent risk factors for rerupture. Results: A total of 450 knees in 437 patients were included. Transosseous tunnel repair was the most frequently used technique (314/450, 77%), followed by suture anchor repair (113/450, 25%). Rerupture occurred in 33 knees (7%). There was no difference in rerupture rate between transosseous tunnel repair and suture anchor repair (P = .15), and this result persisted within the multivariate logistic regression model. Among transosseous tunnel repairs, use of low tensile strength suture was an independent risk factor for repair failure (odds ratio [OR], 3.4; P = .016). Among suture anchor repairs, use of anchors 5.0 mm in diameter or greater (OR, 12.0; P = .027) was an independent risk factor for repair failure. Conclusions: There is no statistically significant difference in failure rate between transosseous tunnel repair and suture anchor repair in primary patellar tendon ruptures. However, the use of low tensile strength suture with transosseous tunnels and the use of suture anchors 5.0 mm in diameter or greater resulted in significantly higher failure rates. These data suggest that use of high tensile strength suture in transosseous tunnel repair and use of suture anchors less than 5.0 mm in diameter in suture anchor repair result in lower failure rate in primary patellar tendon repair. Level of Evidence: Level III, retrospective cohort study.

The Surgical Instrument Sterilization Process: What Every Surgeon Should Know.

¼ The phases of the sterilization process for surgical equipment are cleaning, disinfection, and sterilization.¼ Following manufacturer and regulatory guidelines will minimize contamination throughout the sterilization process.¼ Immediate use steam sterilization, when used appropriately, is a reasonably safe option to be used at the discretion of the operating surgeon.

Bony Edema and Clinical Examination Findings Predict the Need for Distal Clavicle Excision at the Time of Shoulder Arthroscopy.

Background: Deciding to perform a distal clavicle excision for acromioclavicular joint arthritis, especially in conjunction with other arthroscopic shoulder procedures, is challenging for surgeons. Studies have reported mixed results on the value of magnetic resonance imaging (MRI) in decision making. Purpose: We sought to correlate MRI findings with clinical symptoms and the surgeon's decision to perform a distal clavicle excision. Methods: We compared MRI, clinical examination, and MRI findings of 200 patients who underwent distal clavicle excision for symptomatic acromioclavicular joint arthritis with 200 patients who underwent arthroscopic shoulder procedures for other reasons. Univariate statistics were used to determine correlations between physical examination findings, MRI findings, and the decision to perform distal clavicle excision. A binary logistic regression model was used to determine independent predictors of need for distal clavicle excision. Results: There was no difference in mean age, sex, and race between groups. Advanced acromioclavicular joint osteoarthritis was strongly correlated with positive physical examination findings. Bony edema correlated strongly with tenderness at the acromioclavicular joint but not pain with cross-body adduction testing. There was no association between higher MRI grade of osteoarthritis and the need for distal clavicle excision. Regression analysis identified both physical examination findings and bony edema on MRI as independent predictors of the need for distal clavicle excision. Conclusion: In the setting of positive clinical examination findings and bony edema of the distal clavicle, surgeons should feel reassured that distal clavicle excision is likely indicated.

Opioid prescribing in the U.S. Military Health System, 2014 to 2018: fewer prescriptions, fewer pills, and shorter treatment duration.

ABSTRACT: Prescription opioids remain an important driver of the opioid crisis in the United States. The purpose of this study was to examine recent changes in opioid prescribing patterns in the Military Health System (MHS) which is a nationwide health system service active duty military personnel and civilian beneficiaries. All patients prescribed opioid analgesics by MHS providers and filled at MHS pharmacies between 2014 and 2018 were identified. Prescriptions were converted to oral morphine equivalents (OMEs) and categorized based on prescribing specialty and formulation. Total opioid prescription counts and opioid prescription counts weighted by the annual number of outpatient encounters for each specialty were calculated, as were total OMEs and daily OMEs per prescription. A total of 3,427,308 prescriptions were included. Primary care providers and surgeons wrote 47% and 29% of opioid prescriptions, respectively. Over the study period, there was a 56% decline in annual opioid prescriptions, 25% decline in median total OMEs, and a 57% decline in opioid prescriptions per patient encounter. The proportion of prescriptions written for >90 OMEs per day declined 21%. Declines in opioid prescriptions and quantities were observed in nearly all specialties over the study period. The results of this study suggest a broad-based shift towards less opioid prescribing.
