The impact of preoperative benzodiazepine use on postoperative opioid use in total shoulder arthroplasty.

BACKGROUND: As the rate of total shoulder arthroplasty (TSA) and preoperative benzodiazepine use rise, there is an increased need to understand the impact of preoperative benzodiazepine use on postoperative opioid consumption following TSA, especially amid the current opioid epidemic. The relationship between preoperative benzodiazepine use and chronic opioid use postoperatively has been well described following other orthopedic procedures; however, the impact on patients undergoing TSA remains unclear. This study aims to identify the impact of preoperative benzodiazepine use on opioid use following TSA. METHODS: A retrospective chart review of 4488 patients undergoing primary TSA (Current Procedural Terminology code 23472) at a single institution from 2014 to 2022 was performed. Patient demographics, surgical variables, comorbidities, Distressed Communities Index (DCI), and clinical outcomes, including readmission and revision, were collected. The Charlson Comorbidity Index (CCI) was used to assess preoperative health status. Opioid use in morphine milligram equivalents (MMEs) and benzodiazepine use were also recorded using the Prescription Drug Monitoring Program Database. Opioid use was collected at 30-, 60-, and 90-day intervals both before and after each patient's date of surgery. Statistical analysis included stepwise logistic regression to identify variables independently affecting benzodiazepine use pre- and postoperatively. RESULTS: Overall, 16% of patients used benzodiazepines within 90 days before their date of surgery. Of those patients, 46.4% were also using preoperative opioids, compared with just 30.0% of patients who were benzodiazepine-naïve (P < .001). Preoperative benzodiazepine use was also associated with increased pre- and postoperative total opioid use in MMEs and the number of opioid prescriptions across all time points when compared to benzodiazepine-naïve patients (P < .001). Furthermore, 37.4% of preoperative benzodiazepine users went on to prolonged opioid use (filled prescriptions >30 days after surgery) compared to 19.0% of those who were benzodiazepine-naïve (P < .001). CONCLUSION: This study demonstrates a significant association between preoperative benzodiazepine use and increased and prolonged opioid use following TSA. Further exploration of risk factors contributing to preoperative benzodiazepine use may help to reduce overall opioid use in patients undergoing TSA.

ChatGPT Provides Unsatisfactory Responses to Frequently Asked Questions Regarding Anterior Cruciate Ligament Reconstruction.

PURPOSE: To determine whether the free online artificial intelligence platform ChatGPT could accurately, adequately, and appropriately answer questions regarding anterior cruciate ligament (ACL) reconstruction surgery. METHODS: A list of 10 questions about ACL surgery was created based on a review of frequently asked questions that appeared on websites of various orthopaedic institutions. Each question was separately entered into ChatGPT (version 3.5), and responses were recorded, scored, and graded independently by 3 authors. The reading level of the ChatGPT response was calculated using the WordCalc software package, and readability was assessed using the Flesch-Kincaid grade level, Simple Measure of Gobbledygook index, Coleman-Liau index, Gunning fog index, and automated readability index. RESULTS: Of the 10 frequently asked questions entered into ChatGPT, 6 were deemed as unsatisfactory and requiring substantial clarification; 1, as adequate and requiring moderate clarification; 1, as adequate and requiring minor clarification; and 2, as satisfactory and requiring minimal clarification. The mean DISCERN score was 41 (inter-rater reliability, 0.721), indicating the responses to the questions were average. According to the readability assessments, a full understanding of the ChatGPT responses required 13.4 years of education, which corresponds to the reading level of a college sophomore. CONCLUSIONS: Most of the ChatGPT-generated responses were outdated and failed to provide an adequate foundation for patients' understanding regarding their injury and treatment options. The reading level required to understand the responses was too advanced for some patients, leading to potential misunderstanding and misinterpretation of information. ChatGPT lacks the ability to differentiate and prioritize information that is presented to patients. CLINICAL RELEVANCE: Recognizing the shortcomings in artificial intelligence platforms may equip surgeons to better set expectations and provide support for patients considering and preparing for ACL reconstruction.

Metacarpal Fracture Repair: Early Reoperation Rates and Characteristics.

Purpose: Metacarpal fractures are common injuries of the hand that often require operative repair. However, there is a paucity of data regarding the rate of reoperation and circumstances following metacarpal repair. Methods: A retrospective review of all metacarpal fracture cases performed at a single academic institution between 2017 and 2021 was performed. All patients with isolated, acute metacarpal fractures were included for review. Data on patient demographics, fracture morphology, surgical technique, rate of early reoperation, and reason for reoperation were collected. Results: A total of 499 patients were identified to have undergone operative treatment for an isolated metacarpal fracture with an average follow-up of 4.2 months. The rate of unplanned early reoperation was 8.0% (n = 40), with seven patients requiring revision fracture surgery and 33 patients undergoing removal of symptomatic hardware. Mean and median time to reoperation was 2.1 and 1.5 months, respectively. The rate of reoperation for fractures of the metacarpal shaft was significantly lower than that of other fracture locations. Among the 40 revision cases, one case was following percutaneous fixation while 39 cases were following open reduction and internal fixation. Other demographic factures and fracture characteristics failed to show significant correlations to the rate of reoperation. Conclusions: An unplanned early reoperation rate of 8.0% after operative fixation of acute metacarpal fractures was observed with the majority involving cases of removal of symptomatic hardware and an average time to reoperation of approximately 2.1 months. This information can be used to counsel patients and set expectations about the potential for metacarpal fracture surgeries. Type of Study/Level of Evidence: Prognosis 2b.

Incidence of Complications and Revision Surgery After High Tibial Osteotomy: A Systematic Review.

BACKGROUND: High tibial osteotomy (HTO) is a well-recognized procedure for its effectiveness in treating symptomatic early knee arthritis and malalignment. Although there are numerous systematic reviews evaluating the management and outcomes after HTO, there are few investigations on complications of this procedure. PURPOSE: To systematically review the literature to determine the incidence of intraoperative and postoperative complications associated with medial opening wedge and lateral closing wedge HTOs. STUDY DESIGN: Systematic review; Level of evidence, 4. METHODS: The Cochrane Database of Systematic Reviews, PubMed, Embase, and MEDLINE databases were queried for studies reporting complications associated with HTO with or without concomitant procedures. Data including patient characteristics, procedure type, concomitant procedures, follow-up time, and postoperative imaging were extracted. Rates of intra- and postoperative complications, reoperations, and conversion to arthroplasty were recorded. RESULTS: A total of 71 studies were included for analysis, comprising 7836 patients. The overall intraoperative complication rate during HTO was 5.5% (range, 0%-29.3%), and the overall postoperative complication rate was 6.9% (range, 0%-26.6%). The most common intraoperative complication was lateral hinge fracture (incidence, 9.1%; range, 0%-30.4%) in medially based HTOs and peroneal nerve injury in laterally based HTOs (incidence, 3.2%; range, 0%-8.7%). The overall incidence of neurovascular injury after medially or laterally based HTOs was 1.1% (range, 0%-18.9%). The most common postoperative complication was superficial infection (incidence, 2.2%; range, 0%-13%). Of the included studies, 62 included postoperative radiographic analysis, and among those, the incidence of nonunion was 1.9% (range, 0%-15.5%), loss of correction was 1.2% (range, 0%-34.3%), and implant failure was 1.0% (range, 0%-10.2%). Among studies reporting revision surgeries, the overall reoperation rate was 15.5% (range, 0%-70.7%), with the most common type of reoperation being hardware removal (incidence, 10.0%; range, 0%-60%). CONCLUSION: Intraoperatively, medially based HTOs are associated with a 1 in 11 risk of lateral hinge fracture and laterally based HTOs with a 1 in 30 risk of peroneal nerve injury. Postoperative complication rates in the range of 10% to 15% can be expected, including infection (2.9%), loss of correction (1.2%), and nonunion (1.9%). Patients should also be counseled that the reoperation rate is approximately 15%, with hardware removal being the most common procedure.

High Levels of Satisfaction and Adequate Patient-Reported Outcomes After Operative Reconstruction of Multiligament Knee Injury With Allograft Among Patients Aged 40 Years and Older.

Purpose: To describe injury characteristics and patient-reported outcomes (PROs) among patients aged 40 years and older who underwent allograft reconstruction for multiligament knee injury (MLKI). Methods: Records of patients aged 40 years and older who underwent allograft multiligament knee reconstruction at a single institution between 2007 and 2017 with a minimum of 2 years of follow-up were retrospectively reviewed. Demographic information, concomitant injuries, patient satisfaction, and PROs including International Knee Documentation Committee and Marx activity scores were obtained. Results: Twelve patients were included with a minimum follow-up time of 2.3 years (mean, 6.1; range, 2.3-10.1 years) and a mean age at surgery of 49.8 years. Seven patients were male, and the most common mechanism of injury was sport-related. The most frequently reconstructed MLKIs were anterior cruciate ligament and medial collateral ligament (4), anterior cruciate ligament and posterolateral corner (2), and posterior cruciate ligament and posterolateral corner (2). The majority of patients reported satisfaction with their treatment (11). Median International Knee Documentation Committee and Marx scores were 73 (interquartile range, 45.5-88.0) and 3 (interquartile range 0-5), respectively. Conclusions: Patients aged 40 years and older can expect a high level of satisfaction and adequate PROs at 2-years follow-up after operative reconstruction for a MLKI with allograft. This demonstrates that allograft reconstruction for a MLKI in older patients may have clinical utility. Level of Evidence: IV, therapeutic case series.

Revision Soft-Tissue Allograft Anterior Cruciate Ligament Reconstruction Is Associated With Lower Patient-Reported Outcomes Compared With Primary Anterior Cruciate Ligament Reconstruction in Patients Aged 40 and Older.

PURPOSE: To evaluate patient-reported outcomes (PROs) and graft failure rates in revision allograft anterior cruciate ligament reconstruction (ACLR) in patients aged 40 and older and compare them with primary ACLRs. METHODS: Patients aged 40 and older who underwent arthroscopic soft-tissue allograft ACLR between 2005 and 2016 with a minimum 2-year follow-up were retrospectively reviewed. Patients were grouped based on revision versus primary ACLR. The rate of achieving an International Knee Documentation Committee (IKDC) patient acceptable symptom state (PASS) score was recorded. Patient satisfaction, PROs, and graft failure were compared between groups using the χ2 test, Fisher exact test, and Mann-Whitney U test. RESULTS: We identified 32 patients who underwent revision ACLR and 201 patients who underwent primary ACLR aged 40 and older who met inclusion criteria with a mean follow-up of 6.2 and 6.9 years, respectively (P = .042). There was a lower rate of concomitant meniscal repair in the primary ACLR group (6% vs 21.9%, P = .007) There were no other differences in chondral injuries, mechanism of injury, or meniscal injuries between groups. The median IKDC score was greater in the primary ACLR group as compared with the revision ACLR group (83.9 vs 70.6, P < .001). Patients who underwent revision ACLR were less likely to achieve the IKDC PASS threshold (82.5% vs 56.3%, P = .001) and were less likely to report satisfaction as compared with patients who underwent primary ACLR (90.5% vs 78.1%, P =.038). No difference in graft failure rates was identified between groups (8% vs 15.6%, P = .180). CONCLUSIONS: Revision allograft ACLR in patients aged 40 and older was associated with lower PROs compared with primary ACLR. Patients who underwent revision ACLR failed to meet the IKDC PASS threshold more often and were dissatisfied with procedure results more than twice as often as patients that underwent primary ACLR. LEVEL OF EVIDENCE: III, retrospective cohort study.

Fracture dislocations of the proximal humerus treated with open reduction and internal fixation: a systematic review.

BACKGROUND: The treatment of proximal humerus fracture dislocations can be challenging given the extensive injury to the proximal humeral anatomy and increased risk of devascularization of the humeral head often seen in these injuries. The purpose of this study is to undertake a systematic review of the literature on the functional outcomes, rate of revision, and short- and long-term complications for proximal humerus fracture dislocations treated with open reduction and internal fixation (ORIF). METHODS: The PubMed and OVID Embase databases were queried for literature reporting on proximal humerus fracture dislocations treated with ORIF. Data including study design, patient demographics, functional outcomes, and complications were recorded. RESULTS: Twelve studies including 294 patients with Neer type 2-, 3-, or 4-part proximal humerus fracture dislocations met the criteria for inclusion. The mean patient age was 53.4 years (19-89 years) with an average follow-up of 2.9 years (1.15-4.9 years). At the final follow-up, the mean Constant score was 73.2 (52-87.3) and the mean Disabilities of the Arm Shoulder and Hand score was 26.6 (17.5-32). Avascular necrosis was observed in 20.0% (0%-82.3%) and nonunion was observed in 3.0% (0%-7.7%) of patients. Conversion to arthroplasty was observed in 10.7% (5%-20%) and a total reoperation was observed in 35.6% (11.8%-89.1%) of patients in studies explicitly reporting these outcomes. In addition to conversion to arthroplasty, common causes of reoperation were revision ORIF (5.2%) and hardware removal (22.2%). CONCLUSION: Patients undergoing ORIF for proximal humerus fracture dislocations have reasonable functional outcomes but relatively high avascular necrosis and reoperation rates. This information can be used to counsel patients and set expectations about the potential for further surgeries.

The Majority of Patients Aged 40 and Older Having Allograft Anterior Cruciate Ligament Reconstruction Achieve a Patient Acceptable Symptomatic State.

PURPOSE: To evaluate patient satisfaction, retear rates, and patient-reported outcomes (PROs) in patients aged 40 and older undergoing allograft anterior cruciate ligament reconstruction (ACLR). The secondary goal was to compare these parameters between groups of patients with intact versus failed grafts, and to evaluate these in relation to a historically reported International Knee Documentation Committee (IKDC) patient-acceptable symptoms state (PASS) score. METHODS: Records of patients aged 40 and older who underwent ACLR between 2005 and 2016 at a single institution with a minimum 2-year follow-up were retrospectively reviewed. Patient-reported satisfaction, outcome scores, and failure rates were analyzed. The rate of achieving a previously defined IKDC PASS score based on younger cohorts was reported, and an updated PASS threshold for older patients was calculated. RESULTS: 201 patients were included with a mean age of 48.6 years (range: 40-68) and mean follow-up of 6.2 years (range: 2.8-11.2). 182 (90.5%) patients reported satisfaction following surgery. 16 (8.0%) patients experienced failure of their ACLR, 10 of which underwent revision ACLR. The median IKDC score in the intact ACLR group was 86.2, compared to 66.7 in the failure group (P < .001). In total, 134 (72.4%) patients in the intact group achieved the historical PASS score of 75.9 on IKDC compared to only 4 (25%) in the failure group (χ2 = 15.396, P < .001). An updated IKDC PASS threshold for older cohorts was calculated to be 66.7. CONCLUSION: Patients aged 40 and older who underwent allograft ACLR had an 8.0% failure rate at a mean follow-up of 6 years. Graft failure in patients aged 40 and older was associated with worse PROs. The majority of patients achieved the historically reported IKDC PASS threshold. Additionally, an updated age-appropriate IKDC PASS score of 66.7 was calculated to aid in future ACLR studies assessing older patients. STUDY DESIGN: Level IV.
