Background: When coronavirus disease 2019 (COVID-19) first spread to the United States, our institution was at the outbreak's epicenter. Despite limited understanding of COVID-19's long-term effects, we continued performing surgical fixation of geriatric hip fractures under strict guidelines. This study examined the outcomes of these patients during the pandemic compared with those of patients treated pre-pandemic.

Materials and methods: We conducted a retrospective cohort study of patients with hip fractures between December 2019 and June 2020, the peak of the pandemic in our region. Outcomes of patients treated with surgical fixation (2020 cohort) were compared with those of a historical control group (2019 cohort). The primary outcome was 90-day mortality, with secondary outcomes including pneumonia, thromboembolic events, emergency department visits, readmission, and cardiac events.

Results: The 2020 cohort (n=64) and 2019 cohort (n=78) had similar baseline characteristics. The 2020 cohort had a 4.27 times higher risk (95% CI, 1.30-13.98) of developing pneumonia compared with the pre-pandemic cohort but had no other differences in 90-day complications. Patients with COVID-19 in the 2020 cohort had a 5.09 times higher risk (95% CI, 1.35-19.20) of developing pneumonia and a 5.38 times higher risk (95% CI, 1.13-25.64) of postoperative mortality. There was no increased risk for thromboembolism between the 2020 and 2019 cohorts, even among COVID-19 cases, as all patients received anticoagulation with heparin.

Conclusion: Our study demonstrates that hip fracture surgery remained safe during the peak of the US COVID-19 pandemic, with an expected increase in pneumonia and mortality risk for patients with hip fracture with COVID-19. [Orthopedics. 2024;47(6):359-364.].

Background: Although the Latarjet operation may be performed as a revision surgery for anterior shoulder instability, the high recurrence rate of anterior shoulder instability after arthroscopic Bankart repair (ABR) has led some to advocate for performing the Latarjet procedure as a primary stabilization surgery. The purpose of this study was to compare the intermediate-term outcomes after primary open Latarjet (PLJ) and revision to open Latarjet (RLJ).

Materials and methods: This was a single-institution retrospective analysis of patients who underwent either PLJ or RLJ procedures for anterior shoulder instability between 2014 and 2023. Patients with less than 1 year of follow-up, seizure history, multidirectional instability, concurrent rotator cuff repair, or the absence of preoperative imaging were excluded. Glenoid bone loss (GBL), the width of Hill-Sachs lesions, recurrent dislocations, and reoperations were assessed.

Results: The study included 29 patients, with 12 undergoing PLJ procedures and 17 undergoing RLJ procedures. The mean duration of follow-up was similar for the two groups (4.7 vs 4.6 years, P=.854). Patients undergoing PLJ procedures demonstrated a higher mean GBL (18.4%) compared with patients undergoing revision (10.5%; P=.035); however, there was no significant difference in Hill-Sachs lesion size (14.2 vs 10.4 mm, P=.374). After stratifying according to GBL, the groups undergoing PLJ and RLJ procedures had similar recurrent dislocation rates (8.3% and 11.8%, respectively; P=1.0) and reoperation frequency (25.0% and 23.5%, respectively; P=1.0).

Conclusion: The PLJ and RLJ groups had comparable rates of recurrent dislocations, complications, and reoperations, emphasizing the value of considering Latarjet procedures as revision surgery after unsuccessful primary arthroscopic stabilization. [Orthopedics. 2024;47(6):343-348.].

Background: This study compared perioperative outcomes as well as encounter and 90-day costs between patients undergoing traditional vs robotic total knee arthroplasty (rTKA).

Materials and methods: A total of 430 TKAs (215 rTKAs, 215 traditional) were retrospectively reviewed. All rTKAs were performed with an imageless, second-generation robotic system. Cohorts were propensity score matched by age, sex, body mass index, and American Society of Anesthesiologists score. Perioperative data and 90-day complications were subsequently compared. Cox regression analyses evaluated survival to all-cause revisions. Univariable analyses compared total cost of care for the initial encounter and 90-day postoperative period. Multivariable regression analyses were then performed to evaluate associations with increased encounter and 90-day costs.

Results: Patients undergoing rTKA had a higher incidence of discharge home (86.5% vs 60.0%; P<.001). The rTKA cohort trended toward a lower incidence of 90-day emergency department visits, and there was a significantly lower percentage of 90-day readmissions (4.2% vs 13.5%; P=.001). Cox hazard ratio demonstrated no difference in survival to all-cause revisions (hazard ratio, 1.3; 95% CI, 0.5-3.7; P=.64). The cost of surgery was significantly higher in the rTKA cohort ($9292 vs $8392; P<.001); however, there was no difference in cost of encounter ($10,356.86 vs $10,396.44; P=.110) or at 90 days postoperatively ($11,103.89 vs $11,040.13; P=.739). rTKA did not have a significant association with increased cost at 90 days postoperatively (odds ratio, 0.96; 95% CI, 0.90-1.02; P=.180).

Conclusion: rTKA had a higher intraoperative cost compared with traditional TKA. However, with increased home discharges and fewer 90-day readmissions, rTKA was not associated with increased cost at 90 days. [Orthopedics. 2024;47(6):365-371.].

Background: The purpose of this study was to evaluate the impact that obesity, smoking, and older age have on 30-day postoperative complications, reoperations, and readmissions of patients undergoing arthroscopic meniscectomy or meniscus repair.

Materials and methods: The American College of Surgeons National Surgical Quality Improvement Program (NSQIP) database was queried to identify meniscus surgeries and operative outcomes between 2008 and 2016. Controlled regression analysis was then performed to evaluate for an association between obesity, age, and smoking and these outcomes.

Results: While obesity showed no influence on adverse postoperative complications or reoperations, class I obesity was associated with a lower rate of readmission. Older age, smoking, and comorbidity burden were significant predictors of postoperative complications, reoperations, and/or readmissions. Age 80 years or older was particularly predictive of 30-day complications (odds ratio, 3.5; P<.001) and readmissions (odds ratio, 2.5; P=.004).

Conclusion: Obesity is not a major risk factor for complications when undergoing meniscus surgery, while age older than 70 years predicts negative short-term postoperative outcomes. [Orthopedics. 2024;47(6):332-336.].

Background: Lumbar spine fractures are common injuries associated with substantial morbidity for patients and socioeconomic burden. This study sought to epidemiologically analyze lumbar spine fractures by mechanism of injury and identify temporal trends in patient demographics and disposition, which few studies have previously evaluated.

Materials and methods: A retrospective analysis was done of the US National Electronic Injury Surveillance System (NEISS) database between 2003 and 2022. The sample contained all patients 2 to 101 years old with product-related lumbar fractures presenting to participating institutions' emergency departments. A total of 15,196 unweighted injuries (642,979 weighted injuries) were recorded.

Results: Overall, there was a 20-year incidence rate of 10.14 cases per 100,000 person-years with a 2-fold increase in fracture incidence. Females were more prone to lumbar fracture than males (P=.032). Injuries primarily stemmed from a fall (76.6%). The incidence of lumbar fracture increased most significantly in older patients, with patients 80 years and older showing the greatest annual increase (β=8.771, R²=0.7439, P<.001) and patients 60 to 69 years showing the greatest percent increase with a 3.24-fold increase in incidence. Most (58.9%) of the fractures occurred at home. Females were more often injured at home compared with males (P<.001), who more often sustained lumbar fractures during recreational or athletic activity (P<.001). All patients older than 40 years showed at least a doubling in incidence rate of lumbar fracture between 2003 and 2022.

Conclusion: These data demonstrate the pressing need to address poor bone health in the aging population, shown here to have an increasing fracture burden. [Orthopedics. 2024;47(6):e297-e302.].

Background: We conducted a study to investigate the relationship between a mental health diagnosis (MHD) and postoperative outcomes in orthopedic patients with bone and soft tissue sarcoma. We hypothesized that patients with sarcoma with a preoperative MHD would have worse outcomes and more postoperative complications.

Materials and methods: A retrospective review was performed of 356 patients who underwent surgical treatment for bone or soft tissue sarcoma. Patients were divided into two groups: those with a diagnosis of depression, anxiety, bipolar disorder, and/or schizophrenia and those with no previous MHD. Statistical analysis was performed using independent t, Mann-Whitney U, and chi-square tests.

Results: Statistical analysis demonstrated significant differences between the MHD group and the control group in three outcomes: length of stay, 90-day readmission rate, and incidence of surgical site infections. Subgroup analysis of the MHD group yielded significantly higher 90-day readmission rates for patients who were diagnosed during sarcoma treatment.

Conclusion: Patients with sarcoma and an MHD had a longer postoperative hospital stay, an increased 90-day readmission rate, and a greater risk of surgical site infection. Given the rising prevalence of mental health disorders nationwide, orthopedic surgeons should be aware of differences in postoperative outcomes between patients with sarcoma with and without mental illness.

Eponyms are widely used in the field of orthopedic surgery, including for surgical instruments. Although their use is at times controversial, an appreciation of the history behind eponymous terms allows one to both recognize the shortcomings of the past and simultaneously be inspired by ingenious inventors. The primary purpose of this review is to provide a historical perspective of clamps and forceps commonly used in orthopedic surgery, to better appreciate the evolution of their use over time, and to inspire innovation to constantly improve upon surgical instrumentation as the field of orthopedic surgery advances.
