Background: There is a lack of research investigating current practice trends in the treatment of anterior cruciate ligament (ACL) tears as well as common concomitant procedures and reoperations associated with ACL reconstruction (ACLR). Purpose: To analyze current practice patterns for ACLR as well as the frequency of concomitant and revision procedures with respect to patient characteristics in a cross-sectional population of the United States. Study Design: Cross-sectional study; Level of evidence, 3. Methods: Patient data between 2010 and 2017 were queried using the Mariner PearlDiver database. International Classification of Diseases, Ninth Revision (in 2010-2014) and Tenth Revision (ICD-10; in 2015-2017), diagnosis codes were used to identify ACL tears, and Current Procedural Terminology codes were used to identify ACLR and concomitant surgical procedures. Patient characteristics were stratified by sex and age. Cases of subsequent knee surgery and conversion to total knee arthroplasty (TKA) within 2 years after ACLR were tracked using ICD-10 codes between 2015 and 2017 to ensure ipsilateral laterality. Results: Of 229,295 patients identified with an ACL tear diagnosis during the study period, 75% underwent ACLR. In patients aged 10 to 39 years, 84% to 92% underwent ACLR, while patients aged 50 to 59 (50%) and 60 to 69 (28%) years were less likely to have surgery after an ACL tear. Female and male patients underwent ACLR at a similar rate (75%). Within the patients who underwent ACLR, 44% underwent concomitant meniscal debridement as compared with 11% with concomitant meniscal repair. Male patients were more likely to undergo meniscal debridement (48% vs 40%; P < .0001). The frequency of meniscal repair increased from 9% in 2010 to 14% in 2017, while the frequency of meniscal debridement decreased from 47% to 41% ( P < .0001). Within 2 years of ACLR, 6% of patients underwent revision ACLR; 4%, subsequent meniscal debridement; 1%, meniscal repair; and 1%, conversion to TKA. Conclusion: The frequency of ACLR for ACL tears has remained relatively stable in recent years and was similar between female and male patients in this cross-sectional population. The majority of patients aged 10 to 39 years underwent ACLR, while less than half of patients >50 years underwent surgery.

Background: The coronavirus disease 2019 (COVID-19) pandemic drastically altered children’s activity patterns. Our goal was to investigate how COVID-19 affected demographics, injury characteristics, treatment patterns, follow-up, and outcomes in pediatric supracondylar humerus (SCH) fractures. Methods: This was an Institutional Review Board–approved retrospective analysis of patients undergoing surgery for a SCH fracture from May to November 2019 (pre-COVID-19) and from May to November 2020 (during COVID-19) at 2 tertiary children’s hospitals. Demographic information, injury characteristics, hospital course, and follow-up data were collected and compared. Results: SCH fractures decreased by >50% from 2019 (149) to 2020 (72). Children in the 2020 cohort were younger (mean 5.2 y old) compared with 2019 (6.0 y old) (P=0.019). Mechanism of injury was significantly different in 2020 (P<0.001), as the proportion of trampoline and furniture fractures increased from 8% and 17% to 15% and 33%, respectively. The proportion of playground and monkey bar fractures decreased from 20% and 17% to 3% and 4%, respectively. Distribution of Gartland type and neurovascular injury rates were similar in 2019 and 2020 (P=0.411 and 0.538). Time from emergency department admission to the operating room and duration of hospital admission were both unchanged from 2019 to 2020 (P=0.864 and 0.363). The duration of postoperative follow-up in 2019 was 94.5 days compared with 72.8 days in 2020 (P=0.122), as more pandemic patients were lost to follow up (22.5% vs. 35.2%, P=0.049). Conclusions: The demographics, mechanism of injury, and follow-up practices of pediatric SCH fractures changed significantly during the pandemic, likely because of school closures and lock-downs changing activity patterns. Different mechanisms of injury affected younger patients and reflected the new ways children played. Trampoline-related and furniture-related injuries overtook the classic playground falls as primary mechanism of injury. Despite the need for COVID-19 testing, there was no delay in time to the operating room. Hospitalization duration did not change, yet postoperative follow-up was shorter, and more patients were lost to follow up. Despite these stressors, outcomes remained excellent in most children. Level of Evidence: Level III—Retrospective comparative study.
