Technology-Assisted Hip and Knee Arthroplasty in Orthopaedic Residency Training: A National Survey.

INTRODUCTION: The adoption of technology-assisted total joint arthroplasty (TA-TJA) is increasing; however, the extent to which TA-TJA is used among orthopaedic trainees is unknown. The purpose of this study was to assess the current use of TA total knee arthroplasty (TKA) and total hip arthroplasty (THA) by orthopaedic residents and to evaluate resident perceptions toward TA-TJA in their surgical training. METHODS: In this cross-sectional study, an anonymous electronic survey was sent to all Accreditation Council for Graduate Medical Education-accredited orthopaedic surgery residency program coordinators to distribute to their PGY-2 to PGY-5 residents. The survey consisted of 24 questions, including resident demographics, utilization of TA-TJA in their training, and perceptions regarding TA-TJA. RESULTS: A total of 103 orthopaedic residents completed the survey, of whom 68.0% reported using TA-TJA at their institution. Of the residents using TA-TJA, 28.6% used TA for total TKA only, 71.4% used TA for both TKA and THA, and none used TA solely for THA. One-third of residents (33.3%) use TA for more than half of all TKAs conducted, whereas 57.0% use TA for <10% of all THAs conducted. Approximately half of all residents (49.5%) thought that training in TA-TJA should be required during residency, with no significant differences between junior and senior level residents ( P = 0.24). Most (82.0%) thought that trainees should be required to learn conventional TJA before learning TA-TJA. 63.0% thought that technology had a positive effect on their primary TJA training experience; however, 26.0% reported concern that their training conducting conventional TJA may be inadequate. DISCUSSION: This study demonstrates that most orthopaedic residents currently conduct TA-TJA and highlights notable differences in TJA training experiences. These results provide a platform for future work aimed at further optimizing TJA training in residency, particularly as technology continues to rapidly evolve and utilization of TA-TJA is projected to grow exponentially. LEVEL OF EVIDENCE: N/A, survey-based study.

Pediatric Supracondylar Humerus Fractures Can Be Safely Treated by Orthopaedic Surgeons With and Without Pediatric Fellowship Training.

BACKGROUND: The purpose of this study was to compare the outcomes of pediatric patients who were surgically treated for a supracondylar humerus fracture by pediatric fellowship-trained orthopaedic surgeons (PFT) to the outcomes of those surgically treated by orthopaedic surgeons without pediatric fellowship training (NPFT). We hypothesized that there would be no differences in patient outcomes. METHODS: A retrospective review of pediatric patients who underwent surgical treatment for a supracondylar humerus fracture with closed reduction and percutaneous pinning (CRPP) or open reduction and percutaneous pinning (ORPP) at a regional level 1 trauma center over a 5-year period was performed. Exclusion criteria were inadequate follow up or absence of postoperative radiographs. RESULTS: A total of 201 patients met the inclusion criteria. Pediatric-fellowship trained orthopaedic surgeons treated 15.9% of patients. There was no statistically significant difference in carrying angle, Baumann's angle, or lateral rotation percentage at final follow up between PFT and NPFT groups. There was no permanent neurovascular compromise in either group. Patients treated by NPFT were more likely to return to the operating room for pin removal. CONCLUSION: In this study, there was no difference in radiographic outcomes for patients with supracondylar humerus fractures surgically treated by either group. This suggests that pediatric supracondylar humerus fractures may be appropriately treated in communities without a pediatric-fellowship trained orthopaedic surgeon without compromised outcomes.Level of Evidence: III.

Assessing the Impact of the Pediatric Orthopaedic Society of North America (POSNA) Visiting Scholar Program.

BACKGROUND: The primary objective of the Pediatric Orthopaedic Society of North America (POSNA)-Children's Orthopaedics in Underserved Regions (COUR) Visiting Scholar Program is to engage emerging leaders from low-income and middle-income countries (LMICs) in POSNA educational offerings. This study aims to outline the educational and leadership activities pursued by the alumni of the POSNA-COUR Visiting Scholars Program. We hypothesized that there may be a discrepancy between visiting scholar interest level and actual participation in key follow-up educational and leadership activities. METHODS: A 32-question online survey developed by the POSNA-COUR committee was electronically delivered to the POSNA-COUR visiting scholarship recipients from 2007 to 2019. The survey inquired about scholars' educational background, clinical practice, and academic interests. Respondents also reported educational, research, and leadership activities that occurred following program participation. RESULTS: Fifty-seven percent (44/77) of the previous scholars participated in the survey. Sixty-eight percent reported that >75% of their practice was comprised of pediatric patients. The COUR scholarship afforded 15 scholars the opportunity to attend their first educational conference in North America. The majority (86%) of respondents consulted POSNA members on care-related issues, 52% organized a POSNA member's visit to their country, and 13% have become members of POSNA. Scholars shared their knowledge with colleagues through lectures (73%), demonstration of surgical skills (63%), mentorship (59%), hosting local courses (43%), and research (14%). There was a significant discrepancy between interest and actual participation in research (98% vs. 16%, P<0.0001), hosting a regional course (98% vs. 43%, P<0.0001), and becoming a member of POSNA (96% vs. 13%, P<0.0001). CONCLUSIONS: The POSNA-COUR Visiting Scholar Program is effective at providing beneficial educational opportunities to orthopaedic surgeons from LMICs. There is, however, a significant discrepancy between reported scholar interest and actual engagement in leadership endeavors including: research, organization of regional courses, and POSNA membership. The impact of the POSNA-COUR visiting scholar program can be enhanced through collaboration with scholarship alumni in these key areas. LEVEL OF EVIDENCE: Level IV-case series.

Guided Growth with Hemiplateau Elevation as an Alternative to Epiphysiodesis for Treatment of a Young Patient with Advanced Infantile Blount Disease: A Case Report.

CASE: Infantile Blount disease results from deceleration of growth by the proximal posteromedial tibial physis causing tibia vara. In advanced disease stages, surgical treatment is indicated. Owing to the young age and advanced Langenskiöld stage in this patient, a novel technique was performed combining lateral proximal physeal tethering with medial hemiplateau elevation osteotomy to correct the articular surface and unload the medial proximal tibial physis. CONCLUSION: Together, these procedures allow for correction of alignment while preserving growth potential. This technique was successful in correcting tibia vara due to infantile Blount disease while allowing continued growth in a 5-year-old patient.

Juvenile Idiopathic Arthritis for the Pediatric Orthopedic Surgeon.

Juvenile idiopathic arthritis includes conditions characterized by joint inflammation of unknown etiology lasting longer than 6 weeks in patients younger than 16 years. Diagnosis and medical management are complex and best coordinated by a pediatric rheumatologist. The mainstay of therapy is anti-inflammatory and biologic medications to control pain and joint inflammation. Orthopedic surgical treatment may be indicated for deformity, limb length inequality, or end-stage arthritis. Evaluation of the cervical spine and appropriate medication management in consultation with a patient's rheumatologist are essential in perioperative care. Preoperative planning should take into account patient deformity, contracture, small size, osteopenia, and medical comorbidities.

Arthroscopic posterior cruciate ligament reconstruction in a skeletally immature patient: a new technique with case report.

Pediatric intrasubstance posterior cruciate ligament (PCL) injuries are rare but present a significant treatment challenge. Untreated instability may lead to further knee injury, including meniscal or chondral damage. Surgical intervention risks damage to the physis, growth arrest, and angular deformity. We present the case of a skeletally immature 11-year-old boy with a high-grade intrasubstance PCL injury reconstructed using an all-arthroscopic tibial inlay technique modified to minimize risk of physeal injury. The femoral tunnels were placed entirely within the epiphysis, and the tibial physis was minimally crossed with a small drill hole and suture material. At 17 months' follow up, the patient had returned to full activity, including sports. He had a grade 1 posterior drawer and no posterior sag. Radiographs showed no degenerative changes. Both the proximal tibial and distal femoral physes were widely patent with no angular deformity. The patient had a 1-cm leg length discrepancy, with the operative limb being longer. This technical note with a case report describes a novel physeal-sparing reconstruction of the PCL in a pediatric patient with open physes.
