Introduction: Anterior cruciate ligament (ACL) injuries may be managed nonoperatively in certain patients and injury patterns; however, complete ACL ruptures are commonly reconstructed to restore anterior and lateral rotatory stability of the knee. While ACL reconstruction is well-studied, the literature is sparse with regard to which socioeconomic patient factors are associated with patients undergoing ACL reconstruction rather than nonoperative management after diagnosis of an ACL injury. The current study seeks to evaluate this relationship between patient demographics as well as socioeconomic factors and the rate of surgery following ACL injuries. Methods: Patients ≤65 years of age with a primary ACL injury between 2011 and 2018 were retrospectively identified in the New York Statewide Planning and Research Cooperative System database. International Classification of Disease 9/10 and Current Procedural Terminology codes were used to identify these patients and their subsequent ACL reconstructions. Logistic regression was performed to determine the effect of patient factors on the likelihood of having surgery after the diagnosis of an ACL injury. Results: Compared to White patients, African American patients were significantly less likely to undergo ACL reconstruction following an ACL injury (OR=0.65, 95% CI, 0.573–0.726). Patients older than 35 had decreased odds of undergoing ACL reconstruction compared to younger patients, with patients 55–64 having the lowest odds (OR=0.166, 95% CI, 0.136–0.203). Patients with Medicaid (OR=0.84, 95% CI, 0.757–0.933) or self-pay insurance (OR=0.67, 95% CI, 0.565–0.793), and those with worker’s compensation (OR=0.715, 95% CI, 0.621–0.823) had decreased odds of undergoing ACL reconstruction relative to patients with private insurance. Patients with higher Social Deprivation Index (SDI) were significantly more likely to be treated nonoperatively after ACL injuries compared to those with lower SDI (mean nonoperative SDI score, 61, operative SDI, 56, P<0.0001). Discussion: In patients with ACL injuries, there are socioeconomic and patient-related factors that are associated with increased odds of undergoing ACL reconstruction. These factors are important to recognize as they represent a source of potential inequality in access to care and an area with potential for improvement.

Tibial spine fractures are a relatively rare injury in the young athlete. Previously thought to be the equivalent of a “pediatric anterior cruciate ligament (ACL) tear,” contemporary understanding of these injuries classifies them as distinct from ACL injuries in this patient population. Successful treatment hinges on accurate diagnosis paying special attention to fracture displacement and the presence of concomitant intraarticular injury. Surgery can be performed using open or arthroscopic techniques and a variety of fixation options. The most common complication after surgical treatment is arthrofibrosis and, therefore, stable fixation is necessary to allow for early, unimpeded knee motion postoperatively.

Osteogenesis imperfecta is caused by qualitative or quantitative defects in type I collagen. Although often considered a disease with primarily pediatric manifestations, more than 25% of lifetime fractures are reported to occur in adulthood. General care of adults with osteogenesis imperfecta involves measures to preserve bone density, regular monitoring of hearing and dentition, and maintenance of muscle strength through physical therapy. Surgical stabilization of fractures in these patients can be challenging because of low bone mineral density, preexisting skeletal deformities, or obstruction by instrumentation from previous surgeries. Additionally, unique perioperative considerations exist when operatively managing fractures in patients with osteogenesis imperfecta. To date, there is little high-quality literature to help guide the optimal treatment of fractures in adult patients with osteogenesis imperfecta.

Osteochondritis dissecans (OCD) can cause knee pain and dysfunction in children. The etiology of OCD remains unclear; theories on causes include inflammation, ischemia, ossification abnormalities, genetic factors, and repetitive microtrauma. Most OCD lesions in skeletally immature patients will heal with nonoperative treatment. The success of nonoperative treatment decreases once patients reach skeletal maturity. The goals of surgical treatment include maintenance of articular cartilage congruity, rigid fixation of unstable fragments, and repair of osteochondral defects with cells or tissues that can adequately replace lost or deficient cartilage. Unsalvageable OCD lesions can be treated with various surgical techniques.

Pathologic fractures through benign bone lesions in children and adolescents should be approached in a systematic fashion in order to ensure appropriate management. The etiology, natural history, and treatment of the underlying abnormality must be taken into account when treating these fractures because the treatment of the fracture will often be altered by the presence of the lesion and vice versa. Most pathologic fractures through benign lesions can be treated closed; however, there are certain circumstances in which open treatment is advisable. A thorough and thoughtful evaluation of the patient who presents with a pathologic fracture through a benign lesion will help lead to an optimal outcome.

Objective To examine the incidence and risk factors of any-cause reoperation after primary ACLR in children and adolescents.Design Retrospective CohortSetting Electronic medical records from a large tertiary care, single institution integrated healthcare delivery system.Patients Patients were under the age of 18 years and had anterior cruciate ligament reconstruction. They were excluded if they had a multi-ligamentous knee injury or <1 year follow-up.Interventions Patients were further identified to have undergone a subsequent knee operation ipsilaterally or contralateral ACLR.Main outcome measures The rate of any-cause reoperation was our primary outcome measure.Results The median age was 16. There were 208 females (53.9%) and 178 males (46.1%) included. The median follow-up was 25 months with a minimum of 12 months (interquartile range: 16.0, 46.0). The rate of any-cause reoperation was 34.7%. There was no statistically significant difference between those who underwent reoperation versus those who did not undergo reoperation relative to age, sex, BMI, graft type, or the presence of concomitant meniscal injury. The rates of ipsilateral ACLR and contralateral ACLR at any time during the study period was 8.0% and 10.9% respectively. There was no statistically significant difference for rate of reoperation between graft types, between various concomitant injuries, between those who underwent meniscus repair or no repair.Conclusions This study reflects a 34.7% rate of a subsequent knee operation after ACLR in patients younger than 18 years. These findings can be used to inform pediatric patients undergoing primary ACLR on their risk of returning to the operating room.
