  Objective To describe the nationwide population of anterior cruciate ligament (ACL) injured patients initially managed non-operatively, quantify the proportion undergoing delayed ACL reconstruction (ACLR) and describe both intraoperative findings and patient-reported outcomes. Methods Primary ACL injuries treated non-operatively were prospectively registered in the Norwegian Knee Ligament Register (2017–2023). We collected baseline characteristics, injury details, surgical details if delayed ACLR was performed and patient-reported outcomes (Knee injury and Osteoarthritis Outcome Score, KOOS). Treatment survival was analysed with Kaplan-Meier curves, and factors associated with ACLR were assessed with Cox regression. Results Of 485 patients included (mean age at injury (SD) 35 (12), 25%<25 years), 93% (n=452) were physically active in sports preinjury. At 2 years, 63% remained non-operatively treated. Of the delayed ACLR patients (n=178), 56% underwent concurrent meniscal repair, and 18% partial resection. Instability was the main reason for ACLR (85%). Patients younger than 25 years, those active in pivoting sports preinjury and those with meniscal injuries at baseline were more likely to undergo delayed ACLR (HR (95% CI) 1.95 (1.2 to 3.2), 1.54 (1.1 to 2.2) and 1.63 (1.2 to 2.2), respectively. Both non-operative and delayed ACLR patients showed moderate impairment on KOOS Sport/Recreation and Quality of Life subscales at 2-year follow-up (mean scores 69.8 vs 61.0 and 68.6 vs 63.4), with no statistically significant between-group differences. Conclusion In this active population of ACL injured patients treated non-operatively, two-thirds remained non-operatively treated at 2 years. Younger patients, those engaged in pivoting sports preinjury and those with baseline meniscal injuries had higher risks of undergoing delayed ACLR. KOOS scores were similar between non-operative and delayed ACLR patients.

Major Increase in Incidence of Pediatric ACL Reconstructions From 2005 to 2021: A Study From the Norwegian Knee Ligament Register. American Journal of Sports Medicine.

  Background: The incidence of pediatric and adolescent anterior cruciate ligament reconstruction (ACLR) is increasing in several countries. It is uncertain whether this trend applies to countries that traditionally prefer an initial nonoperative treatment approach whenever possible, like Norway. Nationwide, long-term patient-reported outcomes and revision rates after ACLR in the pediatric population are also lacking. Purpose: To determine the incidence of pediatric ACLR in Norway since 2005, as well as to detect trends in surgical details and describe patient-reported outcomes up to 10 years after ACLR. Study Design: Descriptive cohort study. Methods: This study is based on prospectively collected data on girls ≤14 years and boys ≤16 years, registered in the Norwegian Knee Ligament Register at the time of their primary ACLR, between 2005 and 2021. The main outcome was the incidence of ACLR, adjusted to the corresponding population numbers for each year. The time trend was analyzed by comparing the mean of the first and last 3-year period (2005-2007 and 2019-2021). Patient-reported outcomes were assessed using the Knee injury and Osteoarthritis Outcome Score preoperatively and at 2, 5, and 10 years postoperatively. Results: A total of 1476 patients (1484 cases) were included, with a mean follow-up of 8.1 years (range, 1-17). The incidence of pediatric ACLRs per 100,000 population increased from 18 to 26, which corresponds to an increase of 40% for boys and 55% for girls. Concurrent meniscal procedures increased significantly from 45% to 62%, and the proportion of meniscal repairs increased from 19% to 43% when comparing the first and last time period. The mean Knee injury and Osteoarthritis Outcome Score values for the Sport and Recreation and Quality of Life subscales were between 72 and 75 at the 2-, 5- and 10-year follow-up. The 5-year revision rate was 9.9%. Conclusion: There was a major increase in incidence of pediatric ACLR in Norway during the study period. There was a shift in the approach to concomitant meniscal procedures from resection to repair, with more than a doubling of the proportion of meniscal repairs. Patient-reported outcomes revealed long-lasting reduced knee function.

  Verletzungen des vorderen Kreuzbandes (VKB) bei Kindern und Jugendlichen sind eine bedeutsame gesundheitliche und ökonomische Belastung und ihre Inzidenz steigt schneller als die in der erwachsenen Bevölkerung. Diese Verletzung beeinträchtigt die Lebensqualität, indem sie sich auf die Entwicklung des Kniegelenkes ebenso wie auf seine zukünftige Funktionalität auswirkt und zur frühzeitigen Entwicklung einer Arthrose führen kann. Aufgrund des jungen Alters haben diese Patienten zusätzlich ein erhöhtes Risiko für sekundäre intraartikuläre Folgeschäden und erneute Verletzungen des VKB. Die geringe Anzahl kindlicher VKB-Verletzungen in einzelnen Krankenhäusern macht internationale multizentrische Studien notwendig, um aussagekräftige prospektive Daten und Langzeitergebnisse in diesem jungen Patientenkollektiv zu erfassen. Aktuell fehlt es an qualitativ hochwertigen Studien zur Behandlung einer kindlichen VKB-Ruptur und die Evidenzlage aktueller Behandlungsempfehlungen ist unzureichend. Aus diesem Grund entstand 2013 die Initiative zur Erfassung von Verletzungen des vorderen Kreuzbandes bei Kindern und Jugendlichen (Paediatric Anterior Cruciate Ligament Monitoring Initiative, PAMI). Dieses Register dient der Sammlung und Analyse von Daten zur Diagnostik und Behandlung von VKB-Verletzungen im Kindes- und Jugendalter und soll eine Grundlage für die Erstellung internationaler evidenzbasierter Leitlinien liefern. Seit 2018 werden für das PAMI-Register Patienten mit einem Skelettalter von 8-14 Jahren bei Mädchen beziehungsweise 8-16 Jahren bei Jungen in verschiedenen internationalen Zentren erfasst, wobei die Zahl der Rekrutierungszentren ebenso wie die Patientenzahl stetig ansteigen. Die Auswertung der Angaben aus den ersten drei Jahren des Projektes liefert bereits aussagekräftige epidemiologische Daten und erste Trends. Es zeigt sich, dass das Projekt international gut anerkannt wurde. Eine zukünftige Herausforderung liegt in der langfristigen Etablierung der PAMI und die Verbreitung der wissenschaftlichen Erkenntnisse.

Change in Posterior Tibial Slope in Skeletally Immature Patients With Anterior Cruciate Ligament Injury: A Case Series With a Mean 9 Years’ Follow-up. American Journal of Sports Medicine.

  Background: Increased lateral posterior tibial slope (LPTS) is associated with increased rates of anterior cruciate ligament (ACL) injury and failure of ACL reconstruction. It is unknown if ACL deficiency influences the developing proximal tibial physis and slope in skeletally immature patients through anterior tibial subluxation and abnormal force transmission. Purpose: To assess the natural history of LPTS in skeletally immature patients with an ACL-injured knee. Study Design: Case series; Level of evidence, 4. Methods: A total of 38 participants from a previous study on nonoperative management of ACL injury in skeletally immature patients were included. During the initial study, bilateral knee magnetic resonance imaging (MRI) was performed within 1 year of enrollment and again at final follow-up. All patients were younger than 13 years at the time of enrollment, and final follow-up occurred a mean 10 years after the injury. MRI scans were retrospectively reviewed by 2 reviewers to determine bilateral LPTS for each patient and each time point. Linear mixed models were used to assess LPTS differences between knees, change over time, and association with operational status. Subgroup analyses were performed for patients who remained nonoperated throughout the study. Results: A total of 22 patients had ACL reconstruction before final follow-up and 16 remained nonoperated. In the entire study population, the mean LPTS was higher in the injured knee than in the contralateral knee at final follow-up by 2.0° (P < .001; 95% CI, 1.3°–2.6°). The mean LPTS increased significantly in the injured knee by 0.9° (P = .042; 95% CI, 0.03°–1.7°), while the mean LPTS decreased in the contralateral knee by 0.4° (P = .363; 95% CI, –0.8° to 0.4°). A significant difference in LPTS was also observed in the nonoperated subgroup. No significant association was observed between LPTS and operational status. Conclusion: Lateral posterior tibial slope increased more in the ACL-injured knee than in the contralateral uninjured knee in a group of skeletally immature patients. Lateral posterior tibial slope at baseline was not associated with the need for surgical reconstruction over the study period.

  Paediatric and adolescent ACL injuries are an emerging health burden, increasing at a higher rate than in adults. They compromise quality of life, affect knee structure and function, lead to the early development of osteoarthritis and are a serious economic burden due to shortened professional careers and subsequent surgeries. Up to 35% of children and adolescents will experience a second ACL injury and this population particularly at high risk of secondary intraarticular soft tissue degeneration and growth abnormalities. However, there is still a lack of high-quality outcome studies on this specific population and many knowledge gaps persist in the current treatment guidelines. It is currently unknown whether ACL reconstruction in this young population decreases the risk of irreversible secondary intraarticular soft tissue degeneration. Furthermore, it is not known whether return to high or elite level sports after paediatric ACL injury or reconstruction should be recommended. The relatively low number of paediatric ACL injuries seen in each hospital makes it necessary to conduct international multi-centre studies to collect robust data to provide evidence-based guidelines for the treatment of these injuries. The Paediatric Anterior Cruciate Ligament Initiative (PAMI) was thus started by the European Society of Sports Traumatology, Knee Surgery & Arthroscopy and opened for patient inclusion in 2018. This comprehensive overview of the first 2 years of the PAMI registry shows that the project is now well consolidated and accepted by the European orthopaedic community. Future challenges include ensuring additional external funding to ascertain long term sustainability and continuous dissemination of the knowledge acquired in scientific journals.

  Objective: To investigate the risk of new meniscal tears after treatment for anterior cruciate ligament (ACL) injury, in children and adults with and without ACL reconstruction. Design: Prognosis systematic review (PROSPERO registration number CRD42016036788). Methods: We searched Embase, Ovid Medline, Cochrane, CINAHL, SPORTDiscus, PEDro and Google Scholar from inception to 3rd May 2018. Eligible articles included patients with ACL injury (diagnosis confirmed by MRI and/or diagnostic arthroscopy), reported the number of meniscal tears at the time of ACL injury diagnosis/start of treatment and reported the number of new meniscal tears that subsequently occurred. Articles with fewer than 20 patients at follow-up, and articles limited to ACL revision surgery or multi-ligament knee injuries were excluded. Two independent reviewers screened articles, assessed eligibility, assessed risk of bias and extracted data. We judged the certainty of evidence using the Grading of Recommendations Assessment Development and Evaluation (GRADE) working group methodology. Results Of 75 studies included in the systematic review, 54 studies with 9624 patients and 501 new meniscal tears were appropriate for quantitative analysis. Heterogeneity precluded data pooling. The risk of new meniscal tears was 0%–21% when follow-up was

  Background: The rate of secondary knee injuries after pediatric anterior cruciate ligament (ACL) injury is uncertain, and previous studies are limited because of poor methodology. Purpose: To evaluate the incidence of new meniscal injuries since the initial diagnostic magnetic resonance imaging (MRI) of young adults who sustained a pediatric ACL injury. In addition, to evaluate meniscal and cartilage injuries in the index knee and contralateral knee injuries on MRI at final follow-up (9.5 years). Furthermore, to assess leg length and alignment based on long-leg radiographs. Study Design: Case series; Level of evidence, 4. Methods: Study population at final follow-up included 47 young adults who sustained a pediatric ACL injury before age 13 years. They were followed prospectively since the time of injury for a mean 9.5 years at final follow-up. Imaging included diagnostic MRI of the index knee and 3.0-T MRI of both knees at 1-, 2-, and 9.5-year follow-up, in addition to long-leg radiographs at final follow-up. Forty-three patients underwent active rehabilitation without ACL reconstruction initially; 4 were treated with initial ACL reconstruction. At final follow-up, 27 (57%) had undergone ACL reconstruction. Results: Fourteen patients had meniscal tears in the index knee at final follow-up (prevalence, 30%). The majority of these were in the same location as previously repaired tears (n = 9). Between diagnostic MRI and final follow-up, 16 patients had sustained new meniscal tears to a healthy meniscus (incidence, 34%). At final follow-up, meniscal injuries recorded at baseline or during follow-up were no longer visible and appeared healed in 17 patients (20 tears). MRI at final follow-up showed cartilage injuries in the index knee of 13 patients (28%) and contralateral injuries in 8 patients (meniscus, n = 2; cartilage, n = 5; subchondral fracture, n = 1). Two patients had a leg-length difference >15 mm, and 3 had side-to-side difference in knee alignment >5°. Conclusion: The incidence of new meniscal tears after pediatric ACL injury was 34% during a mean follow-up period of 9.5 years. At final follow-up, 27 patients (57%) had normal menisci, and none had developed knee osteoarthritis. Primary active rehabilitation, close follow-up, and delayed surgery if needed may be a viable and safe treatment option for some pediatric ACL injuries.

  Background: There is no consensus regarding the best treatment approach for skeletally immature children with anterior cruciate ligament (ACL) injuries. High-quality studies with long-term follow-up are lacking, and evidence to support decision making is limited. Purpose: To evaluate functional and patient-reported outcome, surgical history, and complications among young adults who sustained an ACL injury before the age of 13 years and were treated with active rehabilitation and the option of delayed ACL reconstruction if needed. Study Design: Case series; Level of evidence, 4. Methods: Forty-six children aged <13 years with a total intrasubstance ACL injury were included. None of these patients had additional injuries that warranted early surgery. At final follow-up at a mean 8 years after the time of injury, 44 patients remained in the study. The same test battery was conducted at baseline, 1 and 2 years, and final follow-up at approximately 18 years of age. The test battery included functional tests (hop tests and isokinetic muscle strength tests of quadriceps and hamstrings), patient-reported outcome measures (including the Knee injury and Osteoarthritis Outcome Score and the International Knee Documentation Committee Subjective Knee Form), and clinical examination. Medical records were reviewed to assess surgical history and complications. Results: At a mean 8 years of follow-up, 24 patients (55%) had undergone ACL reconstruction, and 16 (36%) had undergone meniscal surgery. Quadriceps muscle strength symmetry was >90% for 30 patients (68%). Mean leg symmetry indexes for hop and strength tests were consistently >90%, except for the single-hop test and hamstrings muscle strength for ACL-reconstructed knees. Mean ± SD International Knee Documentation Committee scores were 86.3 ± 13.7 for the ACL-reconstructed knees and 90.6 ± 11.8 for the nonreconstructed knees. At final follow-up, forty patients (91%) remained active in sports, but 29 (66%) restricted their activity level to nonpivoting sports. Conclusion: Active rehabilitation may have a role in treatment of children with ACL injury. Approximately 50% of children may cope well, even to adulthood, without a surgical intervention. The other half may develop instability that warrants ACL reconstruction, and one-third may require meniscal surgery.

  In October 2017, the International Olympic Committee hosted an international expert group of physical therapists and orthopaedic surgeons who specialize in treating and researching pediatric anterior cruciate ligament (ACL) injuries. The purpose of this meeting was to provide a comprehensive, evidence-informed summary to support the clinician and help children with ACL injury and their parents/guardians make the best possible decisions. Representatives from the following societies attended: American Orthopaedic Society for Sports Medicine; European Paediatric Orthopaedic Society; European Society for Sports Traumatology, Knee Surgery, and Arthroscopy; International Society of Arthroscopy, Knee Surgery and Orthopaedic Sports Medicine; Pediatric Orthopaedic Society of North America; and Sociedad Latinoamericana de Artroscopia, Rodilla, y Deporte. Physical therapists and orthopaedic surgeons with clinical and research experience in the field and an ethics expert with substantial experience in the area of sports injuries also participated. This consensus statement addresses 6 fundamental clinical questions regarding the prevention, diagnosis, and management of pediatric ACL injuries. Injury management is challenging in the current landscape of clinical uncertainty and limited scientific knowledge. Injury management decisions also occur against the backdrop of the complexity of shared decision making with children and the potential long-term ramifications of the injury.

  Women remain underrepresented in orthopedic surgery, accounting for only 13% of surgeons in Europe despite forming the majority of physicians overall. Structural barriers, including limited mentorship and work–life challenges, continue to hinder progress. To address these issues, the European Society of Sports Traumatology, Knee Surgery and Arthroscopy (ESSKA) launched the Women in ESSKA initiative in 2018, fostering mentorship, leadership and visibility. Female membership and congress participation have since more than doubled, reflecting steady progress. Sustained equity efforts must extend beyond participation numbers to include transparent leadership pathways and fair representation in authorship and decision‐making. True progress will depend on collaboration between women and men alike, ensuring that gender equity in orthopedics strengthens, not replaces, the core value of merit‐based excellence.
