Rotationsinstabilitäten könnten neben einer Rekonstruktion des vorderen Kreuzbandes (VKBR) eine zusätzliche Versorgung der anterolateralen Kniestrukturen erfordern. Eine vermeintliche Entlastung und damit verbunden Protektion des VKBR-Transplantates durch eine anterolaterale Tenodese (ALT) wurde bisher unzureichend untersucht. Ziel der Studie war die direkte Messung der Kräfte im VKBR und ALT Transplantat inklusive der Analyse der resultierenden tibiofemoralen Relativbewegung bei anterolateraler Insuffizienz in ausgewählten Beugestellungen. Es sollte untersucht werden, ob eine zusätzliche ALT die auftretenden Kräfte im VKBR Transplantat bei externen Lasten reduziert und etwaige Rotationsinstabilitäten nach isolierter VKBR minimiert. Sechs Humanpräparate wurden in 0°, 30°, 60° und 90° Flexion in folgenden Zuständen mit Hilfe eines Kniesimulators untersucht: 1) nativ; 2) VKB durchtrennt 3) mit zusätzlicher anterolateraler Insuffizienz; 4) isolierte VKBR; 5) kombinierte VKBR+ALT. Die ALT wurde in modifizierte Lemaire Technik durchgeführt und in 60° Flexion mit einer Vorkraft von 20 N fixiert. VKBR und ALT Transplantatkräfte sowie die tibiofemorale Relativbewegung wurden jeweils unter verschiedenen externen Lasten analysiert: a) unbelastet; b) unter anteriorer Zugkraft von 98 N; c) unter einem tibialen Innenrotationsmoment von 5 Nm; d) unter kombiniertem tibialen Innenrotationsmoment von 5 Nm und anteriorer Zugkraft von 98 N. Bei Einleitung eines tibialen Innenrotationsmoments wurden die VKBR-Transplantatkräfte durch eine zusätzliche ALT um bis zu 58% reduziert. Die ALT nahm dabei Kräfte von bis zu 112 N auf. Unter anteriorer Zugkraft war die Wirkung der zusätzlichen ALT auf die VKBR-Transplantatkräfte zu vernachlässigen. Die isolierte VKBR war nicht in der Lage, bei anterolateraler Insuffizienz den nativen Zustand tibialer Innenrotation widerherzustellen. Mittels kombinierter VKBR+ALT konnte dieser erreicht werden. In 30° Flexion zeigte sich eine unphysiologische Reduktion der tibialen Innenrotation nach kombinierter VKBR+ALT. Das VKBR Transplantat wird bei tibialen Innenrotationsbelastungen durch eine ALT entlastet. Dadurch könnte das Risiko einer Ruptur des VKBR-Transplantates bei pivotierenden Belastungen gesenkt werden. Persistente Rotationsinstabilitäten nach isolierter VKBR in anterolateral insuffizienten Kniegelenken können durch eine zusätzliche ALT reduziert werden. Eine Bewegungseinschränkung mit unphysiologisch reduzierter Innenrotation aufgrund zu hoher Spannung der ALT ist dabei nicht auszuschließen und sollte bei der Versorgung berücksichtigt werden. Rotational instability ten could be in addition to a reconstruction of the anterior cruciate ligament (VKBR) an additional supply the anterolateral knee structures require. A supposed relief and associated protection of the VKBR transplant an anterolateral tenodesis (ALT) has so far been insufficiently investigated. The aim of the study was direct Measuring the forces in the VKBR and ALT Transplant including analysis the resulting tibiofemoral Relative movement in anterolateral Insufficiency in selected flexion positions. It should be investigated whether an additional ALT is required forces occurring in the VKBR transplant reduced under external loads and any rotational instabilities minimized after isolated VKBR. Six human preparations were in 0, 30, 60 and 90 Inflection in the following states Investigated with the help of a knee simulator: 1) native; 2) ACL severed 3) with additional anterolateral Insufficiency; 4) isolated VKBR; 5) combined VKBR+ALT. The OLD was modified in Lemaire technique performed and in 60 flexion fixed with a pre-force of 20 N. VKBR and ALT transplant forces as well as the tibiofemoral relative movement were each under different external loads analyzed: a) unencumbered; b) under anterior traction from 98 N; c) under a tibial internal rotation torque of 5 Nm; d) under combined tibial internal rotation moment of 5 Nm and anterior traction force of 98 N. When initiating a tibial internal rotation moment became the VKBR transplant forces by an additional ALT by up to 58% reduced. The ALT absorbed forces of up to 112 N. Under anterior traction was the effect the additional ALT to the VKBR Graft forces can be neglected. The isolated VKBR was not in the situation with anterolateral insufficiency the native state of tibial To restore internal rotation. Means combined VKBR+ALT could this can be achieved. In 30 inflection showed an unphysiological one Reduction of tibial internal rotation after combined VKBR+ALT. The VKBR Graft is used for tibial internal rotation loads by an ALT relieved. This could reduce the risk a rupture of the VKBR transplant reduced in the case of pivoting loads become. Persistent rotational instability after isolated VKBR in anterolaterally insufficient knee joints can be replaced by an additional ALT can be reduced. A movement restriction with unphysiological reduced internal rotation due to excessive voltage on the ALT cannot be ruled out and should be taken into account when providing care become.

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. Anterior cruciate ligament (ACL) injuries in children and adolescents are a relevant health and economic burden and their incidence increases at a higher rate than in adults. These injuries compromise the quality of life, affect the development of the knee joint as well as its future functionality, and may lead to early onset of osteoarthritis. Because of their young age, these patients are furthermore at high risk for secondary intraarticular soft tissue damage and re-injury of the ACL. The relatively small number of pediatric ACL injuries in single hospitals, necessitates international multicenter studies to collect meaningful prospective data and long-term outcomes in a young patient population. As a result, there are few high-quality studies on the treatment of pediatric ACL rupture, and the evidence base of current treatment recommendations is insufficient. Thus, the Paediatric Anterior Cruciate Ligament Monitoring Initiative (PAMI) was created in 2013. The registry is designed to collect and analyze data on the diagnosis and treatment of ACL injuries in children and adolescents and to provide a basis for the development of international evidence-based guidelines. Since 2018, patients with a skeletal age of 8-14 years in girls and 8-16 years in boys, respectively, have been recruited for the PAMI registry in various international centers, and the number of recruiting centers as well as the number of patients is increasing constantly. Analysis of the data from the first three years of the project provides epidemiological data and suggests initial trends. It is evident that the project is well established and in international demand. A future challenge is to ensure the long-term durability of PAMI and the dissemination of scientific findings.

The present article describes the possibilities of synovial embolisation in the management of knee osteoarthritis. We present the etiology of knee osteoarthritis as well as the guideline orientated treatment. Many patients have comorbidities and comedications which does not allow the use of NSAR. Especially in this patient group the embolization seems to be a good option. [ABSTRACT FROM AUTHOR]

Introduction: Rupture of the anterior cruciate ligament (ACL) has been surgically reconstructed mainly arthroscopically for many years. The long-propagated single bundle replacement was followed by recommendations for the anatomical double-bundle reconstruction. The aim of this study is the evaluation of clinical follow-up results in terms of function and stability after performing an ACL reconstruction with both the single bundle (SB) and the double bundle (DB) technique. Methodology: Eighty patients receiving ACL reconstruction were included (41 SB / 39 DB). The follow-up period was 17.4 months. To assess knee joint stability, anteroposterior translation and rotation translation were determined. In addition, arthrometric measurement and the implementation of standardized scores were performed. Data were statistically evaluated using the Pearson χ2 test and Fisher's exact test (p = 0.05). Results: While the Lachman test in the SB group showed a significant (p = 0.032) greater stability of the knee joints, a higher stability of the knee joints in the DB group was documented by the anterior drawer test and the stability measurement with the rolimeter. In the DB group a significantly higher number of patients with local sensitivity deficits (p = 0.045) and paresthesia as well as a significantly higher active and passive flexion deficit were noted compared to the SB group (p = 0.09 / p = 0.038, respectively). Conclusion: Based on the results of this study it is currently not possible to give any recommendations regarding any operating procedure after a follow-up period of at least 12 months. However, there is evidence of a higher complication rate in the DB group. Clinically, these results should be considered in the evaluation of the indications. [ABSTRACT FROM AUTHOR]

Die Verwendung von Allografts in der vorderen Kreuzband (VKB)-Chirurgie erlangt immer mehr an Bedeutung. Die eingeschränkte Verfügbarkeit stellt immer weniger ein Problem dar, allerdings spielen höhere Kosten gegenüber Autografts eine Rolle. Die Sorgen vor möglichen Krankheitsübertragungen scheinen aufgrund neuer Prozessierungsverfahren in der Allograftherstellung unbegründet zu sein. Im Vergleich zu Autografts zeigen Allografts bei entsprechender Patientenselektion gleich gute Langzeitergebnisse. Im Speziellen in der Revisionssituation nach VKB-Re-ruptur sind Allografts mit Knochenblock von Vorteil, da sie ein einseitiges Vorgehen ermöglichen. Langzeitergebnisse randomisierter Studien mit entsprechender Patientenselektion bleiben noch abzuwarten, um den Stellenwert von Allografts in der VKB-Chirurgie korrekt abschätzen zu können. The use of allografts in anterior cruciate ligament (ACL) surgery is becoming increasingly frequent. The limited availability is less and less a problem, but higher costs compared to autografts play a role. Concerns about possible disease transmission seem to be unfounded due to new processing procedures in allograft manufacturing. In comparison to autografts, allografts show with appropriate patient selection equally good long-term results. Especially in the revision cases after ACL re-rupture, allografts with bone block are advantageous because they allow a one-stage procedure. Long-term results of randomized studies with appropriate patient selection remain to be seen in order to correctly assess the importance of allografts in ACL surgery. [ABSTRACT FROM AUTHOR]

Die Osteochondrosis dissecans des Kniegelenkes ist eine Erkrankung, die auf Grund einer Durchblutungsstörung unklarer Ursache bei körperlich aktiven Kindern und Jugendlichen gehäuft auftritt. Die Behandlung richtet sich nach dem stadienabhängigen Verlauf (Stadium I und II überwiegend konservativ, Stadium II und IV operativ). Die Sportfähigkeit ist nach Diagnosestellung häufig für ca. 1 Jahr nicht gegeben. Osteochondritis dissecans of the knee in consequence of disturbed blood flow in the bone appears more often in children with high physical activity. Treatment is recommended according to the stage of disease (grade I and II predominantly conservative, grade III and IV operative). Physical capacity is commonly reduced for one year.
