    Abstract Aim: Arthrodesis of the shoulder joint is a radical event, so it is difficult to explain its significance to patients. It has been the last resort in hopeless cases. Knowledge of long-term results and evaluation of advantages and disadvantages seems to be helpful in this regard.
    Methods: Eleven patients with mean age of 45 (31 - 58) years were operated between 2000 and 2013. All patients could be included in the investigation (FU mean 8.5 [3 - 16] years; 8 male and 3 female; right 9, left 2). Patients had the following indications: persistent instability 5 (2 with epilepsy), rotator cuff rupture 2 (1× after combined latissimus dorsi and teres major transfer), brachial plexus injury/defect 2, locked dislocation 1 and posttraumatic arthropathy 1. Fixation with DC plate (pre-bent to 110°) was used in all cases; with special focus on placing at least one screw in the scapular neck. The targeted arthrodesis position was abduction 30°, forward flexion 30°, and internal rotation 30°.
    Results: Active abduction improved from 12 to 63°, forward flexion from 21 to 79° and internal rotation from 10 to 47° (mean values). In the resting position with hanging arm aside, mean abduction was 3° and forward flexion 8°. Nine of 11 patients had considerable relief of pain, from 8.3 to 2.4 points VAS. Five patients rated the outcome as excellent, 3 as good and 1 as satisfactory. Nine patients would repeat the procedure. In summary, an Oxford Shoulder Score of 31.6 points was achieved, and SSV of 58%. Bony fusion was achieved in all cases, 3 - 4 months p. o. in mean. There were no important neurological or angiological complications.
    Conclusions: Plate arthrodesis in the technique used achieves high fusion and a low complication rate. Relief of pain and functional improvement are astonishing. Analysis of our results indicates that correction of the positions mentioned above is necessary: i. o. arthrodesis position for abduction 25° (by means of pre-bending plate of 105°), forward flexion 20° and internal rotation 30° are suggested.

    Abstract Purpose: Effusion, impaired muscle function and knee instability are considered as some of the most important factors effecting outcome following anterior cruciate ligament reconstruction (ACL-R) but the impact on revision ACL-R remains unclear. It was hypothesized that these factors will significantly worsen clinical outcome following revision ACL-R.
    Methods: Seventy knees (13 female and 57 male) were followed retrospectively after revision ACL-R at a mean follow-up of 47.8 ± 20.7 months. Clinical examination was based on the International Knee Documentation Evaluation Form-2000 (IKDC), Tegner activity scale. Instrumented measurement of anterior tibial translation was performed using the Rolimeter® (DJO Global, Freiburg, Germany). Bilateral circumference of the thigh was measured 10 and 20 cm proximal to the medial joint space. Cartilage was assessed according to Outerbridge classification during both primary and revision ACL-R.
    Results: Tegner activity scale decreased significantly from 7.8 ± 1.4 points at primary ACL-R to 7 ± 1.8 points at revision ACL-R, and 5.8 ± 1.7 points at the time of follow up (p < 0.001). Joint effusion (r = - 0.47, p < 0.01) and side to side differences in single leg hop test (r = - 0.48, p < 0.1) significantly correlated with inferior outcome. Cartilage lesions were found in 67% of the patients at the time of revision ACL-R compared to 38% at the time of primary ACL-R. According to the IKDC classification A was graded in three patients (4.3%), B in 35 (50%), C in 29 (41.4%) and D in three (4.3%). Joint effusion was measured in 35% of patients at the time of follow-up. Degeneration at the patellofemoral compartment of > grad 2 was responsible for IKDC grade C and D (p = 0.035). Instrumented anteroposterior site-to-site difference of ≥3 mm showed significant impact on clinical outcome (p < 0.019).
    Conclusion: The study has shown that chronic effusion, quadriceps dysfunction, cartilage lesions especially at the patellofemoral compartment and side to side difference in anteroposterior stability significantly influences patient outcome after revision ACL-R. These factors require special attention when predicting patient's outcome.
    Level of evidence: Level-IV, case-controlled study.

    Abstract Purpose: Degeneration of the cartilage after anterior cruciate ligament reconstruction (ACL-R) is known, and further deterioration can be expected in patients with tunnel malplacement or partial meniscal resection. It was hypothesized that there is a significant increase in cartilage degeneration after failed ACL-R.
    Material and methods: Isolated ACL revision surgery was performed in 154 patients at an interval of 46 ± 33 months (5-175 months) between primary and revision surgery. Cartilage status at the medial, lateral femorotibial, and patellofemoral compartments were assessed arthroscopically during primary and revision ACL-R in accordance with the Outerbridge classification. Tunnel placement, roof angle, and tibial slope was measured using anteroposterior and lateral radiographic views.
    Results: Cartilage degeneration increased significantly in the medial femorotibial compartment, followed by the lateral and patellofemoral compartments. There was a correlation between both cartilage degeneration in the patellofemoral compartment (PFC) (r
    Discussion: Accelerated cartilage degeneration and high prevalence of meniscal lesions are seen in failed ACL-R. Tunnel placement showed significant impact on cartilage degeneration and may partially explain the increased risk of an inferior outcome when revision surgery is required after failed primary ACL-R.
    Level of evidence: Level IV-retrospective cohort study.

Gelegentlich stellt dieses Verfahren aber in problematischen Fällen die letzte Möglichkeit dar. Das Wissen um die Langzeitergebnisse kann deshalb bei der Erläuterung der Vor- und Nachteile dieser Methode dem Patienten gegenüber von erheblichem Nutzen sein.
    Methodik: Im Zeitraum von November 2000 bis August 2013 wurden 11 Patienten mit einer Schulterarthrodese versorgt, die bei einer mittleren Nachuntersuchungszeit von 8,5 (3 – 16) Jahren alle nachuntersucht werden konnten (8 Männer, 3 Frauen; rechts 9-mal, links 2-mal, Durchschnittsalter 45 [31 – 58] Jahre). Die Indikation zu dem Eingriff wurde 5-mal wegen einer nicht beherrschbaren und mehrfach voroperierten Instabilität gestellt (davon 2-mal bei Epilepsie), 2-mal wegen einer Rotatorenmanschettendefektarthropathie (davon einmal bei Z. n. kombiniertem Latissimus-dorsi- und Teres-major-Transfer), 2-mal wegen einer oberen Plexusläsion, einmal wegen einer persistierenden Luxation und einmal wegen einer posttraumatischen Defektarthropathie. Alle OPs erfolgten mittels der AO-Technik (8-mal Zweischnittzugang, 3-mal Einschnittzugang), d. h. Fixation mittels einer schmalen DC-Platte, die im Mittel auf 110° vorgebogen wurde. Besonderer Wert wurde bei der Fixation auf die Platzierung einer, besser von 2 von kranial durch die Platte geführten Schrauben im Skapulahals gelegt. Intraoperativ wurde eine Armposition von Abduktion/Anteversion/Innenrotation 30/30/20 angestrebt.
    Ergebnisse: Durch den Eingriff wurde eine deutliche Verbesserung der aktiven Beweglichkeit erreicht, von 12 auf 63° für die Abduktion, von 21 auf 79° für die Anteversion und von 10 auf 47° für die Innenrotation (Mittelwerte). In Ruheposition hing der Arm locker entspannt mit 3° Abduktion und 8° Anteversion am Körper herab. Neun der 11 Patienten waren zufrieden bzw. sehr zufrieden und würden den Eingriff wiederholen lassen. Die Schmerzlinderung verbesserte sich auf der VAS von 8,3 auf 2,4 Punkte. Im Oxford Shoulder Score wurden 31,6 Punkte erreicht und im Simple Shoulder Value 58%. Röntgenologisch waren alle Arthrodesen nach 3 – 4 Monaten knöchern durchgebaut. An Komplikationen ist eine Fehlstellung mit postoperativer subkapitaler Korrekturosteotomie zu nennen. Relevante neurologische oder Gefäßkomplikationen traten nicht auf.
    Schlussfolgerungen: Es handelt sich bei der beschriebenen Technik um eine sichere und reproduzierbare OP-Technik mit hoher Ausheilungs- und erstaunlich geringer Komplikationsrate. Schmerzlinderung und Funktionsverbesserung sind enorm, wobei die Zufriedenheit der Patienten von der Ausgangslage abhängt – die Patienten mit den präoperativ stärksten Schmerzen waren am zufriedensten. In Auswertung unserer Ergebnisse ist eine Korrektur der o. g. Empfehlungen für die Arthrodesenposition erforderlich: Abduktion 25° (mittels der auf 105° vorgebogenen Platte), Anteversion von 20° und Innenrotation von 30°.
