Summary
In a previous investigation of 41 patients presenting with distended popliteal cysts, a valvular mechanism was demonstrated in 25 cases by means of a specific arthrographic procedure. In the present study the clinical symptoms and signs from the popliteal space and from the joint were assessed and related to the presence or absence of a valvular mechanism. By arthroscopy or arthrotomy seventeen associated knee disorders were diagnosed, e.g., synovitis, osteoarthritis, and tears of a semilunar cartilage. Intra-articular symptoms and intrinsic joint diseases were significantly correlated to the absence of a valve mechanism. The presence of a valve mechanism was indicative of the absence of pathological findings in the joint.
Zusammenfassung
In einer vorhergegangenen arthrographischen Studie war bei 25 von 41 Patienten mit klinisch nachgewiesenen Kniekehlenzysten ein Ventilmechanismus zwischen der Zyste unter der Gelenkhöhle nachgewiesen wurden. In der vorliegenden Studie werden die Symptome und Befunde vom Gelenk untersucht und zu dem Vorhandensein eines Ventilmechanismus in Beziehung gesetzt. Mittels Arthro-skopie und/oder Arthrotomie wurden 17 zugeordnete Gelenkerkrankungen diagnostiziert, u. a. Synovitis, Arthrose und Meniskusschäden. Beim Fehlen eines Ventilmechanismus wurden in der Regel pathologische intraartikuläre Befunde erhoben, während nur ausnahmsweise Gelenkbeschwerden und -erkrankungen nachgewiesen wurden, wenn ein Ventilmechanismus den Rückfluß des Zysteninhaltes in das Gelenk verlegte.
