Summary

Fifty-three consecutive patients were treated for a symptomatic plica mediopatellaris of the knee joint with arthroscopic resection of the plica. Forty-six patients were followed up 43 months after the operation. Preoperatively, 40% of the patients had anterior knee pain on exertion, and 60% had mechanical symptoms. The symptoms were preceded by a knee trauma in 50% of the patients. The overall results after arthroscopic resection were satisfying, with 80% excellent or good results according to the Lysholm score, and 59% of the patients were completely free of symptoms. The presence of chondromalacia of the patella or femoral condyles or malalignment of the patella did not worsen the results. It is concluded that arthroscopic resection of a pathological plica mediopatellaris generally gives good results, even if other pathology of the knee joint is present.

Zusammenfassung

Vom 1.1.1980 bis 31.12. 1983 wurden 53 Patienten mit symptomatischer Plica medio-patellaris in dem Kniegelenk mit arthroskopischer Resektion der Plica nacheinander behandelt. 43 Monate nach der Operation wurden 44 Patienten untersucht: 40 Prozent hatten vor der Operation Schmerzen in dem vorderen Teil des Kniegelenkes, 60 Prozent hatten mechanische Symptome. Bei 50 Prozent der Patienten ging ein Knietrauma den Symptomen voraus. Das Gesamtergebnis nach der arthroskopischen Resektion war befriedigend: 80 Prozent mit hervorragendem oder gutem Ergebnis nach dem Lysholm Score und 59 Prozent ganz ohne Symptome. Chondromalacia patellae oder Chondromalacia condyli femoralis und falsche Ausrichtung der Patella hatte keinen Einfluß. Die Schlußfolgerung ist: arthroskopische Resektion einer pathologischen Plica mediopatellaris gibt allgemein gute Ergebnisse — auch wenn eine andere Pathologie des Kniegelenkes vorliegt.
