Summary
Seventy-one operations are reviewed, in which knees were replaced with the total condylar prosthesis. The follow-up period ranged between 1 and 7 years, with an average of 3.25 years. Osteoarthritis was diagnosed preoperatively in 53 knees and rheumatoid arthritis in 18. The results obtained in cases of osteoarthritis were better than those in cases of rheumatoid arthritis. The prognosis was adversely affected by obesity, preoperative flexion contracture of 30° or more, wound-healing problems, wound infection, and postoperative manipulation under general anesthesia. The overall results were excellent in 48% of cases (34 knees), good in 28% (20 knees), fair in 11.3% (eight knees), and poor in 4.3% (three knees). Failure was experienced in 8.4% of cases (six knees).
Zusammenfassung
Die Resultate von 71 Kniearthroplastiken mit der Totalcondylären Endoprothese wurden überprüft. Der postoperative Zeitabschnitt lag zwischen 1 und 7 Jahren, Durchschnitt 3,25 Jahre. In 53 Kniegelenken war die präoperative Diagnose Osteoarthritis, in 18 rheumatoide Arthritis. Die Resultate in den Osteoarthritis-Fällen waren wesentlich besser als in den rheumatoiden Fällen. Die Prognose wurde negativ beeinflußt durch Übergewicht, eine Flexions Kontraktur von 30° oder mehr, Wundheilprobleme, Wundsepsis und postoperative Manipulation unter Allgemein-Narkose. Die Gesamtresultate waren wie folgt: ausgezeichnet 48% (34 Kniee), gut 28% (20 Kniee), zufriedenstellend 11,3% (8 Kniee), schlecht 4,3% (3 Kniee), Mißerfölg (Entfernung der Endoprothese) 8,4% (6 Kniee).
