[The Interplanta system model knee joint prosthesis. Preliminary results]. / Das Schalen-Kniegelenkendoprothesen-System Modell Interplanta (SKI). Erster Erfahrungsbericht.

ABSTRACT

The SKI-knee joint is used since three years. Our experiences comprise 220 cases up to now. The follow-up time is still short, but the implant, which is partially designed very close to normal anatomy and on the other hand regards fundamental biomechanical aspects is showing a comparably low incidence of complications. The complications specifically due to the endoprosthetic system sums up to 10%. It is obvious that patellar complications are leading. This fact should be seen in close connexion to the anatomical design of the femoral component. With increasing experience these problems are diminished. Causes and potential elimination of patellar complications are discussed. Surgical procedure, especially advantages in comparison with other knee joints are described. The SKI-System in combination with its aligning instruments allow the surgeon anatomical reconstruction, very exact alignment of the implant and precise correction of preexisting deformities. In general the results are encouraging in comparison with formerly used knee joints after the same follow-up period.
