Rotating knee prosthesis. Surface or hinge replacement?

Until the early 1990's our experience in Total Knee Replacement (TKR) was based on AGC 2000, Tricon M and MG implants. Starting from 1992 we decided to use a rotating knee prosthesis. At that time in Italy there were many knee replacement devices with rotating elements: Oxford, LCS, Rotaglide and Endomodel from Link. The Endomodel rotating prosthesis was our choice and between 1992 and 1995 we implanted 142 prosthesis of this type, 128 as primary replacement and 14 as TKR revision. The overall results were good or excellent in most of our cases (Fig. 1). During this period we had 6 dislocations of the device (Fig. 2) and 4 infections: 1 from our service and 3 coming from other hospitals.

[Conventional radiology in the choice of surgical treatment of gonarthrosis].

Gonarthrosis is a pathologic condition the incident of which is high in people over 50. Its etiologic factors are varus-valgus deformities, traumatic lesions, meniscal tears, osteochondritis, and metabolic diseases. The authors report their experience with the setting of a radiographic protocol for the study of 100 patients over 50. The protocol allowed both detection and quantification of: varus and valgus deformities studied in weight-bearing (teleradiography in weight-bearing) and extensor mechanism malalignment (tangential views); chondral wear of femoral and tibial joints (varus and valgus radiographs); varus and valgus knees instability (varus and valgus radiographs). The results are extremely satisfactory: this protocol allowed correct gonarthrosis grading and the evaluation of such associated lesions as lateral instability. The surgeon is thus provided with the essential elements for the choice of the correct treatment.
