title: [Results in patello-femoral joint replacement in various knee endoprostheses (Type GSB and ES)].
abstract: 105 patients with 137 total knee replacements (105 model GSB, 32 model ES) were reexamined 4.3 years (2 to 9.7 years) postoperatively. 63.9 percent suffered from chronic polyarthritis. The clinical result (Insall 100-point score) averaged 73.6 points (78.2 ES-, 71.7 GSB II-knees). In 28.6 percent of the GSB- and 3.1 percent of the ES-knees osteolyses of the patella were apparent. Subluxation or complete dislocation of the patella was present in 85.7 percent of the GSB- and 25 percent of the ES-knees. The result was dependent on the preoperative knee axis, patellar height and the implant site of the tibial component. Revisions with complete removal of the inlay were most successful.
