Popis:	It has been reported that the Next Gen total knee system has a more accurate bone cutting technique because all 5 faces of the distal femur can be prepared with only one cutting guide. We report on the short term results of the Nex Gen system as compared to the MG II system and the KU system.57 cases, 68 joints with tatal knee arthroplasty, operated on from June 1994 to December 1996, were followed. There were 53 cases, 63 joints, of OA and 3 cases, 5 joints, of RA. Knee prosthesis types were 42 Nex Gen, 13 MG II and 13 KU. These were compared and evaluated both clinically and radiographically.The mean range of motion of the Nex Gen cases went from 115.9° preoperatively to 114.1° postoperatively. The mean J. O. A. score for the Nex Gen cases improved from 47.1 points to 85.6 points. Infection, dislocation and breakage of the prosthesis were not noted. The subsidence (2mm) of the medial part of the tibial component was noted on radiographs 6 months postoperatively in one case, but it did not progress after that. Each component was correctly aligned and maintained position. The short term results of the Nex Gen system are good.
