Onsen National Hospital 40 primary uncemeneted total knee arthroplasties (MG II) were performed in 32 patients with osteoarthritis.The average age was 73.0 years at the time of surgery.The follow-up period was an average of 5. 6 years (range; 5 to 6.6 years).Clinical evaluations based on the Japanese Orthopedic Association score indicated significant improvements from preoperative to the most recent follow-upexamination.There was no evidence of rentogenographic failure in the femoraland tibial

These mid-term results of uncemented MG II TKAs proved satisfactory in osteoarthritis. However, a longer follow-up period is necessary for problems related to the patellarcomponent even in MG II TKAs, because mal-alignment of the patella-femoral jointhas been observed in 4 knees.
