【摘要】Objective To compare the mechanical axis and alignment of component between conventional total knee arthroplasty(TKA)and TKA under computer-assistde navigation.Methods From May 2007 to December 2009.60 patients with knee osteoarthritis were assigned randomly to receive conventional TKA and computer-assisted navigation TKA with the same type of implant for each knee.In navigation group (group A).there were 11 men and 19 women.with an average age of 69.2±8.3 years.The mean prcoperative alignment deviation was 9.4° ±5.3°.The knee osteoarthritis was rated as grade Ⅲ in 12 cases and grade Ⅳ in 18 cases.In conventional group (group B)、there were 17 men and 13 women,with an average age of 71.9 ± 8.1 years The mean preoperative alignment deviation was 8.9°± 4.8°.The knee osteoarthritis was rated as grade Ⅲ in 17 cases and grade Ⅳ in 13 cases.Alignment of the leg and orientation of components were evaluated on standard pre-and post-operative full-length weight-bearing radiographs and lateral X-rays with reard to the valgus angle and the coronal and sagittal component angles.
