Summary

Gap balance type and measured resection type total knee arthroplasty (TKA) have different influence on the rotation of femoral component.In this study, the rotation of patients received different type of TKA will be estimated and analysed through preoperation and postoperation knee joint CT scan.

Detailed description

This is a multicenter, double-blined, randomized controled clinical trial. 98 patients from 2 clinical center will be recruited with primary knee osteoarthritis, undergoing a primary TKA. The patients will be randomly divided into two groups , the measured resection group and the gap balance group.And the gap balance technique in this study will be achieved with a ligament tensor used during TKA. Femoral component rotation will be assessed from the preoperative and postoperative CT scans.

Conditions

• Osteoarthritis, Knee

Interventions

Type	Name	Description
PROCEDURE	the gap balance type of total knee arthroplasty	A gap balance type of total knee arthroplasty surgery will be performed.The gap balance group will receive this kind of intervention.
PROCEDURE	the measured resection type of total knee arthroplasty	A measured resection type of total knee arthroplasty surgery will be performed.The measured resection group will receive this kind of intervention.
