Brief Summary

  1. 1.Prospective follow-up and comparative analysis of early, midterm, and long-term surgical results and complications between navigation assisted TKA and conventional TKA.
  2. 2.Prospective comparative analysis of cytokines (including ICAM, VCAM, and PECAM) from blood, tissues, and drainage between navigation assisted TKA and conventional TKA.
  3. 3.Prospective follow-up of surgical results of navigation-assisted TKA.

Conditions

Outcome Measures

Primary Outcomes (1)

  • ELISA analysis to compare concentrations of target molecules in serum and hemovac drainage between two groups

    We collect the serum and sample from hemovac drainage 24 hours after the surgery, to measure the concentrations of target molecules (ICAM, VCAM, PECAM).

    24 hours after surgery

Study Arms (2)

Procedure: Navigation total knee arthroplasty

Conventional total knee arthroplasty

Conventional total knee arthroplasty

Procedure: Conventional total knee arthroplasty

Interventions

computer assisted navigation total knee arthroplasty without femur intramedullary involvement

Navigation total knee arthroplasty
