Prospective Randomized Trial of Navigated and Conventional TKA

Not Applicable
Completed
Conditions
Osteoarthritis of the Knee
Interventions
Procedure: Implantation of a Total Knee Arthroplasty
Registration Number
NCT01022099
Lead Sponsor
Technische Universität Dresden
Brief Summary

Evaluation of the component position and kinematics after navigated and conventional Total Knee Arthroplasty.

Detailed Description

1. Component position, kinematics After skin closure lateral x-rays were done in different flexion angles in order to evaluate the kinematic behaviour of the TKA.

A full-length standing and a lateral radiograph as well as CT scans of the hip, knee and ankle joint were performed 5 to 7 days postoperatively before discharge.

2. clinical outcome Patient sociodemographic and anamnestic data were collected. The written interview was complemented by the EuroQol questionnaire (release EQ-5D) and the assessment of the patients' functional status (Knee Society Score) one week before surgery and 18 to 24 month after surgery.
