Detaljeret beskrivelse
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.
- 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.

Aktiv komparator: navigated TKA
|
In all patients a cemented, unconstrained, cruciate-retaining TKA with a rotating platform (ScorpioTM PCS, Stryker Orthopaedics, Mahwah, NJ) was implanted. No patellar resurfacing was performed. A medial parapatellar approach with a femur-first preparation was done in all cases. The Stryker Navigation System, Knee Navigation Software V3.1 (Stryker Orthopaedics, Mahwah, NJ) was used for computer-assisted implantation. The conventional implantation was performed with femoral intramedullary and tibial extramedullary standard alignment guides.
