OTHERInterventions
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.
Eligibility Criteria
You may qualify if:
- primary or secondary osteoarthritis of the knee
- indication to TKA
- a mechanical axis between 20° varus and 5° valgus
- signed informed consent
You may not qualify if:
- previous hemi- or total arthroplasty
- severe instability that could not be treated with an unconstrained, cruciate-retaining TKA
