Introduction The operative treatment of a secondary gonarthrosis due to RA claims high quality in soft tissue balancing and accurate alignment in total knee arthroplasty (TKA) which are essential for good long-term results. The efficiency of an imageless computer-assisted implantation in TKA was evaluated and compared with conventional technique. Method The authors implanted each 40 TKA either using the imageless computer-assisted or classical surgeon-controlled technique. The quality of implantation was studied on postoperative long-leg coronal and lateral x-rays. Results A postoperative leg axis between 3degrees varus and 3degrees valgus was obtained in 37 patients (92.5%) in the study group and 30 patients (75%) in the control group. Complications influencing the clinical outcome did not occur. Conclusion The use of the imageless Vector-Vision navigation system provides the patient a good chance for longterm survival. Especially the ligament balancing tool appears to be useful. Cutting errors can be detected and intraoperatively corrected.
