The majority of adverse events associated with CNTKA were minor and comparable with those seen with conventional TKA .
Clinical outcomes were comparable between the two techniques , with longer-term follow-up suggesting that CNTKA provided no benefit over conventional TKA in terms of sustained functional improvements .
At present , it is unclear whether the significant improvements shown in radiological outcomes after CNTKA translate to measurable clinical benefits .
BACKGROUND Conventional total knee arthroplasty ( TKA ) and the more recently available computer-navigated total knee arthroplasty ( CNTKA ) use alternative methods to achieve correct limb alignment .
This systematic review was undertaken to assess the safety and effectiveness of CNTKA compared with conventional TKA .
Randomized control trial comparing radiographic total knee arthroplasty implant placement using computer navigation versus conventional technique.
The aim of this study is to assess the radiological outcome of conventional techniques versus computer-navigated surgery for total knee arthroplasty . Ninety patients with knee arthritis were prospect ively r and omized into 3 groups : conventional technique : extramedullary ( EM ) and intramedullary ( IM ) tibia guide versus computer navigation surgery ( CAS ) . Two surgeons performed all procedures . St and ardized long leg coronal and sagittal x-rays were evaluated by a blinded assessor . Our results showed that CAS had greater consistency and accuracy in implant placement . In the coronal view , 93.3 % in the CAS group had better outcomes compared with EM ( 73.4 % ) and IM ( 60.0 % ) . In the sagittal axis , 90.0 % CAS also had better outcomes compared with EM ( 63.3 % ) and IM ( 76.7 % ) . Computer-navigated total knee arthroplasty helps increase accuracy and reduce " outliers " for implant placement
