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 .
Does accurate anatomical alignment result in better function and quality of life? Comparing conventional and computer-assisted total knee arthroplasty.
This is a r and omized prospect i ve controlled trial comparing the alignment , function , and patient quality -of-life outcomes between patients undergoing conventional ( CONV ) and computer-assisted ( CAS ) knee arthroplasty . One hundred and fifteen patients ( 60 CAS , 55 CONV ) underwent cemented total knee arthroplasty .  Three patients were lost to follow-up . Eighty-eight percent ( CAS ) vs 61 % ( CONV ) of knees achieved a mechanical axis within 3 degrees of neutral ( P = .003 ) . Aligning femoral rotation with the epicondylar axis was accurately achieved in CAS and CONV with no significant difference . Patients with coronal alignment within 3 degrees of neutral had superior International Knee Society and Short-Form 12 physical scores at 6 weeks , 3 months , 6 months , and 12 months after surgery . Computer-assisted total knee arthroplasty achieves greater accuracy in implant alignment and this correlates with better knee function and improved quality of life
