Is the use of computer navigation in total knee arthroplasty improving implant positioning and function? A comparative study of 198 knees operated at a Norwegian district hospital

Abstract: BackgroundThere are few Scandinavian studies on the effect of computer assisted orthopedic surgery (CAOS) in total knee arthroplasty (TKA), compared to conventional technique (CON), and there is little information on effects in pain and function scores. This retrospective study has evaluated the effects of CAOS on radiological parameters and pain, function and quality of life after primary TKA.Methods198 primary TKAs were operated by one surgeon in two district hospitals; 103 CAOS and 95 CON. The groups were e… Show more

“…Although improvements in implant alignment and hospitalization times have been consistently demonstrated with the use of intraoperative technology [15, 35, 38, 45], it remains unclear whether this translates into superior clinical and functional outcomes compared to manual procedures [1, 6, 7, 11, 43, 52]. This partly stems from the limitations of the current literature, including inconsistency in patient reported outcome measures (PROMs) among individual studies [1], as well as limited pooled data analyses among systematic reviews.…”

“…However, even with confirmed alignment accuracy, the clinical outcomes of patients present another aspect of navigation that is widely debated [ 7 , 9 , 13 , 18 , 20 , 24 , 31 , 37 44 ]. Many surgeons have made note of marked improvement in groups of navigated patients.…”

“…Computer‐assisted surgery enables the surgeon to adjust the component placement according to the patients anatomy [6] and to restore leg alignment with higher accuracy than in conventional [4, 12, 17, 32] or in patient‐specific instrumented TKA (PSI) [40]. Additionally, the surgical philosophy (gap balancing vs. measured resection technique) may have an influence on the relationship between “femoral offset changes” and “tibial slope” and the achieved MKF.…”
