The goal of this study is to compare the clinical and radiographic results of total knee
arthroplasty (TKA) implanted with or without computer assistance. Methods and
materials: We present a prospective study, 105 patients (mean 71.5 years) divided
into two groups: TKA computer assisted surgery (n=55) and classic (n=50). All the
patients were operated by the same surgeon and had the same implant design. The
clinical and radiographic parameters were analysed preoperatively and
postoperatively (2, 6, 12 months) by one observer. A statistically analysed was done
with a p0, 05). The implant positioning was comparable (angle computer
surgery HKA = 179 ± 1.58° versus 176° ± 3.6). The a ctive flexion, at 6 months
postoperative, was significantly better in the classic TKR (107 º versus 101º,
p=0.016). Discussion – Conclusion: This study didn’t show a significant difference
between the TKR performed with or without computer assistance. This technique
allows a better positioning of the implants and improves the reproducibility of the
technique, but when the surgeon has a skilled experience the difference between
isn’t significant.
