Abstract EN
Background.
With the development of three-dimensional printing (3DP) technology, the patient-specific instrumentation (PSI) has been widely applied in total knee arthroplasty (TKA).
The purpose of this study was to compare the gait parameters of patients with 3DP personalized guide-assisted and standard TKA.
Methods.
Retrospective analysis of the advanced knee OA cases in our hospital between June 2017 and June 2018 was conducted.
30 cases received 3DP personalized guide-assisted TKA (group A), and 60 patients who underwent standard TKA during the same period were in group B and group C according to the computed tomography (CT) measurement results, each with 30 cases.
Hip–knee–ankle angle (HKA), patella transverse axis-femoral transepicondylar axis angle (PFA), and gait parameters were statistically analyzed.
The function was assessed by Hospital for Specific Surgery (HSS) and Knee Society Score (KSS).
Results.
The mean follow-up period was 12.3 months in the three groups.
The knee max flexion angle at the swing phase of group A was larger than group B and group C (P<0.05), there was no statistically significant difference in other gait parameters.
The mean PFA of group A was smaller than that of group B and group C (P<0.05).
While, the HKA, HSS, and KSS scores of three groups showed no significant difference.
Conclusion.
3DP personalized guide technology could improve the gait parameters after surgery, specifically reflected in the knee max flexion angle at the swing phase.
It could also assist in the reconstruction of more accurate patellar tracking and rotational alignment in TKA, avoiding the occurrence of insufficient or excessive extorsion.
