Objective
To determine whether differences exist in patients’ subjective feelings, daily life, and surgical satisfaction between those who underwent surgery for developmental dysplasia of the hip (DDH) using patient‐specific instruments (PSIs) and those who underwent traditional surgical total hip arthroplasty (THA).
Methods
We selected 30 adult patients with various types of DDH who underwent surgery during 2016–2017 at our hospital. The patients were divided into PSI surgery group and the traditional surgery group. All patients underwent follow‐up, and we collected data on the Harris Hip Score, Oxford University Hip Score (OHS), Forgotten Joint Score (FJS‐12), Visual Analogue Scale (VAS) score, patient satisfaction score, intraoperative surgical time, amount of bleeding and postoperative complications incidence for both groups. We then performed statistical analyses on the data.
Results
The Harris Hip Score, OHS, VAS score, patient satisfaction score, and mean bleeding volume did not differ statistically significantly (t‐tests, P > 0.05). No statistically significant differences were found between surgical groups in the incidence of complication and sub‐trochanteric osteotomy, or in the surgical side (chi‐square tests, P > 0.05). For the experimental group, the FJS‐12 score was 80.0 ± 12.0, and for the control group the score was 68.5 ± 16.1. The operative time of the experimental group was 138.4 ± 32.2 min, while that of the control group was 88.9 ± 26.8 min. The values of these data differed significantly (t‐tests, P < 0.05).
Conclusions
The novel PSI designed by our group has certain advantages for the short‐term subjective feelings of patients after THA, but it may cause prolonged operative times.
