الوصف: Background: Restoring good alignment after total knee replacement (TKR) is still a challenge globally, and the clinical efficiency of patient-specific instruments (PSIs) remains controversial. In this study, we aimed to explore the value and significance of three-dimensional printing PSIs based on knee joint computed tomography (CT) and full-length lower extremity radiography in TKR. Methods: Between June 2013 and October 2014, 31 TKRs were performed using PSIs based on knee joint CT and full-length lower extremity radiography in 31 patients (5 males and 26 females; mean age: 67.6 ± 7.9 years; body mass index [BMI]: 27.4 ± 3.5 kg/m2). Thirty-one matched patients (4 males and 27 females; mean age: 67.4 ± 7.2 years; mean BMI: 28.1 ± 4.6 kg/m2) who underwent TKR using conventional instruments in the same period served as the control group. The mean follow-up period was 38 months (31–47 months). Knee Society Score (KSS), surgical time, and postoperative drainage volume were recorded. Coronal alignment was measured on full-length radiography. Results: Twenty-three (74.2%) and 20 (64.5%) patients showed good postoperative alignment in the PSI and control groups, respectively, without significant difference between the two groups (χ2 = 0.68, P = 0.409). The mean surgical time was 81.48 ± 16.40 min and 72.90 ± 18.10 min for the PSI and control groups, respectively, without significant difference between the two groups (t = 0.41, P = 0.055). The postoperative drainage volume was 250.9 ± 148.8 ml in the PSI group, which was significantly less than that in the control group (602.1 ± 230.6 ml, t = 6.83, P < 0.001). No significant difference in the KSS at the final follow-up was found between the PSI and control groups (91.06 ± 3.26 vs. 90.19 ± 3.84, t = 0.95, P = 0.870). Conclusions: The use of PSIs based on knee joint CT and standing full-length lower extremity radiography in TKR resulted in acceptable alignment compared with the use of conventional instruments, although the marginal advantage was not statistically ...
