All the knees were performed by a single surgeon using the same cruciate sacrificing implants. In our study we used CT based PSB to compare with CI. Postoperative mechanical femoro-tibial angle(MFT angle) was measured on long leg x-rays using picture archiving and communication system(PACS). We compared mechanical alignment achieved using PSB and CI in TKA using statistical analysis.RESULTS: The PSB group(group 1) included 17 females and seven males while in CI group(group 2) there were 15 females and eight males. The mean age of patients in group 1 was 60.5 years and in group 2 it was 60.2 years. The mean postoperative MFT angle measured on long-leg radiographs in group 1 was 178.23°(SD = 2.67°, range: 171.9° to 182.5°) while in group 2, the mean MFT angle was 175.73°(SD = 3.62°, range: 166.0° to 179.8°). There was significant improvement in postoperative mechanical alignment(P value = 0.001), in PSB group compared to CI. Number of outliers were also found to be less in group operated with PSB(7 Knee) compared to those operated with CI(17 Knee).CONCLUSION: PSB improve mechanical alignment after total knee arthroplasty, compared to CI. This may lead to lower rates of revision in the PSB based TKA as compared to the conventional instrumentation.展开更多
