Results of patients with slight preoperative lower extremity alignment deviation
For patients with slight preoperative lower extremity alignment deviation, the postoperative HKA angle deviation was 1.56±0.95° in the RAS group and 2.25±1.54° in the CON group. The CFCA deviation was 0.79±0.62° in the RAS group and 0.99±0.73° in the CON group. The CTCA angle deviation was 0.90 (1.90)° in the RAS group and 1.80 (0.92)° in the CON group. The SFCA angle deviation was 1.20 (2.20)° in the RAS group and 1.20 (1.63)° in the CON group. The STCA angle deviation was 1.98±1.60° in the RAS group and 1.92±1.34° in the CON group. There was no significant difference in angle deviation between the two groups (Individual component positions and lower limb alignment in patients with slight preoperative lower extremity alignment deviationCFCA, coronal femoral component angle; CON, conventional techniques; CTCA, coronal tibial component angle; HKA, hip–knee–ankle; RAS, robotic‑assisted system; SFCA, sagittal femoral component angle; STCA, sagittal tibial component angle.There was no significant difference in the rate of outliers for SFCA, STCA, CTCA, and CFCA between the two groups (Outliers for component positions and lower limb alignment among patients with slight preoperative lower extremity alignment deviationCFCA, coronal femoral component angle; CON, conventional techniques; CTCA, coronal tibial component angle; HKA, hip–knee–ankle; RAS, robotic‑assisted system; SFCA, sagittal femoral component angle; STCA, sagittal tibial component angle.
There was no significant difference in postoperative KSS, postoperative VAS score, and postoperative ROM between the two groups (Postoperative data at 12 weeks for patients with slight preoperative lower extremity alignment deviationCON, conventional techniques; KSS, Knee Society score; RAS, robotic‑assisted system; ROM, range of motion; VAS, 10-cm visual analog scale.
