Results of patients with severe preoperative lower extremity alignment deviation
Among patients with severe preoperative lower extremity alignment deviation, the postoperative HKA angle deviation was 2.09±1.18° in the RAS group and 3.57±2.73°in the CON group; the difference was statistically significant (Individual component positions and lower limb alignment in patients with severe 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, and CTCA between groups. The rates of the postoperative HKA angle outlier in the RAS group and CON group were 5.1 and 44.7%, respectively, and the difference was statistically significant (Outliers for component positions and lower limb alignment among patients with severe 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 severe preoperative lower extremity alignment deviation.CON, conventional techniques; KSS, Knee Society score; RAS, robotic‑assisted system; ROM, range of motion; VAS, 10-cm visual analog scale.
