Analysis of the effect and gait analysis of biplane ascending high tibial osteotomy and descending osteotomy for varus knee osteoarthritis

Objective To investigate the effect and gait analysis of the treatment of biplane ascending high tibial osteotomy and descending osteotomy for varus knee osteoarthritis. Methods A total of 32 hospitalized patients with inverted knee osteoarthritis from January 2017 to June 2019 were selected. They were divided into two groups according to the surgical method. The HSS knee function score, VAS score, femoral tibial angle (FTA), tibial posterior slope, Insall-Salvati index (patella height) changes, and changes in gait time and space parameters, gait motion parameters, and gait motion mechanics parameters of the two groups were observed. Results The HSS knee function score, VAS score, femoral tibial angle, tibial posterior slope, and Insall-Salvati index of the two groups of patients six months after the operation were significantly different from those of the preoperative group (P<0.05). The Insall-Salvati index in the second half of the year was statistically significant (P<0.05). In the comparison of the gait time and space parameters of the two groups of patients, including gait speed, gait frequency, stride length, and gait cycle, the differences in each index in the group six months after the operation were statistically significant (P<0.05). There were statistically significant differences in the pace and stride length of the patients in the six months after the operation (P<0.05). The gait motion parameters of the two groups of patients include the maximum flexion angle of the support phase, the minimum flexion angle of the support phase, the mid-support phase extension angle, and the swing phase flexion angle. In the comparison of the two groups six months after the operation, there are differences in the indicators compared with the preoperative comparison. It was statistically significant (P<0.05), and there was no statistically significant difference between the groups six months after the operation (P>0.05). In the comparison of the gait motion mechanics parameter, that is, the adduction torque, the difference between the two groups in the six months after the operation was statistically significant (P<0.05), and the knee joint adduction in the two groups was six months after the operation. There was no statistically significant difference between the torque groups (P>0.05). Conclusion High tibial osteotomy can significantly improve the gait of patients with knee osteoarthritis, and high tibial biplane osteotomy is more advantageous for preserving the height of the patella.
