Objective To analyze the changes in parameters such as center of pressure area (COPA) and center of pressure speed (COPS) under the influence of visual factors in patients at early stage after anterior cruciate ligament reconstruction (ACLR) and 1 year after the surgery. Methods A total of 17 patients with ACLR were included and tested for data such as COPA and COPS in early postoperative period and 1 year after the surgery, and 17 healthy subjects were matched as control group. The standing balance test with different visual states of open and closed eyes was performed and correlation analysis was conducted for each measurement state. Results During the double-foot standing test, there were significantly difference in COPA and COPS between the eyes-open and eyes-closed states in short-term group (P<0. 05). There were statistically differences in COPS between the eyes-open and eyes-closed states in long-term group (P<0. 001). The difference between the groups was statistically significant during standing on the healthy side (P<0. 05), and the difference between the groups was not statistically significant during standing on the injured side (P<0. 05). During standing on the healthy side with eyes open, COPA was higher in long-term group than that in the short-term and control groups, and COPS was lower in control group than that in short-term and long-term groups (P<0. 01). During standing on the healthy side with eyes closed, COPA was lower in control group than that in short-term and long-term groups, and COPS was lower in control group than that in long-term group (P< 0. 01). Positive correlations in COPA and COPS were found between eyes-open and eyes-closed states during double-foot standing, between injured side and double-foot standing with eyes open, between healthy side and injured side during standing with eyes open, and between healthy side and injured side during standing with eyes closed. Conclusions The analysis on COP-related data for patients with ACLR in standing position indicates that the vision has an important influence on postural stability control. The patients at 1 year after ACLR surgery show greater fluctuation in stability during double-foot and single feet standing compared with normal people. In clinical practice, it is suggested that long-term postoperative training should be strengthened to consolidate the rehabilitation effect, which also has a certain guiding role in carrying out long-term assessments and developing precise training plans, so as to prevent prolonged functional deterioration and reduce the risk of reinjury after surgery.
