Achieving Accurate Ligament Balancing Using Robotic-Assisted Unicompartmental Knee Arthroplasty

Table 1

Comparison of the intra-operative balance plan and ligament balance measurements following component implantation. Data is expressed as mean ± standard error of the mean in millimeters.

Flexion angle	Balance plan	After implantation	Change in balance	𝑃 value
0°	0.34 ± 0.12	0.08 ± 0.18	−0.26 ± 0.17	𝑃>0.05
30°	1.31 ± 0.13	0.78 ± 0.17	−0.53 ± 0.18	𝑃<0.05^∗
60°	−0.28 ± 0.11	−0.33 ± 0.14	−0.04 ± 0.15	𝑃>0.05
90°	−0.49 ± 0.12	−0.32 ± 0.13	0.16 ± 0.13	𝑃>0.05
110°	0.03 ± 0.16	−0.07 ± 0.19	−0.10 ± 0.14	𝑃>0.05

∗A 𝑃 value less than 0.05 was considered statistically significant.
