Figure 2.

Analysis of total HSS scores of patients ($\overline{x}\pm s$, points). The horizontal axis of from left to right represents before surgery (T₀), 3 months after surgery (T₁), 6 months after surgery (T₂), 12 months after surgery (T₃), and 24 months after surgery (T₄), and the vertical axis represents the total HSS score (points). The total HSS scores at T_0, T_1, T_2, T₃, and T₄ were (42.1 ± 5.6), (71.2 ± 6.9), (81.5 ± 6.3), (85.1 ± 5.7), and (92.6 ± 5.9), respectively. ^∗Comparison of the time nodes after surgery with T₀ (P < 0.05).
