The necrotic area was not significantly different at 9 months and 24 months after the operation. b The HHS was significantly higher at 9 months after surgery than before surgery (p < 0.05). c The VAS score was significantly lower at 9 months after the operation than before the operation (p < 0.05). The VAS was slightly lower at 24 months after the operation (1.87 ± 0.60) than at 9 months after the operation (p > 0.05)
