| Objective: To investigate the correlation between the rehabilitation procedures following ACL reconstruction and the bone tunnel extansion in athletes. Methods: A total of 29 cases were selected and divided into the control group (A, 9 cases), the traditional rehabilitation group (B, 10 cases) and the rapid rehabilitation group (C, 10 cases). The three groups were given different rehabilitation procedures. The diameter of the bone tunnel was measured by magnetic resonance imaging at 1st week, 6th week, 24th week and 1st year after rehabilitation. Results: All the bone tunnels were gradually widened in three groups after ACL reconstruction at 6th week, 24th week and 1st year after rehabilitation (P<0.05, 0.01), but there was no statistically significant difference between 24th week and 1st year. The bone tunnel expanding ratio in group B and group C was significantly higher than in group A (P<0.05, 0.01), and that in group C was higher than in group B (P<0.05, 0.01). Conclusion: Different rehabilitation procedures for patients after ACL reconstruction have different impacts on bone tunnel expansion. Postoperative rehabilitation program can widen the bone tunnels. Attention should be paid to timing of rehabilitation training scheme. |
