In the group A the patients had an accelerated postop. rehabilitation. The group B received a standard rehabilitation protocol. Each group has been evaluated prospectively with VAS, UCLA and Constant scores pre-op and during follow-up.
The VAS score of group A (PDGF) was pre-op. 5.6 and at 1 year 1.4. The VAS score of group B (no PDGF) was pre-op. 5.2 and at 1 year 1.4. The UCLA score of group A was pre-op. 16 and at 1 year 33.8. The UCLA score of group B was pre-op. 16.7 and at 1 year 32.9. The Constant score of group A was pre-op. 53 and at 1 year 90.7. The Constant score of group B was pre-op. 54.2 and at 1 year 90.1. The complete statistical analysis of the data showed no significant differences in the results of the two groups (p<
0,01), with every kind of scores, VAS, UCLA and Constant, at the final follow-up of 1 year.
The statistical analysis of the data shows a direct correlation between anxiety level and pain perception in the pre surgical period. Furthermore, patients with higher level of anxiety showed an increased use of analgesic drugs in the post surgical period (the higher dosage prescribed on demand). The unpleasant memory persistence is however mitigated in the same group, possibly due to much drug assumption.
