Comparison of the results at followup in the two groups
| Type of result | Steroids group (143) | DBM + BMC group (41) | p value |
|---|---|---|---|
| Healing rate (%) | 54 (38) | 29 (71) | < 0.001 |
| Number of treatments* needed to obtain healing (mean ± SD) | 1.66 (± 0.6) | 1.1 (± 0.3) | < 0.0005 |
| Number of injections needed to obtain healing (mean ± SD) | 4.3 (± 3.9) | 1.1 (± 0.3) | < 0.0005 |
| Final Neer score (%) | |||
| I | 11 (7.7) | 8 (19.5) | < 0.002 |
| II | 43 (30) | 21 (51.2) | < 0.002 |
| III | 56 (39.2) | 7 (17) | < 0.002 |
| IV | 33 (23) | 5 (12.2) | < 0.002 |
* In the DBM + BMC group, one treatment is equal to one injection; in the steroid group, one treatment can be more than one injection; DBM = demineralized bone matrix; BMC = bone marrow concentrate.
