Table 2.
Comparison of postoperative outcomes between direct anterior and anterolateral/posterior surgical approaches.
| Postoperative outcome | Direct anterior approach (N = 20) | Anterolateral or posterior approach (N = 32) | P value |
|---|---|---|---|
| Complication | 0 (0.0%) | 5 (15.6%) | .089 |
| Reoperation | 0 (0.0%) | 2 (6.3%) | .30 |
| Dislocation | 0 (0.0%) | 0 (0.0%) | 1.00 |
| Harris Hip Score | 94 (62, 100) | 81 (44, 100) | .072 |
| Hospital length of stay (d) | 3 (2, 10) | 5 (2, 8) | .001 |
| Discharge destination | .014 | ||
| Home | 8 (40.0%) | 3 (9.4%) | |
| Skilled nursing facility | 12 (60.0%) | 29 (90.6%) | |
| Postoperative ambulation status | .52 | ||
| Community ambulator | 20 (100.0%) | 30 (93.8%) | |
| Household ambulator | 0 (0.0%) | 2 (6.3%) | |
| Worsening of ambulation status from preoperative to postoperative | 0 (0.0%) | 1 (3.1%) | 1.00 |
The sample median (minimum, maximum) is given for continuous variables. P values result from a log-rank test (complication, reoperation, dislocation), a linear regression model that was adjusted for follow-up length (Harris Hip Score), a Wilcoxon rank sum test (hospital length of stay), or Fisher’s exact test (discharge destination, postoperative ambulation status, and worsening of ambulation status from preoperative to postoperative).
Bold indicates a statistical significance (P < .05).
