Table 2.
Age- and gender-adjusted physical functions subscales at baseline, and five-year follow-up changes in the scaled Orton Hip Score (sOHS) among THA patients
| Baseline information | Change from baseline to five years after | |||||
|---|---|---|---|---|---|---|
| (before the THA operation) | THA operation | |||||
| Points | Unilateral THA | Bilateral THA | Unilateral THA | Bilateral THA | p-value* | |
| Range | Mean (SD) | Mean (SD) | Mean (95% CI) | Mean (95% CI) | ||
| Pain | 0–40 | 16 (11) | 17 (10) | 23 (22 to 24) | 23 (20 to 26) | 0.86 |
| Walking distance | 0–15 | 9 (4) | 9 (4) | 5 (4 to 5) | 6 (5 to 7) | 0.16 |
| Limping | 0–5 | 4 (1) | 4 (1) | 1 (0.9 to 1.1) | 1 (1.0 to 1.5) | 0.41 |
| Support | 0–5 | 4 (1) | 4 (1) | 1 (0.5 to 0.7) | 0.6 (0.3 to 0.9) | 0.86 |
| Public Transport | 0–5 | 3 (2) | 3 (2) | 1 (1.1 to 1.4) | 2 (1 to 2) | 0.28 |
| Stairs | 0–5 | 3 (1) | 3 (1) | 1 (1.1 to1.4) | 1 (1 to 2) | 0.85 |
| Activities (shoes, socks) | 0–5 | 2 (2) | 2 (2) | 2 (1.6 to 2.0) | 2 (2 to 3) | 0.66 |
| Total sOHS (0-100) | 0-100** | 53 (20) | 53 (19) | 42 (40 to 44) | 44 (40 to 49) | 0.19 |
* p-values were adjusted for age and sex and corrected using Hommel’s multiple comparison procedure
** Total sOHS is scaled 0 to 100 (0 indicates the worst pain and physical function and 100 indicates no pain at all and the best physical function)
