  * Comparison of patients with KL grade 0-2 and 3-4 at preoperative assessment by means of Mann- Whitney U or Chi Square tests where appropriate. Significance level < 0.05.
Crude and adjusted changes in health-related quality of life and functional outcome measurements in patients with mild or severe radiographic OA
The crude (unadjusted) mean change scores (postoperative scores minus preoperative score) in patients with mild or severe radiographic OA are shown in Tables 2a and 2b. In THA patients, the mean change scores were statistically significantly higher in patients with KL 3–4 than in patients with KL 0–2 with respect to HOOS “Symptoms”, EQ score, SF “Physical functioning” and “Bodily pain”; and SF “PCS”. In TKA patients, there were no statistically significant differences in change
