Background:
Preoperative patient characteristics may influence patient choice
for participating in RCT’s.
Purpose / Aim of Study:
This study aimed to compare patient characteristics,
level of pain, physical function and joint space width in patients with severe hip
osteoarthritis (OA) who accepted or refused to participate in a RCT.
Materials and Methods:
In this prospective cohort study a total of 137 pa-
tients with primary hip OA were asked to choose between surgical or non- sur-
gical treatment. We then compared the characteristics of each patient cohort
(demographics, pain level and duration, analgesic use, exercise habits), the radi-
ographic hip OA state and their responses to Hip dysfunction and Osteoarthritis
Outcome Score (HOOS, 0-100) and European Quality of Life Scale (EQ-5D-
5L) questionnaires.
Findings / Results:
The between-group HOOS scores were significantly dif-
ferent in three out of the five HOOS subscales analyzed; HOOSpain 6.1 (95%
CI: 0.3 to 12.5), HOOSADL 8.3 (95% CI: 2.3 to 14.4) and HOOSsport/rec 8.6
(95% CI: 3.2 to 13.9) with higher scores recorded in the non-surgical patient
cohort indicating less symptoms. Overall health status (EQ-5D-5L) showed sur-
gical patients had more problems in all the dimensions except for the EQanxity/
depression responses. The surgical patients had significantly reduced joint space
width (1.2 ± 1.0 mm vs. 1.8 ± 1.2 mm, p = 0.004) and both cohorts had values
below the defined 2 mm cut-off (Jacobsen et al.).
Conclusions:
Patients, who choose surgical treatment had preoperatively more
pain, reduced physical function, lower health status and joint space width com-
pared with patients who choose non-surgical treatment.
