Pre- and Post-Operative Pain Intensity and Physical Activity Levels in Individuals with Acetabular Dysplasia Undergoing Periacetabular Osteotomy: A Prospective Cohort Study.
Naif Alrashdi, Robert Motl, Elroy Aguiar and 4 others
PMID 38835978WHAT IT FOUND
Pain improved in 23 people after hip arthroscopy, periacetabular osteotomy, and standardized rehabilitation.
Pain was better by one month and continued to six months. Device-measured and self-reported activity levels were not different by six months.
Key findings
01Pain ratings improved over the follow-up period, with differences at one month and later compared with before surgery.
02Accelerometer-measured sedentary time, light activity, moderate-to-vigorous activity, and daily steps were not different between before surgery and six months after surgery.
03Self-reported moderate-to-vigorous activity was much higher than accelerometer-measured activity before and after surgery.

What it does not show
Only 23 participants completed all measures, so the study may have missed real differences in activity levels. All participants were treated by one surgeon at one institution, and 22 were female, so results may not apply to other patients, surgical techniques, or rehabilitation programs. Participants had hip arthroscopy before the osteotomy and then followed one standardized rehabilitation program, so the effect of any single component cannot be separated. Activity was measured only before surgery and at six months, so changes during the first six months were not tracked. The waist-worn accelerometer may not have captured upper-body activity, and the self-report questionnaire may have been misunderstood or affected by recall.
Declared interests
The authors declared no conflicts of interest. The work was funded by the NIH National Rehabilitation Research Resource to Enhance Clinical Trials REACT Scholar Award and by the Deanship of Postgraduate Studies and Scientific Research at Majmaah University under project R-2024-1049.
The easy way to misread this
Do not conclude that periacetabular osteotomy alone improved pain or increased activity. Participants also had hip arthroscopy and standardized rehabilitation, and activity levels were not different by six months.
