Key takeaways:
- Together, accelerated and conservative rehabilitation groups had improvements in postoperative outcome scores.
- Accelerated rehabilitation had slight differences in outcome scores vs. conservative rehabilitation.
NEW ORLEANS — Results presented here showed a conservative rehabilitation protocol after hip arthroscopy had statistical but not clinical differences in outcome scores compared with an accelerated rehabilitation protocol.
Michael B. Banffy, MD, and colleagues developed and implemented an accelerated rehabilitation protocol for patients who underwent hip arthroscopy for femoroacetabular impingement between April 2020 and March 2021, and compared it with a conservative rehabilitation protocol performed between April 2018 and March 2020. Banffy noted patients in the conservative rehabilitation group had 50% weight-bearing and crutches for 3 weeks postoperatively with a delay in start of physical therapy for 2 to 3 weeks, while the accelerated rehabilitation protocol consisted of immediate weight-bearing and crutches and an early progression to physical therapy within 1 to 2 days after surgery.
Researchers identified any complications, including revision, and collected VAS, the modified Harris Hip Score and single assessment numerical evaluation (SANE) score.
“We also looked at the [minimal clinically important difference] MCID and utilized a distribution method to calculate this to compare the differences between the two groups,” Banffy said in his presentation at the Arthroscopy Association of North America Annual Meeting.
Both groups combined had significant improvement between preoperative and postoperative patient-reported outcome scores, according to Banffy. However, propensity score results showed patients in the accelerated rehabilitation group had slightly increased VAS scores and slightly decreased SANE score and modified Harris Hip Scores at 1 year postoperatively compared with the conservative rehabilitation group.
“When we compared this between group difference to the MCIDs, it was not significant,” Banffy said. “Although there was statistical significance, there was no clinical significance, and that was on the VAS, modified Harris Hip Score, as well as the SANE score.”
