Key takeaways:
- Arthroscopic labral repair may yield superior outcomes for femoroacetabular impingement vs. labral reconstruction.
- Repair was associated with a decreased risk of conversion to arthroplasty vs. reconstruction.
For patients with acetabular labral tears associated with femoroacetabular impingement, labral repair may yield superior outcomes with a decreased risk of conversion to arthroplasty vs. labral reconstruction, according to published results.
Grant J. Dornan, MS, director of clinical outcomes research at the Steadman Philippon Research Institute, and colleagues used a prospectively enrolled patient outcome registry to analyze the treatment effect of 998 arthroscopic labral repairs and 150 arthroscopic labral reconstructions for acetabular labral tears associated with femoroacetabular impingement between 2006 and 2018.
Outcome measures included hip outcome score for activities of daily living (HOS-ADL), modified Harris Hip Score (mHHS), WOMAC score, SF-12 physical component summary (SF-12 PCS) score and patient satisfaction.
Dornan and colleagues found 724 labral repairs and 129 labral reconstructions had available minimum 2-year outcome data.
At minimum 2-year follow-up, labral repair was associated with superior SF-PCS scores (55 vs. 54), mHHS (86 vs. 85) and HOS-ADL (93 vs. 90) compared with labral reconstruction.
Dornan and colleagues also found labral repair was associated with a significantly lower risk of conversion to total hip arthroplasty. According to the study results, repair was associated with a 7% conversion to THA rate at a median follow-up of 5.8 years, while reconstruction was associated with a 20% conversion to THA rate at a median follow-up of 5.3 years.
“These data support the use of labral repair in the primary setting of labral tears and the reservation of labral reconstruction for more advanced labral pathology or for revision cases,” Dornan and colleagues wrote in the study.
