This systematic review and meta-analysis compared clinical outcomes after arthroscopic segmental or circumferential acetabular labral reconstruction. Across 28 studies involving 1817 hips, both techniques were associated with significant improvements in reported function and pain, with no significant between-group differences in patient-reported outcomes. Complication and revision rates were also comparable. Circumferential reconstruction was associated with a significantly lower pooled rate of conversion to total hip arthroplasty (P = .01), but the nonrandomized evidence does not establish that the technique caused this difference.
Key findings
- The review included 1817 hips: 1086 treated with segmental and 731 with circumferential reconstruction.
- Both techniques improved all reported patient-reported outcomes, with no significant differences between groups (all P > .05).
- Complication rates and revision rates were comparable (P = .05 and P = .06, respectively).
- Circumferential reconstruction was associated with lower conversion to total hip arthroplasty (P = .01).
Why it matters
The findings suggest that both reconstruction approaches can improve pain and function, while the observed difference in conversion to total hip arthroplasty may be relevant when comparing outcomes. However, differences in study design and follow-up mean this association should not be interpreted as evidence that circumferential reconstruction prevents arthroplasty.
What to keep in mind
The evidence was heterogeneous and nonrandomized, with differences in follow-up duration between studies; causality cannot be inferred.
