Purpose
The purpose of this study was to determine if conversion to total hip arthroplasty and patient-reported outcomes were similar in the first 100 patients who underwent segmental labral reconstruction with iliotibial band autograft compared to the most recent 100 patients.
Methods
Patients who underwent hip segmental labral reconstruction with autologous iliotibial band were evaluated preoperatively and postoperatively with a minimum 2-year follow-up. The first consecutive 100 patients (Group 1) and the most recent 100 patients (Group 2) were retrospectively compared. Conversion to total hip arthroplasty, necessity of a revision hip arthroscopy, and patient-reported outcome scores were compared.
Results
Overall follow-up rate (> 2 years) was 94% (Group 1 vs. Group 2, 91% vs. 96%, n.s.). Mean age of Group 1 (37 ± 12) was significantly higher than that of Group 2 (34 ± 12) (p = 0.03). In Group 2, 69 surgeries out of 100 were revision hip arthroscopies, which was significantly higher rate than Group 1 (48/100) (p = 0.003). Group 1 had significantly higher rate of conversion to THA [23% (23/100) vs. 5% (5/100), p = 0.001]. Revision hip arthroscopy was performed in 11/76 (15%) in Group 1 and in 8/95 (9%) in Group 2 (n.s.). Patient-reported outcomes scores were similar between two groups (all n.s.). Higher age and joint space ≤ 2 mm were significant risk factors of total hip arthroplasty conversion.
Conclusion
This study showed that, with experience, fewer conversions to total hip arthroplasty were seen; however, revision rate and outcomes were similar.
