ABSTRACT
Purpose
To evaluate the safety of hip arthroscopy combined with a periacetabular osteotomy (PAO) compared with PAO alone in treating concomitant intra-articular pathology in hip dysplasia.
Materials and methods
Forty-one patients (46 hips) with symptomatic hip dysplasia were retrospectively reviewed. Pre- and postoperative radiographic data and intraoperative data consisting of estimated blood loss, intraoperative and postoperative blood transfusions, operative time, and length of hospital stay were recorded. The complications occurring within the first 3 months after surgery including lateral femoral cutaneous and pudendal nerve neuropraxia, wound complications, and reoperations were recorded. Additionally, rates of deep venous thrombosis and other major adverse outcomes (myocardial infarction, pulmonary embolism, stroke, death) were examined.
Results
Twenty-one patients (24 hips) underwent PAO alone. Twenty patients (22 hips) underwent hip arthroscopy followed immediately by PAO. There were no significant differences in the 90-day complication rates between the two groups, comparing the rate of neuropraxia (p = 0.155) and wound complications (p = 0.6). Operative time for PAO alone was 179 minutes (standard deviation [SD] ± 37) compared with 251 minutes (SD ± 52) for combined hip arthroscopy and PAO (p < 0.001). No incidence of deep vein thrombosis or major adverse events was noted in either group. Preoperative lateral center edge angle (LCEA) and acetabular index (AI) were 14° and 20° respectively, in the PAO-alone group and 19° and 16° respectively, in the combined group. Postoperatively, LCEA was 29° in the PAO-alone group and 30° in the combined group. Postoperative AI was 11° in the PAO-alone group and 5° in the combined group.
Conclusion
This study demonstrates that hip arthroscopy in combination with PAO to treat intra-articular pathology shows no difference in 90-day complication rates when compared with PAO alone.
