Abstract

Summary: The purpose of this study was to document the incidence of intra-articular pathology found arthroscopically before PAO was performed.

Objective:
Periacetabular osteotomy (PAO) has a proven track record in the treatment of acetabular dysplasia. However, poor results are associated with coexistent intra-articular pathology. The purpose of this study was to document the incidence of intra-articular pathology found arthroscopically before PAO was performed.

Methods:
Between October 2010 and May 2011, seven patients with acetabular dysplasia underwent PAO with a concomitant hip arthroscopy at our institution. All patients had mild dysplasia with a center edge angle <20 degrees (range, 9 to 18 degrees). Intra-operative findings including the labrum, chondral surface, ligamentum teres, and psoas tendon were recorded.

Results:
The mean age of the patients at the time of surgery was 24 years old (range, 12 to 33 years). All patients had arthroscopic evidence of intra-articular pathology which required surgical intervention. An anterosuperior labral tear was found in all patients, 5 of which required labral repairs, the other two underwent selective debridement. Two patients had a full-grade ligamentum teres tear, and the remaining 5 had partial thickness tears; all were debrided. Six patients had chondral injury; 5 had a chondroplasty, and 1 had microfracture as well. Two patients had evidence of internal snapping, and had a functional psoas tendon lengthening. Two patients with femoral cam-type lesions had a concomitant arthroscopic femoral osteoplasty.

Conclusion:
Intra-articular pathology in the presence of acetabular dysplasia was found in all seven patients. Therefore, we recommend performing a concomitant hip arthroscopy before the PAO surgery to address that pathology in an effort to decrease the failure rate.
