The effect of a biologic-enriched preparation on the clinical outcomes of patients with femoroacetabular impingement after arthroscopic repair of the acetabular labrum and osteoplasty

A recent study published in the journal The Journal of Hip Preservation Surgery compared the clinical outcome in patients in whom a biologic-enriched preparation was given by intra-articular injection during arthroscopic repair of the labrum of the acetabulum and osteoplasty of the femoral neck for femoroacetabular impingement. Patients were randomised during surgery to receive either an injection of 5 cc of biologic agents or an equal volume of 0.9% normal saline. All patients underwent arthroscopic repair of the acetabular labrum and osteoplasty of the femoral neck, and received the injection at the end of the arthroscopy.
Patients were assessed using the hip outcome scales Non Arthritic Hip Score, Modified Harris Hip Score and Hip Outcome Score, which were measured before surgery and then at one, three, six and 12 months postoperatively. A total of 35 patients were included in the study. 12 patients received an injection of biologic agents, while 15 received an injection of normal saline.
The authors observed that there was no statistically significant difference in any of the outcome scores between the two groups. They therefore concluded that an intra-articular injection of biologic agents after arthroscopic repair of the acetabular labrum does not improve the clinical outcome up to one year postoperatively.
