EP4.2 Arthroscopic Repair of Acetabular Cartilage Delamination Using Chondral Nail Fixation in Femoroacetabular Impingement Patients
Hanmei Dong, Kang Tian, Guanying Gao, Rongge Liu, Siqi Zhang, Zhenlong Liu, Yan XuAbstract
Background: Acetabular cartilage delamination is commonly seen in Femoroacetabular impingement (FAI) patients, especially ones with the Cam deformity. However, the definition and classification of acetabular cartilage injuries caused by FAI are still remain controversial to guide clinical treatment. Moreover, treatment of acetabular cartilage damage always puts a surgeon into a dilemma situation during surgery. We believe a reliable repair of the acetabular cartilage delamination will lead to a better long-term outcome for FAI patients. Herein, we introduce the chondral nail fixation under hip arthroscopy for treating acetabular cartilage delamination in FAI patients. This technique contributes to eliminating intra-articular unstable factors, preserving native cartilage as much as possible, and restoring cartilage surface intact at best.

The definition, classification, and treatment of acetabular cartilage injury caused by FAI still remain controversial to guide clinical work. We believe a reliable repair of the acetabular cartilage delamination will lead to a better long-term outcome for FAI patients. Here, we introduce the absorbable chondral nail fixation under hip arthroscopy for treating acetabular cartilage delamination in FAI patients. This technique contributes to eliminating intra-articular unstable factors, preserving native cartilage as much as possible, and restoring cartilage surface intact at best. In this video, we will describe the surgical procedures of the chondral nail fixation technique in detail.
