Peripheral versus central compartment starting point in hip arthroscopy for femoroacetabular impingement.

The purpose of this study was to compare the perioperative complications and traction times in femoroacetabular impingement hip arthroscopy with either a peripheral or central compartment starting point. Sixty patients with femoroacetabular impingement were treated with hip arthroscopy. Thirty patients had a peripheral compartment starting point and 30 had a central compartment starting point. Intra- and postoperative complications were documented along with traction times. The peripheral compartment starting group experienced 6 minor chondral injuries and 1 case of postoperative paresthesias. The central compartment starting group experienced 8 minor and 3 moderate chondral injuries, 2 labral penetrations, and 3 cases of postoperative paresthesias. Traction time averaged 46 minutes in the peripheral compartment starting group and 73 minutes in the central compartment starting group. Iatrogenic injury and traction times are decreased with peripheral vs central compartment starting in hip arthroscopy for femoroacetabular impingement. Consideration should be given for peripheral compartment starting in hip arthroscopy for the treatment of femoroacetabular impingement.
