Arthroscopic hip labralization significantly improved the Non-Arthritic Hip Score by a mean of 38 points (from 52 to 90, p=0.031) in patients with cam-pincer femoroacetabular impingement.
Arthroscopic hip labralization is presented as a relatively simple, graft-free alternative to labral reconstruction that may restore fluid seal function.

May support graft-free labralization in cam-pincer FAI; hypothesis-generating and should not yet change practice.
Labralization, which may be performed by open or arthroscopic means, may be an attractive alternative to hip labral reconstruction. By preserving the articular cartilage in the region of labral deficit with meticulous rim trimming, the resultant undermined free chondral margin ("pseudolabrum") may immediately restore a fluid seal function and may theoretically enhance hip preservation. Arthroscopic hip labralization is a relatively simple and fast procedure without graft harvest morbidity. It may be performed in patients tolerating rim reduction with encouraging preliminary outcomes.

Dean K. Matsuda (2014) studied Cam-pincer femoroacetabular impingement (n=6). Arthroscopic hip labralization vs. Preoperative baseline was evaluated on Non-Arthritic Hip Score (mean improvement of 38, p=0.031). Arthroscopic hip labralization significantly improved the Non-Arthritic Hip Score by a mean of 38 points (from 52 to 90, p=0.031) in patients with cam-pincer femoroacetabular impingement.
