Associated Intraarticular Injuries

The most common associated lesions with labral tears in athletes are chondral injuries [2]. These injuries are usually adjacent to the labral pathology [2,11,12]. Chondral changes include chondromalacia, thinning of the cartilage, delamina-tion of the cartilage, chondral flap tears (Fig. 10), and full-thickness chondral

injury with exposed bone (Fig. 11). Lateral impaction injuries seen with football injuries have been reported [16].

Ligamentum teres in conjunction with labral tears has been reported [11]. The ligamentum teres is attached from the acetabular fossa to the fovea capitus and has both anterior and posterior bundles. Partial ligamentum teres tears (Fig. 12) have been described by Rao and colleagues [17]. This ligament tightens in external rotation, and may have a secondary stabilizer role with labral deficiency [17]. Displaced ligamentum teres tears can cause impingement with hip flexion (Fig. 13).

Synovitis can occur with labral tears in athletes. Capsular inflammation can be visualized adjacent to the labral tear (Fig. 14).

Potential loose bodies, particularly in known traumatic injuries, should be evaluated in both the central and peripheral compartments (Fig. 15) [11,18]. The

presence of multiple loose bodies, however, should be considered for synovial chondromatosis [19].
