Advances in Hip Arthroscopy
Published in K. Mohan Iyer, Hip Joint in Adults: Advances and Developments, 2018
Hip arthroscopy is now routinely used to deal with acetabular labral tears, femoroacetabular impingement (FAI), chondral injuries, loose bodies, joint infection, capsular laxity and injuries to the ligamentum teres. Extra-articular conditions and other less common indications for hip arthroscopy include management of internal and external snapping hip, synovial chondromatosis and other synovial abnormalities, crystalline hip arthropathy (gout and pseudo gout), management of posttraumatic intra-articular debris, osteonecrosis of the femoral head, management of mild to moderate hip osteoarthritis with mechanical symptoms and as an adjunct diagnostic and therapeutic tool in conjunction with open femoral and/or periacetabular osteotomy for dysplasia and complex hip deformities. With advances in techniques, reconstruction of the ligamentum teres, capsulorrhaphy in cases of instability and repair of injuries to the gluteal tendons are being studied. Occasionally, patients with longstanding, unresolved hip joint pain and positive physical findings may benefit from arthroscopic hip assessment [1,2].

Characterised by an aspherical femoral head or head–neck junction with a reduced offset, a cam deformity may induce femoroacetabular impingement (FAI) between the proximal femur and the hip socket during extreme limits of hip motion (Ganz et al. 2003; Siebenrock et al. 2004). This mechanical impingement results in higher joint stresses (Chegini et al. 2009; Ng et al. 2012; Speirs et al. 2013a), putting the articulating cartilage at a greater risk of developing degenerative changes (Agricola et al. 2012; Beaulé et al. 2005; Ganz et al. 2003; Speirs et al. 2013a). Clinical symptoms associated with cam-type FAI typically include motion-induced pain, reduced hip flexion and sagittal range of motion (Allen et al. 2009; Kappe et al. 2012; Lamontagne et al. 2009).
