Hip dysplasia is a congenital condition in which the acetabulum or socket is shallow. This creates under-coverage of the femoral head. The weight-bearing portion of the hip becomes overloaded as it is increasingly focused on a small area.
Dysplasia can lead to hip instability, labral damage and early-onset arthritis.
Patients with untreated dysplasia may be at an increased requirement of a hip replacement early in life.
Mild dysplasia can often be addressed arthroscopically by repairing a torn labrum and tightening the capsule around the joint.
Severe dysplasia can be treated with correction of the mechanical and bony deformity through a procedure called a peri-acetabular osteotomy (PAO). The American Hip Institute has created a team to severe dysplasia with combined arthroscopy, to repair torn labrum arthroscopically, and a PAO, to correct the bony mechanical deformity, in the same operation. This is aimed to treat both the bony deformity and the source of pain.
