Excerpt
Pincer-type femoroacetabular impingement (FAI) is defined as either a focal or global overcoverage of the femoral head by the acetabulum [
2]. This pathoanatomy is thought to cause impingement and injury to the acetabular labrum, resulting in secondary injury to the articular cartilage and in some patients, osteoarthritis (OA) [
4]. On the other end of the spectrum is acetabular dysplasia, where the femoral head is undercovered by the acetabulum leading to a decrease in the amount of weight bearing articular cartilage. Subsequently, increased forces across the joint can, in some patients, lead to OA [
