Hip pain may develop secondary to reduced space between the femoral ball and acetabular socket. This can be a part of Primary OsteoArthritis, or sometimes develop secondary to Hip fractures, Avascular Necrosis of Hip, Hip dysplasia, Coxa Magna, Perthes disease etc.
Typically, patients with early Hip Arthritis present with anterior groin pain, that is most pronounced on sitting on the floor, or getting up from standing position.
With progressive damage, patients often report pain in the hip region referred along the knee. On clinical evaluation, such cases are found to have limitation in Abduction and Internal rotation movements with the hip joint in flexion. The earliest sign could also be loss of hip extension.
