A sudden (acute) injury may occur from a fall on the hip, a direct
blow to the hip or knee, or abnormal twisting or bending of the leg. Examples
of acute injuries that may cause a snap, pop, or grating sound or feeling
include a broken hip (hip fracture) or pelvis (pelvic fracture),
muscle strain in the groin or buttock, or severe
A condition known as iliotibial band syndrome is a painless snap,
pop, or grating sensation heard or felt in the hip joint when you sit or squat
(not at the time of an injury). The snapping sensation occurs when a tendon
moves over a bony point of the hip, pelvis, or upper thighbone (greater
trochanter). You may not have hip pain or you may have only mild tenderness.
Knee pain, a decreased ability to move the hip, and leg weakness may also be
present. Iliotibial band syndrome usually affects people ages 15 to 40 and is a
common problem in ballet dancers, athletes (such as distance runners), or
people who do similar hip movement exercises.
A acetabular labrum tear can cause a wide variety of symptoms. Some people don't have any discomfort. Others have sharp pain around the groin, which may extend into the upper leg or buttocks. Pain can come on suddenly or develop gradually. Rotating your leg may be particularly painful.
Acetabular labral tears often cause a feeling of the leg "catching" or "clicking" in the hip socket as you move it. It may also feel like the leg is locking up.
Over time, the increased stress on the joint could...

after surgery to replace the hip (a total hip replacement).
Treatment depends on the location, type and severity of the injury as
well as your age, general health, and activities (such as work, sports, and
hobbies). Treatment may include first aid measures; application of a brace,
cast, harness, or traction; physical therapy; medication; or surgery.
