Loose bodies like bone chips (broken bones) or torn cartilage debris can remain or float in the joint space. These pieces can be caught in the hip during movement.
Characteristics of loose bodies in the knee joint:
Cause: Fractures OR trauma OR articular cartilage injuries OR loose bodies may remain in the joint after some closed treatment procedures of hip dislocations or due to wall fractures.
Symptoms: Hip pain, feeling of hip locked or struck and decreased range of motion.
Treatment: Knee arthroscopy is recommended to remove these loose bodies without completely opening the knee joint.
