The aim of this review is to evaluate the current
available literature evidencing on peri-articular hip endoscopy
(the third compartment). A comprehensive approach has been set on
reports dealing with endoscopic surgery for recalcitrant trochanteric
bursitis, snapping hip (or coxa-saltans; external and internal),
gluteus medius and minimus tears and endoscopy (or arthroscopy)
after total hip arthroplasty. This information can be used to trigger
further research, innovation and education in extra-articular hip
endoscopy.
