Osteoarthritis causes pain, limitation of range of motion, and gait disturbance due to degeneration of the articular cartilage. Osteoarthritis is one of the most common disease and about ten milion patients suffer from this condition in Japan. Japanese patients are associated with developmental dysplasia of the hip and acetabular dysplasia. Pathogenesis of hip pain remains unclear about sensory innervation and pain transmission. Hip pain also tends to resist to pain killar. While total hip arthroplasty is effective treatment, revision surgery will be necessary because of the implant loosening. Thus, solution of pain mechanism in osteoarthritis of the hip is needed.
The purpose of this study is to clarify the pathogenesis of hip patin. Basic research evaluates sensory innervation and pain transmitter of human hip joint using immunohistchemistry. Clinical research evaluates destribution of hip pain and referred pain.

In basic research, synovium, limbus, femoral head and acetabulum are stained with neuron-specific class III beta-tubulin (TuJ-1), isolectin B4 (IB4), calcitonin gene-related peptide (CGRP), transient receptor potential (TRP), tromyosin receptor kinase (Trk), tumor necrosis factor-alpha (TNFa), nuclear factor-kappa B (NFkB), and p55TNF receptor. Qualitative and quantitative assessments are performed between osteoarthritis and femoral neck fracture.
In clinical research, distribution and incidence of hip pain are evaluated as well as referred pain. Association of hip pain, immunohistchemistry, and image findings are analyzed.
