| Abstract: | [Purpose] The aim of this study was to examine the incidence and patterns of referredpain in patients with hip disease, as well as the nerve distribution in the hip and kneejoints of 2 cadavers. [Subjects and Methods] A total of 113 patients with hip jointdisease were included in the investigation. The incidence of regional pain and referredpain patterns were evaluated before and after arthroplasty. Two cadavers weremacroscopically observed to verify the nerve innervation of the hip and knee joints.[Results] Anterior knee pain was observed preoperatively in 13.3% (in resting) and 33.6%(in motion) of the patients, which was comparable with the incidence of greater trochanterpain. In addition, the preoperative incidence rates of knee pain in resting and motionmarkedly decreased postoperatively. Of note is the remarkable incidence of pain radiatingto the ventral lower limb. An anteromedial innervation was determined in the cadavers bythe articular branches of the obturator and femoral nerve, which supply small branches tothe knee joints. [Conclusion] Our results suggest that the distribution of the incidenceof pain among the patients with hip disease is diverse owing to the sensory distributionof the femoral and obturator nerves.Key words: Hip joint disease, Referred pain, Macroscopic anatomy |
