Increased rate of hysterectomy in women undergoing surgery for osteoarthritis of the knee.
We performed a case-controlled study to determine whether previous gynecological surgery is associated with severe osteoarthritis (OA) of the knee, the hip or the spine, as well as mild OA of the knee. Patients who underwent surgical treatment for OA were defined as having severe OA. Patients with knee pain and radiographic grade 2 OA in a tibiofemoral joint on the Kellgren and Lawrence scale were defined as having mild knee OA. An increased rate of hysterectomy was observed in the severe knee OA group after adjustment for age and number of children, or even after adjustment for body mass index. Hysterectomy in this group was most often performed for myoma uteri. Patients with mild knee OA tended to have previous hysterectomy. From the results, we speculate that certain subsets of OA which often take a progressive course might be related to hysterectomy.
