Raloxifene Retards Cartilage Degradation and Improves Subchondral Bone Micro-architecture in Ovariectomized Rats with Patella Baja-Induced- Patellofemoral Joint Osteoarthritis.
Abstract
Abnormal remodeling of subchondral bone (SB) induced by estrogen deficiency has been shown to be involved in osteoarthritis (OA). Raloxifene (RAL) is commonly used to treat postmenopausal osteoporosis (OP). However, little is known about its effects on OA combined with estrogen deficiency. This study was performed to evaluate the efficacy of RAL on patella baja-induced patellofemoral joint OA (PFJOA) in an ovariectomized rat model.
