Hip osteoarthritis is a degenerative joint condition characterized by the breakdown of cartilage in the hip joint, leading to pain, stiffness, and reduced mobility. It can be caused by aging, genetics, joint injuries, or excessive wear and tear. Symptoms may include pain in the hip or groin, limited range of motion, and difficulty with activities such as walking or climbing stairs. Treatment options include pain management, physical therapy, lifestyle modifications, and in severe cases, hip replacement surgery. Seeking medical evaluation is crucial for proper management of hip osteoarthritis.
