Accurately identifying the source of pain is crucial for diagnosing hip osteoarthritis. Many individuals affected by this condition seek orthopedic consultation for knee pain, despite its origin being the hip. Pain associated with hip osteoarthritis often radiates to the knee, which can delay diagnosis. Pain in the hip region can also stem from other causes such as bone necrosis, soft tissue diseases, and lower back problems; however, these pains are generally not related to osteoarthritis. While osteoarthritis-related pain typically manifests in the front of the groin, most pain in the back of the hip originates from the lower back.
