Hip dysplasia is a genetic condition that affects the hip joint, where the ball and socket do not fit together properly. This misalignment can lead to joint instability, pain, and eventually arthritis. It is most commonly seen in large dog breeds, but it can also occur in humans and other animals. Symptoms of hip dysplasia may include limping, difficulty rising, or reluctance to exercise. Diagnosis typically involves a physical examination and X-rays to assess the joint's structure. Treatment options range from weight management and physical therapy to surgical interventions, depending on the severity of the condition.
