Symptoms of hip joint effusion vary at different times, with pain and swelling in the early stages, muscle atrophy as the disease progresses, and bone spurs and even osteophytes in the later stages. In the early stage of the disease, patients will experience joint pain or with mild swelling, feel creaking at the knee when walking, and experience joint pain or discomfort when walking up stairs or applying force. As the disease progresses, there will be discomfort when squatting or bending, and some patients will experience muscle atrophy and severe swelling after excessive exercise. Symptoms are usually mild in the morning and worse at night. In the later stages of the disease, the joints are heavily swollen and pain is unusually pronounced, accompanied by fluid accumulation and bone spurs. Some patients may develop osteophytes and experience severe pain when walking up and down stairs, affecting their normal life. If the above related symptoms occur, it is recommended to consult a doctor in time for treatment in order to minimize the adverse effects of the disease.
