Patient: Description of the disease (onset time, main symptoms, hospital, etc.): The patient is female, 52 years old, in July 9 in Zhejiang Second by Director Wu has done the left hip ceramic arthroplasty, now home recuperation. I am now recuperating at home. I am very grateful to Mr. Wu for his excellent medical skills and high medical ethics! My mother is now 45 days after the surgery and the wound is healing well, basically no other discomfort. The thread at the top of the wound is still there and occasionally rubs against her clothes and causes a bit of pain, will the thread disappear on its own after a while? In addition, compared to the right hip, the left hip is a bit protruding outward, which is a bit bigger than the right one, may I ask Dr. Wu what is the reason for this? Now I am walking with a walker a few times a day for about an hour, and the rest of the time I am basically lying on my back on the bed, doing occasional stirrups, leg bending and leg lifting exercises. Standing independently is not a problem, but when trying to walk independently the left leg will be more painful. Is my mother’s recovery normal? Does she need to do any more exercises? Can she do squatting exercises? Do I need to switch to crutches next? I have a lot of questions, so please give me a reply in your busy schedule, thank you very much! Wu Lidong, Department of Orthopaedics, The Second Affiliated Hospital of Zhejiang University School of Medicine: The threads need to be removed and will not disappear by themselves. You can come to the outpatient clinic to review the treatment of removal will not have discomfort. As long as the physical strength allows, as much as possible activities and exercise, double lower limb activities will have edema? It is better to walk with crutches now, as the bones will heal better. Other activities can be carried out according to the physical condition, squatting activities need to be carried out after three months. Wish your mom a smooth recovery! Patient: Thank you, Mr. Wu! I am glad to receive your reply so quickly! When there is a lot of movement, the ankle on the operated side will be slightly edematous, otherwise there is basically no discomfort. Currently, the left hip protrudes outward a bit compared to the right hip, a bit larger than the right side, and feels slightly harder than the right hip. The left knee also looks slightly higher than the right one, but there is no pain. In addition, when I move my right leg, I can occasionally hear a “popping” sound from the joint, but I can’t hear any noise from my left leg. Can you tell me what is wrong? Thank you very much! Wu Lidong, Department of Orthopaedics, The Second Affiliated Hospital of Zhejiang University School of Medicine: There may be a little bit, because the prosthesis is a standardized design and manufacture, while the individual has some specificity, so sometimes there will be a little different. But there shouldn’t be any problem. The right leg has not been opened, but there is definitely a problem, we recommend to come to the hospital to take a look. There are many reasons that can lead to joint rattling. Patient: Thank you, Mr. Wu. I will ask you to diagnose the problem when I go for a review. Wu Lidong, Department of Orthopedics, The Second Affiliated Hospital of Zhejiang University School of Medicine: I wish you a smooth recovery!
