Hello,
Thank you for your query at DoctorSpring.com
I understand your concern.
Can you kindly upload a high resolution picture of his leg for me to review? Also can you give me a detailed medical history? When was the hip replacement done? Does he have any history of hypertension or diabetes?What about his serum electrolytes?
Yes metal hip replacement does have a lot of side effects, because in certain cases due to constant friction, small metal particles are broken and get released in the blood stream leading to metallosis. It is not very common, however possible. Mostly the surrounding area will have a lot of infection, there are chances of osteolysis, local soft tissue destruction, deterioration of bone around the implants, severe joint pain. Though it's not a common feature to have such swelling of the legs, however it is better you get your physician to run a series of x rays to check if the implant is in proper order. A simple x ray will be able to detect if there is any surrounding destruction.
Regards.
