Sir,
At this age, the problem seems to be really big. From the data you have given, i think we are missing a bigger picture. Need more data and evaluation. At the outset, i think the solution seems to be bilateral THR ....but personally i have delt many such cases with out surgery.
Next Steps
please get an opinion from a well expiriened Orthopaedic surgeon. If replacement is the only choice, then consider Resurfacing proceedures like Birmingham hip
Health Tips
Please please please do not jump for surgery.
