Q: A year ago, I underwent a hip resurfacing procedure. However, for some time now, the prosthesis has begun to make strange noises.  What might be causing this? 


A: these noises are usually linked to the hard joint mechanics that are in constant contact with one another, in turn generating noise (we speak of the metal to metal coupling in the case of prostheses coating). Proper exercises for muscle toning should strengthen the gluteus medius and gluteus minimus, in turn resolving the issue of “strange noises”.
