Improved hip replacement consists in the insertion of a replacement rod into the femoral condyle. This gives the pelvic bone access to the acetabular cup supporting the condyle through an improved hip replacement implant based on its rotation using ball joints and a bone attachment system； and using a screw spike inserted in the femur and fixing it to the rectangular face bushing on the outer surface of said bone to which the condyle is also rigidly joined. The condyle is inserted in a round configuration consisting of the round shell in contact with the pelvic bone and the threaded sealing lid, the place where the ball joints that guarantee rotation between said bones are located. Finally, said round shell in contact with the pelvic bone is completed with filaments for securing it to said bone.
