sides of joint : Total refers to both sides of the hip joint - are replaced often metal on one side (the ball) and a special plastic on the other side the cup. Partial is where only one side is replaced usually the ball.

Different: A half a hip replacement is called a hemi arthroplasty. It is typically used for fractures and replaces only the ball at the top of the femur. The hip socket is native. In a total hip replacement both the ball and the socket are replaced.

THA vs partial: Total hip replaces both the femoral and acetabular sides with specific-sized implants. A partial hip typically replaces only a part of it, or may refer to resurfacing procedures.
