During a hip replacement surgery, the soft tissues around the hip joint will have to be stretched to the proper tightness to ensure that the joint remains in position. This may result in the affected leg being slightly longer than the other. However, some people don’t really notice it as the extension is only a few millimeters.
When the lengthening of the leg which was operated upon is more than 1.5cm, it is considered to be unacceptable and can be a strong ground to make a claim.
