BOPDHB Patient Resources Hip and Knee joint replacement book - June 2016 | Page 9

This section is not meant to frighten you, but help you to make
an informed decision on whether to have a total hip or knee
replacement, and to help you cope better with any complications
that may occur. It is important that you understand that there are
possible risks linked with any major operation. Total hip or knee
replacements are no exception.

Introduction

What complications (risks) can occur?

Total hip or knee replacement surgery is usually very successful but
a small percentage of patients may develop complications. Illness,
smoking and obesity may increase the chance for complications.
Though uncommon, when these complications occur, they may
delay or limit your full recovery.

Infection
An infection can occur in the wound or deep tissue around the
prosthesis. This could happen while you are in hospital, after you
go home and can even occur years later as any infection in your
body can spread to your joint replacement. Minor infections are
usually treated with antibiotics but major infections can sometimes
require surgery and removal of the prosthesis.

Dislocation
Occasionally after a total hip joint replacement the head of the
prosthesis can become dislodged from the socket. In most cases
the hip can be relocated without surgery. The period that you are
most at risk for dislocation is the first six weeks following surgery.

Blood clots, deep vein thrombosis (DVT)
This is the term used when a blood clot develops in the deep veins
in the back of your lower leg. When detected the treatment may
involve blood thinning injections followed by a course of tablets.
There is about a 4% risk of developing a DVT following surgery.
