Hip & knee replacement

A total knee replacement showing a diseased joint, with the bones then cut and shaped, and the implants and metal in place to reform the kneeDuring a joint replacement operation (also called arthroplasty) some, or all, of a damaged or diseased joint is replaced with an artificial one. It is usually done when a joint has become very painful, is causing disability, and can no longer be managed with nonsurgical treatments. Hips and knees are the most common joints to be replaced.

The NHS Choices website has good sections explaining hip replacement and knee replacement.

Will I get publicly funded joint replacement?

Four steps of a hip replacement. Diseased bone is cut out. Metal ball joint is inserted into femur and metal socket is put in hip bone. The two are then brought together to reform the joint.Canterbury DHB's Orthopaedics Department faces a huge demand for joint replacement surgery. Because of this, GPs will only refer people who are suitable for surgery, and have tried all nonsurgical treatment options. Your GP will make sure you try all treatment steps before considering referring you to the Orthopaedics Department.

If you want surgery before it is available through the public system, talk to your GP about being referred to a private orthopaedic surgeon.

Many people with arthritis can manage well by making lifestyle changes and using nonsurgical treatment, and will never need surgery.

 

After a hip or knee replacement

The ERAS booklets on Preparing for hip & knee replacement surgery have information about what to expect after a hip or knee replacement.

Your surgeon will normally see you again four to six weeks after your hip or knee replacement. By then, you should have been able to resume most of your normal daily activities including walking without a walker or crutches, and showering. If you drive, you may be back driving. If you work, you should be able to return to work.

Talk to your GP or physiotherapist if you are still having problems with daily activities, or if you want to want to restart a strenuous activity or sport. It might help if they design a specific exercise programme for you.
