For elderly patients joint replacement surgery is commonly required to treat damaged joints from wearing out, arthritis or other forms of joint disease including rheumatoid arthritis. In these procedures the damaged joint surface is removed and replaced with artificial surfaces normally made from metal (chromium cobalt alloy, titanium), plastic (high density polyethelene) or ceramic which act as alternate bearing surfaces for the damaged joint. These operations are major procedures which require the patient to be in hospital for several days and followed by a significant period of rehabilitation. The hospital has several ways of approaching the procedure for replacement and the specifics for the procedure will be covered at the time of assessment and booking of surgery. Occasionally blood transfusions are required; if you have some concerns raise this with your surgeon during consultation.

An incision (cut) is made on the side of the thigh to allow the surgeon access to the hip joint. The diseased and damaged parts of the hip joint are removed and replaced with smooth, artificial metal ‘ball’ and plastic ‘socket’ parts.

An incision (cut) is made on the front of the knee to allow the surgeon access to the knee joint. The damaged and painful areas of the thigh bone (femur) and lower leg bone (tibia), including the knee joint, are removed and replaced with metal and plastic parts.

This is a surgical procedure performed on a knee joint that has become painful and/or impaired because of disease, injury or wear and tear. In total knee replacement, artificial materials (metal and plastic) are used to replace the following damaged surfaces within the knee joint: the end of the thigh bone (femur) the end of the shin bone (tibia) the back of the kneecap (patella) This operation is a major procedure which requires you to be in hospital for several days and will be followed by a significant period of rehabilitation. Occasionally blood transfusions are required; if you have some concerns raise this with your surgeon during consultation. For more information about total knee replacement please click here.

Revision joint replacement is the repair or replacement of an existing joint replacement.

Otherwise known as degenerative arthritis. OA occurs when there is a breakdown of the cartilage, leaving the bones unprotected. It is very common and usually affects people as they get older. You can get it at any age and are more likely to if you have previously injured a joint, or are overweight. The symptoms can be very mild with just occasional pain with activity. Worsening symptoms include pain with activity and stiffness with rest. Joints can become swollen and restricted in movement. Joints can change shape as the bone changes in response to loss of protection. You otherwise feel well. The diagnosis is made on the basis of the history, examination findings and sometimes x-rays. The severity of joint damage seen on x-ray does not always correlate with the degree of pain you experience. Treatment includes guided exercises, weight reduction if needed, pain relief and sometimes surgery. For more information see www.arthritis.org.nz

Orthopaedic surgeons have expertise in the treatment of fractured (broken) bones, particularly in the assessment of damage that may have occurred around the fracture. Follow-up of a fracture may involve monitoring the progress of the healing bone, checking the position of the bone in a cast and deciding when other steps in management such as re-manipulation of the fracture or removal of a cast is required.
