Study reveals risk factors for hip replacement revision surgery

Published on 18 December 2012

A study has shed light on factors that increase the risk of needing revision surgery following an initial hip replacement procedure.

Results show that patients who were aged 75 or under at the time of their initial surgery were more likely to need revision surgery than those who were older.

Taller patients were also more likely to need revision surgery, as were those with a high body weight.

Other risk factors for revision surgery appear to be a history of prior orthopaedic surgery and use of a cemented femoral component.

Scientists at Brigham and Women’s Hospital and Harvard Medical School in the US looked at data on patients who had a hip replaced between July 1995 and June 1996, each of whom was matched with a control patient.

In total, they looked at 719 pairs of patients, as well as their hospital records in order to observe any potential risk factors.

Publishing their findings in the journal Arthritis Care & Research, the study authors claimed that their research is the first such US study to look for risk factors for hip replacement revision surgery.

They concluded that “younger, taller and heavier patients, and those receiving a cemented femoral component, had a greater likelihood of undergoing a revision total hip replacement over a 12-year follow-up period”.

“Effects of age and body size on revision risk should be addressed by clinicians with patients considering primary total hip replacement,” they added.

A spokeswoman for Arthritis Research UK commented that the number of hip revision operations was increasing and, when performed by specialist surgeons, could give reliably excellent results, despite a slightly higher risk of complications than in first-time hip replacement surgery.
