The Effect of Previous Hip Surgery on the Outcome of Hip Arthroplasty in Young Patients

Background

The incidence of total hip arthroplasty (THA) is increasing in all age groups, especially in young patients. The outcome of THA is believed to be affected by morphological deformities created by previous pelvic or femoral procedures performed in childhood. The aim of the present study was to assess whether previous hip surgery impaired the functional outcome in young patients who underwent THA.

Methods

Data were collected from the records of patients aged less than 30 years who had undergone THA between 2002 and 2011. Thirty-five patients (44 hips) were included. The Western Ontario and McMaster Universities Osteoarthritis Index and Harris Hip Scores were collected as primary functional outcome measures. The secondary outcome measures were the major and minor complications. Patients were divided into 2 groups: those who had not undergone hip surgery before THA (group I, 17 patients, 24 hips) and those with a history of prior hip surgery (group II, 18 patients, 20 hips).

Results

The mean age at the time of surgery was 25 ± 4 years in group I and 23 ± 4 years in group II. The mean Harris Hip Score was slightly higher in group I (90 ± 7) than in group II (87 ± 7) (P = .2). The mean Western Ontario and McMaster Universities Osteoarthritis Index scores were similar in both groups (in group I 14 ± 7 and in group II 14 ± 6, P = .9). Complication rates were also similar in both groups (P = .7).

Conclusions

It is often difficult to decide whether to perform THA in young patients. One potential risk factor for complications is hip surgery before THA. Our study revealed that young patients with or without a history of previous hip surgery achieved satisfactory functional outcomes with similar complication rates after THA.
