Abstract:

Objective

To analyze the main causess for hip revision in patients who have primary total hip replacement(THA) under 40 years old, and to compare with the elderly (age≥60 years).

Methods

A retrospective analysis was conducted on 156 patients (76 in the young group and 80 in the elderly group) who underwent revision hip arthroplasty at Nanchang Hongdu Hospital of Traditional Chinese Medicine from January 2005 to October 2020. Clinical data of 188 hip joints (102 hips in the young group and 86 hips in the elderly group) were collected to clarify the reasons for hip revision, the time between two operations, and the difference in the revision part. Chi-square test was applied to analyze the relationship between revision parts and the fixation methods of primary THA (bone cement or cementless prostheses).

Results

The average interval between primary THA and revision surgery in the young group was(11±5)years. The most common causes of primary THA were: avascular necrosis of the femoral head, developmental dysplasia of the hip, traumatic arthritis and juvenile idiopathic arthritis. The causes for hip revision in the young group were: acetabular prosthesis loosening(29.4%), polyethylene liner wear(20.6%)and femoral prosthesis loosening(18.6%). The most common reasons for revision in the elderly group were: postoperative dislocation(26.7%), infection(20.9%), and loosening of the acetabular prosthesis(16.3%). In the young group, the revision part of prosthesis was not related to the fixation method in primary THA (χ2=0.146, P>0.05).

Conclusions

After primary THA, acetabular prosthesis loosening, polyethylene wear and femoral prosthesis loosening are the common causes of revision in young patients; while the incidences of postoperative dislocation and infection are lower in the youth than that in the elderly.
