Purpose: We researched this topic with the main purpose of determining and analyzing the causes of failure after hip arthroplasty (HA) consist of the prevalence of injuries, clinical characteristics and the reasons of damage to the artificial joint, requiring revision surgery. Thereby evaluating the initial results after hip revision surgery according to the corresponding damage.
Materials and methods: Retrospectively describe and analyze 98 cases of joint revision surgery, performed at Quy Hoa Hospital, from 2014 to 2023. We reviewed each patient's data stored by the surgeon and in the recorded medical records including clinical and radiological features, operative reports, and reasons for the patient's visit, the cause of the injury led to the decision to re-operate. Results of the surgery were evaluated according to the Modified Harris Hip Score. The longest follow-up time after Revision surgery is 6 years, the shortest is 1 year. All data were analyzed, processed using software SPSS 20.0.
Results: 51.8% were aseptic stem-loosening, of which 21.6% were early loosening after HA due to technical errors and 30.2% were late stem-loosening due to osteoporosis in the elderly. 14.2% is cemented periprosthetic osteolysis over 10 years, 10.3% is deep infection and 9.3% is instability-dislocation. Instability- dislocation is the reason for early surgery for the patient. All revision surgeries for stem loosening were cementless and Wagner's long stem had good results. The overall result of good or better is 88.5%.
Conclude: Failure after HA/THA is increasingly common and needs to be carefully researched to come up with the best strategy, which is the key to success in the very difficult surgical decision. It also provides a partial picture of the frequency of causes of failure after primary HA, as a basis for indications for re-operation, and some valuable experience in techniques to get the next step results.
