Clinical and functional results of revision arthroplasty A 2 year single-center observational study.
Main Article Content
Abstract
Introduction: Hip and knee arthroplasty revision surgery are rescue procedures in patients with infections or mechanical loosening of the prosthesis. The objective of this study was to evaluate the functional results after revision surgery over two years, applying the respective functionality scales.
Methods: The present observational study was conducted at Hospital Alcívar in Guayaquil, Ecuador, from January 2021 to December 2022 with patients undergoing shoulder and knee arthroplasty revision surgery. The variables were age, sex, time of onset of symptoms, presence of joint instability, and pain rating scale (VAS) before and after surgery. Joint mobility and postoperative functional scale.
Results: The study included 23 patients. In 17 cases (73.9%), knee prostheses were revised; in 6 cases (25.1%), hip prostheses were revised. There were 15 men (65.21%) and eight women (34.79%), with an average age of 67 years. The cause of prosthesis change was mechanical in 15 cases (65.21%) and infections in 8 patients (34.78%). Joint instability occurred in 17 cases (73.91%) and without instability in 6 cases (23.08%). Pain decreased from severe perception in 18 patients (78.3%) in the preoperative period to mild in 18 cases (78.3%). Knee functionality at three months was good in 7 cases (41.2%); at six months, it was good and excellent in 9 patients (52.9%). Hip functionality was regular at three months in 5 cases (83.3%) and good at six months in 5 cases (83.3%).
Conclusions: Overall, the results of this study suggest that revision arthroplasties are an effective procedure to improve the functionality of patients with aseptic loosening and septic failure of knee and hip replacements.
