Abstract
Purpose: to evaluate the effectiveness of a differentiated approach to early rehabilitation of elderly patients after hip arthroplasty based on the Charlson Comorbidity Index compared to standard rehabilitation programs.
Material and methods: the study included 120 patients aged 35 to 75 years who underwent hip arthroplasty between 2020 and 2024. Patients were divided into a study group (individualized program considering comorbidity index and innovative technologies) and a control group (standard program). Effectiveness was assessed using the EQ-5D-5L quality of life questionnaire and a visual analog scale for general health at three time points: baseline, one month, and six months after program completion. Statistical analysis used Student’s t-test, Mann-Whitney U test, χ² test, and Pearson correlation analysis at a significance level of p < 0.05.
Results: baseline indicators were comparable between groups (VAS: 40.18 points in control, 43.07 in study group). After one month, more pronounced positive dynamics were observed in the study group across all EQ-5D-5L domains. After six months, the overall health score in the study group reached 80.23 points compared to 75.25 points in the control group (difference 4.98 points). Pain and discomfort decreased to 1.32 points versus 1.62 points in the control group.
Conclusion: a differentiated rehabilitation approach based on comorbidity index and innovative technologies provides statistically significant and sustained improvement in functional outcomes and quality of life in elderly patients after hip arthroplasty compared to standard programs.
