COMPARATIVE CLINICAL-BIOMECHANICAL EFFICACY OF PERSONALIZED VERSUS STANDARD REHABILITATION PROGRAMS AND PROGNOSTIC BIOMECHANICAL MARKERS OF LONG-TERM OUTCOMES AFTER PRIMARY TOTAL HIP ARTHROPLASTY

Resume. This article examines the comparative clinical-biomechanical efficacy of personalized versus standard medical rehabilitation programs after primary total hip arthroplasty (THA), together with prognostic biomechanical markers of long-term functional outcomes. A prospective controlled study included 230 patients (main group, n=122; control group, n=108). At 12 months, the Harris Hip Score was 95.77–96.44 points in the main group versus 86.32–86.46 points in the control group (p<0.01), and the SF-36 physical component was 52.7±6.4 versus 44.3±7.1 points (p<0.001). Correlation analysis revealed a strong inverse relationship between preoperative load asymmetry coefficient (Ka) and the 12-month physical component of quality of life (r=–0.68; p<0.001), and high predictive value of the 3-month Ka for 12-month outcomes (r=0.72; p<0.001). These findings confirm the high prognostic value of baseline biomechanical indices for early stratification of patients by rehabilitation potential.
