| This prospective observational study aims to evaluate how preoperative frailty affects postoperative outcomes in elderly patients undergoing Total Knee Arthroplasty (TKA). Frailty is a clinical syndrome characterized by reduced physiological reserve and increased vulnerability to stress, and it is considered an independent predictor of surgical risk.
Rationale Although TKA is effective for severe knee osteoarthritis, many elderly candidates are frail. Frail patients tend to have: • Higher rates of postoperative complications • Delayed recovery and prolonged hospital stay • Increased need for post-discharge rehabilitation facilities
However, frailty assessment is not routinely done in preoperative evaluation. This study intends to bridge this gap.
Study Objectives Primary Objectives: 1. Assess preoperative frailty in patients scheduled for TKA. 2. Analyze postoperative complications and recovery patterns.
Secondary Objective: • Determine the relationship between frailty level and length of hospital stay.
Methodology • Study Setting: Three hospitals under Kasturba Medical College, Mangalore. • Participants: Patients aged 60–85 years, ASA Grade I–III, undergoing TKA. • Sample Size: 83 participants determined based on prevalence data. • Study Tool: FRAIL Scale, assessing fatigue, resistance, ambulation, illness burden, and weight loss. • Follow Up: Postoperative assessments at 24 hrs, day 7, 6 weeks, and 3 months.
Outcomes Measured 1. Pain (VAS score) 2. Postoperative complications (classified using Clavien-Dindo system) 3. Recovery time and functional improvement 4. Length of hospitalization
Data Analysis Statistical tests (paired t-test, chi-square, ANOVA) will be used with significance set at p < 0.05.
Expected Impact Preoperative frailty screening will help: • Identify high-risk patients early, • Guide personalized care and rehabilitation plans, • Improve surgical decision-making and patient counseling |
