Description: The TKA Outcome Score is a patient-reported outcome measure designed to evaluate the symptoms, function, and overall knee-related quality of life in patients who have undergone total knee arthroplasty (knee replacement surgery). It is widely used to assess the effectiveness of the surgery and monitor postoperative recovery.
Conditions Measured:
Number of Items: Various (Typically tailored to specific assessment tools)
Estimated Time to Complete: 10-15 minutes
Scoring Method: The TKA Outcome Score typically includes multiple domains such as pain, knee function, and quality of life. Each domain may have several items scored on a varying scale. Scores are often transformed to a 0-100 scale, with higher scores indicating better knee function and fewer symptoms.
Reliability: The TKA Outcome Score has demonstrated high test-retest reliability and internal consistency across different patient populations.
Validity: Numerous studies have validated the TKA Outcome Score, showing strong construct validity, responsiveness, and sensitivity to changes in knee conditions post-surgery.
