Summary
Assessing outcomes after total knee replacement (TKR) requires both patient-reported scores and functional tests. The Timed Up and Go Test effectively correlates with patient perceptions of pain and function post-TKR.
Area of Science:
- Orthopedics
- Rehabilitation Medicine
- Biomedical Engineering
Background:
- Quantifying outcomes after total knee replacement (TKR) often relies on various patient-reported scores.
- Limited research exists on the correlation between these subjective scores and objective functional tests post-TKR.
Purpose of the Study:
- To evaluate the relationships between commonly used patient-reported outcome scores and objective functional measurements following TKR.
- To determine the validity of functional tests in reflecting patient experiences after total knee replacement.
Main Methods:
- A prospective cohort study involving 24 patients who underwent unilateral TKR.
- Assessment included four patient-reported outcome scores, knee laxity, quadriceps muscle strength, and the Timed Up and Go Test.
- Pearson product moment correlation coefficient was used to analyze the relationships between all scores and measures.
Main Results:
- The Timed Up and Go Test demonstrated a statistically significant correlation with patient-reported scores (r = -0.557 to -0.770, P = 0.0001-0.005).
- No other objective measures showed a statistically significant correlation with patient-reported outcomes.
Conclusions:
- Comprehensive assessment of TKR outcomes necessitates integrating both subjective patient reports and objective functional measures.
- Walking ability and speed, as measured by the Timed Up and Go Test, are crucial indicators of pain and function for TKR patients.
