Summary
Total knee replacement (TKR) significantly improves patient satisfaction, pain management, and mobility. Post-surgery outcomes show enhanced quality of life and functional independence for TKR patients.
Area of Science:
- Orthopedics
- Rehabilitation Medicine
- Patient-Reported Outcomes
Background:
- Despite high patient satisfaction with total knee replacement (TKR), concerns persist regarding post-operative pain and mobility.
- Variability in patient satisfaction levels after TKR warrants further investigation.
Purpose of the Study:
- To prospectively evaluate patient-reported outcomes and functional recovery after TKR.
- To assess changes in pain, mobility, and quality of life at least 6 months post-surgery.
Main Methods:
- Utilized the Knee injury and Osteoarthritis Outcome Score (KOOS), SF-36 health survey, and Timed Up and Go (TUG) test.
- Measured functional recovery using the 6-minute walk test (6MWT).
- Prospective evaluation of patients at 6 months post-TKR.
Main Results:
- KOOS Pain scores improved significantly from 45.6 pre-surgery to 82.1 post-surgery.
- SF-36 physical functioning scores increased from 41.2 to 80.5 (p<0.001).
- TUG test times decreased from 18.4 to 10.2 seconds, and 6MWT distances increased from 230.7 to 360.8 meters (p<0.001).
Conclusions:
- Total knee replacement leads to significant improvements in patient satisfaction.
- TKR enhances functional independence and overall quality of life.
- Objective functional measures and patient-reported outcomes confirm TKR's efficacy.
