Summary
Improved balance, not just pain relief, significantly impacts total knee replacement (TKR) success. Post-TKR rehabilitation should prioritize balance training for better patient outcomes and mobility.
Area of Science:
- Orthopedics
- Rehabilitation Science
- Biomechanics
Background:
- Total knee replacement (TKR) aims to alleviate pain and restore function.
- Patient outcomes after TKR are influenced by various factors, including pain and physical function.
- The specific role of balance in TKR success requires further investigation.
Purpose of the Study:
- To investigate the correlation between improved balance and the success of total knee replacement (TKR).
- To determine if balance improvement is a significant predictor of TKR outcomes beyond pain relief.
Main Methods:
- A cohort of 81 patients undergoing TKR was recruited.
- 62 patients underwent static and dynamic balance assessments pre-operatively and one year post-operatively using validated equipment.
- Motor function and self-reported outcomes were also evaluated.
Main Results:
- A significant improvement in dynamic balance was observed one year after TKR (p < 0.001).
- Enhanced balance correlated positively with improved mobility, functional balance, and health-related quality of life.
- Balance improvement emerged as a key factor in TKR success, alongside pain relief.
Conclusions:
- Balance plays a crucial role in the overall success of total knee replacement.
- Post-operative rehabilitation protocols for TKR should incorporate targeted balance training.
- Addressing balance deficits can optimize functional recovery and patient satisfaction after TKR.
