Summary
Kinesthesia is impaired after anterior cruciate ligament (ACL) reconstruction but adapts within 12 months. An angular velocity of 0.2°/s is appropriate for assessing this sensory function in ACL patients.
Area of Science:
- Orthopedics
- Neuroscience
- Sports Medicine
Background:
- Kinesthesia assessment lacks consensus post-anterior cruciate ligament (ACL) reconstruction.
- Understanding kinesthetic adaptation is crucial for rehabilitation protocols.
Purpose of the Study:
- To prospectively evaluate kinesthetic adaptation after ACL reconstruction.
- To determine the optimal angular velocity for kinesthesia assessment in ACL-reconstructed patients.
Main Methods:
- Prospective study involving 31 patients undergoing ACL reconstruction.
- Threshold to Detect Passive Motion (TTDPM) test administered preoperatively and at 3, 6, and 12 months post-surgery.
- TTDPM measured at 15° and 45° knee flexion using 0.1°/s and 0.2°/s angular velocities.
Main Results:
- Preoperatively, ACL-reconstructed knees showed significantly impaired TTDPM at 0.2°/s compared to healthy knees.
- No significant differences in TTDPM were observed at the 3-month follow-up.
- Kinesthesia, sensory function, and biomechanical stability adapted within 12 months post-ACL reconstruction.
Conclusions:
- An angular velocity of 0.2°/s is suitable for assessing TTDPM in ACL-reconstructed patients.
- Kinesthetic adaptation occurs by 12 months after ACL reconstruction.
- Rehabilitation effectively restores sensory function and biomechanical stability.
