Summary
Ankle surgery significantly improved joint position sense, resolving preoperative deficits in injured ankles. This suggests that proprioceptive issues contribute to functional instability, and surgical repair of anterolateral structures is key for recovery.
Area of Science:
- Orthopedic Surgery
- Sports Medicine
- Biomechanics
Background:
- Ankle proprioception's response to surgical intervention remains under-investigated in scientific literature.
- Functional instability in ankles is often linked to proprioceptive deficits.
Purpose of the Study:
- To evaluate the impact of anatomical reconstruction of the anterolateral capsuloligamentous complex on ankle joint position sense.
Main Methods:
- Prospective study utilizing the "slope box" test.
- Involved ten patients undergoing surgery and ten healthy athletes as a control group.
Main Results:
- Post-surgery, preoperative differences in joint position sense errors between injured and healthy ankles were eliminated.
- Significant improvement in ankle joint position sense was observed in the surgical group in anterior and lateral directions.
- The "slope box" test demonstrated high reliability (0.92) and no significant side dominance effects.
Conclusions:
- Anatomical reconstruction surgery effectively restores joint position sense in injured ankles.
- Proprioceptive malfunction is a significant factor in ankle functional instability.
- Surgical retensioning of anterolateral structures is crucial for ankle repair, regardless of specific grafting techniques.
