Summary
Unilateral triple or double arthrodesis effectively reduces pain and improves function in patients without other lower extremity issues. Gait analysis reveals altered knee and ankle motion and reduced ankle power generation post-surgery.
Area of Science:
- Orthopedic Surgery
- Biomechanics
- Gait Analysis
Background:
- Triple or double arthrodesis is a surgical procedure to fuse joints in the foot and ankle.
- Assessing long-term outcomes and biomechanical changes after these procedures is crucial for patient management.
Purpose of the Study:
- To evaluate the clinical and radiological outcomes and gait biomechanics in patients who underwent unilateral triple or double arthrodesis.
- To determine the correlation between radiological findings and patient-reported pain and function.
Main Methods:
- Clinical assessment using the American Orthopaedic Ankle and Foot Society score.
- Radiological evaluation for arthrosis progression.
- Three-dimensional kinematic and kinetic gait analysis.
Main Results:
- 10 out of 13 patients reported good or excellent outcomes.
- No significant correlation between radiological arthritis and pain/disability.
- Gait analysis showed increased ipsilateral knee flexion, reduced ankle range of motion, and decreased ankle power generation.
Conclusions:
- Unilateral triple or double arthrodesis leads to predictable improvements in pain and function for selected patients.
- The procedure results in significant biomechanical alterations in gait, including reduced ankle motion and power.
