Summary
Women with chondromalacia patellae show distinct gait differences. Their knee flexion is reduced, and they exhibit altered femoral rotation during walking compared to healthy individuals.
Area of Science:
- Biomechanics
- Orthopedics
- Sports Medicine
Background:
- Chondromalacia patellae is a common condition causing anterior knee pain.
- Gait analysis is crucial for understanding lower limb biomechanics in knee conditions.
Purpose of the Study:
- To investigate and compare the gait patterns of women with and without chondromalacia patellae symptoms.
- To identify specific kinematic differences during walking on level and downhill surfaces.
Main Methods:
- High-speed cinematography was employed to capture gait kinematics.
- Subjects included women with and without chondromalacia patellae symptoms.
- Gait was analyzed on both a level surface and a 15° downhill slope.
Main Results:
- Chondromalacia patellae subjects demonstrated significantly reduced knee flexion during the single support phase (P < 0.05).
- Increased external femoral rotation was observed during the swing phase on both surfaces (P < 0.05).
- A marked inward femoral rotation occurred just before heel strike in the symptomatic group (P < 0.001).
Conclusions:
- Significant gait deviations are present in females experiencing chondromalacia patellae.
- These findings highlight altered knee and femoral mechanics during walking in this population.
- Gait analysis can aid in identifying and understanding chondromalacia patellae-related biomechanical changes.
