Summary
The patellar tendon/patella ratio and patellofemoral congruence were measured in 118 knees. A positive correlation indicates that a higher ratio is linked to patellofemoral incongruence, suggesting a high-riding patella.
Area of Science:
- Orthopedic surgery
- Biomechanics
- Radiology
Background:
- Patellofemoral incongruence is a common cause of knee pain.
- The patellar tendon/patella ratio is a radiographic measurement used to assess patellar position.
Purpose of the Study:
- To investigate the correlation between the patellar tendon/patella ratio and patellofemoral congruence.
- To determine if the patellar tendon/patella ratio can predict patellofemoral incongruence.
Main Methods:
- Radiographic measurements of the patellar tendon/patella ratio were performed on 118 knees.
- Patellofemoral congruence was assessed using established criteria.
- Statistical analysis was used to determine the correlation between the two measurements.
Main Results:
- A statistically significant positive correlation was found between the patellar tendon/patella ratio and patellofemoral incongruence.
- A higher patellar tendon/patella ratio was associated with increased patellofemoral incongruence.
- High-riding patella was observed in knees with patellofemoral incongruence.
Conclusions:
- The patellar tendon/patella ratio is a reliable indicator of patellofemoral incongruence.
- This measurement may aid in the diagnosis and management of patellofemoral pain syndrome.
- Further research is warranted to explore the clinical implications of this finding.
