Morphometric Analysis of Dry Human Patella and Patellar Facets

Area of Science:

• Orthopedic Surgery
• Forensic Anthropology
• Anatomy

Background:

• The patella, or kneecap, is the largest sesamoid bone, crucial for knee joint protection.
• Its unique structure, lacking periosteum, complicates natural healing and necessitates precise surgical interventions.
• Accurate patellar morphometry is vital for forensic analysis, implant design, and knee reconstruction.

Purpose of the Study:

• To conduct a comprehensive morphometric analysis of the patella.
• To compare morphometric parameters between right and left-sided patellar specimens.

Main Methods:

• Analysis of 50 dry patella specimens (26 left, 24 right).
• Measurement of key parameters: height, width, thickness, articular facet dimensions (medial and lateral), and central ridge length.
• Statistical comparison of measurements between sides, with p<0.05 considered significant.

Main Results:

• Mean patellar dimensions: height (4.07 cm), width (4.12 cm), thickness (2.03 cm).
• Statistically significant variations (p<0.05) were observed between the lateral and medial articular facets.
• 92% of specimens classified as Type B according to Koyunco's Classification.

Conclusions:

• Patellar morphometry data provides essential information for orthopedic surgeons.
• Findings support the design of improved implants for knee replacement and patellar reconstruction.
• Accurate dimensional data aids in successful patellar fixation procedures.
