Purpose: The difference in ultimate strength between the quadriceps and
patellar tendon could be reflected by different morphologic features.
Methods: Standardized samples of quadriceps and patellar tendons were
harvested from 20 cadavers and were investigated via light and electron
microscopy, immunohistochemistry, and morphometry. The thickness of
collagen fibrils, fibrilinterstitium ratio, density of blood vessels,
density of fibroblasts, and distribution of collagen fibrils were
analyzed. Results: In comparison with the patellar tendon, the
quadriceps tendon showed a significantly higher fibril-interstitium
ratio (P =.0004) and a higher fibroblast density (P =.0011). No
differences regarding the thickness of collagen fibrils, density of
blood vessels, and distribution of fibrils were found. Conclusions: The
quadriceps tendon graft can provide approximately 20% more collagen
than the patellar tendon graft with the same thickness. This fact can
play an important role in the better ultimate strength of the quadriceps
tendon. Clinical Relevance: The detailed anatomic description of the
quadriceps tendon and patellar tendon explains the difference in their
ultimate strength.
