Tendon vs Top Sirloin — What's the Difference?
Quick Answer
Tendon (beef tendon) and Top Sirloin (top sirloin) are not the same cut: Tendon is offal primal (Connective tissue at joints — particularly the hock/lower leg); Top Sirloin is sirloin primal (Upper hip, above the sirloin cap (coulotte) and behind the short loin).

Side-by-side
| tendon | top sirloin | |
|---|---|---|
| Primal | offal | sirloin |
| Muscle / location | Connective tissue at joints — particularly the hock/lower leg | Upper hip, above the sirloin cap (coulotte) and behind the short loin |
| Character | Collagen-rich connective tissue extracted from the leg joints, particularly the Achilles tendon area. Extremely gelatinous when slow-cooked; provides body and sticky texture to braises and soups. Prized in Korean, Vietnamese, and South Asian cuisine for its chew and the richness it adds to broth. | A large, lean cut from the hip section. The top sirloin butt (NAMP 184) is the main muscle group. Versatile — grilled as steaks, roasted whole, or cut into kabobs. Moderate tenderness with good beefy flavor. Not to be confused with sirloin cap (coulotte/picanha) which sits on top of it. |
Key differences
- Different primals: offal vs sirloin.
- Texture and slicing: compare fibrous, grain-heavy cuts vs more tender steak-style muscles based on each cut’s description.
- Retail naming diverges by country—always map through a canonical cut when translating menus or labels.
When to use each
Tendon
