→ See all Sirloin tip substitutes by country

The knuckle muscle group at the front of the rear leg, between the sirloin and the round — anatomically the *quadriceps* (rectus femoris and surrounding muscles). Leaner than the rump but tenderer than the silverside, with a fine even grain that makes it a workhorse for roasts, breaded cutlets, and quick steaks. Almost every butchery tradition isolates it under a different name: *sirloin tip* or *knuckle* in the US, *top rump* or *thick flank* in the UK, *bola de lomo* in Argentina (the milanesa cut), *babilla* in Spain, *patinho* in Brazil, *noix* in France, *noce* in Italy. Cooks well as a small whole roast (cooked rare and sliced thin), as cubes for stews, or pounded thin for milanesas/schnitzel.

Similar cuts

Poireapproximate

Both round-area muscles, but anatomically distinct — sirloin tip is the front-knuckle quadriceps, poire is a smaller pear-shaped muscle on the inside thigh. Poire is the French-butchery boucher's secret, sirloin tip is the broader US/Anglo cut.

Topside
Topsideapproximate

Sister cut on the round — sirloin tip is the front knuckle (quadriceps), topside is the inner thigh (adductor). Both lean roasting cuts, sirloin tip is the slightly tenderer of the two.

Bottom round
Bottom roundapproximate

Both lean round subprimals. Bottom round (silverside) is the harder outer-thigh group; sirloin tip (knuckle) is the front-thigh quadriceps and is naturally tenderer.
