It’s called the “oblique kick” because of a mix of anatomy terminology , commentator influence, and how the strike actually hits the leg.

Core idea in one line

In MMA, “oblique kick” is basically a nickname for a straight, stomping-style kick to the front of the opponent’s knee that threatens the oblique (angled) ligaments and joint line of the knee rather than the belly or head.

Where the name came from

  • The label “oblique kick” became popular through UFC commentary, especially Joe Rogan during the early 2010s, when Jon Jones started using it constantly.
  • Before that, similar kicks existed in arts like Savate (chasse frontal bas) and Wing Chun, but under different names like low front kick, knee stomp, or cross-step kick.

Why “oblique” specifically?

There are two main explanations people point to in discussions and breakdowns:

  1. Oblique ligaments / oblique angle of the knee
    • The kick is aimed just above or into the front of the knee, in a way that can hyperextend the joint and stress the MCL/ACL and related structures sometimes loosely referred to in commentary as “oblique” ligaments or fibers.
 * Because the kick drives the knee backward at a slight angle instead of just straight up like a teep to the body, the name “oblique” stuck as a descriptive shortcut.
  1. Oblique as “slanted/diagonal” movement
    • In general English and in biomechanics, “oblique” means slanted or diagonal, not purely vertical or horizontal.
    • The common version of this kick in MMA is a stomping push that often travels along a slightly downward or diagonal line to the opponent’s front leg, not a pure straight snap like a typical front kick.

So, the name is more descriptive slang than strict textbook anatomy—it captures that it’s a straight-looking kick that attacks the knee in a slightly off‑angle, joint‑threatening way rather than a normal leg kick.

What it’s actually called in traditional arts

  • In Savate, a very similar technique is called “chasse frontal bas” (low front thrust kick).
  • In some Wing Chun lineages, a similar motion is referred to as a type of cross‑van or oblique kick to the knee/quad for stopping power.
  • In many kickboxing or karate contexts, coaches just say “side kick to the knee” or “knee stomp,” and the “oblique” label only really caught fire in modern MMA talk.

Quick recap

  • The move existed long before but had other names in traditional systems.
  • MMA fans and commentators popularized “oblique kick” as a catchy term when fighters like Jon Jones used it a lot.
  • “Oblique” here loosely refers to the angled, joint‑attacking nature of the kick to the front of the knee rather than a precise textbook anatomical term.
