TKO (Technical Knockout) occurs when a fighter cannot safely continue in the match, as judged by the referee, while a KO (Knockout) is when a fighter is knocked unconscious or unable to get up from the canvas by the referee's count.

Key Differences
A TKO, or Technical Knockout, is called when a fighter is deemed unable to continue the fight due to injuries, exhaustion, or being overwhelmingly outperformed, even if they are still conscious. This decision is typically made by the referee, who acts in the interest of the fighter's safety. In contrast, a KO, or Knockout, involves a fighter being knocked unconscious or being so incapacitated that they cannot stand up before the referee counts to ten.
While TKOs are judgments based on the fighter's ability to defend themselves safely and effectively, KOs are clear and often sudden ends to a fight, with no ambiguity about the fighter's ability to continue. TKOs may involve a stoppage due to strikes, a corner stopping the fight, or even a doctor's intervention, whereas KOs are solely the result of a fighter's inability to physically continue.
TKOs are more common in situations where a fighter is still partially capable but has taken significant damage that could lead to serious injury if the fight continues. On the other hand, KOs leave no doubt as to the winner, as one fighter is unable to physically recover in the allotted time.
The determination of a TKO versus a KO depends heavily on the referee's interpretation and assessment of a fighter's condition and the potential for continued safe competition. A fight ending in TKO can be controversial, especially if the stopped fighter or their corner disagrees with the referee’s decision.
In the record books, both TKO and KO count as stoppages, which distinguishes them from decisions where the fight concludes after the scheduled rounds and goes to the judges' scorecards.
