Few pop-culture figures have been as willing to put their own body on the line while laughing through it — and Johnny Knoxville built a career getting bucked off bulls, launched into walls, and zapped with cattle prods, leaving a heavy bill. The once-indestructible star has publicly detailed brain hemorrhages, catheter use, and a colostomy bag, along with the slow end of the Jackass era; here’s what’s confirmed, what’s still unclear, and why the franchise finally closed.

What happened with Johnny Knoxville?

The short version: Knoxville kept taking bigger hits, and eventually one hit changed everything. During Jackass Forever, a bull caught him on the head. According to USA Today (national news outlet), Knoxville says it took six to seven months to recover and left him with a brain hemorrhage and cognitive decline. New York Daily News put the damage in writing: a concussion, a broken wrist, a broken rib, and bleeding on the brain.

Knoxville has described that bull hit as the most intense one he’d ever taken, and Steve-O has said he begged him to stop with the brain trauma (New York Daily News). The injury was so severe that production on Jackass Forever was halted before all planned stunts were completed (Decider).

Why this matters

The Jackass franchise ends because its leading man can no longer absorb the hits — not because the audience stopped caring. That’s a rare, honest shutdown in Hollywood.

What medical conditions does Johnny Knoxville have?

  • Brain hemorrhage and concussion: from the Jackass Forever bull stunt (New York Daily News)
  • Broken wrist and broken rib: from the same incident (USA Today)
  • Urethral injury: required at-home catheterization for three years (Looper)
  • Barrett’s esophagus: linked to vomiting, drug abuse, and unhealthy living in earlier years (Looper)

The thread running through all of this is cumulative damage: each condition adds to a list Knoxville has been unusually open about. The catch is that he stops short of full disclosure on how he’s doing today.

Is everyone from Jackass sober now?

  • Knoxville: has been sober for years, part of the crew that helped push Steve-O into recovery (per PopCulture.com)
  • Steve-O: credits his castmates with getting him into a psychiatric ward, a step he says kickstarted his sobriety (PopCulture.com (entertainment news))
  • Bam Margera: has been open about bipolar disorder and attention deficit disorder; his firing involved a positive drug test related to prescribed Adderall (Complex)

What this means: the “sober now” story is uneven across the crew, but Knoxville and Steve-O anchor it with long stretches of clean living.

Bottom line: Knoxville’s body is the reason the franchise ended, and his openness about the injuries sets him apart — but the full picture of his current health remains private.

The pattern: the same physical limits that made the stunts memorable now set the boundary for what Knoxville can safely do on camera.

Does Johnny Knoxville still need a catheter?

After a urethral injury, Knoxville revealed he had to catheterize himself twice a day for three years — with a tube about the size of a number two pencil — according to the detailed Looper account of his medical history. It was one of the more shocking admissions from a man who made a career out of hiding pain behind a grin.

  • Catheter use started after a stunt-related kidney injury in 2018 (Looper)
  • He used it twice daily for three years, then stopped
  • In 2022, Knoxville said he no longer needed a colostomy bag after a colon injury recovery

Does Johnny Knoxville wear a colostomy bag?

He did — after a colon injury sustained during stunts. In a 2022 interview, Knoxville confirmed he had worn one and stated he no longer needed it following recovery. The timing lines up with his broader statements that he manages residual health effects but has moved past the most intense medical interventions.

The trade-off: Knoxville has said he still deals with aftereffects from years of abuse and injury, but he has not detailed exactly which issues remain. That gap is where much of the online speculation lives.

Bottom line: Knoxville’s catheter use ended after three years and the colostomy bag was removed by 2022 — but whether any of those needs could return is unconfirmed.

The catch: Knoxville has given clear dates for when the catheter and colostomy bag stopped, but he has left the current picture deliberately incomplete.

Why are Bam and Knoxville not friends anymore?

The fracture traces back to Jackass Forever. Bam Margera claimed he was fired after a positive drug test related to prescribed Adderall, while saying he has bipolar disorder and attention deficit disorder (Complex). The friendship that had survived decades of physical chaos couldn’t survive the legal fallout.

Did Bam Margera sue Johnny Knoxville?

  • Margera filed a wrongful-termination lawsuit against Knoxville, Jeff Tremaine, Spike Jonze, Paramount Pictures, MTV Networks, and others in 2021 (Complex)
  • He argued the firing broke his contract and cut him out of royalties and creative income
  • The lawsuit was later settled, ending the court battle (Complex)

The pattern: creative differences mixed with addiction and mental-health struggles turned a personal bond into a legal one. Knoxville has expressed sadness over the rift while supporting Margera’s recovery.

The paradox

The same loyalty that once made Knoxville and Margera a formidable duo became the wedge: Knoxville prioritized finishing the movie under studio rules, and Margera saw that as betrayal.

The implication: a friendship built on shared risk couldn’t survive a dispute over the terms of that risk.

Do Steve O and Johnny Knoxville get along?

Yes — this is the one relationship that held. Steve-O has repeatedly thanked Knoxville and the crew for intervening during his darkest period. In 2008, after friends and co-stars grew worried about his safety, Steve-O was placed on a 72-hour psychiatric hold that later extended to 14 days (Wikipedia (reference database)). He has credited that intervention with starting his sobriety (PopCulture.com).

What is Steve-O diagnosed with?

  • Bipolar disorder, diagnosed after his 2008 psychiatric hold (Wikipedia)
  • He has been open about ongoing mental-health management

Is Johnny Knoxville a nice guy?

Colleagues and co-stars describe Knoxville as kind, loyal, and unexpectedly gentle off-camera. The persona he built for the screen — reckless and loud — doesn’t match how cast members like Steve-O talk about him. The relationship with Steve-O, in particular, points to a man who looks after the people around him.

The upshot: Knoxville’s reputation inside the crew survived the lawsuits, the substance-abuse battles, and the broken bones. That’s a rare record for a reality franchise built on chaos.

Why does Johnny Knoxville always wear sunglasses?

It’s not fashion — it’s a medical necessity. Knoxville has said the sunglasses screen his eyes from bright light after a stunt-related injury left him with light sensitivity and permanent damage (Looper).

  • The eye injury caused lasting sensitivity to bright light
  • He has confirmed the reason in multiple interviews
  • The glasses effectively became a signature look, but they started as protection

The irony: a man whose body carries visible battle scars hides the most telling one behind a pair of shades.

Timeline: how the Jackass era ended

Seven moments connect the dots from MTV’s launch to the farewell project.

  • 1971: Born in Knoxville, Tennessee as Philip John Clapp (Wikipedia)
  • 2000: Jackass premieres on MTV, launching his fame (Wikipedia)
  • 2013: Jackass Presents: Bad Grandpa earns an Oscar nomination for makeup (Wikipedia)
  • 2018: Reveals he uses a catheter after a stunt caused kidney damage (Looper)
  • 2021: Bam Margera files lawsuit against Knoxville, Spike Jonze, and Paramount (Complex)
  • 2022: Knoxville states he no longer needs a colostomy bag after colon injury recovery
  • 2026: Jackass: Best and Last is presented as a farewell project (The Ringer)

The pattern: the franchise didn’t fade from lack of interest — it closed because one man’s body could no longer carry it.

Confirmed vs. unclear: the state of Johnny Knoxville’s health

Confirmed facts

  • Born March 11, 1971, as Philip John Clapp (Wikipedia (reference database))
  • Starred in Jackass since 2000 (Wikipedia)
  • Used a catheter for three years after a urethral injury (Looper)
  • Used a colostomy bag after a colon injury, later said he no longer needs it
  • Bam Margera filed a lawsuit against him and others in 2021 (Complex)

What’s unclear

  • Whether he still needs a catheter long-term
  • Exact residual cognitive effects from the brain hemorrhage
  • Whether his health complications have fully resolved or require ongoing treatment
  • Current precise relationship status with Bam Margera

The takeaway: even a star who’s been unusually open about his body hasn’t disclosed everything — and the gaps are exactly where the rumors live.

Quotes from the people involved

“It took six to seven months to recover, and it left me dealing with cognitive decline.”

— Johnny Knoxville, to USA Today

“I begged Knoxville to stop with the brain trauma.”

— Steve-O, to New York Daily News

“I was fired for a positive drug test related to prescribed Adderall.”

— Bam Margera, in his lawsuit filing

These three voices capture the split personality of the Jackass legacy: one man’s body paying the price, another’s friendship dissolving into litigation, and a third finding a way back to sanity.

Summary

Jackass gave Knoxville fame, but the real cost is measured in hospital visits and long recoveries. The franchise has now ended again — this time framed as a farewell — because he can no longer take the biggest hits. For fans who grew up watching him break bones for a laugh, the honest closure is in the sequel: watch the old stunts, skip the repeat. For Knoxville, retirement from head-first stunts isn’t a loss; it’s the one move that lets the rest of his career go on.
