Fencing Injury Report: How Top Stars Are Managing Overuse Ahead of the Hong Kong World Championships

The 2025-2026 international fencing season has been a grueling marathon, and as the sport's elite prepare for the Senior World Championships in Hong Kong this July, the focus has shifted from piste tactics to the treatment table. Unlike contact sports where acute trauma dominates, fencing's primary adversary is the silent, compounding toll of chronic strain. For the world's top athletes, managing these nagging injuries has become the defining factor in whether they will contend for a medal or watch from the sidelines.[1][3]

Hong Kong's own Cheung Ka-long, the two-time Olympic foil champion, is the highest-profile star currently navigating this delicate balance. Following a stunning early exit at the previous World Championships in Tbilisi, Cheung took an extended break from the strip to let his body heal. He has been transparent about the physical cost of his Olympic runs, noting that he is dealing with a significant number of injuries stemming purely from overuse.[1]

To ensure he is ready for the home crowd in Hong Kong—and to keep his hopes alive for an unprecedented third consecutive Olympic gold in Los Angeles—Cheung and his coach, Greg Koenig, have overhauled his regimen. Rather than pushing through the pain, Cheung is actively load-managing, focusing on targeted strength training to build muscle around his damaged joints. This proactive approach aims to absorb the explosive impact of his lunges and reduce the strain on his knees and ankles.[1]

Cheung's struggles highlight a broader reality within the sport. While fencing is statistically one of the safest Olympic disciplines regarding sudden collisions, the repetitive, asymmetrical nature of the movements exacts a heavy price over time. American foilist Miles Chamley-Watson has frequently dispelled the myth that fencing is a gentle pursuit, pointing out that anterior cruciate ligament (ACL) and medial collateral ligament (MCL) tears are incredibly common among elite competitors, alongside broken fingers and chronic joint degradation.[5]

Recent data backs up these anecdotal experiences. In February 2026, USA Fencing released a comprehensive six-season analysis covering more than 637,000 direct elimination bouts. The findings were overwhelmingly positive regarding acute tournament safety: the medical withdrawal rate was a microscopic 0.338%, meaning only about one in every 296 bouts ended due to a medical issue.[2]

However, tournament withdrawals only tell half the story. A landmark April 2026 study published in The Physician and Sportsmedicine tracked elite fencers over a 12-month period and found that overuse injuries during training are the true epidemic. The study recorded an incidence of 3.22 injuries per 1,000 training hours, with overuse injuries occurring at more than four times the rate of acute trauma.[3]

The anatomical distribution of these injuries is highly predictable. The lower extremities—particularly the knees, ankles, and hips—account for nearly 58% of all reported issues, a direct result of the explosive, repetitive lunging and sudden directional changes required on the piste. Sabre fencers, who rely on rapid, sprinting footwork, exhibited the highest injury rates, followed by epee and foil practitioners. Unsurprisingly, ligament injuries required the longest return-to-sport rehabilitation periods.[3]

The biomechanics of the sport explain the damage. A fencer's lead knee absorbs immense braking forces during the culmination of a lunge, while the trailing ankle and Achilles tendon endure extreme tension during the explosive push-off. Over thousands of repetitions, the cartilage and ligaments in these joints begin to fray. Female athletes, according to the cohort data, reported a significantly higher incidence of these training-related injuries than their male counterparts, prompting calls for sex-specific load management protocols.[3]

For veterans of the sport, surviving the calendar requires treating recovery as a second full-time job. American sabre star Eli Dershwitz, who is pushing toward the 2028 cycle, considers his meticulous approach to rehab, hydration, and mobility to be a non-negotiable necessity. Dershwitz has noted that without strict diligence to injury prevention, a fencer's body simply cannot survive the modern international circuit.[6]

Recognizing the growing physical demands on its athletes, the International Fencing Federation (FIE) is taking systemic action. On July 23, 2026, alongside the Senior World Championships, the FIE will host the inaugural Hong Kong Sports Medicine Conference. The event represents a major milestone in the governing body's 2025–2028 strategic plan, shifting the organizational focus heavily toward athlete safety and longevity.[4]

The conference will bring together sports physicians, physiotherapists, and biomechanics experts to address the exact overuse patterns plaguing fencers like Cheung. A key initiative being rolled out is the Fencing Injury Surveillance System (FISS), a data-driven platform designed to track injury epidemiology globally. By monitoring training loads and biomechanical stressors, the FIE hopes to develop weapon-specific prevention strategies that can be implemented at the club level.[3][4]

Ultimately, the 2026 season marks a turning point in how the sport handles physical attrition. The old-school mentality of fencing through chronic pain is being replaced by strategic load management, data-backed rehabilitation, and institutional support. For stars like Cheung Ka-long, this modern approach to sports medicine isn't just about surviving the next tournament—it's about rewriting the limits of a fencing career.[1][4]
