Thibau Nys (Lidl-Trek) has undergone successful surgery on his left knee to address prepatellar friction syndrome, the team confirmed on Friday, March 13. The procedure, a partial prepatellar fasciectomy performed at Herentals hospital in Belgium, requires a minimum of three and a half weeks of rest before Nys can resume training.
The condition involves chronic irritation of the soft tissue at the front of the kneecap. Lidl-Trek said Nys had been experiencing recurring knee pain stemming from a previous impact, with recent discomfort during training prompting the decision to operate. The team said Nys has returned home to begin his recovery.
"A return-to-competition date will be confirmed in due course as his recovery progresses," the team said.
The timing puts pressure on the 23-year-old's spring road programme. The prescribed rest period means Nys cannot begin training again until approximately April 7 at the earliest, which would leave very little time to build race fitness ahead of the Ardennes Classics later that month. Amstel Gold Race falls on April 19, La Flèche Wallonne on April 22 and Liège-Bastogne-Liège on April 26.
Nys had been expected to target those races as part of his road campaign, following a 2025 season in which he recorded top-ten finishes in the Ardennes.
Previous knee impacts
While the team did not specify which incident caused the underlying problem, Nys has sustained several significant knocks to the area across recent cyclo-cross seasons. He abandoned the 2023 Diegem Superprestige after falling on his knee, with a team doctor identifying a bruise next to one of the tendons. In November 2024, he was involved in a high-speed crash at Hamme, reporting afterwards that he hit the ground at 35 to 40 km/h and had trouble moving his knee. A month later, he was caught in a multi-rider pileup at the UCI Cyclocross World Cup in Dublin and forced to abandon.
The accumulation of those impacts appears to have produced the chronic friction that conservative treatment could not resolve, leading to Friday's surgical intervention. How quickly Nys can return to full competition remains uncertain, and the team gave no indication of specific race targets beyond the minimum rest window.
The current recovery schedule suggest a tentative possibility of Nys competing at the major Ardennes Classics.
