The 2026 FIFA World Cup is underway amid a wave of high-profile knee injuries that has been unprecedented in its scale. Rodrygo, the Brazil and Real Madrid forward, has been ruled out after tearing his ACL and meniscus in March. Netherlands midfielder Xavi Simons ruptured his ACL in April and will miss the tournament entirely. Canada’s Marcelo Flores suffered the same injury just days before the squad deadline. Football’s governing bodies continue to debate the role of an increasingly congested calendar in driving injury rates.
For many players, the road ahead will involve not just one operation, but the possibility of revision surgery if their initial reconstruction does not hold. Revision ACL reconstruction is a procedure that is becoming more common across all levels of sport, and one that demands a considerably higher level of surgical expertise than a primary repair.
What is revision ACL reconstruction surgery?
The anterior cruciate ligament (ACL) is one of the key stabilising structures of the knee, running diagonally through the joint and controlling rotational movement. When it ruptures, ACL reconstruction surgery uses a graft, typically taken from the patient’s own hamstring or patella tendon, to replace the damaged ligament.
In some cases, this reconstruction fails. The graft may rupture, loosen, or not integrate correctly with the surrounding bone. When this happens, a further operation, known as revision ACL reconstruction, is required. This is a significantly more complex procedure than the original surgery for several reasons: graft options may be more limited, bone tunnels from the first operation can interfere with the new surgical approach, and the surrounding structures of the knee are often compromised.
Why outcomes differ from primary surgery
The evidence consistently shows that revision ACL reconstruction carries a higher risk of further problems and a lower likelihood of returning to the same level of sport than primary reconstruction.
A large multicentre study published in the Journal of Bone and Joint Surgery (MARS Group, 2019), followed 843 patients who underwent revision reconstruction and tracked their progress over two years. It found that rehabilitation-related decisions made at the time of surgery had a measurable impact on clinical outcomes. Patients prescribed a functional brace for their return to sport showed better knee function scores at two years, while early postoperative bracing was associated with an increased likelihood of requiring further surgery. The study highlighted how closely surgical and rehabilitation decisions are intertwined in determining long-term success after revision surgery.
This complexity is also reflected in guidance from the British Orthopaedic Association, which recognises that revision surgery presents particular technical challenges around graft selection, tunnel placement, and the management of any concurrent ligament or cartilage damage that may have developed since the original operation.
The importance of not returning to sport too soon
One of the clearest findings in the ACL literature concerns timing. Research published in the Journal of Orthopaedic and Sports Physical Therapy found that athletes who returned to sport within nine months of ACL reconstruction had a rate of re-injury seven times higher than those who delayed their return beyond that point. For players facing revision surgery, the stakes of a premature return are even greater.
The injury toll ahead of this World Cup is a reminder of what happens when recovery timelines are compressed.
Can patients return to sport after revision ACL surgery?
Return to sport is possible after revision ACL reconstruction, but the outcomes are generally less predictable than after primary surgery.
The good news is that with experienced surgical technique, appropriate graft selection, and a disciplined rehabilitation approach, many patients do successfully return to high levels of activity. The key is ensuring that every decision, from the planning stage through to the final stages of rehabilitation, is made with the individual’s specific circumstances in mind.
If you have experienced an ACL injury and are concerned about the outcome of a previous reconstruction, or if you have been advised that revision surgery may be necessary, a specialist assessment with Mr Punwar can help determine the most appropriate course of action.
