What are the myths about a failed ACL graft and revision surgery?

Myth: it must be the surgeon's fault

Technical factors such as tunnel position do contribute in some cases, but grafts also fail because of new injuries, early return to sport, biological reasons, bone shape such as a steep tibial slope, or other loose ligaments. Often several factors combine. Understanding the cause is more useful than assigning blame, because it guides the revision.

Myth: it must be the patient's fault

Patients often feel guilty after a re-tear, wondering if they did too much. Sometimes a return to sport was early, but many re-tears happen after doing everything right. A new injury in pivoting sport can tear even a well-placed, mature graft.

More myths, briefly

• The knee is finished: many people regain a stable knee after revision
• Revision always needs two operations: many are done in one stage; two stages are used when tunnels are widened or badly placed
• You cannot use your own tendon again: other tendons, from the same or the other knee, are often available
• Revision is the only option: some people manage well with rehabilitation and activity changes
• Results are the same as the first time: outcomes are usually less predictable, and expectations should reflect that

Getting a clear picture

A careful review of your history, the first operation notes, X-rays, CT and MRI shows why the graft failed and what can be done. At Aman Hospital in Doha, Dr. Gelber explains the findings plainly and discusses whether revision, rehabilitation or another approach suits your goals.
