Retrospective review of 15 children treated for tibial intercondylar eminence fractures (3 Type I/II, 12 Type III) at mean 7-year follow-up. The central question: do these injuries produce persistent knee instability even after the fracture heals in anatomic position? This paper directly challenges the prior consensus that healing equals cure.
The textbook teaching before this paper was that intercondylar eminence fractures in children heal well and produce no instability — Garcia/Neer and Meyers/McKeever even excised the ACL fragment without apparent consequence.
This paper forces a different conversation with families. When you treat a child for a tibial spine fracture. Type I/II with casting or Type III with ORIF. Counsel parents that the ACL likely stretched before the bone failed, and that residual laxity is probable even after anatomic healing.
At follow-up, use the near-full-extension anterior drawer (Lachman-type) as your primary test. The pivot shift will be negative in most of these patients and will falsely reassure you.
The long-term concern the authors raise: these children may feel fine as teenagers but present with degenerative joint disease in their late 20s and 30s, mirroring the natural history of unaddressed ACL laxity in adults. A healed radiograph is not a healed knee.
