    Knee trauma: fractures and injuries requiring surgery

    Under «knee trauma» very different worlds coexist: bone, cartilage, ligaments, menisci. Surgery comes into play when the picture cannot be solved with bracing, rehabilitation and time.

    A child's and adolescent's knee is not a smaller adult knee. The presence of growth plates (distal femur and proximal tibia) changes X-ray reading, technique choice and long-term follow-up.

    The most common surgical lesions

    Tibial spine avulsion (intercondylar eminence)

    A typical paediatric/adolescent lesion: the ACL insertion detaches with a bony fragment. Treated arthroscopically with dedicated wires or screws.

    Displaced fragments preventing full extension or destabilising the knee.

    It is different from the classic adult ACL tear, even if the mechanisms are similar.

    Osteochondral lesions and osteochondritis dissecans

    When a cartilage and underlying bone fragment detaches or risks detaching. Depending on stage: fragment fixation, microfractures, cartilage regeneration procedures.

    Unstable, symptomatic fragments not responding to conservative treatment.

    Distal femur fractures — Salter-Harris

    Fractures involving the distal femoral growth plate. Depending on type, reduction and fixation with screws or wires, often with minimally invasive technique.

    Displaced or intra-articular forms; care is taken not to damage the physis further.

    Long-term follow-up is required to catch any growth disturbance.

    Proximal tibia fractures

    Including metaphyseal and proximal physeal fractures. Screw or wire fixation, axis control.

    Displaced or unstable forms, especially when the physis or joint is involved.

    Patellar dislocation with osteochondral fragment

    After a first patellar dislocation a fragment may detach from the patella or femoral condyle. MRI assessment; if significant, arthroscopic or open refixation.

    Loose intra-articular fragment, joint locking, recurrent patellar instability.

    When the problem is not surgical

    Many knee traumas in children and adolescents resolve with bracing, rehabilitation and time. MRI should be prescribed with judgement: it is useful when it can change the decision, not to «see everything».

    Frequently asked questions

    Can ligaments be operated on in a growing child?

    Yes, but with techniques designed not to damage the growth plates. The decision considers age, sport, instability and associated picture.

    Will my child return to the same sport?

    In many cases yes, with a serious rehabilitation pathway and timing that depends on the lesion and surgery. Skipping stages is the main cause of recurrence.

    A second opinion on a paediatric fracture

    Bring the ER report and the X-rays. A focused paediatric orthopaedic visit can clarify indication, timing and alternatives.
