This prospective cohort study from a Level I trauma center enrolled 120 adults with femoral shaft, acetabular, or unstable pelvic fractures. It addressed two unanswered questions: does distal femoral traction cause knee dysfunction, and is traction better than splinting for acute pain control?
When a patient returns to clinic after femoral shaft fracture fixation complaining that their knee pain is from the old traction pin, this study gives you a data-driven answer: it probably is not. Lysholm scores declined equally in both the traction and splint groups, meaning the injury and its treatment are responsible — not the pin.
For the acute setting, traction is the better choice for pain control during immobilization. The difference of 1.9 VAS points exceeds the minimum clinically significant threshold of 1.3 points, and the 2mm K-wire produces the least pain of any option.
The Lysholm scoring system is the outcome tool used here and is worth knowing for boards: 95-100: excellent 84-94: good 65-83: fair Below 65: poor Normal adults without knee pathology average 94 points.
A critical appraisal point: this was not randomized — attending preference drove group assignment. Selection bias is possible, but the baseline Lysholm scores were identical across groups, which partially mitigates this concern.
