Long-term follow-up of anterior tibial spine fractures in children.
In a long-term follow-up (mean 16 years) of 61 children with anterior tibial spine fractures, subjective knee function (Lysholm score) was excellent or good in 87% of the subjects and fair in 13%. Eleven percent of the children had a lower activity level (Tegner score) than desired. Muscle performance was affected in those subjects with the lowest Lysholm scores. Pathological knee laxity was found in 38% of the subjects, but was not reflected in poor subjective knee function. Age at injury did not influence the outcome. There was no indication that young children can eliminate slackness of the anterior cruciate ligament by further growth. Only in type III fractures was there a correlation between fracture displacement after healing and knee laxity, as well as between knee laxity and Lysholm score. Arthroscopy-guided or open reduction and internal fixation seems to be a worthwhile procedure only in dislocated type III fractures.
