Objective:To discuss the efficacy of absorbable cartilage screws internal fixation in treatment of tibial intercondylar eminence fracture in children. Methods:From March 2007 to March 2014

41 pediatric cases(male 27

female 14) with an average age of10.4 years(range from 6 to 14 years) who suffered tibial intercondylar eminence fracture underwent surgery treatment. According to the modified classification of Meyers and Mc Keever

there were 15 type Ⅱ

18 type Ⅲ

and 8 type Ⅳ fractures. All of these patients received the operation between 2 d and 7 d with an average of 3.8 d. Among them

19 cases were treated by absorbable cartilage screws under arthroscopy and the other 22 cases were treated with open reduction and internal using absorbable cartilage screws.Brace external fixation were carried out postoperatively at 4-6 weeks;X-ray was rechecked regularly;knee joint function was evaluated according to Lysholm scores. Results:All the patients were followed from 12 months to 48 months with an average of 24 months. The wounds were healed by the first intention. The average healing time was 7.9 weeks(6-12 weeks). Two cases showed stiff knee and flexion restriction three months later

all recovered to 5° to 120° flexion after physical therapy combined with CPM. Slight limitation of knee extension was found in 6 cases at 6 month after operation. For Lysholm scores of all patients

33 cases were excellent

6 cases were good

2 cases were fair and none was poor

the total excellent and good rate was 95.12%. The Lysholm knee scores were increased from preoperative 46.1±3.2 to the latest follow-up 95.5±1.2. A paired t-test was also conducted to find out the difference was statistically significant(t=58.7

P=0.000). Conclusion:Taking into consideration the advantages of relative stability

no significant damage to the epiphysis

quick recovery of knee joint function

avoiding the second operation to remove the internal fixation

absorbable cartilage screws internal fixation is effective in treatment of tibial intercondylar eminence fracture in children.
