[High strength wire under arthroscopy combined with outside anchor nail in treating Meyers McKeever II, III avulsion fracture of anterior cruciate ligament tibial check point].

OBJECTIVE: To explore clinical effect of high strength wire under arthroscopy combined with outside anchor nail in treating Meyers McKeever II, III anterior cruciate ligament tibial check point. METHODS: From March 2014 to June 2016, 21 patients with Meyers McKeever II, III avulsion fracture of anterior cruciate ligament tibial check point were treated by high strength wire under arthroscopy combined outside anchor nail. There were 13 males and 8 females aged from 18 to 48 years old with an average of (26.40±5.42) years old. There were 9 cases injured on the left side, and 12 cases on the right side. The courses of disease included sports injuries of 12 cases, falling down injuries of 6 cases, and accident injuries of 3 cases. According to Meyers-McKeever classification, 16 patients were type II and 5 patients were type III. All fractures were fresh, closed and simple injury. The time from injury to operation ranged from 2 to 15 days with an average of (6.20±2.63) d. Lysholm score, IKDC score and the changes of knee mobility were observed and compared before operation and 6 months after operation. RESULTS: Twenty-one patients were followed up for 12 to 24 months with an average of (14.30±3.01) months. Operation time ranged from 40 to 65 min with an average of (45.10±4.82) min, Blood loss ranged from 5 to 15 ml with an average of (10.05±2.75) ml. Lysholm score was improved from 50.29±6.67 before operation to 92.48±2.18 at 6 months after operation. IKDC scores was increased from 47.19±4.57 before operation to 90.71±2.22 at 6 months after operation. Knee joint activity was respectively (83.05±5.33)° and (132.05±7.15)° before operation and 6 months after operation. CONCLUSIONS: High strength wire under arthroscopy combined outside anchor nail in treating Meyers McKeever II, III ACL tibial check point has the advantages of less trauma, firm fixation, and satisfactory clinical effect.
