Arthroscopic treatment of tibial intercondylar ridge avulsion fracture with double-root line double tunnel fixation technique / 中国骨伤

ABSTRACT

<p><b>OBJECTIVE</b>To discuss arthroscopic technique of double-root line double tunnel fixation for tibial intercondylar ridge avulsion fracture and its short-term followvup observational results.</p><p><b>METHODS</b>From May 2012 to June 2017, 21 cases of tibial intercondylar ridge avulsion fractures were treated with arthroscope double line double tunnel. Among the patients, 16 males and 5 females were ranging in age from 17 to 45 years old, with an average of 29.6 years old, and injury to surgery time 3 to 6 days, with an average of 3.6 days. All the patients underwent arthroscopic exploration, fracture reduction, double root line fixation. The knee function was assessed at 3 and 6 months postoperatively using the Lysholm knee score, and the healing and resection of the patients were followed by X-ray examination.</p><p><b>RESULTS</b>All patients were followed up for 7 to 23 months, with an average of 12.8 months. All patients after fracture were bone healing, knee activity were gained their previous normal levels (ranged, 0° to 130 °), and no limb dysfunction. The average scores of Lysholm knee were(93.52±7.10) and(95.95±6.34) points in 3 months and 6 months after operation.</p><p><b>CONCLUSIONS</b>Arthroscopic treatment of tibial intercondylar ridge avulsion fractures with double root line is simple and reliable, and can provide an ideal internal fixation method for tibial intercondylar ridge avulsion fractures.</p>
