Abstract:

BACKGROUND: The treatment method of tibial avulsion fractures of anterior cruciate ligament is varied; each has its advantages.

OBJECTIVE: To investigate the methods and clinical effects of the treatment of avulsion fractures of tibial insertion of anterior cruciate ligament by the means of making two decussate lines and four strands of non-absorbable Arthrex sutures passing through two bone tunnels combined with pushlock free knotting anchor under arthroscopy.
METHODS: From December 2014 to November 2015, 23 cases of avulsion fractures of tibial insertion of anterior cruciate ligament were treated in the Second Hospital of Inner Mongolia Medical University. Under the arthroscopy, avulsed fracture was fixed in tibial intercondylar eminence by the means of making two decussate lines of Arthrex sutures passing through. At the same time, pushlock free knotting anchor beside tibial tubercle provided a tightening of tension for Arthrex sutures, which could strengthen the fixation of avulsion fracture blocks. Knee joint Lysholm and Tegner scores were followed up. Knee stability was evaluated by anterior drawer test and Lachman test. Postoperative reset and healing were evaluated with X-ray films. 

RESULTS AND CONCLUSION: (1) All 23 patients were followed up for 6 months to 1 year. (2) Lysholm scale of the knee function was (47.31±6.16) preoperatively and (94.69±1.28) postoperatively (P < 0.05). Tegner score was (3.14±1.58) preoperatively and (7.74±1.69) postoperatively (P < 0.05). (3) Lachman test of all cases was negative. X-ray films demonstrated that fracture healing was good. There was no repeated swelling or cross locking of the joint. The knee was not limited by flexion or extension. No infection or deep venous thrombosis of lower extremity occurred. (4) The method of Arthrex sutures passing through two bone tunnels combined with pushlock free knotting anchor under arthroscopy has the advantages of minimally invasive, simple operation, reliable fixation, no metal implants and satisfactory result to treat the tibial intercondylar eminence fracture of anterior cruciate ligament.
