Effect Of Hollow Screw Combined With Suture Anchor In Treatment Of Tibia Avulsion Fracture Of Posterior Cruciate Ligament

Objective: To investigate the curative effect of hollow screw combined with suture anchor on tibia avulsion fracture of knee posterior cruciate ligament.Methods: 17 patients with tibia avulsion fracture of knee posterior cruciate ligament(PCL)from the department of orthopaedics the second affiliated Hospital of Chongqing Medical University from March 2010 to in February 2014.There were 12 males and 5 females,with a mean age of 38.7 years(range,19-56 years).The causes of injury include traffic accident 8 cases,sporting injury 5 cases and falling down 4 cases.According to Meyer-Mc Keever parting,type 1 in 2 cases,type 2 in 8 cases,type 3 in 7 cases.They were treated well by hollow screws combined with suture anchors.Using external fixation support to avoid excessive activity after the surgery,flexion and exercise after the wound healed,partial weight-bearing after 4 weeks and weight bearing slowly after 6-8 weeks out of the protect from external fixation support.The curative effect was evaluated by Lysholm points-scoring system.Results: In the postoperative follow-up survey for 6 to 12 months.Primary healing of incision was obtainted,without infection,neurovascular injury and deep vein thrombosis(DVT).Bone healing took an average of 4.2 months(range,3-6months).We don't find hollow screw and suture anchor loose.The result of Lachman test were negative and Lysholm point –scoring system showed 15 excellent cases and 2good cases.Conclusion: Hollow screw combined with suture anchor is easy to learn and operate for the treatment of tibia avulsion fracture of knee posterior cruciate ligament Simultaneously,the patients will be more satisfied and get better functions from early rehabilitation training.
