Background: NT-PC-concentrator combined with absorbable suture can avoid displacement of fracture fragments in the internal fixation of patella fracture. Objective: To investigate the clinical effects of stabilizing comminuted patellar fractures with internal fixation by absorbable suture with NT-PC-concentrator. Methods: Fifty-three cases of fresh comminuted patellar fractures treated with internal fixation by absorbable suture with NT-PC-concentrator from October 2005 to December 2009. The demography of the 53 cases was as follow: 37 males and 16 females, ranging from 17 to 72 years old (a mean of 36.8 years old). According to AO classification, there were 8 cases of B3 and 45 cases of C2, C3. Results And Conclusion: Thirty-eight cases out of 53cases were followed up with a mean period of 8 months. All the 38 patients obtained bone union in 2-4 months. No case of implant loosening or refracture was found. Three cases of infected incision, 2 cases of postoperative Knee synovitis, and 1 cases of temporary aggravation of pre-existing osteoarthritis were documented as postoperative complication. Of the 38 cases, 30 cases were scored excellent under the Lysholm & Gillquist score, 6 good and 2 fair. The excellent and good rate was 94.7%. Absorable suture has better characteristics of mechanism in treating communited patellar fracture. It keeps fracture sites closely apposed and can fix bone fragments reliably. The NT-PC fixation is characteristics by a dynamic tension band mechanism. It serves the role of reduction and fixation simultaneously and can facilitate early postoperative range of motion exercises. Source
