Abstract
OBJECTIVE: To investigate the effectiveness of non-absorbable suture cerclage combined with patella claw fixation for the treatment of inferior patella fractures. METHODS: Between September 2016 and January 2019, 22 patients with inferior patella fractures were treated. There were 12 males and 10 females, with a mean age of 49.1 years (range, 32-67 years). The causes of injury were traffic accident in 8 cases, falling in 12 cases, and other causes in 2 cases. The interval from injury to operation was 3-7 days (mean, 4.4 days). For the operation, 3 or 4 longitudinal tunnels were drilled backward from the surface of the proximal fracture fragment with Kirschner wires; under the guidance of lumbar puncture needles and steel wires, non-absorbable suture passed through the tunnels and encircled the inferior fracture fragment, then tighten to achieve a satisfactory reduction of the fracture; finally, the patella claw was used to strengthen the fixation. During the follow-up, complications were observed, maximum motion range of the knee joint was measured, X-ray examination was performed and fracture healing time was recorded. The knee function was evaluated according to Böstman scores. RESULTS: All the 22 patients were followed up 12-36 months (mean, 19.4 months). No infection, joint stiffness, bone nonunion, loss of reduction, or displacement of internal fixation occurred. All fractures were clinically healed, and the bone healing time was 2-3 months (mean, 2.6 months). At last follow-up, the maxium motion range of knee joint was 130°-135°, with an average of 132.6°. The Böstman score of the affected knee was 28-30 (mean, 29.2). All cases were graded as excellent results. CONCLUSION: Non-absorbable suture cerclage combined with patella claw fixation for inferior patella fractures has the advantages of simple operation, reliable fixation, and few complications, and the clinical results are satisfactory.
