Biomechanical comparison of tension band- and interfragmentary screw fixation with a new implant in transverse patella fractures

Abstract Background Modified tension band fixation has become commonly used for transverse patella fractures. The conventional stainless steel wire provides sufficient stability but may be associated with complications. Objective The study aimed to evaluate the effectiveness of a new modified tension band fixation technique for transverse patella fractures using a nonabsorbable suture. Material and methods We present the result of a prospective series using a nonabsorbable suture (FiberWire) for transverse patella fractures. The mean follow-up period totaled 12 months. A total of 16 patients were evaluated by radiographic and clinical review. The postoperative clinical evaluation employed Lysholm and Böstman scores. Result All clinical results on follow-up were good to excellent. Minimal intra-articular joint stepping and further fracture displacement were recorded. No patient needed re-operation, and functional outcomes of the knee were satisfactory. No significant differences were found between the injured and contralateral knee range of motion. No symptomatic implants and skin complications were noted, and all fractures were completed heal within 15 weeks. Conclusion FiberWire provided sufficient stability and reduced postoperative complications. The results proved appropriate, and the technique has merit, as it obviates the need for re-operation.

A Prospective Study

Patella fractures accounts for 1% of all skeletal injuries. Patella fractures usually need to be treated with accurate reduction and fixation to obtain optimal knee function. Improper reduction of the articular fragments leads to complications like arthritis and quadriceps dysfunction. Tension band wiring and pasting are commonly performed fixation methods. Tension band wiring with K-wires is associated with wire prominence and soft tissue irritation. Cannulated cancellous screw fixation of the fracture and tension band wiring through the cannulated screws avoid the complication of wire migration and breakage. In our study, we fixed these fractures with cannulated cancellous screws and tension band. This is a prospective study done in SRMC from 2012-2017. A total of 17 Patients with transverse patella fracture are taken into a study, 4mm cannulated cancellous screws with 18 mm stainless steel wire is used for anterior tension band wiring. Extensor retinaculum closure is done for all these patients. All patients had excellent knee function, according to KSS. There was no case of implant prominence or soft issue irritation in any of these patients. One patient had extensor lag. Cannulated cancellous screw with anterior tension band wiring is a reliable, effective and reproducible technique in treating transverse patella fractures.

ObjectivePatella fractures in children are rare, with an incidence of less than 1% of all pediatric fractures. Literature describes different surgical techniques and outcomes, but there is not a specified superior technique for children. The aim of this study is to assess the functional outcome after screw fixation of transverse patella fractures in children.MethodsTwo boys at 11 years of age were presented with a transverse fracture of the patella within the same week. Open reduction and fixation of the fractured patella with periost sutures and a 4.0 mm titanium screw inserted from the distal fragment. Afterward, the quadriceps expansion was meticulously repaired with sutures.ResultsThe patients could fully weight bear immediately on a fully extended knee in an orthosis. After 4 weeks, radiological healing was obtained. At the 8-week and 6-month follow-up, the modified Hospital of Special Surgery knee score was 100 points in both patients.ConclusionSingle screw fixation provides an excellent outcome after 8 weeks with a full range of motion and full weight bearing, providing a faster recovery.
