Abstract
BackgroundModified 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.ObjectiveThe study aimed to evaluate the effectiveness of a new modified tension band fixation technique for transverse patella fractures using a nonabsorbable suture.Material and methodsWe 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.ResultAll 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.ConclusionFiberWire provided sufficient stability and reduced postoperative complications. The results proved appropriate, and the technique has merit, as it obviates the need for re-operation.

Summary
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. Patella fracture incidence is relatively uncommon, representing approximately 0.5 to 1.5% of all skeletal injuries [1, 2]. Two different mechanisms can cause patella fractures. The most common is a direct impact on the anterior side of the knee. The remaining cases are caused by indirect injury with eccentric contraction of the forceful quadriceps muscle. One-third of those patients require a surgical intervention [3].
