“…Moreover, the excellent pliability meant that the cables conformed to the bone surface better after tensioning, providing more reliable stability and decreasing the known complications associated with stainless steel wire. 22,23 Thus, in the present study, patients treated with MTTB had better knee function at 3 and 6 months postoperatively, and a lower complication rate, even in the two patients who received revision surgery due of fixation failure. The present authors believe that this technique can be used for patellar fractures, including patellar revision surgery.…”

Objective To compare a modified two-tension-band (MTTB) technique with the AO tension band in treating patellar fractures. Methods This retrospective study included patients treated with AO tension band (group 1) or MTTB (group 2). Data obtained during serial follow-up evaluations of time to bony union, range of motion (ROM), Hospital for Special Surgery (HSS) score and complication rates, were analysed. Results Fractures healed in all 51 patients included in the study (group 1, n = 28; group 2, n = 23), with no statistically significant between-group difference in time to bony union. Regarding function results, group 2 had better HSS scores at 3 and 6 months postoperatively; however, at 1 year postoperatively, both groups had similar HSS scores and achieved acceptable flexion and ROM. The overall complication rate was significantly lower in group 2, but average costs were higher in group 2 versus group 1. Conclusion MTTB provides secure fixation and improved knee function at 3 and 6 months postoperatively, and has a lower complication rate with early mobilization, compared with the AO tension-band technique.

“…Implant migration of > 2 mm has been reported in 4.7 to 22.0% of cases and indicates implant failure. 14,15,17 Although ring pin TBWT prevents implant migration, 10 one case of implant migration was observed in group 2, which was thought to have been due to an inappropriate procedure. In that case, removal of the implant was not required because the ring pin restricted its migration.…”

Complications Related to Implant Fixation of Patellar Fractures: Comparison of Ring Pins versus Bent K-Wires

2016

Patellar fractures are characterized by injuries to the extensor and typically require surgical fixation. Among the methods used for fixation, the most common is the modified AO tension-band wiring technique. However, using this technique, implant migration occurs due to the lack of connections between the K-wires and the tension-band wire, which causes irritation and reduces fracture stability. Recently, new methods for tension-band wiring have been developed in which tension bands lock the K-wires through an attached "ring" to prevent migration. The purpose of this study was to compare the clinical outcomes when either the conventional or novel technique was used for tension-band wiring. This was a retrospective study involving 48 patients who underwent tension-band wiring to correct a patellar fracture. Patients in group 1 ( = 23) were treated between December 2010 and February 2012 using conventional tension-band wiring, while patients in group 2 ( = 25) were treated between March 2012 and May 2014 using the novel ring pin method. Different surgeons performed the operations in the two groups, while all other conditions were consistent. The surgical outcomes were assessed according to the level of implant migration, irritation, and implant removal procedures. All patients in group 2 achieved a union of the patella, while two patients in group 1 did not. These two patients underwent partial patellectomy within 1 year of the initial surgery. Implant migration and removal were significantly more common among patients in group 1 ( = 0.0038 and 0.011, respectively), with the implant removal period being significantly shorter as well ( = 0.005). The novel ring pin method was superior to the conventional method in terms of preventing implant migration, removal, or other secondary operations for the correction of complications.

“…15 Successful fixation depends on adequate strength to allow early knee functional exercise and ultimate restoration of knee function. 16 In nondisplaced patellar fractures, the use of a plaster cast is accepted. 17 Displaced patellar fractures, defined as those with a >5-mm gap between fragments or an articular step-off of 19,20 The K-wire tension band is a traditional, classical surgical method for treating patellar fractures, 21 and this status means it has a relatively reliable biomechanical fixation effect and can effectively convert tension stress into compressive stress.…”

Comparison of the Kirschner Wire Tension Band with a Novel Nickel–Titanium Arched Shape–Memory Alloy Connector in Transverse Patellar Fractures: A Retrospective Study

et al. 2020

This study aims to compare the clinical outcomes of the nickel–titanium arched shape–memory alloy connector (hereafter referred to as the ASC) and tension band fixation for the treatment of transverse patellar fractures. We retrospectively analyzed a total of 257 patients with transverse patellar fractures who were treated at our emergency orthopaedics department from March 2010 to March 2017. Either an ASC or the Kirschner wire (K-wire) tension band had been used to treat these fractures according to surgeons' experience and preference. We compared operative details, postoperative recovery, and postoperative knee function at 6 months. In terms of surgical duration, blood loss, incision length, length of hospital stay, and postoperative complications, patients in the ASC group showed significantly better results than patients in the K-wire group (p < 0.05). There were no significant differences between the two groups in terms of fracture healing time, knee mobility, and the Boström score at the postoperative 6-month evaluation (p > 0.05). Though, there were similar functional outcomes between two groups whose transverse patellar fractures were different methods, we found that the ASC method was a more reliable, more minimally invasive, and safer treatment option than the tension band wiring method using K-wires, resulting in less tissue damage, shorter surgical duration, shorter length of hospital stay, and fewer complications.
