AbstractPatellar 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 (n = 23) were treated between December 2010 and February 2012 using conventional tension-band wiring, while patients in group 2 (n = 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 (p = 0.0038 and 0.011, respectively), with the implant removal period being significantly shorter as well (p = 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.

Aims and Objectives: Patellar fractures account for approximately 1% of all skeletal fractures. They are rare, but due to the crucial function of the patella in the extensor mechanism of the knee they can lead to a serious impairment. New data are revealing functional impairment remains common even with improved surgical techniques. The aim of this study is to asses the functional outcome of patients after revision surgery in case of secondary fracture dislocation or remaining articular incongruity. Materials and Methods: The study was designed as a retrospective observatory study. We included all patients who underwent a revision surgery because of a remaining articular incongruity or a secondary fracture dislocation or re-fracture from January 2010 until december 2016. Results: Sixteen patients of mean age 51,8 years were included in the study with a mean follow-up period of 28,8 months. Fifteen patients had AO type C fractures, within ten a C3 fracture. Thirteen were initially treated with tension band wiring via k-wires or cannulated screws. The reason for a revision surgery were 5 times a remaining articular incongruity, 11 times a secondary fracture dislocation or re-fracture. We analysed pain, satisfaction, range of motion, Böstman-Score, Tegner-Score and KOOS and could extract follow-up data from 15 of the patients. All fractures healed, no articular incongruity remained. Mean pain measured with the visual analogue scale (0-10) was at rest 0,57 (range 0-3,5), on exertion 2,79 (range 0-8). The measurement of the range of motion compared with the opposite knee showed a complete extension. Mean Flexion was 120°, in the opposite knee 136° (p = 0,05). Mean postoperative Böstman-Score and Tegner-Score were 25,11 (good, max. 30) and 78,67 (moderate, max. 100). KOOS: symptoms 66,8 points, pain 77,55 points, ADL 75,67 points and qualitiy of life 56,25 points. Conclusion: Early revision surgery in case of secondary fracture dislocation, re-fracture or remaining articular incongruity leads to statisfactory functional outcomes. Furthermore in case of complexe fractures the tension band wiring technique shouldn’t be the first choice, alternatives like the plate osteosynthesis should be considered.

Abstract Background Tension band wiring is the standard procedure for patellar fractures, but is associated with a high rate of implant related complications and implant failure. Tension band wiring may fail, especially with multifragmentary and comminuted fractures. Plate fixation of complex patellar fractures seems to be superior to wiring, both clinically and biomechanically. The aim of this study was to evaluate complications after locking plate fixation in patellar fractures two years after surgery and to access the functional outcome. Material and Methods As part of a prospective case series, all patients who had received locking plate fixation of a patellar fracture between April 2013 and May 2018 were clinically examined two years postoperatively and potential complications were evaluated. Results A total of 38 patients aged 19 – 87 years were included. Complications occurred in a total of five patients (13%), including one reactive prepatellar bursitis, one chronic infection and loss of reduction due to a dislocated pole fragment in three cases. The average active range of motion of the affected knee joint two years postoperatively was 133°. The Tegner activity scale score reached 3 points, the Lysholm score 95 points and the Kujala score 95 points. Conclusion With an overall relatively low complication rate and good clinical outcome, dislocated distal pole fragments are a common complication after plate fixation of patellar fractures. If preoperative diagnostic testing shows a pole fragment, a modified hook-plate can be used, with the possibility of fixing the pole fragment.

Prospective Randomised Study

BACKGROUND Patella is a sesamoid bone that plays an important role in the extensor apparatus of the knee joint. Fractures of the patella constitute about 1 % of all fractures. Definitive treatment of the patellar fractures depends on the type of fracture, displacement, joint congruity, and intactness of the extensor apparatus. There is significant controversy about the surgical options for displaced patellar fractures. Although conventionally tension band wiring using K-wires (TBW-K wire) is a common procedure, tension band wiring using cancellous screws (TBW-CCS) is gaining popularity. A study was undertaken to compare outcomes between the two procedures (TBW-CCS & TBW-K wire). METHODS A prospective randomised study was planned. Inclusion & exclusion criteria were laid down. Institutional ethical committee clearance was obtained. 68 consenting patients with transverse patellar fractures underwent surgery (TBW-CCS or TBWK wire) after randomisation. Demographic, clinical, and radiological assessment was done. Bostman score was used as an outcome measure. Statistical analysis was done. RESULTS 85.5 % of cancellous screw group patients had excellent outcome scores as against 41.2 % in the K wire group. The difference was statistically significant. 5.8 % of patients in the cancellous group complained of implant prominence as against 17.6 % in the K wire group which was statistically significant as well. Patients in TBW-CCS had a statistically significant difference in Bostman scores at 6 weeks, 3 months, and 6 months. CONCLUSIONS Tension band wiring with cannulated cancellous screws is a safe and reliable technique in the management of transverse patellar fractures with fewer chances of implant failure and soft tissue irritation. Based on our study, tension band wiring with cannulated cancellous screws is a better method to treat transverse fractures of the patella when compared to the modified tension band wiring technique using K-wire.
