“…This bending load results in tension at the anterior surface of the patella, which is maximum at near 45° of knee flexion and may rise to 6000 Newtons in young trained men. 5 Considering the magnitude of tension, three-point bending stress and compressive forces that occur on the posterior surface of the patella in a loaded flexed knee, the prevalence of patellar fracture is high and have an important effect on the efficacy of various methods of treatment of these fractures.…”

Background: The functional and radiological outcome of the union of transverse fractures of patella treated by tension band wiring (TBW) and encirclage wiring were compared according to WEST’s criteria.Methods: During three years, 44 patients with displaced transverse fracture patella were treated randomly either by TBW or encirclage with twenty-two patients in each group. Two patients in each group were lost to follow-up.Results: Results were compared based on the period of union, post-operative complications, early mobilization and recovery to pre-injury level. Fractures united at an average of 13.6 weeks with 8-12 and 10-14 weeks in TBW and the encirclage group, respectively. Results were excellent in 65%, good in 25% and poor in 10% cases in TBW group, as compared to the encirclage group with excellent in 50%, good in 30% and poor in 20% cases. In TBW group, 75% cases had a full range of motion (ROM), 15% had >120° of flexion and 10% had flexion between 90° and 120°, as compared to 50% full ROM, 30% >120° of flexion and 20% between 90° and120° flexion in the encirclage group. A case of migration of pin and another case of limitation of flexion by 25° were noticed.Conclusions: Patients treated with TBW had better results than the encirclage in the management of transverse fractures of the patella.

“…The incidence of inferior pole fractures of patella is around 5% and the various treatment options include tension band wiring, circumferential wiring, or use of screw 1 . The traditional recommendation for severly comminuted inferior pole fractures is excision of the comminuted pole followed by reattachment of the patellar tendon with transosseous suture to the superior fragment 2 .the superior fragment is an important part of extensor mechanism and should be preserved,the details of suture of patellar tendon to the superior fragment should be done carefully to prevent a tilt of the fragment which can cause erosion of the patellar groove 3 .…”

“…Currently, the usual surgical intervention for treatment of transverse patella fractures is open reduction with a sufficient incision and internal fixation using a K wire with the modified tension band method [5,6,18]. However, this approach is associated with delayed wound healing, postoperative adhesions, knee stiffness, and prolonged work disability [1,19].…”

Background The cable pin system is an effective device for fixation of transverse patella fractures. However, whether this device provides superior results using a minimally invasive technique instead of conventional open surgery using the K wire tension band method is unclear. Questions/purposes We asked whether a minimally invasive technique would be associated with (1) increased operative time; (2) reduced postoperative pain; (3) faster recovery of ROM; (4) higher knee scores; and (5) reduced complications. Methods Forty patients with displaced transverse fractures of the patella participated in this prospective, randomized, controlled trial. Twenty of these patients underwent a minimally invasive technique and the others had conventional open surgery using K wires. Some data for six of the 20 patients who underwent the minimally invasive technique were published in an earlier prospective, observational trial. At postoperative intervals of 1, 3, 6, 12, and 24 months, pain was measured by VAS scores, active flexion and extension of the knee were measured in degrees by goniometry, and knee function was evaluated using the Böstman clinical grading scale. Results Operative time was longer in the minimally invasive surgery group (54.3 ± 9.8 minutes versus 48.5 ± 6
