A comparative study of tension band wiring and encirclage in treating transverse fractures of patella

Abstract

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.

Clinico-radiological and functional outcome of surgical management of displaced transverse fracture of patella in adults managed by tension band wiring in a tertiary care hospital in North India: a prospective study

“…14,15 But after application of tension band wiring technique chances in the articular surface distraction are not seen and early mobilization can be started as noted by Levak et al 16 In the present study, maximum incidence was observed in 4 th decade with mean age of trauma was 41.4 years, which has similar results as compared to Mohapatra et al (37 years), Mahindra et al (40.46 years), and Yang et al (63.73). [17][18][19] Fractures were more common on the right side (59.1%), than on left side (40.9%) which were in agreement with previous studies Asimuddin et al and Mahindra et al 18,20 In the present study, 17 (%) were males and 5 (%) were females, with male to female (M: F) ratio of 3.4:1. Similar observations were made by Asimuddin et al, Ramu et al and Lone et al [20][21][22] In our study, the most common cause of fracture was road traffic accident (%), followed by fall (%), and assault which was similar to previous studies Asimuddin et al, Mohapatra et al and Mahindra et al 17,18,20 Table 3: Time of radiological union.…”

“…Similar observations were made by Asimuddin et al, Mohapatra and Mahindra et al 17,18,20 The functional outcome was assessed on the basis of Reich and Rosenberg scale. 17,20,22 Out of 22 patients, complications were observed in 6 (27.3%) patients. Superficial Infection was noted in 3 patients, which was managed by thorough wound wash, intravenous antibiotics and regular sterile dressings.…”

“…Average time of union (weeks) Asimuddin et al 20 10 (8-12) Mohapatra et al 17 13.6 Mahindra et al 18 12.7 Present study 12.4 Radiological union was achieved within 10 to 16.2 weeks, with an average of 12.4 weeks. Similar observations were made by Asimuddin et al, Mohapatra and Mahindra et al 17,18,20 The functional outcome was assessed on the basis of Reich and Rosenberg scale. 17,20,22 Out of 22 patients, complications were observed in 6 (27.3%) patients.…”

Functional Analysis of Fracture Patella Managed with Tension Band Wiring

“…Over the time it decreased significantly. These results of our study were similar to the study conducted by Subhrat Mohapatra and Pulin Bihari [8].…”
