Abstract
To evaluate the angle of modified anchor nail placement and the curative effect of double pulley technology for the treatment of extreme avulsion fracture of lower patella. From December 2015 to December 2018, a total of 22 patients(10 males and 12 females) with avulsion fracture of the inferior pole of patella were retrospectively analyzed. The average age was (44.00±15.24) years old(range, 19 to 70 years). All patients were treated with modified anchor angle and double pulley technique. The range of motion(ROM) and Bostman score system were used to evaluate the functional recovery of knee joint. All 22 cases were followed up with an average of (30.86±8.00) weeks (18 to 46 weeks). At the last follow-up, ROM of the affected knee was (130.82±4.69) °, and the contralateral knee was (133.23 ± 3.15) °, there was no significant difference between two groups (P>0.05). The average Bostman score was (28.45±1.41) scores, 18 cases were excellent results, 4 cases were good. Improved anchor placement angle and double pulley technique for treatment of extreme avulsion fracture of lower patella is easy to operate, with satisfactory curative effect and good recovery of knee joint function.
