Patella Fracture Treatment
Treatment of patellar fracture, should be to maximize the restoration of the smooth articular surface, to give a more solid fixation and early knee joint activity to prevent the occurrence of traumatic arthritis.
1. Gypsum-based care or possession of a fixed
This law applies to a non-displaced patellar fracture, without manual reduction, intra-articular blood out, bandage, care, or with long legs plaster cast limb fixed in extension position 3 ~ 4 weeks. Cast immobilization in the quadriceps contraction during the exercise, remove the plaster after care knee activity practice.
2. Open reduction and fixation
Fixation of patella fractures multiple methods can be divided into two categories, one category of fixed-line still needs a certain period of time after the external fixation; the other relatively strong internal fixation without external fixation.
1) Modified tension band wire fixation
2) Patella or on the lower pole resection, re-quadriceps tendon surgery
3) Patella resection
Reduction should not apply, should not severely comminuted fracture of partial resection. Comminuted fracture block resection should try to protect their quadriceps aponeurosis and periosteum. Suture after excision of the expansion of the Department of tearing and joint capsule to restore to normal tightness. Then, drop the quadriceps tendon and patellar tendon suture. Can not direct suture, and can be reversed quadriceps tendon suture repair. Make up the quadriceps tendon in the "V"-shaped incision, to cut under the flap over the tendon, patellar excision repair of the defect after the new form. Vastus lateralis muscle can also be used and the quadriceps tendon of the lateral tendon flip down flap excision repair defect of the patella Department. After four weeks of fixed plaster care and practice activities flexed knee.
