Dynamic traction and fixing apparatus in repair of old rupture of patellar tendon / 中华创伤骨科杂志

ABSTRACT

Objective To explore an effective method of repairing the old rupture of patellar tendon. Methods We designed a new 井-shaped apparatus for traction and fixing which was to be used, under the dynamic conditions, to reduce the patella, loosen the quadriceps m. of thigh, repair the tendon of knee cap and facilitate postoperative exercises with the fixing apparatus on. Results We used the apparatus to repair the tendon of knee cap in 6 cases. The follow up of 8 to 56 months (averaging 26 months) showed that their functions of the knee joint were all satisfactory. Conclusions The 井-shaped external fixation device can be used under the dynamic conditions to repair the old rupture of patellar tendon with the advantages of little contracture of the knee cap and quadriceps m. of thigh, easy fixation after repair and suture, and early exercise of the knee joint. This novel method is simple and recommendable.
