Postoperative rehabilitation exercise
tenesmus
A mild rehabilitation plan was applied according to the rehabilitation of PCL. To protect the reconstructed PCL during rehabilitation exercises, shinbone tenesmus should be avoided. From the second week post-surgery, knee flexion training was performed twice a day and gradually increased to 90°. The knee flexion reached to 120° within 8 weeks and then expanded to its maximum degree. Only contact weight-bearing exercises with crutches were allowed within 6 weeks after the surgery, and full weight-bearing exercises with adjustable support of mathematical chuck were performed after the surgery for 10 weeks. Swimming and other mild exercises were allowed at 3 months post-surgery, jogging was allowed at 6 months post-surgery, and strenuous exercises were allowed at 12 months post-surgery.
