Abstract

• Material and Methods
  The strip of flexor tendon was harvested and divided 2 pieces and repaired with interrupted suture. The knee joit then opened medially through a small incision and repaired tendon strip was transplanted into the open knee joint. After 2 weeks(n=10), 4 weeks(n=10), 6 weeks(n=10) and 8 weeks(n=10), the sutured tendon was removed from the joint and examined histology and measured tensile strength.
• Results
  Mactoscopically the surface of all piece was smooth and glistening. Fibroblasts were appeared in the sutured gap and produced collagen fiber and after 6 weeks many portions of collagen fibers were maturated. The gain of tensile strength was proportional to the time till 8 weeks.
  The findings indicate that diffusion of nutrients may be important for the survival and reconstresstablishment of the microcirculation.
