Abstract

• Materials and Methods
  Flexor tendons on both lower extermities were divided and repaired with mersilene 4-0 in rabbits and after 2,4,6,8, weeks we obtained the pieces of tendons and have studied the histologic changes and measured tensile strength as time passed.
• Results
  Histologically fibrobalst-like cells were proliferated on the epitenon and migrated into the suture site and produced collagen fibers in the central area. Tensile strength was proportionately increased until 8 weeks and well correlated with histologic findings.
  In conclusion, healing of the repaired tendon was initiated on the surface area and gained tensile strength with time passed.
