<prompt> The normal tensile strength of tissue at the site of wound is gained after-One week of wound healingTwo weeks of wound healingTwo months of wound healingNone  <response>: Ans. is NoneWound strength At the end of first week, wound strength is approximately 10 that of normal skin.Strength increases rapidly over the next 4 weeks.At the end of third months, the strength reaches a plateau of about 70 to 80 of the normal skin, a condition that may persist for life.So, Remember following factsTensile strength never reaches the normal strength of unwounded tissue i.e., 100.Maximum strength is achieved by the end of 3 months.Maximum strength is 70-80 of normal tissue.How does tensile strength change with time ?During first 2 months it is due to excess collegen deposition.After that it is due to structural modification of collegen, i.e., cross-linking, increased fiber size.
