Maximum tensile strength is recovered in wound area during what period after an injury?

Net collagen accumulation, however, depends not only on increased collagen synthesis but also on decreased degradation. When sutures are removed from an incisional surgical wound, usually at the end of the first week, wound strength is approximately 10% that of unwounded skin. Wound strength increases rapidly over the next 4 weeks, slows down at approximately the third month after the original incision, and reaches a plateau at about 70% to 80% of the tensile strength of unwounded skin. Lower tensile strength in the healed wound area may persist for life. Ref: Robbins 8th edition Chapter 3.
