Soft Tissue Expansion in Total Knee Arthroplasty Due to Extensive Scarring and Fibrosis in Multiple-Operated Knee.

Background: Inadequate wound closure is a feared complication following total knee arthroplasty (TKA). A knee with a multiple operative history, excessive scarring, and fibrosed surrounding soft tissue presents a significant challenge. In cases with preoperative uncertainty for sufficient soft tissue coverage because of ischemia and tension on closure, soft tissue expansion (STE) has been reported to be an effective tool for optimizing successful closure. Case Report: For the case in this report, STE was performed on a knee with multiple scars, potential ischemia, fibrosis, and soft tissue contractures prior to TKA. Conclusions: In cases of uncertain soft tissue coverage in TKA, the use of STE can be a useful method in creating adequate wound closure.
