What’s New in Musculoskeletal Tumor Surgery

Autologous menisci–cruciate ligament composite as a flap for soft tissue reconstruction following malignant bone tumor resection around the knee

“…Coupled with multidisciplinary approaches, limb salvage is now performed for nearly 90% of appendicular malignant bone tumors 1 . Complete surgical resection with negative margins is the gold standard for both local control and overall survival 2 . However, obtaining negative surgical margins may require extensive resection, causing prominent soft tissue defects and functional deficits 3 .…”

“… 1 Complete surgical resection with negative margins is the gold standard for both local control and overall survival. 2 However, obtaining negative surgical margins may require extensive resection, causing prominent soft tissue defects and functional deficits. 3 Although muscle or fasciocutaneous flaps generally provide favorable coverage, sometimes they do not, and then supplementary soft tissue is required to obtain adequate coverage.…”

“…Results: Fourteen patients were treated with vascularized composite transfer (10 distal femurs and 4 proximal tibias) and 26 patients with free composite transfer (19 distal femurs and 7 proximal tibias). The composite can be used to cover the area of soft tissue defect from 22 to 48.38 cm 2 (34.67 ± 6.48 cm 2 ). With contrast-enhanced ultrasound, peripheral rim healing and dotted blood flow signal at the side of anastomosis were detected on a patient 16 months after free composite transfer.…”
