title: Management of chronic achilles tendon infection with musculotendinous gracilis interposition free-flap coverage.
abstract: Management of infected Achilles tendon repair poses a significant reconstructive problem. Thorough debridement is most important and resection of non-viable tendon substance is required. Reconstruction of such tendon defects requires vascularized soft-tissue coverage that is stable and that offers the possibility of functional restoration. Gracilis free-tissue transfer is an effective means of providing stable, durable, well-vascularized, soft-tissue coverage in an infected Achilles tendon repair. The microsurgical anastomoses are technically straightforward. Cybex II dynomometer measurements, performed 6 months following free-tissue transplantation, revealed strength (torque) and power, at an angular velocity of 45 degrees per second, of: 59 percent and 52 percent, respectively, compared to the uninjured side. Endurance was assessed at an angular velocity of 120 degrees per second over a 15-second test interval, and was noted to be 81 percent, compared to the normal ankle. Excellent functional results and acceptable soft-tissue contour can be expected with this technique.
